Anyone around here into drones and FPV? The hobby has really taken off in recent years and you can find drones with FPV capabilities for little money. A typical setup uses two radios: a 2.4GHz radio for the control signal and a 5.8GHz radio for the FPV video feed. The video is analog, the same kind of standard definition composite video those X10 2.4GHz wireless cameras used to use in the early 2000s. This is great because digital video presents several problems for flyers when used at long distances with lots of obstructions in the environment such as trees and buildings. Digital video will break up more easily, blank out entirely at times, and introduces a delay when flying which affects your reaction time, especially if you're using a racing drone. Analog video is generally more reliable because even if the picture breaks up you can often still make out where your drone is going even if you lose color and have a bit of snow in the picture. It's the same concept as analog TV vs the new digital system and its digital cliff effect when trying to watch a weak station. When a storm comes through your area which would you prefer to have to watch the weather report?
Most people don't care to have HD video on their drones. You can get analog 5.8GHz transmitters and receivers for as little as $15 each. You can buy all kinds of transmitter power levels, antennas, multi-antenna receivers, and auto-scanning receivers. The FPV side of flying has become kind of a science in its own right. So what is warspying? Warspying is buying a wireless video receiver/screen and driving/riding around town searching for wireless video cameras and video senders. Like the old X10 cameras the video technology used by 5.8GHz drones is unsecured and unscrambled. Any 5.8GHz analog video equipment designed for the consumer market is cross compatible with drone FPV equipment. This means you can buy advanced FPV antennas and receivers and use them to hunt for signals around town or your neighborhood. It also means if someone is sending their cable box over a wireless link and a drone flies by there's a chance it will interfere with that signal.
There's a growing discussion thread on radioreference.com on the return of warspying on 5.8GHz. Seems a lot of people who are interested in doing this didn't realize the drone FPV equipment is cross compatible with other 5.8GHz video equipment. This also includes wireless backup cameras, trailer hitch cameras, and certain spy cameras. And this activity is not illegal since the signals are unsecured and they are entering your personal space, just don't record any of them.
Who's interested in a fun drone FPV and/or warspying discussion?
