help with video picture ghosting

Recommended Posts

Hello all,

 

I have 2 questions:

 

(1)

I just installed a standalone dvr from http://www.surveillance-spy-cameras.com/8-channel-deluxe-real-time-embedded-DVR.htm and three cameras. @ are samsung SIR 60's and then a outdoor PTZ dome Veilux VP-54CDN10X. The question I have is when I look at it online or on my computer, the quality looks good, but when I view it on my 40 inch LCD tv in my bed room the image looks distorted almost like it is ghosting. I have the DVR hooked up in my master bedroom closet since that is where our junction box is for all cat5 and rg6 cables. The DVR has an VGA and BNC video out and I have it hooked up from BNC out through RG6 to the feed where my TV is at, then I have an adapter from "F" type connector to a "RCA" or composite and then connected into one of my video inputs. Is this a bad way to go? I thought maybe the signal was degraded due to the adapters and got a signal amplifier, but it made no difference. What should I do?

 

Second question is on the cameras when they are in night mode I am noticing a "flicker" i guess is the word I can think of. About every 6-7 seconds like clockwork the screen flickers with like floresent static for just a second and then 6-7 seconds it does it again. Now this only happens when they are in night mode? Do you know what could be causing it or is this normal?

 

Thanks again,

 

Richard

The way you connected to your TV is just fine. Now if the run is really long, then you might have some signal problems.

 

The flicker could be caused by an inadequate power supply. At night when the IR comes on, more power is used.

A termination for video is a 75 Ohm resistor placed at the end of any video cable to prevent signal reflections that cause ghosting or multiple images on the monitor. Some CCTV equipment have built-in terminations some of which are switch able. If you are using this equipment in series, you must switch off all Terminations except the termination at the last piece of equipment in the cable run.

 

Also change in impedance can cause this so if you have converters in place remove them and see if the problem still exists.
