Red & White Wire - Where?

[Cheruki 0]

I need to re-install a camera but cannot remember how to wire the thing. I'm totally void of any knowlege regarding electricity, so don't laugh! My power cable has a red wire and a white wire and the camera has DC12V terminal on left, AC24V terminal in the middle and a F.G. terminal on the right. Also, when connecting power cable to the AC adapter, does it matter which wire goes where?

 

Adapter specs:

Plug In Class 2 Transformer

Input 120VAC 60Hz 35W

Output 24VAC 1.2 AMP

Plug 2.1x5.5MM

 

I was told that this adapter would power two of these cameras - is that correct? Thanks to anyone who can offer some help!

********It is possible this info could be incorect, dependant on hardware so I would test on a multimeter first********

 

But seeing as no one may help you due to not wanting to blow your cam up...here is what I think.

 

Your camera has a 24v option so it supports 12vdc and 24vac, and the power supply you are using is 24vac so it does not matter with polarity, you can plug any wire in (except to the 12vdc option)..so you can for instance plug Red into 24Vac and Black into FGround

Generally a 1.2 amp power supply should easily be able to power 2 cams with room to spare for more, but its impossible to say for certain, as we dont know what camera you are using, and how what its power requirements are.

 

It may have the power requirements written on the cam, (watts or ma required) or the info may be available if you search its model number on the net. In general though, it would have to be a beast of a camera to use more than 0.6 amp at 24v (unless you are also powering lights or heater or pan tilts etc, in which case you can easily find the psu is not up to it)

 

If the camera does not state its requirements, and you cant find the info anywhere, you can check how much power its using with a multimeter that measures current (not voltage, you need one that does current, not all do)

 

But in general, 2 standard cctv cams (with nothing extra hardware) should work of that psu easily.
