The Los Angeles Police Department has warned residents to be wary of thieves using technology to break into homes undetected. High-tech burglars have apparently knocked out their victims’ wireless cameras and alarms in the Los Angeles Wilshire-area neighborhoods before getting away with swag bags full of valuables. An LAPD social media post highlights the Wi-Fi jammer-supported burglaries and provides a helpful checklist of precautions residents can take.
Criminals can easily find the hardware for Wi-Fi jamming online. It can also be cheap, with prices starting from $40. However, jammers are illegal to use in the U.S.
We have previously reported on Wi-Fi jammer-assisted burglaries in Edina, Minnesota. Criminals deployed Wi-Fi jammer(s) to ensure homeowners weren’t alerted of intrusions and that incriminating video evidence wasn’t available to investigators.
The real answer is caching. Instead of writing video to the cloud live and losing all recordings during a wifi outage, it should just cash the last 30ish minutes in case of failure to connect to the cloud. Then once the connection is up again, it just uploads the cached video.
My cameras are PoE going to an NVR but you can also slap SD cards in them to record locally. I’m sure there are some wireless options out there with this feature included. Unfortunately wireless cameras have another glaring flaw in that they only record on movement and I’ve heard of so many stories where they didn’t catch any movement to start recording when something happened.
I have a few cheap cameras that can handle both WiFi and ethernet, they support an SD card, and they do continuous recording regardless of connection type.
