Use a pre-quotation survey to determine whether the existing 2-wire route can support the selected IP intercom configuration. Record bus condition, topology, gateway location, available power, indoor monitor type and acceptance tests before replacement work.
The system uses an IP gateway to bridge an existing low-voltage route to the IP network when the survey confirms compatibility. Reuse of cable, conduit and wall finish is a project outcome to verify—not a blanket installation claim.
Record cable type, route length, topology and measured bus voltage. Use the wiring checklist during the site survey.
Replace the entrance panel and install the gateway in the communications cabinet. Confirm bus terminals, Ethernet uplink and PoE budget.
Replace apartment handsets after the backbox, cable termination and power conditions are checked. Unit time varies with access and wall condition.
Register endpoints, configure SIP or cloud services, then run call, video, unlock and handover tests against the approved checklist.
When the existing bus is compatible, the gateway can carry power and data over the retained route. Confirm load, voltage drop, polarity and floor distribution before the final BOM.
The adapter can be evaluated against common cable types found in European, GCC and Asian apartment buildings. Cable reuse is subject to measured voltage, cross-section, topology and gateway limits.
The adapter replaces the legacy endpoints; the existing cable may be retained after survey. The listed brands are common systems for review, not a blanket connection guarantee.
Use this model to frame the work packages for a 180-unit building in Germany or the UK. Obtain a project-specific BOM and local installation quotation before comparing options.
* No public price is shown. Confirm the bill of materials, local labour, access arrangements and scope in a written project quotation. Funding eligibility must be checked separately under the active programme rules.
Funding programmes and eligibility rules change. Treat this section as a documentation checklist; confirm the active programme, eligible measures and application sequence with the property owner or accredited consultant before work begins.
Request the document scope needed for the selected model, configuration and active programme. No document is represented as available until the review is complete.
Send the building size, existing wiring type, market and available survey data. We will return the reviewed reuse boundary, selected configuration and written commercial scope. Standard supply starts at 200 units; OEM/private-label at 500; ODM at 1,000.
Possibly. Existing 2-wire bus, 4-wire analog or CAT3 routes can be considered when measured voltage, topology, cable condition and gateway limits are suitable. The survey identifies what can be reused and what must be replaced; the selected door station, gateway and monitors are then recorded in the project BOM.
A documentation package can be prepared for review, but eligibility, programme names, limits and application timing depend on the current German funding rules and the property. Confirm the active programme with the owner or accredited consultant before work begins.
The review covers 2-wire bus (0.5–1.5mm²), 4-wire analog cable, CAT3 or telephone cable, and CAT5e/CAT6 for a direct PoE path. Single-wire, coaxial and fibre routes are normally outside this configuration. Measure bus voltage, cross-section, topology and route length at the communications room before ordering.
A 180-unit reference sequence is 3–5 working days with a 2-person installation team, provided access, materials and the existing route meet the approved scope. The final schedule depends on resident access, backbox condition, floor topology, commissioning tests and local site rules.
EU-hosted cloud or on-premise NVR storage can be evaluated by deployment. Confirm the data region, retention period, controller/processor roles, DPA and resident-consent workflow before ordering.
Compare cable and conduit work, local labour, wall repair, resident access, hardware, gateway modules and commissioning. Confirm the project-specific BOM, local installation scope and written commercial terms after the survey; no public unit price is used.
The system is designed for SIP 2.0 (RFC 3261). A connection to Asterisk, 3CX or another PBX can be reviewed against the selected model and firmware. Confirm registration, codec, door-release, directory and server-policy requirements for the deployment.
A smart-lock 2-wire retrofit is not implied by reusing the legacy intercom bus. The survey must confirm the door hardware, power path, release interface and any gateway or controller needed for the selected lock. Record these separately from monitor replacement and video-call commissioning.
Review the existing cable, power, mounting condition, release path and user workflow. Separate reusable infrastructure from replacement items, then record the selected gateway, monitor, lock or controller configuration for commissioning and handover.
