PTZ Wiring help

[guyinberkshire 0]

Hi Guys

 

I fit basic cctv systems as a hobby to earn a little extra cash on evening and weekends.

 

I recently have been asked to set up a PTZ camera for a neighbour, however I have never wired one of these before.

 

I have attached a picture of the connector I have. Bare in mind I have no power supply for this as well.

 

Could someone advise me on the following

 

What power supply would this take

 

Why are there 2 cables coming out of each of the red connector block (4 in total) (Which I assume is 24v)

 

So it has a coax output for video, so I can only assume that both control and power goes through the red connector block, but how?

 

The black cable that plugs into the board goes to the camera itself.

 

Thanks in advance for your help.

I believe the black and red are for the power supply, which is 24v that you will need, and the blue and yellow are for the rs485 connection. Blue is typically A and yellow is B on the dvr. The camera manual should say for sure about that one.

 

You'll have to wait for confirmation from the guys who know for sure though.

The labelling on the unit is pretty clear: the red connector is for 24VAC power, the black connector for the serial connection. As to why there are two wires on each of the red terminals, I'd guess that's just done to double the current capacity, since that appears to be fairly small wire.

 

Id' say your power supply should be at least a 40VA rating, more if the PTZ has a heater/blower.

 

What's odd is the connection to the camera: a single pair to carry video, power and serial??

Sorry, I should have mentioned that on the left of that picture, a cable plugs into the back of it which goes to the camera, Its looks like a rj45 but I'm not sure as its only long enough that it stops half way in the metal frame of the camera. So had to disconnect it in order to take a picture.

 

I should say I am from the UK so there might be some slight differences in power. But it does have a small fan inside which I assume is a blower. I have a feeling that is what the black cable is.

 

Thanks for your advice so far

Ah, that makes sense. Well, hard to say without seeing the actual circuit boards, but yeah, it sounds like that cable is the main connection between this interface board and the camera, and the black wire would most likely be something power-related, whether general camera power or just for the fan.

Small fan is PROBABLY just a cooling fan, rather than something for circulating air to keep the dome clear. Either way, there should be no difference in the ratings you need to look for - you want a transformer that's 24VAC output, minimum 40VA output capacity. Only difference between you and someone in North America is that you'll be looking for something with a 240VAC input, rather than 120VAC.
