Auto Safety Shut-off:

Perimeter® brand dog fence systems feature a built in safety mechanism. It automatically shuts off after 20 seconds of correction.  This safety features ensures no unnecessary correction for dogs. This includes dogs who may be in the boundary field and panic.  Also for those crazy kids who think it might be fun to lay down in the containment field.  Should this happen they will only have to endure 20 seconds of discomfort; hopefully enough for them to learn their lesson.  The system will automatically reset following its removal from the field.

Seamless Warning Tone (Anti-Linger):

Perimeter® brand dog fence systems avoid excessive battery drain.  This can happen with dogs smart enough to sit in the warning area until the receiver battery is dead.  Perimeter® software moves your dog from a warning tone to a low level of correction 1 second after entering the warning tone area. This avoids premature battery drain as well as to help promote the seriousness of their boundary.  You should not allowing your dog to spend excessive amounts of time in the warning tone area. This will condition them to not take the fence as seriously as they should.  Additional time in the warning area will promote testing the fence more frequently causing shorter battery life.
