What's an invisible fence system?
Question:
Answers:
It is a system of sensors and beams and signals,that if a dog is wearing the receiver collar, it will give them a very unpleasant shock, and condition them not to leave the yard,
it uses an underground electric wire like an electric fence. that emits a shock when the radio pick-up (on a dog collar for example) goes near it
If you are talking about the one for pets, it's a small cable placed slightly under the sod around the perimeter of your yard. The dog wears a collar that will give him a slight shock when he trys to cross over the boundry.
it's for dogs. you put it under ground and you can keep your dog out in the yard and if they try to get out it won't let them. your dog will have a specail collar, anyway they will not want to get out because everytime they try to it will shock them.
The idea behind all underground pet fences, regardless of the manufacturer, is the same. In all of these systems the transmitter uses the buried loop of wire to broadcast a radio signal. The signal is normally very simple -- just a sine wave, or possibly two sine waves at different powers. The buried wire acts as an antenna and turns the signal into electromagnetic waves.
The transmitter does not use a lot of power, so the signal around the wire has a very small range -- perhaps 10 or 15 feet. In some systems the wire has two signals running through it -- one at low power and one at a higher power. In these systems the collar can detect different distances from the wire to provide different levels of correction.
Inside the collar is a small radio receiver (essentially an AM radio very similar to a $5 battery-operated AM radio you would buy at a discount store). When this radio gets close enough to the buried wire, it receives the signal that the wire transmits. The radio triggers a correction so the dog knows it is nearing the boundary.
The underground wiring installed around the perimeter of your yard loops back to the transmitter that you have plugged in a safe, dry location (it is also recommended that you install a lightening rod near the transmitter to prevent blow-ups). The transmitter controls determine how wide the electric field is from the installed wire.
It's a signaling system used by pet owners to condition their dogs to stay in the yard. There is a receiver on the dogs collar which send a small shock to the pet whenever it comes near the sensors.
The problem with it though, some pets will run the wrong way from your home, outside the area and can run away.

right dawg?
It's a containment system for people who value the look of their property over the safety of their dog, and who have no problem using physical pain as a containment tool.
A determined dog can go through it (and then not get back in his yard because of the shock), and it does absolutely nothing to keep stray dogs, trespassers, or wildlife off of the property.
(No, I don't like them, why do you ask?)
