    There are a couple of solutions to this issue: 1. If you still have a VCR, plug your camera into that input, then the output to your TV.

    Add a Comment2: Go on eBay, etc, and get a inexpensive video transmitter. Input your camera into the Transmitter, and output the receiver into the composite input jacks (Audio - white-red, yellow-video), Select "composite" or AV on the TV input selector.ellow

If you are getting a completely blank screen on your TV then you need to check that your TV port is working (either HDMI if youre using this or CVBS). Try another TV/Monitor with VGA. Your question is a bit vague so it would help if you provided more details;

It is neither clear what sort of output your cctv cameras produce, nor what sort of input your dvr accepts. but, for the most part, dvrs record digital tv signals, whereas cctv cameras output analogue signals. so, even though you may be able to plug a cctv camera "straight" into a tv via a scart connector, it is unlikely that any scart connectors on a dvr have the necessary circuitry to accept such signals.

In my 4 camera surveillance system two cameras stopped working

The screen should say a message similar to "VIDEO LOSS" if it does The power packs or multi power supply to your cameras are easiest to check for starters. Unplug the power to a working camera and plug it into the non working camera close to the dvr. If the camera that didn't work came on, then the power pack is most likely the problem. If it didn't have a message saying "VIDEO LOSS" then it may be the sensor that switches to day/night vision. I have had cameras that when it switches to night vision the screen goes black and unplugging in the power to the camera and re-plugging it in gives it a boost and then comes on. If switching the power from a working to non working camera don't work get the ladder out and unplug and re plug in the connectors at the camera in case it is a connection there. Last if that didn't work would be to take the camera that don't work off and plug it into the end cables to a working camera, if it works then I would suspect the cable to the camera to be bad. Just a process of elimination.

I've got a problem with my cctv cnm 160GB H 264 4 channel DVR I have 3 cameras set up on it and 1 of the cameras have stop working I've checked all power and cables and they are all working fine the...

Remove all the cameras then reboot. If it boots up normally then shut down dvr and add a camera and repeat. If it doesn't solve the problem, the issue is probably a video card or motherboard issue and will need to be repaired or replaced.

Lorex video camera not working

First make sure all connections (Both at the cameras and the DVR are connected properly, hand tight.

Next I would make sure they system is up and running.
To ,narrow down the problem take 1 of the malfunctioning cameras and hook it up to where a working camera is hooked up (I would strongly recommend putting a label on each Camera (Working and not working)with masking tape and a black marker, same for the cables at the back of your dvr. i;e. Camera 1, Camera 2, Camera 3...ETC) And as for the cameras write known working on a piece of masking tape attached to each and if possible the cable it's hooked up to (just like you did earlier, camera 1 -4)

Now, with everything running, disconnect one of the no working cameras and walk over to one of the working cameras. IF there all the same cameras just unplug at the camera and leave everything esle as is. Now unhook the working camera, set aside, and plug in the non working camera. If this does not fix it, I would look at both working and non working cameras and make sure any switches that may be behind a panel are EXACTLY the same.(dont change the working cameras settings, just non working) If you have to change the non working cameras buttons try it again. Repeat with second non working camera. If the cameras still do not work then they are faulty. If they did work with or without making any changes to the non working camera then your cable ends and/or cable is bad)

IF none of this helps, try going to the back of the DVR and switching 1 known working cameras cable with a non working cameras cable. IF this fixes it then you unit is bad, if not, then camera and/ or cable is bad as discussed earlier. This should narrow down your problem and put you on a path to getting the system working, not that you know for sure where the problem is.

I have a sentient cctv dvr from Maplin I can view it on my phone at home which is fine I wanted to know if I can view camera footage when I'm not at home etc. at work

Yes you can definitely view your CCTV footage on your mobile phone at your work via internet. Sentient CCTV DVR basically is a night vision camera. You must know the IP of the camera and IP Video server. Connecting your phone to CCTV camera via the protocol you can view the CCTV footage's in your phone. Night vision cameras are used for surveillance purpose. I would prefer cctv camera with ir illuminator for good image quality in the night time that will clear footage quality in my phone.
Recently many new applications have also being launched by security cameras with a view to solve problem you mentioned.

How to hookup audio to home security sys

do you have audio cameras, they don't usually give you the audio cameras with a standard setup, on the back of the dvr there is a plug for audio its either a phono plug or a mic input socket, this can be used in one room or outside depending on the mic you have to buy. you then wire this up to the cctv and have to setup the sound to the camara number.

Where can Ifind help for installing a Ouku brand 4 channel cctv dvr?

I had exact same problem and it took forever to fix but I did fix it. If I plugged the camera into the tv it worked but when I tried going through the dvr no picture at all. The problem was the power supply cord to the cameras. It was bad, I happen to have another one and that was it. All cameras working!

Channel 3/Camera 3 not displaying properly

try swapping the cam inputs first to rule out the unit, if not the camera may be faulty or needs setting up properly with a focus adapter, or the lens could need setting up!
when CCTV company's set up these systems they have all the equipment to plug in and focus auomatically etc..
Hope this helps!
Try looking at (test equipment) section.
