PTZ issue.......

I just went to a property I just purchased that is 5 hours away for a few-day trip to install security cameras. One of the cameras I brought was a DH-SD49225T-HN PTZ that was working 100% (I had taken it off my house). After getting everything installed, the PTZ was not working; it seems it was not getting enough power even though the TP-Link TL-SF1008P switch has a power budget of 60 watts—30 watts per port—and the only other camera on that port (I even unplugged it temporarily just in case) only consumes less than 15 watts. The PTZ was definitely getting some power but not enough to do the startup calibration (though it was trying). I tried the ports directly on the NVR also, which have a budget of 25 watts per port, and the same thing happened.


Things I took note of:

The cable length did not exceed 100 ft.

The cable was solid copper, not copper-clad.

Tested with two switches (the built-in NVR and the TP-Link), no change.

The other camera is and was working fine on the same cable run and on both NVR ports and the TP-Link switch.

Reterminated cable ends just to be sure

EDIT: I also plugged the PTZ directly to both the switch and NVR with a short cat 5 cable ... —same results...


I'm kind of stumped at this point and hoping someone with a fresh mind will have some suggestions!

Looks like you spoke to many of the cable concerns that come up, except troubleshooting the run itself. Not sure where the PTZ is mounted... can you bring an extension cord (and the PoE switch) with a short patch cable and see if the cam boots?? Or take the cam down and test on the bench.

Thanks spaceman! I forgot to add this "EDIT: I also plugged the PTZ directly to both the switch and NVR with a short cat 5 cable ... —same results..."
 
I would double check your cables? First when you take a camera that was working from 1 place and plug into another knowing that the switch is POE+ and the camera is lower end of the POE+ power demands and the camera don't work then first thing is Opps did you just connect to CCA cables.. Because high power POE or even POE+ powered PTZ will die most times in short order when you connect it with CCA cables..

How can you tell, Well connect the cable from the Camera to the Router or a non powered ethernet port and connect a 12v 3amp power supply or more. Like if you had a 5amp that is fine but needs to be 3amp or better.. Test it with power supply at the camera location and if you get the camera to post using 12v then the PD chip for POE is dead or some other part of the circuit.. I don't mean just doing the PTZ dance as 12v to camera will make the camera do the dance but getting a feed of the camera is what is important.. If there is no post and or no dance then camera is in need of deep repair.. If post, with 12v but not POE+ then would need to board level trouble shoot the PD for the POE circuit.

Looney2ns I can't believe I didn't catch that! I was looking at the Amazon description here because that's where I bought it from.

Apparently they have two different versions with the same model number! I must have used the Poe+ version on another job and thought that the one I grabbed for my house was the exact same thing minus the switches on the front.

Not sure the gauge. It's ubiquity tough cable, outdoor cat5

I try to keep a couple of high power poe injectors for cam's that need poe++ Some use the white blu/White brn prs for power to the camera. Can seem complicated but if tou have checked your cable, and seems you have, I might try a high power 60 watt poe injector.

Mine also came with a 60 watt 24v AC power supply. You'd have to run a separate pr if you used the 24v ac supply that came with mine.

I'm going to have to grab some of those to keep on me as well. That could have saved me a whole day of headache!

Anyways, I ordered a Poe plus switch. As this place is 5 hours away, I will see if my maintenance man can install it. Should be there on Tuesday (crosses fingers)..
