Car alarm is the protector of the car, by the car anti-theft devices and circuits are mated together, which can reach to prevent theft of vehicles, have been violated, protect the vehicle and achieve the purpose of anti-theft devices various functions.

Q: There are various brands of anti-theft devices different?

A: The various brands of anti-theft devices have a lot different from the principles of design, component selection, processing and alarm functions design. It is because of these differences, determine the anti-theft device reliability, lifetime performance and price vary.

From the principles of design such as:

(1) whether to adopt the FR4 double panel design, its advantages are:
① Component solid solder joint, anti-theft devices for vibration resistance, anti-theft device is installed in the vibration, bumps in the car for a day, vibration and strong extend its service life.
② alarm host small, easy to hide installation.

(2) whether to adopt a multi-circuit protection system, the advantage can be adapted to a wider range of battery voltage changes, not because the battery voltage is too low, causing panic alarm host microcomputer, and anti-interference ability.

From the choice of components such as:

(1) whether the use of microcomputer is a long time in the memory IC.

(2) whether more use of SMD components.

(3) whether the use of components having good heat resistance and pressure resistance.

Q: The correct choice of alarm installers is very important?

A: This is really important!

Car alarm good and bad, mainly by three factors: the quality of security products, security installation methods and the proper use of anti-theft. The alarm installation method is one of the anti-theft device quality is also an important factor, and losses due to poor installation of anti-theft device is caused by heavy, such as car computer crash, the airbag blasted, burned cars and other circuit components damage, which certainly are due to improper installation. So, choose a good, experienced installer is the basic guarantee of your car is very important.

Q: How to choose alarm installers?

A: Experienced car alarm installers not only for anti-theft devices have a comprehensive understanding, but more important is to be on the car circuit is very familiar with and understand, they judge the car circuit is not by rote, but by circuit theory. Especially in the present era, the upgrading of the car faster and faster, it is only by knowledge of the circuit in order to properly determine vehicle lines. Be aware of the following when selecting alarm installers:

(1) whether the anti-theft device which stores operating, installation qualification, including business license qualifications and public security organs and the like.

(2) sales indicate whether the alarm origin, this is your alarm service and the availability of basic security in the future fault warranty.

(3) whether to hold its store anti-theft device manufacturer's authorization, which indicates whether the store brand of this alarm have a more comprehensive understanding of, and has been recognized by manufacturers and installation training.

(4) anti-theft devices installed, be sure to ask the manufacturer stamped seal installers and telephone alarm warranty card.
