Everything distributors, project teams and property developers need to evaluate and source IP video intercom systems at wholesale.
1. Connection path: SIP 2.0 vs. a documented route
The first decision when selecting a video intercom system is the connection path required by the project. SIP 2.0 is available on selected models; other routes must be reviewed against the named equipment and firmware.
| Dimension | Open SIP | Proprietary |
|---|---|---|
| Property-management / third-party connection | Confirm SIP 2.0 or documented interface per model | Connection scope must be reviewed |
| Indoor monitor choice | Confirm the selected monitor or endpoint | Confirm the selected vendor route |
| Cloud dependency | Confirm local or hosted server path | Confirm the selected service path |
| Long-term lock-in risk | Low — switch panels without rewiring | High — full system replacement needed |
| Commercial terms | Confirm by model and quantity | Confirm by model and quantity |
2. Cabling: PoE vs. 2-Wire
PoE (Power over Ethernet)
PoE panels receive both power and data over a single CAT5e/CAT6 cable. For new construction, this is the preferred option: no external power adapter, clean installation, and centralized management via PoE switches.
- Single CAT6 cable per panel — review the cable route and installation scope
- Supports 1080p video and fast-boot (<8 seconds)
- IEEE 802.3af/at standard — confirm the switch port and power budget for the selected model
2-Wire (Retrofit)
For buildings with existing analog intercom wiring, 2-wire IP adapters allow upgrading to modern IP/SIP panels without replacing the cable infrastructure. The adapter sits at the panel end and converts the 2-wire signal to PoE Ethernet.
- Preserves existing wiring investment — critical for retrofit bids
- Max cable run: typically 100–200m depending on wire gauge
- Suitable for buildings with 1990s–2010s analog Fermax, Aiphone, or Comelit systems
3. Video Standard: ONVIF & Resolution
Request an ONVIF connection review for the named NVR/VMS. Confirm the stream, codec, events and authentication on the selected model before recording the door-station camera alongside other IP cameras.
- Minimum specification for MDU: 2MP (1080p), WDR, IR night vision to 3m
- Premium specification: 2MP + face recognition, anti-spoofing (3D structured light)
- Weatherproofing: IP65 minimum for exterior panels; IP66 for coastal or high-humidity sites
- Operating temperature: −40°C to 70°C for Middle East and northern Europe coverage
4. Certifications for Your Target Market
| Market | Required Certification | Notes |
|---|---|---|
| European Union | CE (RED Directive 2014/53/EU) | Mandatory for all RF-emitting devices |
| United States | FCC Part 15B | Required for all electronic devices |
| UAE / Saudi Arabia | TDRA / CITC approval | Type approval per product SKU |
| Great Britain | CE or UKCA route | Confirm current product-specific marking, documentation and economic-operator requirements |
| All markets | RoHS 2.0, EN 60950 | Required for commercial importation |
5. MOQ and Commercial Planning
B2B pricing for IP video intercom systems varies by model, specification, accessories, testing, destination market and customization level. Use the following commercial programme structure for initial planning and request a written quotation.
| Quantity (Door Panels) | Standard PoE 1080p | Face Recognition | OEM Private Label |
|---|---|---|---|
| Standard supply | Starts at 200 units | Confirm by written quotation | Confirm by written quotation |
| OEM/private-label programme | Starts at 500 units | Confirm by written quotation | Confirm by written quotation |
| ODM scope | Starts at 1,000 units | Quoted after technical review | Quoted after technical review |
Indoor monitor selection and any mobile path are confirmed by model, quantity and project scope. Request a written quotation instead of using public unit-price assumptions.
6. Connection Checklist for Project Teams
- PBX connection: Asterisk, 3CX or another PBX can be reviewed against the selected SIP 2.0 model and firmware.
- Property-management connection: Confirm the documented interface and workflow required by the selected project.
- Access control: Review Wiegand 26/34 or OSDP v2 output with the named access controller
- NVR/VMS: ONVIF connection can be reviewed for recording door-camera footage on the named system
- Lift control: Dry-contact relay output for floor-by-floor elevator access (MDU requirement)
- Interface documentation: Request the model-specific API or event notes only when that connection is in scope
7. Key Questions to Ask Your Supplier
- Is the SIP firmware open-standard or does it require a proprietary server?
- Can you provide the DoC and accredited lab report for CE certification?
- What is the firmware update policy and how long is security patch support guaranteed?
- Is the mobile app white-labelable and published under our brand on App Store / Google Play?
- What is your warranty term and RMA process for defective units at scale?
- Do you offer technical pre-sales support and connection documentation in English?
Frequently Asked Questions: Video Intercom B2B Buyer Guide
Selected models provide SIP 2.0 connection capability. Confirm the required behavior with the named Asterisk, 3CX or other PBX, plus the device, firmware and project scope, rather than assuming every third-party workflow is supported.
Required documents depend on the destination market and exact hardware variant: request the applicable CE, UKCA, FCC, SASO/CST or TDRA documents and underlying test reports where relevant. If NVR/VMS connection is required, ask for the model-specific ONVIF connection evidence and test scope; a general catalogue statement does not prove the project connection. ISO 9001 describes the factory quality system and does not replace product-level documents.
For planning, use standard supply 200 units, OEM/private label 500 and ODM 1,000 Pricing depends on the model, configuration, accessories, testing, destination market and order volume; request an itemized quotation for each component.
A project team should verify SIP 2.0 connection against the named Asterisk, 3CX or other PBX, ONVIF connection against the intended NVR/VMS, door-release method and access-controller interface, two-way audio, PoE budget, operating temperature, IP rating and the document set for the exact model and firmware. Request a sample or bench test before volume supply; a catalogue statement does not prove a project connection.
Choose PoE when the building has Cat6 infrastructure or the project can provide a managed wired path. Choose 2-wire retrofit when existing bus wiring is serviceable and a new cable route would require disruptive work. For either path, confirm the named NVR/VMS, PBX and access-control connection by model and test the required workflow before approval.
Minimum specification for new installations: 2MP (1920×1080, 1080P) image sensor, H.264 or H.265 compression, wide-angle lens (100–120° horizontal FOV) for entrance coverage, IR night vision with effective range of 1–3 metres for after-dark visitor identification, and IP65 minimum for outdoor exposure. Higher specification for face recognition or evidence-quality recording: 5MP or 8MP sensor, WDR (Wide Dynamic Range) 120dB+ for backlit entrance scenarios where sunlight behind visitors causes underexposure, and H.265 compression to manage storage bandwidth. Avoid cameras with fixed-focus lenses for installations where visitors may approach from varying distances — varifocal lenses allow field adjustment after installation.
Seven questions every B2B buyer should ask: (1) Which model and firmware will be supplied? (2) Can SIP 2.0 connect to the named Asterisk, 3CX or other PBX, and which call or release actions were tested? (3) Can ONVIF connect to the named NVR/VMS, and which streams, events and authentication were accepted? (4) What test reports and destination documents identify the supplied hardware? (5) What is the firmware and support ownership? (6) What warranty and RMA process applies to the written scope? (7) What sample or reference evidence can be reviewed before volume supply?
