For the security purpose of pets, dog watch invisible fence is used. This is a hidden fencing system. These security systems keep the pets inside the boundaries of home. Both of these systems work with the help of transmitter and receiver collar. A person should check all the differences between both security systems and then buy them according to their pocket and facility.

In the systems of dog watch invisible fence, the purpose of the 'Dog Watch' is to keep the dog inside the limits or boundaries of home, without having fences or dog pens. It is used in a way that the wires are fixed inside the surface, around the required parameter and a collar is used for identifying the position of dog when he gets near to the wires. Whenever this situation rises, the wire gives a low shock to the dog, called as correction. This shock motivates it to return into the boundary. Due to this the dog does not tries to cross the wired area.

The second security system of dog watch invisible fence is the invisible fencing. It works for the same purpose, as achieved by the dogwatch. This type of fencing can be set even when there is an installation of any other type of fencing in the same area. This is not only for installing under the ground, but also on the outer boundaries.

There are many features of dog watch invisible fence. The dogwatches fences are fixed under the ground and cover only a small area of 200 acres. This system prohibits the entrance of pets, within a specific area of property. It prevents the entrance of pets inside a specific area, which is secured by a person as a prohibited area for dog. The design of invisible fence is made for the same security purpose, but the difference between both is that the attachment of invisible fencing could be adjusted with the outer fencing, but the dogwatch is fixed inside the surface of ground.

The invisible fence transmitter collars are digital & customized for dog. This security system has both audio & video systems for warnings, to give information about the operations of transmitter. In this, the changes in the levels of correction can also be made according to requirement. The level of correction can be changed for inside, higher or lower than outside. One can change the correction mode to the tone mode, which proves to be gentler to the dog, during the time when someone trains his dog or any other pet.

The dogwatch transmitter works on the principles of 'FM' technology as it keeps the signal secure from breaking, due to any outer interference. There are 20 levels of correction in dogwatch system. With the help of this, one can set the level of correction according to its desire. There is one more setting in it, which named as 'audible only'. This setting warms up the dog before giving it correction. There is a facility of alarms, through which the owner of the dog can know about various changes in the strength of wire. It also alerts when the boundary wire is broken.
