Product Overview
A business entrance has to manage two different needs at the same time. It must allow authorised people to enter efficiently, yet it must also give staff a controlled way to communicate with visitors, contractors and delivery teams before the door is opened. A conventional bell only announces that somebody has arrived. It does not connect the entrance to an IP phone system, identify cardholders, accept a keypad code or form part of a documented access workflow. The Grandstream GDS3705 addresses that gap by combining an IP audio intercom with credential reading and door-control interfaces in one robust endpoint.
The device is purpose-built for audio-only projects. It uses integrated dual microphones and a 2-watt HD loudspeaker with echo-control technology so a visitor can speak with reception, security, a resident, a service desk or another configured SIP destination. This is especially useful where visual verification is already provided by a separate CCTV camera, where privacy rules discourage a camera at the door, or where the project budget and operating process do not require embedded video. By separating the audio intercom role from camera monitoring, buyers can retain a straightforward entry workflow without purchasing functions they will not use.
Access can be granted through the built-in 125 kHz RFID reader, the illuminated metal keypad or a configured remote-release process. The unit includes two relay outputs that can participate in a correctly designed electric-lock or alarm circuit, together with optocoupler inputs for low-voltage devices such as a door sensor. RS485 and 26-bit Wiegand input and output interfaces provide additional integration paths. These connections make the unit more than a network doorbell, but they also mean the project must be planned carefully. Lock voltage, current, fail-safe or fail-secure behaviour, emergency release, door contacts and life-safety rules should be confirmed by a qualified installer.
For African businesses, a practical purchase decision must consider weather exposure, public reach, network reliability, PoE capacity, mounting surface, power protection, credential quantities and the receiving communications platform. The zinc-alloy enclosure, IP66 protection and IK09 resistance support demanding entrances, while the operating range of -30°C to 60°C provides flexibility for many deployment conditions. FourTeck helps procurement teams connect these technical points to the real business process so the quotation includes the door station, suitable accessories and clearly stated support terms rather than only a model number.
Key Business Benefits
The value of an IP door station comes from the way it improves daily entrance handling. The following benefits connect the GDS3705 feature set to practical outcomes for facilities, IT, security and procurement teams.
◆ Clear Visitor Communication
Dual microphones and an HD loudspeaker help staff communicate with people at the entrance before granting access. This can reduce unnecessary movement by reception or security personnel and gives visitors a more organised way to explain their purpose.
✓ Multiple Entry Workflows
RFID credentials suit regular users, keypad codes can support controlled PIN entry, and SIP calling enables supervised visitor access. A business can apply different processes to employees, residents, contractors and guests instead of treating every arrival in the same way.
↗ Uses the IP Network
SIP and Ethernet connectivity allow the entrance to become part of the organisation’s communication environment. Calls can be directed to compatible phones or PBX destinations, reducing dependence on a separate proprietary intercom handset infrastructure.
⚙ Simplified Cabling with PoE
IEEE 802.3af Class 3 PoE can carry network data and device power over one Ethernet connection. This can simplify installation where a suitable switch or injector is available, while still allowing a separate 12VDC option when the design requires it.
🔒 Rugged Entrance Endpoint
The metal construction, IP66 rating and IK09 resistance help the unit withstand outdoor exposure and public-access conditions when it is installed correctly. This supports a longer-term access design in offices, campuses, residences and operational sites.
● Practical Integration Options
Relay, optocoupler, Wiegand and RS485 interfaces allow the unit to participate in suitable lock, sensor and access-control designs. Buyers can align the door station with existing infrastructure rather than assuming a completely isolated installation.
These benefits depend on correct configuration. The door station cannot compensate for an unsuitable lock, poor cabling, insufficient PoE, weak network security or an unsupported receiving phone. FourTeck therefore encourages buyers to define the full entrance workflow before approving the order. This creates a better basis for cost control because required accessories and installation responsibilities are identified early, while optional components can be separated from essential items.
Product Highlights
The GDS3705 is intentionally focused. It does not include a camera, Wi-Fi radio or modern mobile credential technologies found on newer video models. That focus can be an advantage for projects that already have separate surveillance, need a simpler audio entrance, or want to integrate with existing SIP phones and 125 kHz credentials. Buyers who require visual verification, QR codes, NFC, Bluetooth or newer cloud-assisted workflows should compare another model in the Grandstream GDS family before ordering. FourTeck can help separate must-have functions from attractive but unnecessary features.

