ENVIROMUX-IMD-OHM Outdoor Infrared Motion Detector

The ENVIROMUX-IMD-OHM from NTI – Your Invisible Guardian for Outdoor Monitoring

In a time when server rooms and IT infrastructure are often located along building perimeters or in outdoor installations, environmental monitoring becomes a critical challenge.

The ENVIROMUX-IMD-OHM infrared motion detector from NTI solves this elegantly. Designed specifically for high outdoor installations, it features 94 precise detection zones, covering wide areas with reliable motion detection up to 12.2 meters at an 85-degree angle. Its unique pyro element detects temperature changes in moving objects with high accuracy, distinguishing real threats from harmless environmental effects like wind in bushes or sudden light shifts.

Compatible with NTI systems ENVIROMUX‑2D, ‑5D and ‑16D, the sensor is powered directly by the base unit at 12 V and 35 mA—no additional adapters or wiring clutter required. Imagine a large corporate campus where a server container is positioned at the edge: mounted at 2.5 to 3 meters, the IMD‑OHM detects unauthorized movement at night and triggers a cascade—LED flashing, e‑mail alerts, and floodlight activation—preventing break-ins that could cause costly hardware loss.

The ENVIROMUX‑IMD‑OHM combines rugged construction with reliable adaptability, making it ideal for demanding outdoor security. Rated IP54, the unit withstands rain, dust, and extreme conditions from −20 to +60 °C—perfect for all-weather environments from coastal sites to industrial zones.

Its dual conductive shielding minimizes false alarms from sunlight or car headlights, while adjustable detection modes—such as multi‑level wide coverage or “pet‑alley” operation—allow precise customization for every use case.

Included masking strips help exclude unwanted areas like walkways or trees, so only relevant spaces are monitored. Installation is simple: choose between terminal blocks with 22‑AWG cable up to 160 meters or CAT5/5e/6 with RJ45 for digital inputs. Consider a logistics center: the sensor monitors loading zones, detects unauthorized intrusions, and activates its tamper switch if the housing is opened—sending SNMP alerts to the control center so security responders act within minutes, protecting assets worth hundreds of thousands.

Seamlessly integrating into the NTI ecosystem, the ENVIROMUX‑IMD‑OHM adds an intelligent layer of outdoor intrusion prevention. Features such as summer-night compensation, enhanced temperature adjustment, and vegetation motion analysis ensure stable performance year-round. LED indicators display operational status, and the sensor requires both upper and lower detection zones to trigger an alarm—further reducing false positives. Pair it with cameras or sirens in your ENVIROMUX system to create a connected security network meeting DIN EN 50131 compliance standards.

Example from telecommunications: at a remote cell‑tower prone to vandalism, the IMD‑OHM detects human movement from its pole‑top mount, ignores animals, sends SMS alerts to operators, and activates remote recording. Sabotage events are prevented, uptime remains at 99.99 %, and service costs drop significantly.
