(WXYZ) — A new warning is being issued for anyone who uses wireless security cameras like "Ring" to protect their home.A Detroit woman said her Ring camera didn't capture the moment her car was stolen from the front of her house, and one local expert said it's because crooks are becoming more tech-savvy.Those crooks can use this like a WiFi jamming device, or a deauther, which can be the size of an Apple Watch.They're also highly illegal, so jammers are more difficult to find, but a powerful jammer can prevent an entire street from recording on WiFI security cameras with the switch of a button.Burns said as technology gets cheaper, it's likely jammers will become more popular and it's important to keep people fully-informed."
