Description and principle of operation of U-PROX PIR Cam

U-PROX PIR Cam is a combined digital, passive infrared, radio-channel detector equipped with a PIR sensor and a camera, designed to secure enclosed residential and industrial spaces.

By detecting changes in the thermal balance of the environment, it signals intrusion into the protected area and sends a photo to the U-PROX monitoring center.

The detector features a specialized lens and is intended for indoor use in areas where pets (cats, dogs, etc.) may be present. It is insensitive to movement of animals weighing up to 20 kg.

Installed indoors only, the U-PROX PIR Cam works exclusively with the U-PROX security system; integration with third-party systems is not supported.

Power

The device uses two CR123A lithium batteries, allowing it to operate for up to 3 years.

Indication in current mode

The LED indicator shows both sensor activation and data transmission status.

During communication with the monitoring center, the LEDs light in sequence:

  1. Sensor activation – Red
  2. Data transmission:
    • Green – transmission successful
    • Red – transmission failed
  3. Acknowledgment reception:
    • Green – acknowledgment received successfully
    • Red – acknowledgment failed

Steps 2 and 3 may be repeated up to three times (retransmissions at increased power).
