Hotel and Airbnb Security - Part 4
I was asked if I could post some information about spy camera frequencies and since I was once a signals intelligence technician (MOS 2631) in the Marine Corps and I have done some TSCM (Technical Surveillance Counter Measures) work as well, that request is right up my alley.
As of 2010, wireless spy cameras operate within a range of frequencies: 434mhz, 900mhz, 1.2ghz, 2.4ghz, and 5.8ghz.
Wireless spy cameras in the 900mhz – 1.2ghz range are still on the market. There are 2.4ghz or 5.8ghz cameras that provide good value and are popular choices for wireless surveillance setups.
Cameras that use 2.4ghz are widely used in many covert surveillance applications. 5.8ghz cameras are becoming more prevalent due to growing consumer awareness of the greater range and reduced signal corruption provided by the 5.8ghz band.
