Basic CCTV questions

[video321]

I tried searching but couldn't seem to find the websites for either of these. I found something for Worthington but I don't know if I have the correct site. I didn't see them selling any rackmount power supplies. Could you post the links to the stores you were referring to? Thanks.

I recently received my DVR and CCTV cameras. I ordered the Vertiline 3D to power the cameras but it has been on backorder and I'l still waiting for it. I bought these adapters for the camera location. Back at the rack can I strip the power adapter that came with the camera and attach it to the 2 cable conductor (Siamese cable through the house) with a wire nut to pass power to my camera until the Vertiline arrives? I'm not very familiar with all of these things but it seems like it should be pretty straight forward.

I use those same adapters (I use them with CAT5e), and have no problems at all. I do use a centralized power supply, but the concept is the same.

I've spent the better part of the day trying to set up my home CCTV system and have hit what I'm concerned is crippling problem. The main location I'm trying to get set up is by the front door. There is a siamese CCTV cable run from the location to the rack. The cable is successfully passing video but doesn't seem to be passing power. I tried hooking up the camera with its power adapter and an extension cord and that was how I could tell that the video was being sent. No matter what I try though I can't seem to get power to the camera via the siamese cable.

There is an 18/2 cable that has a red and black wire. I'm using this adapter at the camera location and this adapter back at the rack. At the rack I'm hooking it up to the original power block that came with the camera. I tried using both the red and black wires as positive and negative and have always made sure that they're hooked up the same (either both red or both black as positive/negative). Regardless of what I try though I can't get power to the camera through the 18/2 cable.

I'm hoping somebody here can give me a suggestion. It seems incredibly unlikely that the 18/2 wire would have gotten cut somewhere along the path but the coax is still fine. The cable is behind the wall and if I can't pass the power through the 18/2 cable I'm likely going to have to abandon the project. Thanks.

Can you connect the 2 wires on the far end to each other, and test the ends closest to the rack with a multi-meter? You need to test the wire and figure out what's going on. Also, what kind of distance are we talking about? Long distances would have to deal with voltage drops (but that usually isn't too much of an issue with most cameras).

Check the voltage on the leads on both ends with the camera unplugged and also with it plugged in.
Disconnect both ends, twist the leads together on one end, and check the total loop resistence at he other end.
You'll need a DVM. I've seen them for about $5.
