I'm buying a system with the power being supplied directly from the NVR. I will be running very long distances. Also how can I extend the range of it if necessary?

The camera is powered from a 16 channel power supply box. The cable length is ran from the 5th Floor to the 1st Floor. Thanks

New rg59 was ran to the camera. From time to time the camera would get fuzzy and go black. Then it would go back to normal. I included a picture. Thanks

Try your cables both BNCs and power cable terminations. At the dVR end simply move them about and inspect them closely

Look for efflorescence (salt corrosion) at the camera end either on the connectors or in the cables.

Inspect the camera to see if water or moisture has infiltrated (unlikely)

 

If your camera is supplied exclusively by a single power supply swap it out with another to see if the problem moves to another camera.

Keep a record of all the things you try which will help you in eliminating the fault eventually.

Thank you very much for your help.

What is the voltage at the camera?

How have you connected the camera Cat5 with Baluns or Coax?

Have you tried the camera over a very short cable in the house perhaps?

I am using Siamese Cable with RG59. The power source is coming from a power supply box. The camera was fine for couple months and now the flickering is happening.

Towards the 15th second mark, you can see where the camera is flickering. During the night time, the camera seems to be more stable. Thank you

Could I attached the camera onto the blank cover?

 

Yes, that's the idea. Just carefully drill the needed holes. Search around on the net or in store, there might be a stronger one (It's hard to tell how thick/strong that one is form the photo). It should be ok, cameras don't have much weight, unless a fat bird decides to nest on top of it. Almost any box cover can be used. If the camera doesn't have a moisture cap of the cable (or if you can't use it) electrical tape is perfect.

 

Here's another box, with a cover too. And it's very strong. http://www.homedepot.com/p/Carlon-15-15-cu-in-Type-X-Round-Conduit-Body-E970CDE-CTN/100404094?N=5yc1vZbohnZ1z0usncZ1z116nv

Thank you very much. You have been very helpful.

Do you know what kind of conduit is compatible with that junction box?

Can you provide me links to items needed for a conduit installation for rg59 cables? How do you connect bullet cameras to the junction box?

Thank you

I am using a QH8003B bullet camera. What kind of junction box should I use for it to conceal the connections and the cable coming out of the wall?

 

Thank you very much.

 

I'd suggest something like this http://www.homedepot.com/p/Bell-1-Gang-5-Hole-Non-Metallic-Round-Electrical-Box-PRB57550WH/202284522 and this to cover http://www.homedepot.com/p/Bell-1-Gang-Round-Blank-Plastic-Cover-White-PBC300WH/204155109?MERCH=REC-_-NavPLPHorizontal1_rr-_-NA-_-204155109-_-N. They come in other colours too.

I bought this cable on ebay:

Is this cable ok for outdoor use with direct sunlight?

Is it ok leaving outdoor rated Siamese cable outside exposed?

you should probably get a small carlon box and put your junctions in it. It is also best to run some sort of outdoor rated cable

Thanks, I never knew what they were called.

What kind of terminating connectors to use for the power line to the camera?

What kind of waterproof connectors can I use to terminate the ends?

The rg59 and 18/2 power

Thanks