Use the table as a selection reference rather than a substitute for installation design. The published electrical ratings describe the device interfaces, but they do not automatically prove compatibility with a specific magnetic lock, strike, gate motor, alarm panel or controller. The project team should identify the lock voltage and current, power supply, fail mode, emergency release, sensor arrangement and legal requirements before wiring begins. Network planning is equally important. Check cable distance, outdoor-rated pathway, surge exposure, PoE source, voice VLAN, firewall rules, SIP registration, time synchronisation and administrator access. Buyers replacing an older intercom should also compare mounting dimensions and credential technology, because the new unit may not reuse the existing cards, wall opening or lock wiring without changes.
Configuration and Buyer Guidance
A reliable quotation starts with the entrance workflow. Describe who will use the door, how they will identify themselves, who answers a visitor call, how the lock is released and what should happen when power or the network is unavailable. This information reveals whether the project needs only the GDS3705 or a wider package containing credentials, a PoE switch, power supply, exit button, door contact, electric lock, receiving phones, PBX configuration and installation services.
1. Define the User Groups
Count employees, residents, contractors, visitors and administrators. Decide which groups receive RFID cards, which use PINs and which must call for supervised entry.
2. Confirm the Call Destination
Identify the PBX, extension, ring group, IP phone or security desk that will answer. Check codecs, DTMF method, schedules, forwarding and remote-release commands.
3. Review the Door Hardware
Provide the door type, lock model, voltage, current, fail mode, exit button, sensor and emergency-release requirement. These details determine the circuit and accessory list.
4. Check the Network
Confirm Ethernet availability, PoE budget, cable length, VLAN, IP addressing, firewall rules, backup power and whether the station must communicate across sites.
5. Plan Credential Administration
Decide who enrols cards, assigns PINs, removes former users, backs up data and reviews permissions. A technical feature only delivers value when ownership is clear.
6. Set Installation Scope
Clarify whether the order covers equipment only, remote configuration, on-site mounting, lock wiring, PBX setup, testing, documentation or user handover.
Future needs deserve attention as well. A single-door installation may later expand to several entrances or branches. Standard naming, credential formats, call routes, network rules and documentation can make that growth easier. However, buyers should not force the same model onto every entrance when some locations require video, mobile credentials or a different environmental design. FourTeck can help compare the audio-focused GDS3705 with other Grandstream facility-access options and prepare a bill of materials matched to the site rather than a generic bundle.
Ideal Business Use Cases
The device is suitable where a controlled entrance needs reliable voice communication and electronic access but does not require an integrated camera. The final design must still match the lock, network, security policy and operating procedure.
Corporate Reception Entrances
Visitors can call reception or a security desk, explain the purpose of the visit and wait for remote release. Employees can use RFID or assigned PINs, reducing the need for reception staff to leave the desk for every arrival.
Apartment and Managed Property Doors
Residents or authorised staff can use credentials, while guests call a resident, concierge or property team. The design should account for resident turnover, lost cards, shared PIN risks and after-hours call routing.
Schools and Training Centres
A controlled front door allows administrators to speak with parents, applicants, suppliers and service personnel before entry. Staff credentials can support routine access while visitors follow a supervised process.
Clinics and Healthcare Offices
Staff-only areas, dispensaries, records rooms or after-hours entrances may use managed credentials and an intercom to protect restricted spaces while maintaining communication with authorised visitors.
Warehouses and Logistics Sites
Drivers, contractors and temporary workers can call dispatch or security at a personnel or delivery entrance. Rugged construction suits exposed locations, while card access supports permanent teams.
Hotels and Staff-Only Areas
Back-of-house doors, service entrances and controlled operational zones can use staff credentials, with supervised admission for vendors and maintenance teams. Shift patterns and temporary staff require clear credential rules.
Retail and Branch Offices
Stock-room doors, cash-office entrances and staff access points can be separated from public customer areas. A standard SIP and credential approach can simplify support across several branches.
