Question regarding Camera(PTZ) and higher voltage

[dnfakrnl 0]

I have installed 4 PTZ camera at a 76 gas station.

 

4 PTZ are all outdoor and I tried my best to shorten the distance between the cameras and its power.

 

However, 2 out of 4 is still not functioning to the fullest.

2 PTZ cameras that are working are getting 11.5v and 11.7v.

Other two that aren't working so hot is getting 11.0v~11.1v and 10.8v~10.9v.

I haven't checked the camera that gets 11.0v~11.1v if it is functioning well because it's always on the bright side, so the infrared was never on to check.

 

So my guess is these PTZ camera will fully function when it''s above 11.3v+

 

During the day time, everything is perfect. Even the presets, sequence, motion tracking, everything works completely fine.

 

So my idea since I can't shorten the wire anymore, I will try to get a power supply and increase the voltage. I had 2 existing power supplies and they supply 13.8v and 14.2v.

 

Now I'm hesitating to try this. Will this kill the camera? What usually happens when a camera is getting more than 1.0v~2.0v?

 

Thanks for the answers in advance!

Please let us know what type and size of wires you are using and the approximate distance between the PTZ and the power supply.

Please let us know what type and size of wires you are using and the approximate distance between the PTZ and the power supply.

 

I've used RG-59, the distance between the power and camera should be 80-100 ft.

 

Two of the camera that's working properly are around 30-40 ft. These cameras are getting 11.4v and 11.7v

 

These two camera work perfectly fine even with infrared.

 

The distance between the power and the PTZ used to be 200ft but I was not getting sufficient voltage at all, around 8v-10v so I cut down all the wires and installed power supply as closest to the camera as I can.

 

So if this 14.2v power supply plan doesn't work, for example, if its too risky for cameras to get higher than certain voltage, that means I'm gonna have to set up another power supply box outdoor in the open, which the owner doesn't prefer.

 

I will try to explain every details if I was asked.

 

Thanks for the reply

I answered a question similar to your problems. Here is the link viewtopic.php?f=6&t=49356

 

I am hoping you are using a good quality RG-59 with 18/2 or 16/2 power wires. Avoid using a premade undersize china made they claimed as Siamese RG-59.

 

I included all the links where you can buy them.

 

Good Luck & Happy New Year
