Picture quality not sharp

Deerspotter

I have a kodicom CCTV system with 5 cameras and three monitors.
The picture quality used to be sharp, but is not sharp any longer.
I have unplugged each device and tried them all solo and the picture remains the same.
Someone suggested it could be the internal power-supply in the Kodicom box.
Any suggestions?

(By not sharp, I mean, all the pictures vibrate the same way, and straight lines have diagonal interferance.
This is not obvious on smaller screen (4 pictures on one screen), but very obvious when one picture on full screen.)

Power supply sounds very possible.Can you give us a little more information.
What type of cameras are you using here , are they using a single lead for power & video?
What model of DVR do you have?

The box is kodicom as are the cameras.
They have co-ax and low voltage power supplies.
The quality used to be perfect, but somehow it has declined with out my noticing.
I turned on the bog screen today and could clearly see tiny diagonals on black straigh lines (such as a gutter down-pipe) and hues around red colours.
Not so obvious on smaller screens, so I cannot say when it happened.
Nothing has changed in the set up though.
Even though I unplugged each monitor and each camera and plugged them bacl on in one by one - the result was constant.

Was hoping for the model of the machine , not to worry..
So has each camera go a seperate power supply? What voltage are they?

Deerspotter

each camera has a seperate power supply and they are 12v.
The kodicom box is 240v and has an internal powersupply.

It is unlikely each power supply has a problem. What I would be doing at this stage is feeding each camera directly into a monitor & see if the picture is ok. If all is good them the problem is in the machine (DVR) itself.

I think the cameras have to go through the DVR, as when they connect directly to a monitor there is no picture at all!
Could that be?

KoolKid

what type of connection is on the cameras & the monitor?

Deerspotter

RG 55's camera to DVR, RG 55 converted to AV connector into monitors

KoolKid

The monitor should show this directly.

I will give it another go this evening, maybe something went wrong.
You are very helpful.
Thank you.
Do you know, if it is an issue with the box, where might I get it serviced?

KoolKid

I honestly do not know of any agents over here.
They have a European branch in the UK
Kodicom Europe
Kingsmill Business Park Chapel Mill Road,
Kingston Upon Thames,
Surrey KT1 3GZ

They might know more.

IGT in Lucan sold these, not sure if they still do.
But I would connect the cameras directly to the monitor to rule out the dvr
