Private investigator Carrie Kerskie revealed to NBC that they are very easy to install.
“The battery life for these coat hooks, is two hours. Then, you just take it out, pop it in the computer, and you have all your images,” she says.
“It’s real simple and easy. They just walk in, hang it up, walk out, go back a few hours later and take it off.”
The warning was sent out after the hooks were initially found in some women's bathrooms in three different locations in Florida.
If you see them, simply report it to police.
