Hi Brandon,

PTZ (Pan-Tilt-Zoom) cameras sometimes require more than just 15.4 watts. What's the power requirement of your PTZ camera?

the product manual indicates 9.2W w/o a heater and 12W with a heater. i've connected the cameras to a 3750-48ps that i had in my spare inventory and they seem to be working on that switch. the issue now is, i don't have 3750's to replace all of the 3550's that i'm using to power these cameras.

Correct me if I'm wrong...but isnt the 3550-24PWR a Cisco pre-standard PoE switch. If thats the case, you will run into issues trying to power 802.1af devices.

starting with IOS 12.1(19)EA1c you have the ability to power 802.3af devices.

Is CDP enabled on the port of the PTZ?

What is the result when you do "sh power inline "?

it's a non-cisco camera, so CDP isn't going to help me.

i figured out the issue. the vendor installing the cameras pinched and damaged the cable when they installed the housing of the camera. i had to re-crimp a new RJ 45 on the cable and all was good. thanks for your responses.
