Introduction to GPS anti-theft device
GPS anti-theft device is the most advanced anti-theft device at present, in addition to ordinary anti-theft, it can quickly track the location of the car when the car is stolen, so as to find the car. However, the price of GPS anti-theft alarm is more expensive than ordinary anti-theft alarm, and it needs to pay extra service fees, so the popularity is not high. The GSM mobile anti-theft device relies on the GSM communication network, combined with the intelligent linkage anti-theft of the mobile phone and the car. The alarm of this type of anti-theft device is not limited by distance and covers a wide network, but it needs to pay the monthly fee of the GSM number.
The principle of GPS anti-theft device
The GPS receiver device installed on the vehicle calculates the current position of the vehicle according to the received satellite information, and the communication controller extracts the required position, Speed and time information, combined with vehicle identity and other information to form data packets, and then sent to the monitoring center through the mobile operator’s GPRS network. The server of the monitoring center receives the data sent by the vehicle-mounted computer, extracts the positioning information from it, and displays it on the electronic map of the monitoring center according to the vehicle number and group number of each vehicle. The GPS positioning anti-theft device has a stronger function, which integrates almost all the anti-theft functions, and can accurately locate within 5 meters by satellite, that is, in front of the eyes. Its sensors use wireless sensors, which are difficult to destroy.
Is GPS anti-theft device useful? 01 Positioning car anti-theft system is a network anti-theft device, which is an active monitoring anti-theft device. It mainly achieves the purpose of anti-theft by locking the ignition or starting. The GPS satellite positioning system is used to provide 24-hour uninterrupted and high-precision monitoring services for the vehicle, and the status of the car is presented in real time. 02 The alarm relies on the GSM communication network, combined with the intelligent linkage anti-theft alarm of the mobile phone and the car, the alarm of this type of anti-theft device is not limited by distance and covers a wide network. When the vehicle suffers a malicious impact, is triggered by vibration, and is in a fortified state, after illegally opening the door and starting the vehicle, the mobile phone will immediately receive a vibration alarm text message. 03 Locking the power system The power system of the car is locked, and the car is set up with a secondary lock for anti-theft protection. Even if the car keys are in someone else’s hands, you can’t drive away. If the GPS anti-theft device is illegally disassembled, the power system of the vehicle will be locked immediately, and the car thief will also have no way to drive the car away. 04 Tracking the location of the vehicle After the GPS anti-theft device is illegally disassembled, it will send out an alarm message, and at the same time, it can also track and locate the car in real time. Using our GPS positioning function, we can quickly and accurately find the location of the stolen vehicle. , to assist you in recovering your vehicle.
To sum up, GPS anti-theft device can not only monitor the position of the vehicle in real time, but also can close the oil circuit, circuit and lock the doors and windows through the mobile phone, and receive the alarm text message. This is the most popular, practical and safe anti-theft device at present. system.
GPS anti-theft device purchase
Positioning accuracy
The first is the positioning accuracy. Generally, the deviation of 5~10 meters in GPS positioning is a normal phenomenon. If the positioning deviation of the product is as many as tens of meters, or even hundreds of meters, such products can be ignored.
Receive ability
GPS is actually a receiver of satellite signals. When the GPS receiver receives 3 or more satellite signals, The geodetic coordinates where the receiver is located can be calculated, and the altitude can also be calculated if 4 satellites are received.
Satellite Orbits
A total of 24 GPS satellites orbit the Earth in six orbits, 4 satellites each, 12 satellites in each hemisphere , most GPS receivers can track 8 to 12 satellites. At least 3 satellites are required when calculating coordinates.
Parallel Channels
Generally, GPS devices have 2 to 5 parallel channels to receive satellite signals, and up to 12 satellites may be visible (the average is 8 ). Most GPS receivers are of the 12-parallel channel type, which can quickly cold start and initialize satellite information, and the reception effect is better in forest areas.
Position Time
Position Time is the time it takes to determine the current position when the GPS receiver is restarted. The closer to the last positioning position, the shorter the startup time, and the cold startup time is generally longer than the hot startup time.
