Hi

I recently got my first PTZ camera from Empiretech and the model is ptz4k-25x-pv.

My problem is that when i have the AI tracking function on ( IVS ) the camera randomly crashes/reboots for some reason, atleast 2-3 times aday.
It feels like when something fast is moving and the camera tries to track it.

I have the camera plugged in to my Ubiquiti dream router which should be able to handle the PoE power needed for the camera.

Does anyone else experienced same kind of problem when a PTZ camera is powered with PoE.
I have tried look in the Log for the camera but that doesn't tell me much to troubleshoot this problem.
 
Some of the ubiquity gear is proprietary power and are problematic for cameras other than theirs.

I do not know if yours is one of those or not, but I would try ail different power source.

Did you do a factory reset when you first got it? Many have found that helps a lot with the newer GUI.

Today i got myself a PoE+ injector for the camera so now time will tell if this solves my problem :)
I have not Factory reset the camera, the GUI looks pretty new to me and i also did a firmware upgrade yesterday.

That PTZ requires POE+, will not run properly on just POE. You run the risk of burning something up by doing so.

Thanks for reply, bought a PoE+ injector today before i upgrade my switch to a PoE+ :)

For a firmware update, best practice is to:

Factory reset
Apply firmware
Factory reset 3 times

People that can get "under the hood" have seen that sometimes all the firmware doesn't take with a simple flash and several factory resets clear it up.

Doesn't mean you won't have an issue, but best practice, especially for a PTZ, is the factory reset process.

Ok! I have nothing to lose to try it out since i don't have any specific settings stored yet
 
Now when the camera is installed at its correct location i get reboot problems even with my new PoE+ injector.
I got about 25meters (82 foot) of cable (23 awg solid bare copper) cable link

The camera spec say
12 VDC, 3 A ± 10%;
PoE+ (802.3at)
which is 36w at 12 volt.

And if i look at the table for power transmission of cables i could only run like 14 foot (4meters) with 12 volt.
But if i look at the table for 48 volt i could run up to 465 foot

The PoE+ injector i have is the unifi 30W PoE+ Adapter (30W)
The spec say
48V DC @ 0.65A

But i don't understand, does the camera handle 48 volt or how does it work?
And does this mean i'm about 6 watt short because of the camera needs 36 watt??
Or is it that the PoE+ injector downgrade the voltage to 12volt and i'm to far away with the cable so i can just simply move the PoE injector closer to the camera which i don't really wanna do....

Sorry for bad english but i think you guys understand my problem :)
 
After a bit of research it seems like the Unifi injector is a PoE 802.3at type 1 since it only have 48 volt out. And the camera needs PoE+ 802.3at type 2 which is 50-57 volt range. I'm correct?

Well, at first i had the camera running of a Unifi 802.3af injector that only supplied 15w... then i got the 30watt model which is a 802.3at but just at 48 volt.
So by the specs at the camera that say 802.3at that 30w unifi should work theoretically on paper.

And the camera doesn't reboot as often as before so it was a improvement for sure but i still get maybe 1 reboot once a day when the camera tracks something.
But due to losses in the cable my ptz camera maybe doesn't get what it needs to run 100% perfect.
So that is why i need a bigger PoE++ injector that can supply higher wattage.

Everyday we learn something new :D

Just use this one for most ptz camera from us.

Thanks Andy but i really need it before Friday so i'm ordering one from sweden and i'm looking at a (Zyxel PoE12-60W: Complies with IEEE 802.3btPoE++ 60 W standard) which should do the job 100% perfect :)

Cool, that is great, IVS tracking make the booting, normally because of poor power. Most PTZ need real POE+, so better use PFT1200 or use standard POE switch, the market have lots of cheap and poor quality injector.
