How safe is your home from malicious intruders like burglars and robbers? If you think that you can protect your family from these miscreants simply by locking the main gate, then you are definitely wrong. In fact, even the most petty thieves these days carry some sort of equipment to help them slice through locks. Besides, there is always a back door with a malfunctioning lock, a balcony partly hidden by trees in your garden, or a cellar door that opens into your backyard. Burglars will certainly case your home before they try to break in, and are very likely to exploit such alternative entrances.
