My outdoor dome camera (wired version with no WiFi) has on the back an earthing connection. Hikvision's manuals do not handle this topic at all, i.e. if earthing is mandatory, recommended, etc.
Electromagnetical considerations argue for effectively earthing the camera. Electrical hazards argue as well for effective earthing, especially if the connecting ethernet cable is long, i.e. the ethernet switch is far away from camera. In case of lightning, voltage differential at the two ends of the cable may burn electronics connected at the two ends.
Any experience in this field ?
Good to hear from you, folk!
