Spy Camera Frequencies

Wireless spy cameras are the most popular hidden camera used in covert home surveillance.  As of 2010, wireless spy cameras operate within a range of frequencies: 434mhz, 900mhz, 1.2ghz, 2.4ghz and 5.8ghz.  Wireless surveillance methods are ever improving.  The expectation in the future is that wireless spy camera will operate at even higher frequencies, improving range and video quality.  The wireless spy camera still remains the leader for homeowners and as the technology improves so will its popularity.

900mhz – 1.2ghz spy cameras are still for sale but are considered lower quality and out dated.

The most popular frequency used is 2.4ghz because of the quality and value it brings.  Spy cameras that use 2.4ghz could be sensitive to signal corruption. Signal corruption (noise) happens when two or more devises share the same band.  Common household items that may use the 2.4ghz frequency are microwaves, garage door openers, and cordless phones.  Signal corruption is a small concern and should be considered, but is not as common as you might think.

5.8ghz spy cameras are growing in popularity because consumers desire the reduced risk of signal corruption and the range 5.8ghz offers.  Wireless camera range varies greatly in real-world applications.  Manufactures assume a clear line-of-sight(LOS), but in most home applications there are doors, walls, and other obstructions that will affect the signal.  5.8ghz spy cameras offers a greater range for real world applications.
