Catalytic converter thieves use internet and Wi-Fi jammers to block nearby home security cameras (like Ring, Nest, or Blink) from recording them or sending alerts.

By deploying small, illegal RF (radio frequency) jamming devices, crews temporarily disrupt local Wi-Fi, Bluetooth, and cellular signals.

This prevents wireless smart cameras and home networks from transmitting data to the cloud, essentially blinding your home security system while they cut off your converter in under 60 seconds.

LAPD, has issued warnings about sophisticated crews of thieves using Wi-Fi jammers to block security cameras while stealing catalytic converters and burglarizing vehicles.

These criminal crews use portable radio frequency jammers to flood local airwaves, effectively knocking wireless security systems (like Ring, Nest, or Blink cameras) offline. This prevents homeowners from receiving instant motion alerts or capturing video evidence of the theft while it happens.

Most portable, battery-powered jammers only work within a range of 15 to 30 feet. The thieves must be physically close to your home or vehicle for the jam to succeed.
