Comelit UT9172 Surface-Mounted Wall Housing for 2MP Ultra
Overview
The Comelit UT9172 is a surface-mounted wall housing engineered for Comelit Ultra series 2MP cameras. Unlike recessed installations that require cutting into walls, the UT9172 mounts directly to finished surfaces—useful when structural modification isn't an option or when you need to retrofit existing institutional spaces (offices, schools, retail). The housing integrates PoE+ power delivery at the mounting point, eliminating the need to run separate power cables to the camera location.
Key Features
- PoE+ (802.3at) Power Delivery: Draws power directly from your network infrastructure—no 12VDC injectors or AC outlets required at the wall. Simplifies rough-in when wiring runs are already in place and keeps the installation footprint minimal.
- Comelit Ultra 2MP Compatibility: Engineered specifically for Comelit's Ultra line. Housing and connector alignment are matched to the camera's form factor, ensuring a secure, flush fit without adapter plates or shimming.
- Surface-Mounted Form Factor: Mounts directly to drywall, plaster, or hard wall surfaces without recessed box cutouts. Useful for retrofit jobs, historic buildings, or any scenario where breaking into the wall is undesirable or prohibited.
- Indoor Institutional Rating: Designed for protected indoor environments—offices, school hallways, conference rooms, retail checkouts. Not rated for outdoor moisture, direct sunlight, or heavy dust; skip this if your deployment requires weatherproof sealing.
- Standard RJ-45 Connectivity: Uses industry-standard Ethernet cabling. Plug directly into any PoE-enabled network switch or injector; no proprietary connectors or vendor-specific infrastructure required.
- Enterprise-Grade PoE Compatibility: Works with any switch or injector delivering IEEE 802.3at PoE+ (30W available per port). No risk of power starvation if your switch is already supplying 802.3at to other devices on the same line.
Integration & Compatibility
The UT9172 pairs with any IP camera surveillance setup already using Comelit Ultra 2MP models. Since it passes standard Ethernet through to the camera, it works transparently with any NVR or VMS software that supports ONVIF or Comelit's proprietary protocol. If you're planning a multi-camera install, ensure your PoE switch has sufficient budget: each Comelit Ultra 2MP camera via this housing will draw typical power loads between 5–12W depending on lens motor activity and IR operation. A 48-port PoE+ switch can comfortably handle 10–15 of these cameras without exceeding per-port or total system power limits.
Deployment Considerations
Surface mounting is faster than recessed installation—no drywall repair, no inside-wall routing, no risk of hitting plumbing or electrical. However, the housing sits visibly on the wall; if aesthetics or discrete placement matter in your space, a recessed variant or a different mounting strategy may be better. Also confirm that your wall substrate is solid enough for secure mounting; drywall anchors work, but masonry or stud mounting is more robust for long-term reliability. Check local fire codes if the installation is in a critical or egress pathway; some jurisdictions require approved conduit or specific fastening methods for wall-mounted devices.
When to Choose a Different Model
If your site requires outdoor or semi-outdoor coverage, look for a weatherproof housing variant in the Comelit Ultra line with an IP66 or IP67 rating. If you're deploying high-resolution (4MP or 5MP) cameras, confirm that the UT9172 is certified for those models—this housing is specifically matched to 2MP Ultra cameras. For recessed ceiling or pendant mounting, consider Comelit's in-wall or fixture-mount alternatives.
Frequently Asked Questions
Q: Is the UT9172 compatible with non-Comelit Ultra cameras?
A: No. This housing is engineered for Comelit Ultra 2MP cameras only. Using it with other brands or models may result in misaligned connectors, poor seating, or damage to the camera's power pins.
Q: Do I need a separate PoE switch, or can I use an injector?
A: Either works. A PoE-enabled switch is cleaner for multi-camera deployments; an injector works fine for single or small clusters if your network segment doesn't already have PoE.
Q: Can the UT9172 be used outdoors?
A: No. This housing is rated for indoor institutional environments only. Direct rain, UV exposure, or extreme temperature swings will degrade seals and electrical connections. Use a weatherproof housing variant if you need outdoor coverage.
Q: What wall types can the UT9172 mount to?
A: Drywall, plaster, concrete, and wood stud. Use appropriate fasteners for each—drywall anchors for hollow cavities, concrete anchors for masonry, wood screws for studs. Avoid mounting on surfaces prone to vibration or movement.
Q: Does the UT9172 include mounting hardware?
A: Mounting template and fastener guidance are provided in the packaging. Specific screws, anchors, and wall plugs vary by substrate; verify your wall type before installation and source fasteners accordingly.
Q: What's the maximum cable run from the PoE switch to the UT9172?
A: Standard Ethernet limits apply: 100 meters (328 feet) per IEEE 802.3. Beyond that, use intermediate switches or fiber extenders.

The Comelit UT9172 solves a real problem in retrofit and institutional deployments: you have finished walls and you don't want to cut into them. Surface mounting the UT9172 is fast—anchor to drywall, plug Ethernet in, and your 2MP camera sits flush against the wall. PoE+ power is integrated at the housing, so you're not hunting for a 12VDC outlet or running separate power infrastructure.
Technical Highlights:
- PoE+ (802.3at) Integration: 30W available per port means headroom for the Comelit Ultra 2MP camera's motor zoom and IR operation. At typical 5–12W draw, a single PoE+ port can handle this housing without power negotiation delays or brownouts.
- Comelit Ultra 2MP Engineered Fit: Connector alignment and housing geometry are matched to the camera—no shimming, no adapter plates, no guessing about clearance. This level of OEM integration matters on large installs where consistency saves commissioning hours.
- Surface-Mount Form Factor: Eliminates drywall cutting, patching, and electrical conduit routing inside walls. On a 20-camera school hallway retrofit, this cuts installation labor by 30–40% compared to recessed boxes.
Deployment Considerations:
- Wall Substrate Matters: Drywall anchors work but aren't ideal for long-term 24/7 mounting in high-vibration areas (near HVAC returns, mechanical rooms). Stud or concrete mounting is more robust; plan fastening strategy during site survey.
- Indoor-Only Rating: No IP rating for weatherproofing. Humidity, temperature swings, or direct sun exposure will degrade seals and solder joints. If your deployment creeps into semi-outdoor spaces (covered porches, unheated storage), this housing will fail faster than a weatherproof variant.
- Visible on Finished Surface: Unlike recessed boxes, the UT9172 sits proud of the wall. If your client demands discrete placement or aesthetic blending, you'll need to discuss alternate mounting or accept that it will be visible to visitors and occupants.
The UT9172 is the right call for indoor institutional retrofits where speed and avoiding structural modification are priorities—schools, office parks, retail stores. If you're designing a greenfield building or dealing with outdoor/semi-outdoor exposure, choose a weatherproofed housing variant or a completely different mounting strategy.
