Vehicle Jammer Detector

Selective jammer detection for cars, vans, hgvs, plant and high-value assets. Designed to detect abnormal in-band RF conditions rather than simply respond to every nearby RF transmitter.

Vehicle Guard JVD-400 GNSS and cellular jammer detector

Production image will be added when the prototype enclosure is complete.

Need dedicated satellite-navigation monitoring rather than combined vehicle coverage? See the GPS Jammer Detector range.

  • Passive receive-only
Band-selective detection: ordinary broadband RF detectors can alarm on legitimate phones, radios and wireless devices. Vehicle Guard restricts detection to the relevant service bands. An alarm indicates an abnormal in-band RF condition; further investigation may be needed to establish the source and intent.
