Lojack Detector

Actively Discover Illegal Jamming Devices Recent years have seen a significant rise in the use and availability of illegal jamming devices. These devices are used to defeat surveillance and security equipment including cellular devices (audio/video), GPS, and Lojack tracking. While jamming of signals is itself illegal in most countries, identifying when a jammer is in use has always been difficult. The J-ALERT makes jammer detection and tracking easy, safe, and cost effective. The J-ALERT is an RF signal analyzer that monitors Cellular Radio Frequencies, GPS, and Lojack to determine if the target is actively jamming these signals. When the J-ALERT detects jamming in the cellular bands a corresponding LED will light to indicate the Received Signal Strength (RSSI) of the jammer and which band is being jammed. When GPS L1 frequency and a cellular band or Lojack is being jammed a bar graph indication of jammer received signal strength (RSSI) from the jammer is displayed, enabling tracking. If both a cellular band and GPS L1 are being jammed simultaneously or if Lojack is being jammed a beep will sound every 3 sec. to alert the operator a jammer is in use. The J-ALERT also has a stereo jack on the back of the unit with both N/O and N/C contacts for triggering an external device on alerts.
