Which car alarm is best?

There is now a truly installation-free car alarm without connection to the car. It is very convenient and practical.

Those who call the police on their cell phone will know immediately, no matter where the person is, as long as there is a signal. It seems to be an anti-theft device called Baihong. I recently used it and found it very good. This is the best anti-theft device I have come across. I have searched for relevant information, take a look and see if it meets your needs.

Alarm working principle:

Using two sensors to communicate with the door, it can detect instant changes in the car (door opening and window breakage ), then activate GSM. cell phone to trigger the alarm. Therefore, notification is faster; there are no false alarms; There is no need to damage the vehicle for wiring. THEproduct can be placed in the car and it will work efficiently.

System function overview:

Using a combination of high sensitivity vibration sensor and ultrasonic sensor. These two types of sensors have different triggers for false alarms in high sensitivity states. The scientific combination of the two precisely misses the false alarm factors and can accurately capture the actual flight behavior of thieves and trigger the host's alarm. Make sure there are no false positives.

Use on-site alarm (optional to turn off) and remote alarm by calling the car owner's cell phone several times. The car owner’s cell phone may display warnings such as “vehicle alarm.” If the on-site alarm function is activated, thieves can also escape after hearing the sound.

NoneNo installation is required, just place it on the sun visor and you can use it.

It adopts carefully designed micro-power consumption circuit and has a built-in lithium battery. Can standby for more than 10 days. If necessary, replace the backup battery or use the equipped car charger to charge for two hours. .

Because the functions are simplified, practical and easy to use, it can be used very easily.

The alarm method is individual, dial the reserved number to call the police, and there will be no interference with each other.

Built-in highly sensitive microphone, it can monitor movements in the car when receiving an alarm.

When you receive the police, you can answer the call and shout on your cell phone to deter thieves and stop the theft.

At the same time as the alarm retentit, the car's oil and circuit can be cut off to stop the car, making it impossible for the thief to start the vehicle.

The difference with ordinary alarms is:

1. Existing high-end cars cannot be equipped with alarms because they would damage the wiring and computer systems, and other vehicles would also be scared. to affect the repair guarantee. And abandon the installation, and the real installation-free does not require any connection, you can buy it and use it. .

2. Generally, anti-theft devices only emit a sound on site and do not call to warn. However, the GSM alarm exceeds the space and distance limits and sends the alarm information to the car. owner as soon as possible. .

3. General anti-theft alarms use vibration sensors, which will cause false alarms if slightly affectedeated by the external environment. However, this alarm uses patented dual vibration and anti-false alarm technology. ultrasonic sensors, which rarely cause false alarms. .
