Secure and private

Footage is stored locally for easier compliance with data protection regulations and further protected from unauthorized access with industry-standard AES-256 encryption.

Assisted mass deployment

Automatically locate new cameras within a set IP range, and configure units in batch via spreadsheet import or replicating settings to new cameras.

Centralized management and monitoring

Stay on top of your deployment by previewing triggered events directly on multi-floor or multi-location maps, with online map integration for Google Maps and OpenStreetMap.

Video analytics

Take advantage of intelligent monitoring features such as motion detection, no idle zone, foreign object detection, and anomaly detection to cater the most common surveillance scenarios.
