DET-UJ2 - Signal jammer detector for property protection with relay output NO/NC

Availability: In stock.



The DET-UJ2 signal jammer detector is a professional equipment that allows to detect interference noise before it cuts off the communication. The device is characterized by high sensitivity and detects all types of jamming of 2G / 3G / 4G / 5G mobile phone signals, GPS trackers and WiFi / Bluetooth wireless cameras. Additionally it detects the jammers operating in the frequencies of 433MHz and 868MHz on which car fobs and garage gate remote controls work. The detected jamming noise is signaled by the lamps on the front panel, the more lamps lit, the stronger the signal and the closer to the source of its generation. After detection and confirmation of jamming noise, the device activates the relay output NO / NC 1.0A to alarm system, siren or gate. The detector is completely insensitive to normal cellular and wireless transmission.

DET-UJ2 - detector of signal jammers is equipped with a retractable antenna and two knobs to adjust the sensitivity and detection range. The device can be adjusted it to all conditions and eliminate unnecessary natural noise and interference. The effective detection range is up to 100 meters depending on the strength of the jamming signal and the place of use. A finely tuned detector detects a disturbance signal far enough before it interrupts communication. The device is designed to protect facilities, buildings, parking lots and movable property against damage caused by jamming devices and can be integrated with the existing alarm system. It will be perfect as a complement to the video monitoring system.

The detector of signal jammers DET-UJ2 is very easy to use and does not require special technical knowledge. It is intended for indoor or vehicle use. It will work:

- in the garage - output connection to a deterrent lamp / siren
- in the car - connecting the output to the GPS / GSM tracking system
- in the underground or above-ground car park - integration with a gate door / siren / lamp
- in the home / apartment / warehouse / hall
- to secure monitoring composed of WiFi wireless cameras
- in ensuring the stable operation of IoT (Internet of Things) devices

Detected devices:

- 2G / 3G / 4G / 5G cell phone jammers (all communication on all bands)
- GPS / GLONASS / GALILEO tracker jammers
- WiFi / Bluetooth wireless camera jammers
- jammers of key fobs, car and gate remote controls operating at 433MHz / 868MHz frequencies
