No profession stands to benefit more from the use of on-body wearable cameras than law enforcement. Video surveillance of police activity from an officer’s point of view can serve as invaluable—and often indisputable—evidence inside a courtroom.

Cameras worn by police officers have demanding engineering requirements. They must be lightweight, operate for hours on a single charge, and generate crisp, clean imagery in a variety of challenging scenarios. Ambarella’s body-worn police camera solutions meet these demands by offering superior low-light performance, HD streaming capability, ultra-low power operation, and incredible responsiveness, transitioning from a powered-off state to an image-capture state in under a second.

On-body wearable cameras are becoming increasingly common among consumers as well. Whether used for life-logging, enhanced personal security, or simply more convenient video capture capabilities, these consumer cameras require high-quality video with sophisticated image stabilization, Wi-Fi support for instant sharing on social websites, low power consumption, and form-factors that are both minimalist and attractive.

Ambarella's consumer camera designs meet this challenging set of requirements by providing developers with a best-in-class combination of feature-rich image processing features, highly efficient video encoding, and a low-power architecture designed expressly for the wearable use case.


Ambarella A7LW - Wearable Camera SoC

The A7LW wearable camera SOC simultaneously captures full HD video while streaming a second mobile-resolution live video over a Wi-Fi network, all of which can be controlled wirelessly from a smartphone or other remote device. Best-in-class image signal processing engine, temporal 3D noise filtering and breakthrough 3D electronic image stabilization provide exceptional video quality even in challenging conditions.

Ambarella A12 - Police Wearable Reference Kit

The A12 Police Wearable Reference Kit enables the fast development of a next generation, on-body wearable camera for police and security markets. Two lens-sensor modules are present on the compact, body-worn design. One camera module is integrated into the main unit and is capable of Quad HD at 15 fps encoding, with the other connected externally via a one-meter cable and supporting encode up to 1080p30 resolution.

In addition to a powerful ARM Cortex-A9 processor, the solution offers a rich set of peripherals including two USB instantiations. One USB 2.0 host is used for connection to the 4G/LTE module with a second USB 2.0 acting as a device to enable the kit to be identified as a mass storage device when connected to a PC or docking station.

The ultra-low power Ambarella A12 is designed for long operation and transitions from a powered-off state to a fully functional state, capturing video or still images, in under one second. The A12 has superior low-light performance and overall image quality. Additionally, the device is capable of encoding and outputting a second 720p30 stream, making it well suited to streaming applications.
