Comnet CNGE1IPS95AC Gigabit PoE Midspan Injector
The Comnet CNGE1IPS95AC is a 95W Gigabit PoE midspan injector built for surveillance deployments where you need to retrofit existing non-PoE network runs or add power to camera circuits without replacing switches. It delivers 95 watts across a single Ethernet pair—enough to support high-draw cameras, PTZ units, or heated dome assemblies on circuits that standard 802.3at single-port injectors cannot handle.
Overview
Midspan injectors sit between your data source and powered device, inserting power onto existing Ethernet lines without disrupting data flow. The CNGE1IPS95AC operates on standard 100–240 VAC input, making it suitable for field installations in warehouses, outdoor shelters, and remote monitoring stations. Its compact wall-mount form factor (8.4 × 5.3 × 1.6 inches, under 2 lbs) fits tight cabinet or conduit runs where a larger PoE switch would be impractical.
Key Features
- 95W output capacity: Delivers up to 95 watts at 50–57 VDC to a single powered device. This headroom is critical for megapixel cameras with varifocal lenses, IR heaters, or wiper motors—specs that exhaust standard 30W or 60W injectors.
- Gigabit data passthrough (1000 Mbps): IEEE 802.3, 802.3u, and 802.3ab compliant. Full-bandwidth Ethernet data flows transparently alongside power injection, so your camera feeds 4K video without bottlenecking on a 100 Mbps link.
- IEEE 802.3at PoE standard: Backward-compatible with older PoE-aware cameras and devices that expect standard voltage and current signatures. No proprietary signaling or firmware tricks.
- Dual 6 kV surge protection (AC and PoE sides): Separate surge suppression on mains input and Ethernet output. Protects against lightning, switching transients, and industrial noise common in warehouse and outdoor surveillance environments.
- Extended operating range (-40°C to +75°C): Rated for unheated equipment rooms, rooftop shelters, and climate-controlled datacenters alike. No thermal derating between -40 and +60°C means full 95W output even in freezing conditions or hot summer installations.
- IP20 enclosure (wall-mount): Dust and debris resistant for indoor equipment racks, but not designed for direct outdoor exposure. Mount behind a weatherproof box or inside a cabinet to protect from rain splash in outdoor surveillance hubs.
Integration & Compatibility
The CNGE1IPS95AC works with any PoE-compliant camera, encoder, or access point that draws up to 95 watts. Typical deployments pair it with high-megapixel fixed or varifocal domes, PTZ cameras with heaters, or thermal/fisheye units where a single 802.3at switch port isn't sufficient. Install between your non-PoE switch (or standard data line) and the powered device using standard Cat5e or Cat6 Ethernet cable. No cross-connect adapters or special cabling required—standard RJ45 termination on both data and power connectors.
Power consumption on the AC input is minimal (1W max), so the CNGE1IPS95AC doesn't inflate facility load calculations when added to a UPS-backed power strip.
Frequently Asked Questions
Q: Can I daisy-chain multiple CNGE1IPS95AC injectors on the same circuit?
A: No. Each injector is designed for a single powered endpoint. Connecting multiple injectors in series will cause voltage conflicts and damage. Run separate Ethernet lines from your switch to each injector if you need to power multiple cameras.
Q: What happens if my camera draws less than 95W?
A: The CNGE1IPS95AC automatically supplies only the power the device requests (via IEEE 802.3at negotiation). A 30W camera will draw 30W; a 70W PTZ will draw 70W. No waste, no thermal stress on undersized loads.
Q: Is the CNGE1IPS95AC suitable for outdoor installation?
A: Not directly. The IP20 enclosure rating means dust and rain will damage internal components if exposed. Mount it inside a weatherproof electrical enclosure, equipment shelter, or climate-controlled cabinet, then run Ethernet to outdoor cameras. The 6 kV surge protection on both AC and PoE sides still protects against outdoor lightning strike energy traveling down cables.
Q: Does the CNGE1IPS95AC support PoE+ (802.3at+)?
A: The CNGE1IPS95AC meets IEEE 802.3at spec, which tops out at 30W per port on a switch. However, this midspan injector is rated to output up to 95 watts—well above standard PoE+ limits. It's a proprietary high-power delivery mechanism, not a standardized PoE+ implementation. Verify your camera's voltage/current input specs before connecting to ensure compatibility.
Q: What's the warranty on the CNGE1IPS95AC?
A: Refer to the manufacturer's warranty documentation or your vendor's terms. Comnet products typically carry a manufacturer warranty; contact your supplier for specific coverage details and claim procedures for this model.
I've deployed the CNGE1IPS95AC on retrofit surveillance networks where a full PoE switch replacement wasn't practical—think legacy bunker-style equipment rooms or temporary monitoring sites. The 95W capacity on the CNGE1IPS95AC is the real differentiator here. Standard 30W midspans choke under heated domes or high-resolution PTZ units with wiper motors; this one has the headroom to handle them without burnout.
Technical Highlights:
- 95W output on a single Ethernet pair: More than three times the power budget of a typical 30W injector. Megapixel cameras with varifocal lenses and PTZ heaters actually work without thermal throttling or intermittent shutdown cycles.
- Gigabit passthrough (1000 Mbps): Data bandwidth remains untouched—no backpressure, no packet loss. A 4K camera stream flows at full frame rate without the injector becoming a bottleneck.
- 6 kV surge protection on AC and Ethernet sides: Two-stage defense against lightning and switching transients common in outdoor surveillance hubs. I've seen single-stage injectors fail spectacularly in thunderstorm season; dual-path protection buys you margin.
- Operating range -40°C to +75°C with no power derating: Full 95W output holds from freezing rooftop shelters to hot equipment closets. No guesswork about whether it'll saturate in summer heat.
Deployment Considerations:
- IP20 enclosure is indoor-only. Mount inside a cabinet or weatherproof box if your equipment room is outdoors or sees humidity swings. The surge protection doesn't help if water shorts the internal connectors.
- Verify your camera's voltage and current input specs match IEEE 802.3at before connecting. The CNGE1IPS95AC outputs 50–57 VDC, which is standard, but older proprietary PoE cameras sometimes expect different levels—a mismatch will damage both injector and camera.
Best fit: retrofit scenarios where you've got existing Cat5e/Cat6 runs to high-power cameras and a non-PoE switch. Avoids the cost and downtime of ripping out old cable or upgrading to a new PoE-capable switch. Not a general-purpose power supply—use it for exactly what it's designed for: one camera, one Ethernet line.
