On Sep. 2017, Ecuador president accuses predecessor of planting spy camera. More details, please check https://goo.gl/J5ciWY
The hidden camera was found on Sep. 14. 2017 when staffer noticed that the wall in which it was hidden was heating up. According to the news, the spy camera had been monitored remotely by former President on his cellphone.
Analog Camera does not support view remotely on the smartphone, supposed they are using Wi-Fi, 3G or 4G camera as a spy camera, to do the real-time wireless remote monitoring.
Wireless camera temperature goes high when it starts to transmit video signal but it is not the best way to detect the 3G/4G wireless spy bug.
Wideband frequency detector, 3G/4G signal detector, and RF detector are the better choice.
The advantageof the professional 4G phone detector, most of the mobile phone detector is working as "scanner" so it may not be able to detect each message.
First you need to understand that while you are sending data or browsing the web the connections done through 4G, otherwise it goes on 2G or, in certain cases, 3G (voice call). If the user is not talking continuously, the phone pause transmission.
The professional 4G mobile phone detector is designed to capture the spontaneous 4G signal and create a short beep to aware the user that there is a 4G link. But it can not be used to capture the caller unless who is making a voice call. Because 4G is sending packet data in short burst sporadically. So, you won’t expect a steady signal strength bar continuously. And the voice call is “jumping” through 2G or 3G depending on the local traffic.
The other problem related is: the signal strength is not a constant due to Fading”phenomena. The ideal testing condition is linear.
RFD-10 with the non-linear sensitivity adjustment software and it is for those users looking for maximum detection distance and catching instance signals. It is very effective in catching people sending short messages.
