Bad CCTV strength Supply? Make Sure!
If you have a multi camera surveillance system; then most likely you are using a CCTV strength box with multiple inputs to strength all of your CCTV cameras. Sometimes if you’re surveillance system goes offline and it seems that your strength supply is bad; that may not truly be the case. Let’s go over a few steps we can take to make sure that is the problem.
First Step Or Last Step
The first or last step can be to take another CCTV strength supply and replace the one in question to find out if you start receiving strength with this new one.
Now this is an easy first step to take for a surveillance installer or dealer as they would have quick access to another strength source most likely. For an average installer or customer; this may be a bit trickier to do and really would be a last resort kind of scenario.
in any case step you end up doing this in, you will have 2 different outcomes. Either the new strength box will work and strength up your surveillance system; or it will have the same failings as the other.
If it works, then most likely you have found out that your problem resides in the strength box itself. however if this new box also fails; then you have most likely deleted the strength box as the source of failure.
Next Step – Camera Short?
If you have a security camera that has an electrical short in its connection to your strength supply; then this would force your strength supply to shut itself down. To test this it can take a bit of time, but you will have to individually connect each camera to your strength supply and test if one of them stops the system from powering on.
If you find a camera that is shorting the system out; then you will need to determine if it’s the CCTV cable or the security camera. To do this you will need to get a keep up of another strength and video cable or take one from a working source and test the camera again. If this works; then your problem lies in the cable and it needs to be replaced. If the new cable does not work; then you will have to check your strength connections on your camera, and possibly replace the camera itself.
Not A Camera Short? Try The Main strength Cable & Connection
Honestly this should be the very first step before anything else; because if it is at fault it saves you a lot of time. Each CCTV strength box will have a plug that connects to an outlet, and to test this you can try replacing the cable or you can connect it to multiple outlets to see if the outlet is at fault.
Check The Fuse
If you are only experiencing strength outages to certain security cameras; then you may have a blown fuse (Assuming Your Using A Fused strength Supply). Most CCTV strength supply boxes come with spare fuses, and replacing your fuse may do the trick.
By trying these various troubleshooting methods; you can more precisely determine where your CCTV strength problem lies.
