Frequently Asked Questions

  • Is the Nor1545 suitable for permanent outdoor installation?
    Yes. The IP65/66-rated enclosure is designed for long-term unattended outdoor deployment in temperatures from -25 degrees C to +55 degrees C. This makes it fully capable of withstanding the extreme summer heat in Saudi Arabia, the UAE, and other GCC countries.
  • Can I access monitoring data remotely?
    Yes. Built-in 4G LTE and WLAN enable secure remote access through the NorCloud platform. You can view live data, configure alarm thresholds, retrieve historical measurements, and manage multiple terminals from anywhere with an internet connection.
  • What power options are available?
    The Nor1545 supports mains power, battery backup for uninterrupted operation during power outages, and solar power for remote installations without grid access. The solar option is particularly valuable for monitoring sites in remote desert locations across the GCC.
