SentryChroma comprises of a three Megapixel colour camera mounted with SentryScope viewing the same wide 90° area. The two image streams run simultaneously over separate Ethernet connections to a single SentryServer for storage and review. Clicking an icon switches from one surveillance record to the other, displaying the corresponding video from the same time and location. Complex events can be quickly analysed in ultra-high-resolution or in colour at a fast frame rate. SentryChroma can be added to new or existing SentryScope installations.
