In this Article, I will explain to you how to setup VC0706 camera module just bought online, including communication between the camera module and Arduino UNO, how to take a picture of the camera module and so on. This is an Arduino camera module, designed for image acquisition and processing applications designed for surveillance cameras digital image processing chip-VC0706, based on the TTL communication interface, Arduino controller is very easy to connect, you can read the image through the UART serial port and Data port, and then perform some image processing. This is a detailed DIY guide for VC0706 TTL and UART cameras.
DIY Camera using VC0706 Camera module with Arduino UNO
Step 1:- Sensor Detail
This camera module can perform image processing on video signals from CMOS sensors such as AWB (Auto White Balance), AE (Auto Exposure), and AGC (Automatic Gain Control). In addition, the module will output high-quality digital video signals through the standard CCIR656 interface under the combination of advanced technologies such as image enhancement processing under low illumination, intelligent prediction and suppression of image noise, and the like.
The VC0706’s built-in JPEG decoder enables re-encoding of captured images, allowing external controllers to easily read M-JPEG video streams for dual stream camera design. VC0706 support screen character and pattern superimposed motion detection and OSD display, customizable detection area and sensitivity.
