On the other hand, attackers can open the gates, and then, inaccessible to prying eyes, take their time to dismantle the car for parts or neutralize its ingenious immobilizer. So to equip a car dwelling with a security system is not an unnecessary matter. And, as it turned out, not too expensive.
We tested two devices: the Altonika autonomous GSM TAVR alarm system and the network-based Lithuanian Eldes EPIR security system. The ideology of both systems is the same: an infrared motion sensor detects an attacker at the stage of opening the doors - and the garage guard sends the owner alarming SMS messages, and also makes it possible to hear on the phone what is happening in the room.
Then the differences begin. TAVR runs on batteries, which last for about a year. At the same time, you can turn on and off the protection both with the help of a special SMS message (inconvenient, since the device only listens to the air once a day), and with one of the two attached electronic keys (these are used in intercoms). The latter method forced the developers to set a delay (60 s): the owner must be given time to leave the garage or enter it, turn the electronic watchman on or off.
It would seem that an attacker, having seen the sensor, can simply break it (there is enough half a minute). It won’t help: TAVR consists of two blocks interconnected via a radio channel. The sensor immediately reports to the GSM unit (hidden in a secluded place or even outside the garage - at a distance of up to 250 m!) Of the detected movement, and if there is no hang up within a minute, an alarm will still be sent!

Eldes EPIR is controlled only from the phone, so it does not need a delay (although it is possible to set it to exit the garage). This allows you to get by with one unit, which, however, needs a power grid. The built-in backup battery supports the system for six hours, and the owner will also receive a message about the loss of the network. In addition, the more advanced watchman Eldes EPIR 868 can also work with 16 wireless sensors, sirens and additional devices located within a radius of 150 m, but this is more likely not for the garage, but for the protection of the entire summer cottage.
