The Electric Fence like other security systems deters people from scaling the fence wall. It therefore prevents unauthorized visitors.
The Electric Fence is powered solely by electric energizer that regulates power distributed into the strings. If wired correctly the electric fence will alarm when the wire or string is cut or tampered with and strobe lights blurring.
The shock one experiences when any of the wires is tampered with is such a magnitude that will not make you dare again. The major components of the system are: the strings and bars makeup the fence, the energizer that powers it, the siren, strobe light and warning sign, the energizer has a back-up battery that stores power.
