Digital Surveillance Camera


Digital Surveillance cameras


Since the appearance of network cameras that can communicate data via the Internet and due to the growing awareness of security, the market for digital surveillance cameras has rapidly expanded to include applications such as remote surveillance in factories and warehouses in addition to crime prevention. Functions for correcting the brightness of an image according to conditions such as indoor/outdoor and daytime/nighttime, and functions for detecting movement, are digitalized and are becoming increasingly sophisticated. Digital surveillance cameras will continue to demand higher resolution and more sophisticated functionality in the future.

Renesas responds to these requirements with the SH-Mobile R2R with built-in high-function image processing engine, Rx6xN LAN controller, SH-Ether, SLP (Super Low Power) Series microcontrollers, and 78K0R/Lx3, as well as motor driver ICs and various other devices, providing optimal solutions for digital surveillance cameras.
