What they do

Problem

Organizations with existing security cameras lack reliable, scalable intelligence to detect and respond to incidents without expensive hardware replacement.

Solution

Who it's for

Businesses and organizations operating facilities with legacy security camera systems such as retailers and other multi-site operators.