Brand
The brand is the guarantee of product quality. The reason why a brand can be bigger is the quality of the product. Therefore, when buying a car GPS When anti-theft device, it is best to look for a brand with a higher reputation.
GPS anti-theft device installation
There are roughly three types of car GPS anti-theft devices on the market: wiring type, OBD interface type and installation-free with strong magnetic.
The wiring type needs to be connected to the power supply line of the vehicle. Generally, it can be considered to be installed under the dashboard or under the driver’s seat. If only the positioning function is installed, the dome light, side door, tail light and many other places are also Can consider it.
The OBD interface is also very easy to install, because now there are OBD interfaces on ordinary cars, and most of them are under the steering wheel. This only needs to insert the OBD-type GPS anti-theft device into the OBD interface. The location is relatively simple.
No installation with strong magnets, this installation position is more, because this product itself has magnets, as long as there is iron, it can be installed, so it is very random, It can also be attached to the body with magnets, which allows it to be installed in unexpected places such as the chassis.
Installation method
1. If you know electricity, you can install it yourself. In fact, you only need to find the positive and negative poles of the car power supply. The negative pole is very easy to find. The place where the body is grounded is the negative pole, and the positive pole is found in the fuse box. , find near the car key switch or connect it directly to the battery;
2. It is best to connect to the normal power supply, that is, the power cord directly drawn from the car battery that is not affected by the car key switch;
3. Note that the lighted side of the GPS locator should face the sky, and the side facing the sky should not be close to metal objects to block the internal GPS antenna. It also needs to receive satellite signals 20,000 kilometers away;
4. You can also ask relevant technical personnel to install it, and the fee depends on the local situation!
Installation Precautions
1. In order to avoid damage by thieves, the location of the equipment should be concealed as much as possible;
2. Avoid placing it together with the emission source, such as wireless reversing radar, anti-theft device, and other vehicle-mounted communication equipment;
3. It can be fixed with cable ties, or pasted with wide sponge strong double-sided tape;
4. There are GSM antennas and The GPS antenna should be installed upside down (towards the sky).
Which type of car anti-theft alarm is good? Locks, brake pedal locks), wheel locks, etc., lock the control parts of the car. Through a switch control circuit in the car, the line file of the original car is changed. Lock the car start control system, lock the motor, circuit and oil circuit. The vehicle cannot be started without the chip key. The chip and the car key should be used at the same time. The purpose of anti-theft is achieved by locking the ignition or starting, and at the same time, the alarm information and the location of the alarm vehicle can be silently transmitted to the alarm center through the GPS satellite positioning system. After the whole system is turned on, if there is illegal movement, opening the door, etc., an alarm will be issued immediately, and the circuit will be cut off at the same time, so that the car is completely paralyzed. Through the uniqueness of the biometric features of the human fingerprint, the circuit, oil circuit, starting motor, etc. of the car are controlled by fingerprint identification, so as to achieve the purpose of anti-theft. The advantages are cheap and easy to install, which can deter car thieves to a certain extent, or increase the possibility of thieves being discovered. The anti-theft switch can be set in different places according to the needs, which is targeted, not easy to be found, the cost is small, and it will not be lost. The performance is good, the whole vehicle is anti-theft, and the safety is quite high. With the highest technical content and strong usability, it can monitor the position of the vehicle at any time, read the driving track, and automatically alarm. Concealed installation, complete functions, wireless remote control, easy operation and more use. High technical content, unique fingerprints, will never be lost and copied. The disadvantage is that it is more troublesome to disassemble and assemble, and you have to find a place to place it when not in use. For car thieves who understand the principle of this brand’s oil circuit, removal will be more convenient. The price is high, if the key is lost, it is more troublesome, and it may take a while to re-match. High prices, insufficient satellite coverage in some areas, and unstable GPS. The signal of the remote control is easy to be interfered, intercepted and cracked; it cannot exceed the effective distance. High-end cars are used more and are expensive.
