Check the monitor first, are you using BNC, VGA or HDMI out of the DVR

Thanks Nova. 

The DVR has a built-in monitor and the images are identical when viewed online. It does seem that either the signals to the DVR are suspect, or it's the DVR itself that is processing the signal incorrectly.

 

Thanks for your help

Cameras are TVI when the system isn't.

If the DVR is analogue then I'd say your DVR was incompatible to receive the signal correctly you need a hybrid DVR is one that can see and cvbs tvi and cvi signal not just cvbs

Thanks for this... obviously I'm out of my depth with this.

I've not got all the paperwork with me, but I know the DVR is "analogue" and understood the cameras were too. However the question of tvi/cvi is unknown. 

There IS a picture (it's a shame my small video file was not viewable to you all) but it's showing hazy interference. 

Would I still get a picture if the tvi/chi was incorrect?

Thanks again to you all for your help. 

regardless your cameras are too high

you would be better with sd cams at the right height

Yes.

I also agree with James that the cameras are positioned incorrectly.

Also note Sannce are Chinese DIY tat that are one of the manufacturers known to have been compromised if you are planning on putting it on the net.

Cheers James.

So you can see the video? That's great. 

The DVR shows 1080p, and I recall the cameras also being 1mp 1080p (I'll be able to check this when I return to the customers house).

So, lower quality cameras might be the solution?

I suppose if I'm going to get asked to look at CCTV regularly, I should attend one of the ADI events and get clued up!

Cheers

Thanks also SWB. I'll propose that the cameras are moved.

 

Cameras may have a menu to switch between formats, although best to check that, I don't fit Hik.

Your fighting a losing battle unfortunately. Although the councils that can't spec it still do, bit like huawei...
