10.2 Camera
Introduction
1) Firstly, user needs to activate camera according to the manufacturer’s handbook. The ONVIF protocol should be activated, otherwise, it could not be used in WECON HMI;
2) Set camera username and password, it is recommended when user sets same username and password for more than one camera;
3) It is essential to make sure camera and HMI are in same LAN IP section;
When HMI and camera are connected directly, please use static IP for both HMI and IP camera. For example, HMI IP is 192.168.1.1, gateway is 192.168.1.1. Camera IP is 192.168.1.2, gateway is 192.168.1.1;

4) Username and password should be confirmed before using Do not try the incorrect username and password to search or connect the camera. After more than a certain number of tries, the camera will be locked. During this period, the camera will reject any connection. Generally, it takes half an hour to unlock. User needs to wait;
5) It is not suggested to connect the same camera with PI8000 and PI9000 series HMIs at the same time, otherwise IP camera will show blurred screen;
6) When the camera is disconnected due to network, it will try to reconnect for each 20 seconds interval. (frequent retry action may be considered as virus behavior);
