Cctv General

[mrsfedup]

HI EVERYONE

just wanted to know that if we are installling cctv to capture an intruder is it important that the time and date are caught on the image too ,as it will be used as evidence ?

thank you

[breff]

Yes it is, and if you are recording digitally it should be 'digitally watermarked'

[mrsfedup]

hi there thank you for your quick reply,

would you know of any that do this that are quite cheap , i was looking at the ones Argos have to offer the Get range, it was 2 for

dont forget there are rules about the image for identification purposes

ie to identify a stranger they need to fill 120% of the available screen

if you are using tape it has to be clean before use

you will need a continual event record of the incident

and log who does/did what witj the system before and after the event

it really is a lot more involved than that but i still have to look the info up every time we quote a system its unlikely anything you could buy in the public forum is goingto have the police jumping with joy and running round to arrest the local yobs

as sparky192 ( hello by the way please pm me sparky)says get a couple of quotes from the trade there is a reason it will be so much more expensive and trust me at aint all profit lol

head to knees fill the screen

to identify a member of staff its 80% whick is still bigger than the matcksick people you usaually see on crimewatch

remember to that a 3.6mm lens is only in focus at a distance of 1.6 meters away so put one looking at a door to a shop will be ok put one behind the counter looking at the door its not admisable as evidence !

That may be so but most systems are sold to identify a KNOWN person...how do you fill 120% of the screen cos you only get 100 %....or perhaps i am being thick

[breff]

from top of screen to bottom of screen= head to knees or better, for instance if the whole screen is seeing just a head its probably more like 600%. think of it as a zoom, if a person head to toe is 100% and you zoom 200% then that is head to waist.

no there not! the corner shop isnt going to know the yob coming to do the till or they would be doing another shop

you should have one camera to take the ident shot as breff said better than knees to head then you cannot lose sight of the person at anytime until they leave the shop have a look next time you go to your local spar or natwest

problem is you probably need 6 cameras to cover the local corner shop when the owner rings up and says i want a camera please its an impossible sell thats why we only do cameras as a last resort for existing customers most of whom actually want a set of external sensors and a buzzer instead when its explained to them

this is all before you get into presenting the footage as evidence and the cps get their mitts on it

we have had digital footage that matched the custardy suite stills better then dna and they still woulnt prosecute

big shops with camera opertators remote viewing thats a different matter

Not strictly speaking true.

In law all video evidence is admissible in court, however bad it may be.

Although most of the information contained in the read is good as the better the system, (accurate time and date, digital watermarking, evidence handling procedures, size and clarity of image etc) add to the weight of how serious the evidence is held in court.
