The calm after the storm – security measures to take note of:

Lightning is one of the most beautiful displays in nature. It is also one of the most deadly natural phenomena known to man. With bolt temperatures hotter than the surface of the sun and shock-waves beaming out in all directions, lightning is a lesson in physical science and humility.

Johannesburg has seen a number of electrical storms which have caused quite a lot of devastation in many areas. With flooding and lightning damage being one of its many casualties. These storms also play havoc on many security systems and leave your homes vulnerable to physical threats.

“We have had a number of call outs for repairs from lightning damage as well as attempted break-ins as a result of storms. Says Jason Mordecai MD 7Arrows Security. Many criminals are aware that when lightning strikes there is a high possibility that it can destroy your gate motor in seconds or wipe out your electric fencing in no time” he says.

Lightning does not have to strike your homes directly in order to affect the things inside of it. If there is something around your homes that is a conductor of electricity, this will act as a pathway for the lightning to enter your homes. Once lightning strikes the surge is powerful and moves through the channel of least resistance, which could be your circuit boards, electric fences, CCTV systems, gate motors, beams etc…

“We urge residents to be aware of this and evaluate possible weak security points as well as make sure security systems are in good working order before and after all storms” says Mordecai.

Tips for security measures before and after storms:

1. Always remain aware – being vigilant of your surroundings can determine whether you are targeted or not. The more aware you are of what is going on in and around your homes the better off you are.

2. After the storm have a look at any possible damage it caused. Take a walk around your homes, has your electric fence been damaged in any way? Is the fence undisturbed? Many people tend to disarm their fences during electrical storms due to false alarms. This would mean you wouldn’t know if its been struck or damaged. If possible do not ever disarm your fence, make sure that trees and bushes are trimmed in order to avoid false alarms.

3. After the storm check gate motors. If wires have been hit, it is often a possibility that the gate will continue to work and run on battery backup for a few days until it eventually dies.

4. After the storm give your alarm system a quick test. Your alarm system can also run off battery backup and therefore as with the gate motor you may not realise until the battery has fully died. Check that the power is on at the control pad of the alarm. It is also recommended that you test all sensors and beams and make sure everything is in working order.

“Should your home be affected by a lightning strike please act speedily and get everything repaired as soon as possible, criminals use your hesitation and delay in repairs to their advantage.” says Mordecai. You could also look into adding some lightning protection to your electric fences to possibly avoid it being set off and struck by lightning.”
