Signal Jammer Detector
GSM & GPS Signal Jammer Detector
A mobile phone jammer, GPS jammer or signal blocker is a device which deliberately transmits signals on the same radio frequencies as mobile phones, disrupting the communication between the phone and the cell-phone base station, effectively disabling mobile phones within the range of the jammer, preventing them from receiving signals and from transmitting them. Jammers can be used in practically any location, but are found primarily in places where a phone call would be particularly disruptive because silence is expected, such as entertainment venues. Jammers have been widely used to disruptive GPS trackers, defeat alarm systems and are used with the sole intend to commit crimes.
Jammers disrupt the operations of legitimate security applications, alarms, GPS trackers, emergency sensors, mobile phone services, the use of such blocking devices is illegal in many jurisdictions, especially without a licence. When operational, such devices also block access to emergency services
Digitpol has developed a stand-alone jammer detector for patrol and response vehicles, the detector can alert the driver when a jammer is in use within 200 meters. The jammer detector operates on 12v, 3.6v or 9v. We supply it as a product that can be operated on a battery or wired into a vehicle. The detector has optional outputs to trigger a siren or an alarm. The default configuration enables the LED to flash when a jammer is detected.
