boundary wall intrusion system!

[ibrar0]

Hi, All i want to build intrusion system for boundary wall of factory whose length is near about 30 meters long. for security purposes.
Normally IR transmitter and recievers are used for short distance to build same thing,
but for this which things i should use any suggestion if schematic, it will be the best thanks

any help???? is there no suggestions???

Intrusion system

I use a wire on top of the wall pulsing 25KV every 1.5 seconds. This system has a broken wire detection circuit to tell me the exact location of the interruption. Furthermore a second circuit measures the resistance while the HV is interrupted. Shorting the wire with a piece of copper cable decreases the resistance, hence triggering the alarm circuit, using higher resistance connectors will have the same effect.

The system works perfect - I already have hundreds of dead burglars laying on the other side of the wall.

You're too nice. This is an American solution:

It's just the same as mowing the lawn with a kitchen knife. Another American solution fires 6.000 rounds per minute. (Cal. 23.5mm)
