Proven to Power PTZ Cameras at Full Draw, Full Distance.

INDEPENDENTLY TESTED. ZERO FAULTS.

The Comnet CNGE10FX2TX8MSBT PoE switch and PS-A48500 48V Power Supply ran for over a month powering a PoE pan-tilt-zoom camera at maximum cable length and full IR output — with zero faults, zero disconnections, and stable power delivery throughout.

No Lab Shortcuts. A Full Month at Maximum Load.

TESTED UNDER REAL-WORLD CONDITIONS

Independent test engineers connected a Redvision CCTV X4 Commander PoE PTZ camera to a Comnet CNGE10FX2TX8MSBT switch over 100 meters of Cat5e cable. (The maximum run length allowed under IEEE 802.3). The switch was powered by a Comnet PS-A48500 48V PSU.

The camera ran a continuous tour pattern with its IR illuminators locked at full output for the entire test, the highest power draw the camera can produce, to see what happens when a PoE deployment is pushed to its real-world limit, not just its rated spec sheet.

The test was originally planned for one week. It ran for more than a month instead, because the results held up long enough to prove the point on their own: no truck roll to reset a dropped switch, no re-terminating a marginal run, no swapping a PSU that couldn't keep up.

Measured at the camera end of the run: 49.51V, 0.81A, 40.0W — IEEE 802.3bt Type 4, Mode A+B, holding steady for the full test duration.

What a Month of Zero Faults Actually Means for Your Install.

Full 100m Reach, No Compromise

Rated performance held at the maximum IEEE 802.3 cable distance — not a shortened test run. Integrators can spec full-length runs with confidence.

Full IEEE 802.3bt Power, Sustained

40.0W delivered continuously at 49.51V and 0.81A (Type 4, Mode A+B) with power draw held at the camera's absolute maximum (tour pattern, IR at 100%) for the full test.

Zero Faults, Zero Disconnections

No resets, no drops, no degradation over the entire test period. The switch and PSU didn't just survive the month, they didn't need to be touched.

Verified by an Independent Third Party

This wasn't a Comnet lab test. The camera manufacturer ran it, authorized it, and put its own engineering sign-off behind the result.

Built for the Installs Where Failure Isn't an Option.

PTZ cameras at full cable length and full IR draw are one of the hardest loads a PoE network carries. These are the deployments that put that load on the network every night.

Security & Surveillance

Long perimeter and parking-lot runs where PTZ cameras rely on IR illumination after dark, exactly the load profile this test ran continuously for a month.

Government & Campus

Multi-building sites where cable runs regularly approach the 100m IEEE 802.3 limit and downtime means a truck roll across the property.

Critical Infrastructure

Sites where a dropped camera feed isn't just an inconvenience, it's a compliance and safety gap.

Smart City & Intelligent Transportation

Traffic and public-safety camera networks where PTZ units run tour patterns around the clock, day after day.

Tested by the People Who Build the Camera, Not Just the Switch.

Independently Run and Authorized

Testing was conducted and formally authorized by the camera manufacturer's own Engineering Director.

Extended Beyond Its Original Scope

Planned as a one-week check, the test was extended to a full month specifically to validate long-term reliability, the engineers kept it running because it kept passing.

Measured, Not Assumed

Power delivery was independently monitored throughout with a dedicated PoE tester, not inferred from spec sheets.

Formal Recommendation to Approve

The test concluded with a documented recommendation approving the Comnet switch and PSU for use in PoE camera installations.

Rated on the Spec Sheet. Proven in the Field.

A month of continuous operation at full cable length and full power draw, with zero faults, verified by an independent third party. That's what's behind every CNGE10FX2TX8MSBT switch and PS-A48500 PSU that ships.
