The Impact Of Lightning On Electronic Security Equipment
South Africa has one of the highest lightning strike densities in the world. Coupled with the fact that the country has long overhead power lines that run the full length and width of the land, it creates a problem in that the power lines are vulnerable during electric storms.
Security equipment manufacturers normally have multiple layers of protection added to the equipment they make. A powerful strike to the system will however render the protection useless.
Lightning static can also cause severe damage to electronic equipment.
It is advisable to remove the transformer plug from the power source where possible if there are signs of heavy lightning.
Remember to plug all plugs in and turn on the power immediately after the storm is over. It is important to make sure that your security system is correctly earthed. Adding surge protection will also be an advantage.