Technical and Equipment Rooms
Server rooms, communications closets and utility areas may benefit from managed card access, door status input and communication with an operations team, alongside CCTV and documented authorisation procedures.
The station is not the right answer for every doorway. High-risk entrances may require video verification, biometric credentials, anti-passback, advanced reporting or integration with a broader enterprise access platform. A gate may need different relays, surge protection or long-distance network design. Accessibility requirements may also influence mounting height, audio levels, signage and alternative entry methods. FourTeck can review these factors before recommending the model, an alternative or a complete access solution.
Grandstream GDS3705 HD Audio and SIP Intercom
The first task of an audio door station is to make a conversation understandable at a location that may be noisy, reflective or exposed. The GDS3705 uses two microphones, a 2-watt HD speaker, acoustic echo cancellation and noise-control functions to support two-way communication. Published ranges indicate audio capture up to approximately 1.5 metres and output up to approximately 3 metres. These figures are useful planning references, but real performance depends on mounting position, background traffic, wind, walls, canopy design, visitor distance and the audio settings used during commissioning.
SIP support connects the entrance to a compatible IP communications environment. A visitor can press the call key and reach a configured phone, extension, ring group or service point. During business hours, the destination might be reception. At night, the PBX may direct calls to security. A warehouse entrance can call dispatch, while a residential property can route calls according to the chosen operating model. This flexibility is valuable because the same network that supports business telephony can also help manage visitor communication.
Compatibility should be proven, not assumed. The receiving phone or PBX must support the required codec, DTMF method and door-release workflow. G.711 and G.722 provide familiar audio options, while RFC2833 or SIP INFO may be used for DTMF signalling. The project should test call setup, speaker level, microphone level, echo, unanswered calls, forwarding, remote release and behaviour after a network interruption. Security settings should also follow the organisation’s policy, including strong administration credentials, protected management access, appropriate network segmentation and controlled remote connectivity.
This deep integration is one reason the unit suits organisations already using SIP phones. It can avoid installing a separate analogue intercom handset at every answering point. However, the benefit only appears when the call plan matches the business process. FourTeck can help buyers identify the receiving endpoints and questions that must be answered before the technical team configures the final solution.
Grandstream GDS3705 RFID, Keypad and Door Control
The built-in 125 kHz EM4100 reader provides a practical credential method for regular users. Employees, residents or approved contractors can present a compatible RFID card or key fob instead of waiting for an intercom answer. The platform recommends support for up to 2,000 credentials, giving small and mid-sized organisations room to maintain a useful card database. Before ordering cards in volume, the buyer should confirm that the existing credentials use the same technology. A card’s appearance does not prove reader compatibility, and newer NFC or smart-card formats are not automatically interchangeable with 125 kHz EM4100.
The metal keypad provides another entry path. PINs can be useful for selected users, temporary access or situations where carrying a card is inconvenient. They can also create risk when codes are shared, observed or left active after a contractor finishes work. The organisation should define code length, assignment, expiry, change frequency and administrator ownership. Shared permanent PINs may be simple to operate, but individual credentials provide clearer control when user accountability matters.
Two relay outputs allow the station to signal an electric lock, light or another suitable device within the published electrical limits. Two optocoupler inputs can receive low-voltage information from a door sensor or related equipment. RS485 and 26-bit Wiegand input/output interfaces provide options for integration with external access hardware. These features expand design flexibility, yet they do not remove the need for correct electrical planning. The electric lock may require its own power supply, isolation relay, surge protection or fire-alarm interface. A qualified installer must confirm fail-safe or fail-secure operation, emergency egress and local building requirements.
The best access workflow usually combines convenience with supervision. Staff may use cards, selected service users may have time-limited PINs and visitors may call reception. FourTeck can help the buyer translate these user groups into credential quantities, accessory requirements and quotation notes so the procurement package reflects the daily operating process.
Grandstream GDS3705 Rugged PoE Deployment and Management
Entrance equipment is exposed to conditions that ordinary office electronics do not face. Rain, dust, temperature changes, direct sunlight, public contact and attempted damage all influence the installation. The GDS3705 uses a zinc-alloy metal enclosure with IP66 weather protection and IK09 vandal resistance. These ratings support outdoor and public-facing use, but they apply to the device as tested and do not guarantee the completed installation. Cable entries, wall openings, junction points, connectors and power accessories still need suitable sealing and protection.
