1. Recommendations for Lightning Protection
(1) 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.

Figure3 3-in-1, 2-in-1 and PoE Lightning Arresters
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.
(2) 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.
2. Troubleshooting Steps for Lightning Strikes
(1) Installation and Weather
Step1: 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);
Step2: Confirm if a thunderstorm occurred recently;
Step3: Share the information with Milesight Support.
(2) Power Supply Method
If the camera model supports both DC and PoE, try both of them to confirm which circuit
is damaged.
Step1: 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;
Step2: If the camera can not power on with PoE, but can power on with DC, and there is
3
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.
(3) Disassembly and Inspection
Step1: Disassemble the camera to check if there are obvious burn marks on the
motherboard 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.
