VideoIQ Logo VideoIQ Inc.
213 Burlington Road, Bedford, MA
VideoIQ was formed out of a product group in General Electric, to exploit the digital video analytics algorithms developed by Mahesh Saptharishi and Aleksey Lipchin for real-time video surveillance and threat detection.  The deployed products include standard-definition (SD) video cameras with embedded video analytics and local video data storage, analog-input SD encoders with the same capabilities, high-definition (HD) video cameras with similar analytics, internal storage, motorized focus and a remote pan-tilt-zoom (PTZ) option.  All of the products have audio input, audio output, contact-closure alarm inputs, alarm signal outputs and a C-type alarm relay.

The Rialto product family that I worked on included standalone and rackable multi-channel encoders with multiple channels of analog SD video or digital video via IP, SD and/or HD.
