No signal on lcd screen

Recommended Posts

Hello,

 

Today I went to a client to replace a cctv camera that was broken.

When I replaced the camera there was no signal on the little car monitor that was placed in the kitchen.

There is a good video signal to the DVR tho so the camera is working. The camera is connected to a splitter in the attic and goes from the splitter to the DVR and to the car monitor.

 

Why is there no signal on the car monitor?

Are the cables to long? the video signal to weak?

 

Thank you!

splitter? is the cable coax or utp? what is the spec on the splitter, how is it labeled, what exactly is this car monitor, what dvr, what camera spec cvi, tvi, ahd, sdi, etc ? All of these things matter and without a more detailed description no one could give you any real answer.

Hello,

The dvr is from dalhua 4ch dvr the camera's are can280 - pal,cmos 1/2"

The splitter has no specs it is just a t splitter (see picture) and the system uses coax cable. The lcd is just a small 9" lcd like they use in cars it has no brand.

I'll try it with a powered splitter. Thanks! I just took this picture when i was with the client. Is it a sign of a low video signal?

That looks like a defective camera image. The rest of the image is perfect, so there's no weakness like static or lines across the image.

Hi. T connectors never work to distribute CCTV signal.

 

How is the image on the mini screen if you go direct from camera ?

 

 

But what you need is a 1 in 2 out distribution box at camera end.

They are cheap and the right way to go

good ideas, on the powered splits, I'm also wondering if there is a video format issue with the little monitor. No specs means just try it and see. Put it in place of the dvr and look, is it good or the same? Same means monitor isn't compatible.
