Vision AI ASIC enables always-on vehicle security
Omnivision’s OAX7700 ultra-low-power ASIC is an always-on vision AI companion processor for vehicle security systems, supporting sensor resolutions up to 720p. An integrated neural processing unit (NPU) allows designers to develop custom algorithms for human presence detection, object classification, and distance measurement. The ASIC can upgrade existing exterior camera solutions, such as surround-view systems and edge AI-based parking surveillance systems.
In always-on mode, the camera continuously monitors the vehicle’s surroundings, consuming minimal power until an event triggers it to switch to normal mode. It records up to 10 seconds of pre-roll video that the ECU analyzes to validate the trigger before activating an alarm, if required. This helps the system avoid false triggers from wind, birds, or other non-threatening motion.
According to Omnivision, parking surveillance systems equipped with the OAX7700 ASIC consume 97% less power than existing solutions. The chip also reduces the processing burden on the central compute platform, enabling more efficient decision-making at the edge.
The OAX7700 integrates stacked PSRAM and flash memory in its 60-pin BGA package. Samples are available now, with production scheduled for the first quarter of 2027.
