16 16  AIS is a video photo recognition sensor, the sensor can be used in electricity meters, gas meters, water meters, pressure gauges and other types of meters. Accurately identify the number of the current dial or upload the picture of the current dial for comparison, which can replace people to go to the door to read the meter, and is more accurate and energy-saving than the meter. The first thing to do is to fix the AIS sensor, the end direction needs to be aligned with the object that needs to be identified, you can check whether the object all appears in the lens range through the upper computer, and then calibrate, Chapter 2 will explain the calibration method of different tables.

22 -The factory default firmware of AIS Sensor is a digital wheel dial. It is recommended that the distance between the camera and the digital wheel dial be 3cm-7cm when installing AIS01-LB. Because the distance is too far, the camera's flash will not be able to illuminate the digital wheel dial to obtain readings.

353 353  
317 +Each AIS Sensor is shipped with a sticker with the default DEV EUI as below:
354 354  
355 -You can utilize a couple of pea clips or other suitable fixtures to securely fasten the AIS sensor and ensure precise alignment of the camera with the pressure pointer meter.
