Versatile installation

A single Flex™ camera can replace multiple single-sensor cameras with great ROI. With a variety of lens arrangements and positioning, the camera can enhance any application and cover any area needed with no blind spots.

Magnetic track flexibility

The camera's unique magnetic track allows four individual lens modules to be placed in almost any possible configuration. A fifth, vertical, top view position in the center of the camera offers complete coverage and field of view control.

4x vari-focal lenses with motorized zoom and auto-focus

Adjust the camera’s four (4) individual vari-focal lens modules to achieve the ideal field of view based on your unique needs.

Easy camera installation

The camera includes a simple double-lock mechanizsm between the camera and mounting accessory, making installation quicker, simpler and faster.

Wide tilting angle

Each lens module has a total tilt angle of up to 80°, thanks to the modules' aspherical hemispheric surface. This reduces blind spots in the camera's foreground.

IVA Analytics

MEGApix IVA cameras have a powerful engine to detect and classify people and vehicles in real-time. IVA+ license upgrade offers advanced video content analysis detection capabilities.
