The Mini Wireless Cam Finder locks onto any wireless camera transmission quickly and easily finding single or multiple hidden wireless cameras and lets you see what they see. The 2.5" color TFT high resolution monitor displays the video image while the LCD window shows the exact frequency of transmission. Automatically scans all the commonly used video frequencies in less than 5 seconds and "locks-in" on any video camera transmitter and sounds an audible alert tone. Selectable antenna sensitivity allows "lock-in" on sources up to 500 of feet away (depending on power of source transmitter). Durable all metal case.
