PIR Motion Detector/Home Security
Posted 05 September 2013 - 10:46 PM
If I'd realised the seriousness of your plight, I'd have advised other than my previous.
From your posts, it seems obvious how unnerved this event has left you, and I don't think that you'll find peace with any alarm system as false alarms are going to soak up the last of your nerves.
The only system I can suggest is one that employs CCTV with motion detection. If the occupants are watching tv and an activation occurs, the tv will switch to that particular camera. That signal is triggered by a 12v signal via scart. I can only suggest that the 12v signal be tapped in to and used to trigger a sounder of some kind, audible to all of the property/premises, to also alert anyone who is not near a tv that an activation has occurred. The activation can light localised floodlighting, or leave IR cameras hopefully capture the scrote/s in all their glory and get a better pic as they won't even know they're being recorded. Audio can be captured too, further incriminating/identifying the f*****s. The position of the cameras needs to be considered very carefully so as to make the detection strike as targeted as possible in order to be effective enough to offer some kind of feeling of security.
Hopefully you'll find a way to get some comfort, maybe a combination of what's been suggested, but budgets going to be big.
The CCTV can be recorded virtually via the Internet, so that intruders could not demand the "tape" to be handed over or destroyed, basically once the scrote/s are on TV they're there to stay for the authorities to review and possibly apprehend them later.

Nick/JSH: CCTV with motion detector will be good but you can imagine the area is quite big and it will cost a lot! I will try to get a motion detection system which is intelligent enough to exclude any animals. Furthermore I want to make the system very discrete. A combination of things will need to be employed in my situation. I have looked at the honeywell products and the motion sensors are quite cheap so thinking of getting a few of those. Add them to boundary wall corners with the lights attached plus an alarm. Got to be a wireless setup though.
I have found out about a radar system but the cost is about £25k!!! just for the core stuff. It can also have a high res camera which can pin point at a long distance. Not going this route due to the cost...
Thanks appreciate your help.

The sensor is their order code LM GX200/40 and they are £36.60 each for quantities of 3+

Do they do it with an iris-type mechanism?
How would that device work when sensing?

The 40 metre range unit is this one: http://www.tlc-direc...200slash40.html but it's not at all clear as to whether that 1 deg angle of view is just a narrow pencil beam or whether it's a flat fan shaped beam.
Edited to add:
I've just seen the link to the instructions, here: http://www.tlc-direc...ite/LMGX200.pdf and it looks like the beam is more or less a narrow pencil type shape, so not a great deal of use for long distance perimeter sensing over a wide area.

External detectors often have very specific mounting heights and should consist two separate detectors in a single housing, this works by one point low and one point straight across and both have to be activated to generate an alarm. Animals rarely cross both sets of beams, larger the animal the more likely to cross both detectors, but you could be burgled by very short people.
GJD do several hardwired and also do a wireless that work with Texecom panels, Texecom have Premier External TD, Premier Elite Orbit series, and Risco have WatchOUT and do barrier beams but there are many others, have to admit the prices are not exactly cheap.
The siting of any detector is the key to eliminate false alarms, if the devices are going to have direct sunlight issues, you can get DT's which can help, often used in conservatories or other detectors which have been designed to eliminate that cause.
When buying detectors, I would buy one that is made by a company trading in the trade in that country and not purchase something made in china by A N Other.

Just thought it may be good to add the mention of 'duress' silent activation.
With most modern alarm systems, you can type in a duress code which will deactivate your alarm system.
Basically, if your forced to turn your alarm off by anyone ( intruder etc ) then you type in a different code to your regular one and this gives the impression that you've turned the alarm off as 'requested' and all is well. In fact, the duress activation will have triggered a silent alarm activation and text or dialled out via your dedicated telephone line to alert relatives / friends / or monitoring company that you have been forcibly made to turn off your alarm. They will then be able to alert authorities / other as to the severity of the situation.
That's much better than an alarm box wailing in the distance, as the duress code would be a specific, unmistakable call for immediate help.
The duress code i suggest to my customers is a clever and simple one, so even the kids know and remember it. I also fit Personal Attack, ( PA ) buttons by the master bedrooms and front & rear main entrance doors so if you don't like the person you've just opened the door to you can let everyone know with a simple button press. I locate these close to, but behind the doors, so you can access them easily but they cant be seen by the person at the door.
Mine is connected to a roof mounted cauldron of boiling oil, ready for when some penis asks me if I've been in an accident, or have paid PPI recently. :-@.

What someone really needs to invent is an incredibly high current device that sends a powerful jolt down the line to the automated system that rings you when you're at the top of a ladder and talks about PPI, or how much the building society you've never dealt with owes you. Such a system should be able to detect certain key words and the jolt should be powerful enough to cause every work station in their office to self-destruct.

It's a bit 'funny' to work with but gives you the maximum flexibility if you are into software engineering to make an solution to any problem
