Easy deployment

Quickly set up your surveillance system with minimal effort.

Advanced analytics platform

Monitor and secure your premises more effectively with locally processed analytics, ensuring security and confidentiality.

Learn moreWatch video

Locate intruders that may take advantage of scarcely monitored areas, discourage loitering in sensitive spots such as driveways or parking lot entrances, and strengthen access control to your premises without maintaining dedicated staff on site.

Reduce health and safety risks by preventing overcrowding, optimize visitor flows with real-time and historical occupancy data, and ensure that only authorized personnel can access your premises.

Deep Learning NVR Series

Flexible monitoring capabilities

Leverage highly configurable options and automation features to act quickly when potentially dangerous situations arise.

Map-supported alerts

Display real-time previews of detected events on interactive multi-floor and multi-site maps supported by Google Maps and OpenStreetMap. Learn more

Automation rules

Reduce workloads by triggering responses to specific situations, such as activating recording when a microswitch detects a door is opened. Learn more

Notifications

Specify which events should trigger a notification, and whether to receive alerts by SMS, email, or push notification on mobile devices.

Comprehensive access options

Enjoy a uniform monitoring experience wherever you are and adapt your surveillance system to your needs — not the other way around.
