I have always wanted to buy a cat m1 gps tracker, but there are many styles and models on the market, and I am not very familiar with their performance and use methods. I do not know which one is more convenient to use, more durable, and has better performance, so this idea has been hanging there. This time by a friend introduced with this Heze Zhiren A5C, feel good. Now let's talk about how I use it. A5C operating voltage 3V, working current 60-80ma, standby current is less than 1.5μa (the reason why the super long standby probably has a lot to do with the small standby current). Black and gray, from the appearance looks a bit like military products as very thick and solid, the following use of a pull-type bottom cover, the bottom cover above the magnet, the total weight of the machine is about 100 grams, held in the hand slightly has a certain sense of weight. Randomly send three CR123A batteries, there are many sellers online to sell such batteries, about 10 yuan, battery replacement and supply should not be a problem, the price is acceptable. The machine has a light-sensitive anti-demolition alarm function, and if it is taken down or dismantled by others after installation, it will have an alarm display. This should be the light sensing element, and there is also a small opening corresponding to the element at the bottom of the housing. Before installing the battery, you can see that the internal structure is relatively compact, and the circuit board is relatively fine. Found a USB port, I do not know if it is for the future upgrade of the data line, go back and continue to understand. Before installation, we must first prepare a card with traffic, there are generally two kinds, one is with traffic can not call the Internet of Things card; The other is a card from several telecom carriers, which can make phone calls and have traffic to surf the Internet. I do the secondary card, use the main card traffic, as for the phone function can be ignored, do not need. Use a small Phillips screwdriver to open the cover of the machine, first put the card into the card sleeve of the machine, and then install the three batteries according to the positive and negative poles, at this time, the small indicator light on the main board of the machine flashes, indicating that the machine has begun to work, and then cover. Find a safe place in the car that is not suitable to be found and does not affect the driving.
To log in to the vehicle monitoring system or mobile APP, enter the user name and password (to contact the after-sales staff to obtain). After logging in successfully, change your information, and then you can find the location of your car, done! Now I basically have to check the machine return information on time every day, the little guy is very disciplined every time to report the location of the vehicle on time, never lazy. The positioning accuracy is sometimes more than 10 meters, sometimes dozens of meters, in general, it is acceptable. There are three sending modes: (1) Alarm clock, which sends back information 1-4 times a day like an alarm clock; (2) Timing mode, that is, return information every few minutes, 0-999 arbitrary Settings; (3) Weekly mode, which refers to the time of the day of the week to return information once. I'm using alarm mode. Summary: The most satisfactory point is the design of the power supply, which is very energy-saving, and basically does not need to be installed for one or two years at a time. At present, I have been using it for more than a week, and the electricity has just changed from 99% when installed to 97%. I use about 1% more electricity for more than a week, and it is absolutely no problem to change the battery after a year and a half.
