To prevent hardware damage in regions that experience frequent thunderstorms, SharpV cameras must be properly earth grounded.
Before you install a SharpV camera outdoors, investigate the lightning frequency for the region.
SharpV grounding guidelines
Depending on the installation, there might be many ways that the camera can be properly grounded. If you respect the following general guidelines, you can be sure that the camera is safely grounded.
- You must install an earth-grounded surge protector between the Ethernet switch and the camera. The surge protector that is protecting the camera should be as close as possible to the camera.
- Ground all devices that are in the proximity of the camera to a single point. This ensures that the system is not damaged due to a difference in voltage between devices.
- The ground bonding point should be as close as possible to both the camera and the surge protector.
Earth ground or safety ground
If power is supplied to the enclosure using a three-wire cable (positive, neutral, and ground), you cannot use the cable's ground wire to ground the camera. This is a safety ground and cannot protect the hardware from a lightning surge. To ground the camera, you must use a proper earth ground at the base of the mounting pole (as close as possible to the camera), or create a floating circuit.
Grounded circuit or floating circuit
It is recommended that you install the camera with an earth ground. However, if you install the SharpV camera on a non-conductive surface, (for example, a wooden pole), you can leave the camera and mount as a floating circuit, and earth grounding is not required.
