How to Protect Your Security Cameras from Lightning

Why Are Security Cameras Lightning Magnets?

Contrary to popular belief, lightning doesn't strike at random. Rather, it follows the path of least resistance, which often involves elevated and isolated objects that can act as conductors. Security cameras are often mounted in such positions and connected to metal poles or structures, making them perfect candidates for lightning attraction. Having an understanding of these characteristics allows businesses to adopt strategic measures to mitigate the risks.

Safe Mounting and Installation

The first step in protecting your security cameras from lightning damage starts with thoughtful mounting and installation. Position your cameras in such a way that they are not the tallest objects in the area. Placing cameras lower on a structure and using non-conductive mounting materials like fiberglass or plastic instead of metal can reduce the likelihood of a strike. Also, consider installing lightning rods near the camera setup to divert lightning away from the equipment. Professional installation can ensure that your cameras are placed in the safest possible locations.

Proper Grounding

A well-grounded system can effectively divert the electrical current away from your equipment, sparing it from damage. To ensure the effectiveness of grounding, use a copper grounding rod driven at least 8 feet into the earth. Connect this rod to the camera setup using heavy-duty copper wire. The key here is to provide a more attractive route for lightning, guiding it safely into the ground and away from your valuable equipment.

Surge Protectors and Electrical Switches

While grounding can divert the electric current, surge protectors work to regulate the voltage that flows through your equipment. Surge protectors can be installed either at the electrical panel or directly at the point where the camera connects to the power supply. It's important to choose a quality surge protector that can handle the high voltages associated with lightning strikes. Make sure to regularly check and replace these devices as they can degrade over time. You can also use electrical switches to isolate the cameras during a storm manually, although this could leave you without surveillance for the duration.

Uninterruptible Power Supplies

Uninterruptible Power Supplies serve as your final line of defense in case of lightning. These devices can keep your cameras running during power surges or outages, ensuring continuous surveillance. While a UPS can't protect your cameras from a direct hit, it can certainly reduce the damage caused by voltage fluctuations. Choose a UPS that provides sufficient run-time to keep your systems operational until the power is restored, but don't rely on it as your sole protective measure.
