Like I said, a vcr is almost the same output, my school use coax in the library and it looks awfull, there is no definition, you can hardly make people out, in the hall however with the same cameras, they use s-video and it looks much better.

My point is if you connect a vcr by coax and scart you notice a big difference. At school they record both pictures in digital but the s-video one is better, since the cctv cameras output is analogue and low res though it doesnt make a difference between recording formats.

Ahah, i think i see where the confusion is here. Think you're confusing RG59 coax with the RF coax you'd run an aerial signal with. What cable would you use to connect the camera to the scart socket? Coax. Or a composite signal? Coax. The signal type is the same.

Night shot, its pitch black we have no street lighting here and these are the cheap swann cameras, so for the money there quite good. Going to get two pan tilt and zoom cameras later this year.
Camera 2 is a wireless camera.
Spinal2k2 you can also view this setup anywhere in the world just enter the ip and password and can watch your home.

Lord save us from the mighty wisdom of schoolkids.
Because the signal going down the coax cable in those services isnt uncompressed analogue video its compressed digital...
Which means it takes up 10x less bandwidth and chroma/luma data doesnt need to be cut out of the signal. However if you connect your tv to the box using coax the picture quality suffers because the box would be outputting analogue video through the cable.

It's getting late and i'm gettnig bored of repeating myself. In the real world RG59 coax cable is used for CCTV installations because it's the best thing for the job.
You don't get (or at least i've never seen) a camera with anything more than a BNC connection (ok, you get an RCA connection on the cheapo CMOS based cameras, but the signal type is the same). It doesn't matter if it plugs into a BNC, an RCA, a scart socket, the signal is the same.
Energise, i understand that you have a wealth of technical knowledge on the subject, but real world installations are done to a standard, not a theory.

It seems to vary for police force to police force. I've recently handed over footage (megabytage?) of a bunch of scrotes vandalising an area. The camera was on the back of a shop, with no warning signs in view. The police were quite happy to use the video evidence.
I've also heard of some viewing it as once a person comits a crime they forego the right to be warned their actions may be monitored. Or something like that, it's late!
I have footage of local scrotes vandalising my car. Contacted the police (Met) wh asked me if I had signage warning of CCTV. When I said I didn't, they told me that they didn't even want to see it as it would get them nowhere. I was fuming, as even if they couldn't be prosecuted, if the police could identify then culprits, they could at the very least let the parents know that they were aware and watching.

Get a better camera.

You can get digital cameras that have better than coaxial outputs like I said, I was trying to make a suggestion to the op so he wouldnt have video like the screenshots posted earlier, so he could actually make out the people on the video, Ive seen crimewatch and the cctv most places use is crap, you can barely make peoples faces out its a wonder they catch anyone, bad cctv is as bad as not having it at all, if you cant get a clear picture theres not much point in having it and a digital camcorder is a cheap way to get a great, sharp picture at a decent resolution.
