An electric fence can detect, deter and delay and delay an intrusion. A high voltage controlled shock combined with a physical barrier will deter any one from attempting to penetrate the perimeter fence.
The detecting ability of an electric fence energizer will sound an alarm when perimeter of the [remises being protected has been infiltrated or tempered with by keeping the premise protected using an electric fence, the attempted break in of the protected area is displayed, giving addition time for a reaction team to respond.
If someone tries to sabotage the fence wires by cutting or shooting, this triggers an alarm and can be used to warm the security personnel of an instrusion
How an electric fence works
An electric fence energizer converts mains or battery power into a high voltage pulse. The energizer releases this pulse on to an insulated fence line about once every second. The pulse itself is only around 150 microseconds long.
This pulse is commonly referred to as the “shock” and is felt by any animal which touches an electrified fence. When an intruder makes contact with the fence the circuit is complete. It is at this point the intruder receives a shock.
