The tiny IDS SQ-NLM saves on wall space and wiring, while its mic can be positioned exactly where you want it, receiving true exposure to sound levels anywhere over your IDS network. Use IDS Core to configure up to 100 audio thresholds, triggering warnings, reducing volume and complying with latest health and safety legislation.

The compact device is housed in a rugged aluminium enclosure, making it ideal for applications with little space. It connects to your network via Ethernet and, with its combination of PoE and tiny size, can be installed quickly and discreetly.

Setup and management of the unit is straightforward, using the Windows based configurarion software supplied. It supports DCHP for automatic acquisition of IP address, but can be configured manually for a static IP if required.

Firmware updates will be available via our website.