Integrated IEEE 802.3af Class 3 PoE can simplify cabling by carrying power and data through the Ethernet connection. This is helpful when a business already has a managed PoE switch and wants the door station on the same protected network as its voice endpoints. The designer should confirm available wattage, cable distance, copper quality, surge risk and backup power. A UPS supporting the switch can keep the door station and network running during a short outage, but the lock power supply and receiving PBX or phones must also remain available for the complete workflow to continue.
Management is supported through Grandstream GDS Manager and device administration tools. Centralised credential handling can reduce the effort of adding and removing cardholders compared with configuring each entry manually. The responsible team should maintain device names, IP addresses, firmware records, administrator roles, configuration backups and a documented process for revoking access. Remote management should be protected through the organisation’s network controls rather than exposed casually to the public internet.
Mounting choice also affects appearance and serviceability. Surface installation can reduce wall preparation, while in-wall mounting can create a cleaner finish when the wall structure and installation kit allow it. The installer should verify dimensions, cable bend space, drainage, canopy, visitor reach and future access for maintenance. FourTeck can help the buyer identify product and accessory needs; the qualified installer remains responsible for site preparation and commissioning.
What Buyers Should Check Before Purchase
Before requesting a quote, buyers should confirm the complete access requirement rather than selecting only by model name or headline feature. The GDS3705 is an audio-only SIP door station with 125 kHz RFID and keypad access. It can be an excellent fit for the right entrance, but a project that needs built-in video, NFC, Bluetooth, QR credentials or a newer management platform may require another model. A clear requirement prevents missing accessories, unsuitable credentials and expensive installation changes.
Configuration Fit
State whether the entrance needs audio only, RFID, PIN, remote release, door sensing or external-controller integration. Include user count, visitor volume and future expansion.
Compatibility Check
Provide the PBX, phone models, switch, credential technology, lock details and any Wiegand or RS485 controller. Request written confirmation for critical integrations.
Installation Environment
Share wall material, door type, sun and rain exposure, cable route, mounting preference, nearby power, public reach and photographs of the proposed location.
Accessories and Power
List cards, fobs, mounting parts, PoE injector or switch, lock power supply, exit button, door sensor, surge protection and spare units required.
Availability and Warranty
Ask for current supplier status, exact included items, delivery estimate, warranty terms, return procedure and the support path for the destination country.
Quote Preparation
Provide quantity, delivery location, target date, receiving endpoint, lock information, installation scope and whether the order is for one site or a phased project.
Long-term operating cost is not limited to the door station. Consider credential replacement, administrator time, network and PoE capacity, lock power, backup power, installation, firmware maintenance and possible spare units. A low-cost device can become expensive when the wrong card technology is ordered or the existing lock requires unexpected electrical work. Conversely, a well-matched audio station can be more economical than a video model when separate CCTV already provides visual coverage.
For replacement projects, send the current model, wiring diagram, mounting dimensions, card type, PBX details and reason for replacement. For bulk or project supply, add a site list, door count, standard accessory bundle and rollout schedule. FourTeck can use this information to review the requested unit, identify suitable alternatives and prepare a clearer commercial proposal.
Africa Availability and Service Support
FourTeck supports Grandstream facility-access inquiries across Africa with assistance for model confirmation, accessory selection, quotation preparation, delivery coordination and warranty guidance. Availability can change according to supplier status, exact model, quantity, destination, firmware region and project timing. The commercial offer should therefore identify the GDS3705, included RFID credentials or accessories, mounting components, power options and any related products individually rather than describing the order only as a door system.
Support begins with requirement review. Buyers can provide the number of entrances, user population, preferred entry method, existing PBX and phones, PoE switch details, lock type, sensor requirement, mounting environment and installation responsibility. FourTeck can help identify questions that require confirmation and discuss whether the audio-only model is appropriate. When a camera or modern mobile credential workflow is essential, the team can guide the buyer toward another suitable GDS option instead of forcing the original request.
