CCTV 4 channel DVR card

[ian.cant]

My simplistic advice is often to source the best quality of equipment available within a budget, but not to assume that the quality issue is the only relevant solution.

I would go along with that as a general format to follow, getting the idea of the budget is difficult i find. Most people think if they dont tell you, you will be cheaper i assume. Even if i ask for a budget and explain why they are more often than not reluctant to give me a figure. Does everyone find this?

Yes. Most of the CCTV we deal with, the clients never have any idea of budget, and just need a solution, and then die when they find out the cost. We determine exactly what is needed and will provide an optimum quote, probably with a cheaper option - or at least make it clear that cheaper can be got, but with clear disadvantages (at least that way we have a better chance of them coming back to us rather than going to Mr Cheap and Out-of-Business tomorrow).

The problem is too complicated in technical detail for the space available here but in essence if we understand that a conventional 44 degree FOV lens on a 400 TV line camera transmitted to a DVR cannot decode a vehicle registration plate beyond eight metres but this camera is then fitted by a brilliant expert of an installer - probably Robin Hughes - at the top of a 12 metre pole. You will see where the problem starts.

The other day I received a visitor who gleefully told me he had solved the problem of the atrocious quality images he had been producing with his DVR. He told me he had purchased a new camera with claimed performance of 600 TV lines. This man, probably a relation of Robin Hughes,just sat there dumpfounded when I explained to him that he had wasted his money.

Someone forwarded me this link

Freudian slip Lee? Were you refering Tony Hughes from the preceding email?

Why do I care> Because I am a Forensic Video Analyst for a Police Force and every day I have to throw away 80% of all material made on **** DVR's because the result is not good enough for evidential purposes.

Regards to all.

Hi Lee,

i've read through this thread with interest, and i like others value your input from a perspective we are not often privvy to. as installers we are often asked to cover a car park with one camera then get number plates or facial recognition too. so then we have to talk the client through focal legnth of lens wide are = small target, and narrow view = less cover but better recognition possibility and if they really want number plates throw in3k for a specialised camera.

if a good camera can be placed at stratigic point such as an exit, or a travelling vehicle can be slowed via humps or chicaine to reduce blurr then we can get good results, but it may not be physically possible to achieve an ideal location due to the cost involved or the layout.

many supplier's offer cheap dvr's and even these can give fair results if set up correctly and camera's located and set up properly, like HiFi and computers, rubbish in is just plain enhanced rubbish out.

i would say most professional installers while obviously making a living, also want to give the biggest 'bang per buck' to their clients too.

while aprreciating you dislike for 'general coverage' camera's they do offer some assistance in knowing which way a perf/s entered and left to the scene and how many were involved. so allow the Police to make more informed enquieries, if they track down one of the guys in your picture, they can bring pressure on him to name the others, balance that against having a good picture of a face but only one wearing a hoody.

if we instal the touring type camera (visa v BP Connect garages), very clear high definition images are given. reviewing the footage, especially if you do not know the time and date, can be a nausiating task for the reviewer.

i think we would all prefer to use the highest quality kit available, but that cost's far more money, and the clients do not often appreciate it in relation to the benifits. it's what they see usually as preventative/deterrent measures rather than after the fact.

even when images have been superb many clients have little faith the villain will be caught, and if so prosecuted, and if so gets a good sentence so why should they spent thousands? is their understandable sceptic's view.
