LAPD warns residents after spike in burglaries using Wi-Fi jammers that disable security cameras, smart doorbells (www.tomshardware.com)

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.

Why did they specifically mention to "secure home DVR recorders"?

Other than potentially losing some TV or movies, is that really a big deal next to the other items they mention? It seems really odd to mention one of the least important things.

No. Think about it. Where is all the video from those cameras going? It is digital video, which the homeowner probably wants to record and playback... Many home security setups, particularly those that don't rely on a cloud service, are basically a DVR back end with a security focused UI.

All of my cameras are hard wired. It's going to take a lot of power to jam those.

You'd be surprised. A CB radio with a high wattage amplifier is enough to scramble analog hardwired cameras when its keyed up.

I regularly transmit 100 watts on HF using a dipole over my house. That's never knocked any of my IP cameras out. It's going to take more power than that, especially if you want to stay far enough away that the cameras can't get good video of you.

I'm talking semis with ~1000 watt linears. And analog hardwired cameras. I can watch it happen at work.

My cameras have antennas on them but use Ethernet.
