Milesight How to Use Lightning Protection User Guide
Recommendations for Lightning Protection
Outdoor Protection
Installation Suggestions
- Installed on the pole, the camera should not be at the very top. Slightly move it down, or it is easy for the camera attract lightning.
- It is better to have a lightning rod at the top of the pole.
- the camera housing should be grounded.
- In theory, it would be better to add a Junction Box, so the tail wire can better avoid lightning with a shell protection.
- If possible, deploying lightning arrester on site, especially in coastal areas where there are often thunderstorms
Note:
- When you use PoE, the network port of the 2-in-1 lightning arrester does not work.
- Please check purchase advice of Lightning Arresters or consult Milesight support.
Indoor Protection
Installation Suggestions
- For systems with unstable voltages, transient severe surges may cause damage to switches and cameras. Therefore, voltage regulators need to be deployed in the system.
- Pay more attention to surge intrusion through signal wires. It is better to add a signal surge arrester.
Troubleshooting Steps for Lightning Strikes
Installation and Weather
Step 1: Confirm the installation environment; (Whether the camera is
installed in an open outdoor or on a pole? Whether lightning arrester is
installed? Whether the camera housing is grounded);
Step 2: Confirm if a thunderstorm occurred recently;
Step 3: Share the information with Milesight Support
Power Supply Method
If the camera model supports both DC and PoE, try both of them to confirm which circuit is damaged.
Step 1: If the camera can not power on with DC but can power on with PoE,
there is a high possibility that the motherboard is damaged;
Step 2: If the camera can not power on with PoE, but can power on with
DC, and there is an IR-CUT sound with IR LED on, but the camera cannot be
accessed when the camera starts up, the possibility is that the interface
board is damaged;
Step3: Contact Milesight Technical Support for RMA.
Disassembly and Inspection
Step1: Disassemble the camera to check if there are obvious burn marks on
them other board and interface board;
Step2: If there are no obvious burn marks on the board, use a multimeter
to measure whether the components on the board are short-circuited;
Step3: Share test results with Milesight Support.
