Trackers are often used to protect property. To make the protected objects more secure, Tracker is often hidden so that others cannot easily find it. The tracker must not be too large, otherwise it will not be easy to hide.
In addition to size, I also want to show you some types and methods of communication with trackers.
Some GPS devices are bulky, and some can be as small as buttons. The size of these devices is also related to the power supply.
Every device must have electricity to work. There are two common types of power: batteries and hard-wired. Many devices have built-in batteries, which vary in size, the smallest being as small as rice grains. In general, the smaller the battery, the less power the device needs to perform its required operations.
The equipment that needs to be wired is to connect it to an external power source. This device can be used in scenarios that need long-term vehicle tracking. Even if the external power is disconnected for a short time, the device may have a small backup battery built in for short-term work.
There are two common techniques used by tracking devices to locate objects. One is GPS technology. A satellite system orbiting the earth can provide accurate position information. This technique is currently more commonly used. But when the service is provided inside the building, it will be obscured by signals and the information sent will be less accurate.
The other is a base station tower. Some trackers rely on base stations to work. The device must be relatively close to the base station to see its location information. It may not be as accurate as GPS, but it requires less power.
Once the tracker is powered up and functioning, it transmits location information to the device owner. The transmission methods are mainly three types: cellular network, satellite and WiFi. Today’s cellular networks exist almost everywhere. Very few remote areas have no signal.
And satellite cellular services can provide services even in the desert. But it’s expensive. WiFi transmission is suitable for deep inside buildings. The cellular signal in the building may be too weak to be used. And using WiFi to communicate can solve this problem.
Do you know some of the above trackers?
