At the risk of being a totally boring old f@rt, I just thought I ought to throw a couple of basic comments in the pot.

If there is an ongoing vandalism problem, ideally, it would be sensible to go covert first to identify who is doing it. Once caught, the covert camera can then (if appropriate) be converted to overt as an ongoing deterrent. If a visible camera is installed from the outset, it generally deters in about 75% of situations, but can have the effect of triggering other forms of ASB (anti social behaviour), outside the range of the camera. You can always successfully go from covert to overt, but rarely the other way around.

I think Peter James suggested that mounting the camera too high would be detrimental (apologies if I got that wrong), and I would have to agree wholeheartedly. The 'Cone of Containment' is completely wrong for a camera mounted in this position, as you will need to use a wider angle lens to achieve the vertical coverage, and that will produce smaller targets on the recorded image.

Personally, I would have gone for a very sensitive high resolution monochrome camera, mounted in the top corner of the downstairs window (provided of course it gives the desired coverage), and looked to upgrade the porch light which can then be left on all night. If a tungsten bulb is used, that will throw out lots of invisible IR allowing the B/W camera to produce a much brighter image, then would be suggested simply from the visible light level.

Using a 'box' camera with CS mount varifocal lens (personally I hate varifocals!), would allow an inexperienced user to frame the picture on the nearest parked vehicle (plus 1metre each end), and should give a very good image.

Incidentally, it would be preferable to park the red car nearer to the property, as it would benefit from the lighting more so than a silver vehicle (inverse square law and spectral reflectance .... don't even ask!!).

Service Engineer,

Just curious really, did you ever buy those cameras? What are they like? Do you have any night shot photos? What is the quality of the images? Can you send some examples?

cheers,

Mike

TBH the quality of picture as the unit arrived was spoilt by the poor positioning of the LED's as they reflected off the dome cover onto the lens and were then visable on the image.

After removing the LED's (which I felt I had to do), the image was better but only as good as the fixed camera I already had. For

I had similar problems to you last November. Coincidentaly, I was installing CCTV at the time anyway and were able to identify the people responsible after a couple of days. The police went round to their houses and got them. My IR camara is a 50m one but it only really can see faces at 8m with some background illumination.

I'm upgrading my system now so will follow your post.

Does CCTV work. Well I'm still a bit uneasy in the evening sometimes but at least I know that any thing is being recorded on motion detection. I've not had anymore problems and any kids now walk on the other side of the road but the CCTV still gets them over there anyway HaHa.

If you go down the pc route get a dedicated pc for the job. Mine was

It's been 20 days since my decision to install CCTV to my property and my search for a camera has been some what frustrating because there has are so many cameras on offer, and even though advice from everyone on this forum has been amazing, I am still a little apprehensive about rushing into buying a CCTV kit i know nothing about.

But I want to wrap this up as soon as possible, because I have CCTV on the brain and it cannot be a good thing. So I have compiled a list of cameras I am interested in. I would appreciate your thoughts on the cameras and please feel free to recommend a similar camera. I am not interested in a cheap alternative (e.g. an EBAY lookalike, or a gadget spy camera). I have �350 to spend. That is a maximum, so I am expecting everything (box, cables, psu, lenses, mounts etc) for that price. :yes:

If you need I.R then the CC70 from R.F. is a good unit, we have used hundreds of them.

Speak to R.F about which lens you require (ask for Roy or Billy)

Beware of spiders with this camera tho.
