SIP 2.0 Video Intercom for MDU and Commercial Entry
Use the TD-D801 for MDU or commercial entrances that need a SIP 2.0 door panel. The PBX, ONVIF/NVR path, firmware, credentials and destination requirements must be checked against the proposed configuration before quotation.
Deployment Fit for MDU and Commercial Entry
Use SIP 2.0 when a door station must register to an existing PBX or share a call plan across multiple entrances. The PBX, network and lock interface set the final design.
SIP registration
Register the TD-D801 as a SIP endpoint on the named PBX. Verify transport, codecs, DTMF, authentication and door-release behaviour against the server configuration.
Unit and dial-plan capacity
System capacity is pending confirmation and is not listed in the current datasheet. Final capacity depends on the server, directory, entrance count and call-flow rules across towers, floors and mixed-use units.
PBX connection review
The TD-D801 can be reviewed for connection with Asterisk, 3CX or another PBX. Map the call flow to the target server and check licensing, mobile-answering and simultaneous-ringing rules before approval.
Power and network
The current datasheet lists a DC 12V supply; PoE is pending confirmation. Check the cable route, power source, port allocation, VLAN, firewall and local backup-power requirement in the site design.
Video recording path
The panel can be reviewed for an ONVIF connection with a named NVR/VMS. Confirm the required stream, codec and event set, then test discovery, authentication, video, audio and relay events on the target firmware.
Transport security
SIP over TLS and SRTP are conditional on the selected firmware and PBX. Define certificates, cipher policy, NAT handling and logging requirements before commissioning.
SIP 2.0 Deployment & Connection Checklist
Before quotation, record the items below against the selected model, firmware and target infrastructure.
SIP / PBX
Record SIP 2.0, transport, codecs, registration limits, DTMF and inbound/outbound call tests for Asterisk, 3CX or the named PBX.
ONVIF / RTSP
Record the ONVIF request, RTSP streams, firmware and target NVR/VMS. Test discovery, authentication, video, audio, events and door-release workflow.
PoE / VLAN
Check the DC 12V supply route (PoE pending confirmation), cable route, IP plan, firewall and NAT. VLAN deployment is possible when the site policy and switch configuration permit it.
OEM / ODM Handover
For standard supply, OEM/private label or ODM scope, request the model-specific datasheet, configuration guide, sample terms, change-control record, certifications and acceptance checklist.
Use the SIP and ONVIF selection guide for product choice, the multi-tenant planning guide for entrances and units, the ONVIF connection checklist for NVR/VMS testing and the video intercom projects FAQ for buyer questions.
PoE Video Intercom Supplier Review
Before requesting a PoE quote, record the power budget, cable route, entrance count, recording path and acceptance tests.
Switch or injector budget
Record the power source (DC 12V per datasheet; PoE pending confirmation), uplink plan and local backup power. Match the panel, switch and cable length to the same power assumptions.
Cat5e / Cat6 route
Map the entrance-to-network route, distance, patching, VLAN and firewall owner. Check the route against the site design and installation method.
MDU entrance count
Provide entrances, apartment extensions, indoor endpoints and simultaneous-call requirements. Map the bill of materials to the call plan and handover owner.
NVR / VMS and PBX path
Name the target PBX and NVR/VMS, streams, codecs, events and door-release actions. Check compatibility by model and firmware, then record the acceptance test.
Sample and commissioning
Use a sample to test call, audio, video, unlock, PoE recovery and any required ONVIF or PBX behaviour on the target network. Assign commissioning and first-line support.
Quotation checklist
Request the model, firmware, quantity, entrance count, accessories, documents, warranty, lead time and OEM or private-label scope in one written quote. Review the distributor route when channel support is part of the brief.
For wiring selection, compare the 2-wire and 4-wire video intercom routes. Request the applicable files from Downloads or submit the RFQ with the entrance count, network route and target PBX/NVR.

SIP 2.0 — Technical & Commercial Questions
The TD-D801 can be reviewed for connection with Asterisk, 3CX or another PBX. Verify registration, transport, codecs, DTMF, authentication and door-release behaviour on the named server and firmware before approval.
System capacity is pending confirmation and is not listed in the current TD-D801 datasheet. Final capacity depends on the server, directory, entrance count and call-flow requirements, so confirm it for the selected design before quotation.
The TD-D801 can be reviewed for an ONVIF connection with the named NVR or VMS. Confirm the model, firmware, stream, codec and event requirements, then test discovery, authentication, video, audio, events and relay behaviour.
Wiegand output is pending confirmation and is not listed in the current TD-D801 datasheet. Confirm the interface, card format, electrical level and cable limits for the shipping revision before installation.
Define the storage model, data region, retention period, controller/processor roles, DPA, resident notices or consent workflow and access logging. On-premise NVR and cloud designs have different responsibilities; record the selected model in the project documents.
The current TD-D801 datasheet lists a DC 12V supply with 550 mA operating and 290 mA standby current. PoE support and PoE class are pending confirmation; confirm the power route for the shipping revision before selecting a switch or injector.
Resident smartphone calling is possible when the selected SIP server and app support push delivery, live video and the approved door-release command. Confirm the app, network path and remote-release behaviour in the acceptance test; latency depends on the site and mobile networks.
SIP signalling does not certify a lock-control path.
A smart-lock SIP system needs more than call signalling: identify the receiving endpoint, authorisation source and approved command interface. Smart-lock SIP connection is confirmed only for the named intercom, lock, firmware and control route. The same rule applies to video-intercom SIP connection in a multi-door project. A video-intercom SIP system still requires a topology, account plan and acceptance test for the named devices.
