Need Help! DC 12V or AC 24V

[youngslick509 0]

sorry for my noobieness but im trying to connect 4 cameras a friend passed down to me, and im trying to set them up at my place, i pretty much have everything i need to have them up and running except for the power supply, which im unsure of which one they should run on, ive done a little research and i found out theres two types or atleast thats what i think, anyway i noticed these cameras have the same twist and lock video cord but the power end has a two way split that you can lock in with two little screws you can tighten into the cameras end, they also have the controls on the camera it self which you can control the focus, view, etc, its heavy and has many IR led's, i tried connecting it to a 12V 5A power supply but they show wavy lines on the monitor and my tv, and when i try connecting more than two they get worse and once i connect three, the third one turns on and off constantly, which makes me think they arent getting enough power, hopefully i can receive some help from anybody on here i would really appreciate it, thanks.

 

P.S. im going to provide a pic of one of the cameras maybe somebody can recognize them.

Sounds like that your power supply isn't regulated very well. The specs on that camera say that for 12VDCV, it pulls 750ma. A 2A regulated supply should work well for each camera or an 8A supply for all 4. You could try a 5A supply for all 4, but it better be regulated well.

Like I said before im new to this and I didnt mention it before but im going to attemp to set these up myself, so I hope its ok to keep asking questions that way I'd have a better idea of what I have to do, to do a successfull job. What do you mean by very well regulated, are there settings im gonna have to mess with? Wouldnt connecting them all to a 24v ac be better? And if its possible can you link me to a supply you think would be more than enough for these cameras to run on?

Hi. Stay with 12v for now .... Your cameras may not be duel voltage.... If you already get an image from your cameras with using 12v then that is a start.

 

What cable are you using for video and power ?

Tomcctv, that camera is a dual power camera.

 

Here is the link that I posted above:

in fact it is dual, but im going to provide you guys with pictures so you have a better idea of whats going on over here on this end.

 

from top to bottom are the plugs that im using inside that go behind the dvr and the power supply

 

and the bar from the power supply im currently using with an 8 split even though i only need to use 4.

and for the connection outside i kinda had to modify something my self in order to power the camera.

 

from top to bottom is the cable that comes from inside to the camera i had to cut the power end, split and strip the positive and negatives to fit into the cable that comes from the camera, which is the last picture.

Hi. Your bad image is down to poor cable ....

 

While you are doing the install ditch the cable kits you have and go for RG59 with power

[youngslick509 0]

that RG59 do you have to add the ends on the cable your self? and what power supply should i use for that kind of cable?

Hi. Yes you will have to put your own BNC ends on ... Or you can go cat5 cable and use Baluns .... Either way is going to be a better way than the cables you are using which are poor for CCTV use.

alright, thanks for your help both of you, im going to have to look for these cables now and work with the ends, hope it works, if anything i'll let you guys know, thanks once again.

Not that you may be interested but I had a client who was using the cheap cables that came with their system and one of them went to crap. The DC part was good and they didn't want to have to put ends on the better RG59 cable. So, I cut a piece of RG59 cable, put the ends on it and they just ran it beside the original cable and used it for the video. Fixed their issue. I'm not trying to sell you a cable, but you can purchase premade RG59 cables at several sources. Here is a link to what I'm talking about.
