Poor Earth Grounding One of the biggest problems with electric gates is poor installation. In particular, many people do not properly ground the gate or fence during installation. Grounding rods must be placed under the gate in order to keep it safe for people and animals. Drier climates require more grounding rods. An improperly ground gate can cost thousands of dollars to repair. Barbed Wire Fencing Some farmers have tried to electrify a barbed wire fence, but this is a major safety hazard to animals. Animals can get stuck in barbs whether or not they are electrified, but the added electricity can lead to their death. Barbed wire should be avoided on farms and should never be electrified. Interference Occasionally, electric gates may experience technical difficulties due to interference. Local radio, television, or telephone signals or wires can cause the interference for both the media system and the gating system. Such interference can cause the gate to lose its electric charge temporarily. The interference can also cause brief spikes in electricity in the gate, which can be a safety hazard to people or animals. Insufficient Animal Training Since electric gates on farms are intended to keep animals in their assigned area, the animals must learn about the consequences of crossing the electric gate. Farmers or property owners must therefore train their animals to avoid the gates. To train the animals, owners must actually expose them to the electric shock. Owners who fail to shock-train their animals may find that their animals become obstinate or may get seriously injured. Crime Target Owners who install electric gates at the edge of their property often do so for security. Ironically, the presence of such high-tech gates may signal to would-be robbers that the owners are very rich, making the owners theft targets. Property owners may want to install an alarm system to accompany the electric gate to increase security.