Delivery coordination depends on the country, consignee details, shipment size, customs process and whether the order includes third-party locks, power supplies or installation materials. Project buyers should share target dates early, particularly when deployment covers several sites or needs phased delivery. Warranty coverage and handling are based on the selected supply route and written order terms, so these details should be reviewed before approval. Installation, configuration and commissioning can be discussed separately where available and should be scoped clearly.
Africa Country and Regional Coverage
Businesses, property managers, integrators and project teams across Africa, including Kenya, Uganda, Nigeria, Ghana, Tanzania, Rwanda, Ethiopia, South Africa, Zambia, Botswana, Senegal and nearby markets, can contact FourTeck for product availability, model guidance, accessory review and quotation assistance. Enquiries may cover a single office entrance, a residential property, a school, a clinic, a warehouse, a hospitality site or a multi-branch access project.
Regional requirements differ. An exposed coastal entrance may need careful corrosion and weather planning. A remote branch may require stronger surge protection and backup power. A large property may need consistent card administration across many doors, while a small office may only need one station linked to reception. Shipping routes, customs documents, installer availability and warranty handling can also vary by destination. FourTeck reviews these practical conditions during the buying discussion rather than assuming that one standard bundle suits every location.
Procurement teams managing several countries can improve consistency by defining an approved baseline: door-station model, credential type, PBX method, PoE standard, mounting approach, spare policy and documentation format. Individual sites can then adapt the lock hardware and installation details to local conditions. Visit the Grandstream GDS facility access series page for a wider family overview or use the Africa sales contact page to share the project list.
GCC, Middle East and Africa Availability
FourTeck Africa can support product inquiries for African organisations while guiding wider regional procurement conversations through relevant FourTeck platforms serving GCC and Middle East markets. Companies with operations in the UAE, Saudi Arabia, Qatar, Oman, Bahrain and African locations may want a consistent entrance standard, yet the commercial and installation route can differ between countries.
A regional access project should define a common technical baseline before equipment is ordered. This can include approved door-station models, card technology, PIN policy, SIP call routing, network segmentation, PoE source, lock interface, administrator roles, firmware approach, spare quantity and documentation. Each site can then adapt the baseline for local door hardware, building rules, weather exposure, shipping and installer responsibility. This method is more dependable than purchasing identical boxes without confirming how they will be powered, mounted and managed.
Availability, delivery options, tax treatment, warranty handling and configuration support vary by country, supplier and quantity. The quotation should clearly state the supplying entity, final destination, currency, shipment terms, included accessories and support scope. Regional buyers may review FourTeck Africa, FourTeck Kenya, FourTeck Uganda or FourTeck UAE according to the purchasing and delivery route.
For a cross-border rollout, share the country list, door quantities, required dates, invoicing location and local installation ownership. FourTeck can then help structure the conversation around a coordinated product list while recognising the conditions of each destination.
Other Options Buyers May Consider
A complete entrance solution may require another door-station model, a receiving endpoint, managed PoE switching or deployment support. The options below help buyers compare requirements without making an unfair one-model-fits-all claim.
Grandstream GDS3710
Consider this established video option when the entrance needs integrated visual verification, hemispheric coverage, RFID and SIP video communication in addition to door access.
Grandstream GDS3702
Review this audio intercom alternative when the project needs SIP voice, PoE and door-control connectivity but does not require the integrated RFID reader found on the GDS3705.
Grandstream GSC3570 Control Station
A dedicated touch control endpoint can suit reception, security or facility teams that need an organised interface for compatible Grandstream intercom and access workflows.
Grandstream GWN7800 PoE Switching
A managed PoE switch may provide network power, VLAN control and connectivity for door stations, IP phones and other business endpoints. Port count and power budget must be sized correctly.
Grandstream Network Installation Support
Projects that require VLAN, PoE, switch-port and cabling preparation can discuss deployment planning so the entrance device connects to a stable, documented network.
The correct alternative depends on the missing requirement. Choose video when visual confirmation is essential, a newer smart model when mobile credentials are central, or another audio model when the RFID reader is unnecessary. A receiving phone or control station should be selected according to the call workflow, while the network switch should be sized according to the total number of PoE devices and future expansion. FourTeck can help combine these items into one structured request.
