The car alarm How to choose?

The first, with the original anti-theft car alarm device but also to install, resulting in the vehicle circuit problems;What should I do: If your car factory with a factory anti-theft devices, then do not installed, the fee money is not that there are security risks, and can even cause the vehicle ignition.Noteworthy point: some cars factory fitted anti-theft device, but if you want after the installation of security devices will affect the use of the original vehicle anti-theft devices, or affect the use of other electronic devices in the original car. If your car you are not sure whether to install the factory car alarm does not matter, look at the configuration single call to ask 400 or take a look at the body of the vehicle is not related to the identity of clear.Second, too much power, battery power loss could not beat the car;Take a look at the capacity of your battery and then install the alarm, some car battery capacity is relatively small, while the vehicle itself, a lot of parts in the parking time by battery-powered, when the burglar car alarm in the parking of play a major function. Simply, 10 original small-capacity battery to the car power supply can be maintained 30 days of uninterrupted power, and installed the power consumption of anti-theft car alarm, the battery can only provide 10 days of the power supply. Therefore, for small-capacity battery car, install a burglar alarm are often faced with the problem is no electricity, and battery damage is often in a state of the loss of electricity, which would reduce battery life.Noteworthy point: so many useless, believe we must be more concerned about the anti-theft alarm device is installed with a small capacity battery and the car alarm continued to work under the battery what can "carry" how long. We consulted the technical manager of Changan Suzuki 4S store, he said to a remote lock your car and sound the alarm of the alarm function in Changan Suzuki Swift 1.3L model 35AH small-capacity battery to sustain the alarm state could maintain approximately one hour over 4 hours battery power is low, the vehicles can not start properly and the battery life.What should I do: the battery capacity is less than the the 40Ah small capacity battery, you can still install the burglar alarm, if your usual car less, it is recommended that your weekly car engine run a few kilometers to the car to enrich my knowledge, to avoid Because the installation of burglar alarm the increase in electricity consumption for battery too fast, no power to affect your car.Alarm sensitivity is too high or too low, a little trouble on the alarm, or is not to alarm;Your chosen anti-theft alarm sensor sensitivity must be accurate and can be controlled. New Year's Eve firecrackers sounded together there one after another vehicle alarm the alarm sounds, had said that these anti-theft devices really dedicated, and any sign of trouble can be caused by its "alert", but too unprofessional should ring when the ring, but also in everyday life just a little louder point or shake large points can make the 24 hours in the Gang's employees enjoy the work, for fear that his master did not know it is hard work. It's doing this is not the real version of "crying wolf story". What are the benefits always barking to get the battery power, owners have to call you a meal, which is why, thankless.I do: we have chosen to install the burglar car alarm to be sure to choose products that can adjust the sensitivity so that the Spring Festival this particular case, we can reduce the sensitivity to the protection of our batteries. On normal days, adjusted to the sensitivity can not only play a role to protect the safety of vehicles is still not a nuisance.Topic: to share with burglar alarm sensor installed in the body of the vehicle wheels on the sensor, so it can not protect the wheels stolen, this will also be able to explain why many of my friends obviously installed a burglar alarm The device is still a thief stole the tires.Fourth, buy a variety of problems encountered in the installation and use of cottage productsBuy car alarm quality must be guaranteed, not only refers to the quality of the quality of the product installation quality. Continue to talk about a personal experience, a rainy night in my house downstairs, a Beverly car alarm seems to be because of the rain water causes alarm failure, Walawala ring to chatter, the owner with a remote control can not control, had to let it sound chaotic, the next day to see the front windshield smashed a hole (retaliation), the car can not start because no electricity.In fact, the sad reminder of Beverly car burglar alarm quality or the quality of the installation but related anyway, to the owners added a lot of trouble, so the selection and installation is very important.What should I do: As to what brand, you can consult your car around a friend to see what brand of products, iron generals of China as a better brand. Upon installation, it is recommended to the 4S shop or repair shop to install, after all, the thing moving appliances or ask an expert to do better.
