Even the most safe locks cannot guarantee full protection against penetration of malefactors into the dwelling. Effective solution of security concern is installation of the alarm system. It is fair both for the apartment, and for the house.
Types of alarm systems
Independent alarm systems are installed in the house and have no communication with the outside world. Usually they react to penetration attempt by loud sound of siren. Such alarm systems are inexpensive. They do not demand coordination and carrying out expensive installation works. However, the efficiency of such systems is quite doubtful. If your house is in the deserted place, then malefactors can simply not pay attention to siren.
There are systems notifying owners of the room on breaking. They work at GSM module basis. In case of penetration into the dwelling, the SMS message comes to phone of the owner or the entering call arrives. Such systems allow to learn about breaking attempt, even being in other region. Shortcoming is that the host should call independently the police, and the speed of response to such call can be insufficient.
The console system of protection is much more effective. Such alarm systems are connected to the central supervisory console on which in attempt of penetration into the house the signal will arrive. The key advantage of such systems — departure to the address where breaking, groups of immediate reaction is made. It can prevent theft and detain criminals. Usually the group arrives to object in a few minutes after receiving call. Such services are provided both the private security companies (PSC), and police. In police this type of service renders special division — the department of private security (DPS). To install the alarm system, the served OVO or PSF, it is necessary to choose the specific organization and to sign with it the contract for rendering services. Besides payment of the system and works on its installation the owner of the house or apartment has to bring monthly payment.
Installation of the alarm system
Signal transmission on the remote controller requires communication channel. Optimal solution — use of the line of the landline phone. If it is absent, apply radio channel or cellular communication. Reliability of protection depends on quantity of contours of the alarm system. The simplest option — installation of magnetic sensors (sealed-contacts) on outer door. They work on disconnection and report about opening of door. You should not forget also about possibility of penetration through windows. Especially it is relevant for owner-occupied dwelling. On windows it is necessary to put both sealed-contacts, and sensors reacting to glass dissecting. The most reliable protection is provided by the volume sensors reacting to the movement. Even if malefactors will be able to bypass sensors of opening of door or window, the detector of the movement will react inside. Choosing the alarm system, it is better to stop on models which have self-contained supply from accumulators. It will save you from false drops at blackout.
