The traditional mechanical water meter requires manual on-site meter reading, which is not only inefficient, but also increasingly expensive. At the same time, manual meter reading affects the normal life of residents. Through the camera direct reading meter head, it can be upgraded to a remote meter reading water meter without dismantling the original mechanical meter. Remote meter reading is realized through wired transmission or wireless GPRS transmission. Camera remote meter reading is also known as "video remote meter reading" and "visual remote meter reading". Camera remote water meter is a common water meter surface plate with camera and electronic module remote water meter. The meter reading mode is to capture the digital image and then transmit it to the computer for image analysis to obtain the current water consumption data, so there is no possibility of misreading the data.
