Locksmiths can provide their clients with mechanical protections as well as electrical ones. Professional locksmiths make it is easy by making the turn of your property count all the possible accesses and determine the weak points of them:
a play in a frame can facilitate the introduction of tools;
the cylinder of the lock of a door which exceeds outside can be forced (remedies easily: to reduce the length of the cylinder or to place a rosette fixed by the interior to prevent which it can be clutched with a grip);
a door whose locking is light (the addition of an interior bolt can prove extremely useful);
the old latches with vertical operation are easy to open (there exists in the trade of the devices with lock making it possible to block these latches);
be wary of the small windows because they are in general easier to force or break;
Often, if the intruder breaks a pane, it is in the intention to operate the latch. It is thus not useless to consider the installation of latches provided with locks, especially if your windows are not provided with double glazing and/or safety glass;
attention with the ventilators;
Not to neglect either: intrusions by the roof (snuffboxes).
Very often, even if the small precautions that are named above are applied and that one has effective mechanical protections, our properties are not safe from increasingly daring burglars any more. One will be able to choose then the installation of a system of detection of intrusion. This one will decrease the flights risks appreciably. Caution: The system of detection of intrusion does not replace mechanical protections or measurements it supplements them. If you carry out an effective protection electronic, but that you leave your fortune well in sight with range of the hand and that you do not close your main door, it will be enough to a few seconds to an individual to penetrate in your dwelling and to carry what interests it. Electronic protection will then have been used for nothing.
Locksmiths will advice you on a system of detecting intrusion. The system of detection of intrusion is generally composed of detectors, indications and control devices. The unit is managed by a power station which ensures the bond between each element of the system and which allows electric network connection and possibly with the phone network. Before 1990, the profession was governed by no law. Consequently, the procedure of installation of the systems of detection of intrusion was left at the discretion of the fitter. Being given that no matter who could of the day at the following day say fitter, there obviously were failures. Many installations were not carried out correctly and the reputation of the profession felt some. But the primary reason for which one legislated on the matter, it is to limit the number of false harmful alarms for the vicinity. Consequently occasion, the legislator laid down rules of good practice in order to guarantee to the user who the system which it buys is reliable and functional. It also envisaged conditions of use to which the user of an installation of detection of intrusion must conform.
