In China, with the huge profits of the domestic auto market and the high-tech veil of satellite positioning, the brand of vehicle gps tracking devices has been increasing in the market. At the same time, there are also a large number of enterprises that do not have the qualifications for production and R&D, which have led to a large number of brands in the market, and the quality is uneven, which brings great inconvenience to consumers. So how do you buy a vehicle gps tracking device correctly? Great-will is a high-tech enterprise specialized in vehicle gps tracking devices. Let us answer it for you.
When purchasing vehicle gps tracking devices, we must first know what basic functions the product should have:
(1) Global satellite positioning. It can be positioned by loading the mobile phone cartoon power, and there is no dead angle in all-round positioning tracking. It can be positioned and tracked regardless of time, regardless of time. It is equipped with multiple sets of map correction errors, and the operation is simple and easy to use. (2) Driving track playback query. The owner can select the driving trajectory of the last 120 days. During the playback, the speed, direction and dwell time of the time can be displayed. The playback is smooth and intuitive. (3) Equipped with Android/Apple mobile client. Simply download the client installation to the phone, you can query the vehicle location, playback track, real-time tracking, support satellite image browsing, and make the map browsing more realistic. (4) High-end positioning chip, the chip of the positioning system is the core component. The advantage of the high-end chip is fast, sensitive and power-saving. The actual test shows that it takes only about 30 seconds from power-on to full positioning. Generally inferior products will use cheap and inferior chips. Such chip positioning is often inaccurate and the error is too large. (5) With intelligent intelligent electronic fence, intelligent automatic fortification can be SMS reminder. After the vehicle enters the fence, it will automatically enter the fortified state. After the vehicle is out of the fence, the owner's mobile phone will receive an alarm message prompt, and it will be permanently valid without repeated settings.
After understanding the function of vehicle gps tracking devices, we can explain the following aspects:
1, positioning accuracy
Many people will care about the positioning accuracy of the device when they choose the vehicle gps tracking devices, but in fact, we don't have to care too much, because the global positioning system is based on the release of time data, plus the constant synchronization of satellite position data, the receiver calculates after receiving. Come, and the chip part is like the same chip we used to say that most of the products are used, and the calculation part is not which manufacturer can control it at will. The influence of positioning accuracy is mainly due to the stable reception of satellite signals. After continuously calculating the time data sent back by the satellite, it can be accurately located, but if the signal is lost, the positioning accuracy will be very large. ups and downs.
2, positioning communication module
For the current positioning products, there are only two types of positioning, gps positioning and Beidou positioning. Both positioning modes have advantages, and the positioning accuracy is not far behind. For the moment, due to the small number of satellites visible in the Beidou, The satellites are poorly distributed, and the positioning accuracy is poor or cannot be located. However, many products on the market now support dual-mode positioning of GPS positioning and Beidou positioning, so this is not too much to consider. As for the communication module, the product has a strong ability to receive signals, otherwise it is impossible to find the signal at all.
3, product stability
The stability of vehicle gps tracking devices is definitely to be considered. It is the first choice for anti-electromagnetic interference and stable performance. When the vehicle is bumpy, the temperature is high, there is electromagnetic interference, and the environment inside the car is relatively poor, it will affect the operation of the product, so the stability of the product should be emphasized. The advantage of satellite positioning terminals currently on the market is that it can capture and track signals and reduce signal interference caused by high-rise buildings in the case of occlusion and bad weather conditions. In addition, the stability is also directly related to the fast and accurate calculation of the path.
4. Service operator
Choosing a company product with its own software monitoring platform, software upgrades and additional functions of the product are also worth considering. The selection of the brand is actually after the sale. For satellite positioning products, the subsequent service issues are more important. Different manufacturers are free. There are also a variety of software updates. Knowing when you buy it can avoid unnecessary troubles after use. Good after-sales service not only guarantees the use of the products, but also allows consumers to buy a comfortable and practical. The purchase of a large brand of products is not only guaranteed by its own quality, but also can enjoy a free upgrade service for a certain period of time.
5, the size of the appearance
Many people may think that the appearance of vehicle gps tracking devices is not important, they are almost the same, but they are also tricky. Since the vehicle positioning terminal is generally concealed, this requires that the equipment be small and hidden anywhere, preferably without wiring. The vehicle positioning terminal produced by Boschian has built-in antenna type, strong magnetic adsorption-free installation type, and long standby type, which can fully meet the various requirements of customers.
Vehicle gps tracking devices require small size, easy to install, good stability and anti-interference ability. The best manufacturers have their own software monitoring platform, good after-sales service, and can continuously update and upgrade software. In addition, we must know that when choosing a product, it is not the function as full as possible. It is rather fancy and not practical. When purchasing a positioning terminal, we must first know what function it needs most, and it is a basic positioning tracking type. Video surveillance is still anti-theft or other. It is much better to choose the corresponding product after determining the function you want. It is better to know that the simple locator will be more stable than the all-purpose vehicle gps tracking devices.
