i think maybe you can get ac power adapter hidden camera

A GPS jammer is a device of a blocking global positioning system that blocks signals by operation. Jammers can operate on the same or adjacent frequency bands, thereby preventing proper reception of normal radio signals and rendering them useless.The GPS satellite is about 20,000 kilometers away from the surface of the earth, and its transmitting power is relatively low. Therefore, only a small amount of interference energy is needed on the ground to temporarily block the GPS signal. Even a small gps jammer can interfere with the signal within a blocking range of approximately 2-10 meters.

In certain security-related areas as well as military applications, they can use sophisticated techniques to reduce the effects of GPS interference. For flight engineering, a GPS antenna with obvious directional characteristics is used. Such an antenna only receives signals from the desired direction and does not receive interference signals from gps jammers on the ground.The general GPS signal blocker will only interfere with the GPS band and will not affect the operation of other electronic devices. The difference is that expensive GPS spoofing technology not only interferes with satellite signals, but also transmits data that has been processed by the other party to achieve positional concealment.

Employees are supervised: For a long time, telematics systems have become more and more convenient in fleet management.Almost all vehicles are equipped with GPS tracking devices, which can help the company to monitor the situation of employees on the vehicle in real time and record the vehicle. recording the route, monitoring the employees in the vehicle around the clock, personal freedom.Now, it is recommended not to damage the Ac Power Adapter Hidden Camera.GPS interference is an improved GPS location spoofing that sends the wrong GPS signal to the enemy by directing the wrong route.