Why Buyers Choose FourTeck
Facility access sits at the meeting point of networking, voice communications, electrical door hardware, physical security and daily building operations. A buyer may know the preferred model but still need to confirm whether the cards are compatible, the switch has enough PoE power, the PBX can receive calls, the lock circuit is suitable and the mounting accessories are complete. FourTeck approaches the request as a business requirement rather than a box-only purchase.
Assistance for offices, properties, integrators, branch rollouts and project quantities.
Review of audio needs, credentials, endpoints, PoE, lock interfaces and accessories.
A clearer bill of materials for door stations, cards, power, mounting and related equipment.
Pre-sales questions covering PBX, phones, network, credentials, controllers and door hardware.
Support for destination, quantity, phased supply and accessory consolidation.
Clarification based on selected product source, destination and commercial terms.
FourTeck does not replace the qualified installer responsible for lock wiring, egress safety, mounting, cabling and local compliance. Instead, the team helps procurement and technical stakeholders reach installation with a more complete product choice and clearer commercial scope. This can reduce delays caused by omitted cards, unsupported phones, inadequate PoE, missing power supplies or unsuitable mounting plans.
The same approach applies when the requested model is not the best fit. FourTeck can discuss a suitable alternative based on audio or video need, credential method, user volume, environmental conditions and delivery requirements. Buyers receive a practical route to quotation without unverified claims about stock, delivery speed or partnership status.
Frequently Asked Questions
What is the GDS3705 used for?
It is used as an IP audio intercom and controlled-entry endpoint. Visitors can call a compatible SIP phone or PBX destination, while authorised users may enter with a compatible 125 kHz RFID credential or assigned keypad code. Relay and input connections allow the unit to participate in a properly designed electric-lock and door-sensor installation.
Does the GDS3705 include a camera?
No. It is an audio-only door station. This can suit sites that already use a separate CCTV camera, do not require visual verification at the intercom, or want a focused voice-and-access solution. Buyers who need integrated video, wider visual coverage or video calling should review another Grandstream GDS model before ordering.
Can it call our existing IP phones?
The station supports SIP calling and broad interoperability, but the exact PBX, phone, codec, DTMF and remote-release workflow should be tested. Provide the receiving phone and PBX models during quotation. The technical team should verify registration, call routing, schedules, audio quality and the command used to trigger the configured door relay.
Which RFID cards are compatible?
The built-in reader uses EM4100 125 kHz credentials. Do not assume that an existing card is compatible because it looks similar. Card frequency and technology must be confirmed before bulk purchase. Buyers should also define who will enrol, issue, replace and revoke credentials and whether the recommended capacity suits the expected user population.
Can PoE power the door lock as well?
PoE powers the door station through its network connection. The electric lock commonly requires a separate, correctly rated power source and may need an isolation relay, emergency release and fire-system integration. A qualified installer must confirm the lock voltage, current, fail-safe or fail-secure behaviour and the complete life-safety circuit before installation.
Is the unit suitable for outdoor entrances?
The published design includes IP66 weather protection, IK09 vandal resistance and an operating temperature range from -30°C to 60°C. Outdoor suitability still depends on correct mounting, sealed cable entry, suitable surge protection, direct-sun conditions and the completed installation. An installer should assess the wall, canopy, drainage and exposure before commissioning.
Can FourTeck help choose the complete accessory list?
Yes. FourTeck can review the requested card quantity, mounting method, PoE source, lock power, exit button, door sensor, receiving phone, PBX environment and project spares. Final electrical and mechanical components must be approved by the installer, but the pre-sales review helps identify items that should appear in the quotation.
Is the GDS3705 available for Africa projects?
FourTeck supports inquiries across Africa. Current availability depends on supplier status, quantity, selected accessories, destination and project timing. Buyers should provide the delivery country, required units, target date and installation scope so the team can confirm the current supply route, commercial terms, delivery guidance and warranty handling.
How do I request an accurate quote?
Send the quantity, country, door type, lock details, RFID card count, keypad requirement, PBX or phone model, PoE source, mounting preference and required date. Mention whether you need equipment only or installation and configuration support. A complete request helps FourTeck prepare a clearer proposal and recommend alternatives where necessary.
