Development of Video Surveillance System in All-Black Environment Based on Infrared Laser Light

Abstract

During the night or in a dark environment, the definition of current video surveillance systems is very poor, mainly due to the insufficient brightness. Although the infrared LED lights can effectively improve the quality of the picture, the red explosion phenomenon detracts from the stealth of the whole monitoring system and the LED brightness will also decrease after the long-term use. This paper proposes a solution based on an ARM control module platform, a laser light source, and an HD MCCD camera to improve the quality of video surveillance system in the full-dark environment. The new platform occupies a small volume, and the infrared laser light module compared with an LED of the same brightness has low power consumption, no red explosion phenomenon, and reduced heat associated with it. The ARM platform simplifies the video capture and has better image processing capability, which enhances the video quality. This improved the overall versatility of the monitoring system. The video data is stored in a removable SD card format and may be uploaded to the server by means of a wireless network .
