First, anti-theft alarm system with the original installation, but also led to problems with the vehicle circuit;

If your car is equipped with the factory original anti-theft device, then do not post installed, and money is not that also a security risk and can even lead to spontaneous combustion vehicles.

Point of concern: Some cars equipped with factory anti-theft devices, but if you have installed anti-theft device after words will affect the use of the original vehicle anti-theft device, or affect the use of other electronic devices of the original car. If you are unsure whether your car is factory installed anti-theft devices, it does not matter, look at the configuration list, or call 400 and ask to see the vehicle body is not related identity clear.

Second, too much power, leading to battery power loss could not beat the car;

Take a look at your battery capacity and then install anti-theft devices, some domestic car battery capacity is relatively small, but the vehicle itself has a lot of parts need to stop when powered by a battery, our burglar alarm when it is played in the parking Great features. In simple terms, after it turned out that the small-capacity battery to power the car 10 can sustain 30 days of uninterruptible power, and power consumption is relatively large installed anti-theft alarm, the batteries can only provide a 10-day power supply. So for some small-capacity battery car, after the installation of anti-theft alarm often face is no electricity, but the battery is often the greatest damage in loss of state power, which reduces battery life.

For the battery capacity is less than 40Ah battery capacity is small you can still install burglar alarms, car less if your usual time, recommends weekly car engine to run a few kilometers to the car enrich my knowledge, avoid the installation of anti-theft alarm increased electricity consumption so that battery power too quickly without affecting your car.

Thirdly, the alarm sensitivity is too high or too low, little sign of trouble alarm, or is not an alarm;

Burglar alarm sensor sensitivity of your choice must be accurate and controllable. With the New Year's Eve firecrackers sounded sounds together there one after another vehicle anti-theft alarm, and have to say that these alarms do work, it can cause any trouble, "alert", but this is too unprofessional should not ring when loud, but in everyday life just a little bigger sound or vibration, can make this point for 24 hours post employees enjoy working for fear of his master does not know it's hard work in it. And it's doing is it not "crying wolf story" reality version of it. What are the benefits always barking, get the battery out of power, the owner have to curse your meal, which is why it, thankless.

We choose to install anti-theft alarm when we must choose to adjust the sensitivity of the product, so that in the Spring Festival this particular case, we can reduce the sensitivity of the protection of our batteries. In normal days, the sensitivity can be adjusted to be in, both play a role in the protection of vehicle safety is still not a nuisance.

Digression: To share that burglar alarm sensors mounted on the vehicle body, there is no sensor on the rim, so it can not protect the rim stolen, which would explain why many of my friends obviously installed a burglar alarm It is still the thief stole the tires.

Fourth, to buy a cottage products encounter problems during installation and use

Quality car alarm to buy must be guaranteed, not only refers to the quality is the quality of the quality of products as well as installation.

As to choose what brand, you can ask your friends around the car to see what brand they use the product. In the installation, it is recommended to the 4S shop installation, after moving to the electrical thing or professional people to do better.
