Why do security cameras attract lightning?

Security and traffic control cameras are widely used in today's urban life. They are installed on poles or towers with 10 to 50 meters heights which are mostly made of metal and carry a very high risk of being struck by lightning.

A number of different camera models are used together at a single point in order to track the traffic and/or support public security. Data collected from the cameras is sent to a control unit to be monitored by operators. In most cases, transmission units are located just by the cameras or installed on the pole.

During a storm, when there is no lightning protection on these poles, ground charges climb up on the pole since that they are attracted by the opposite charges of the storm cloud. As the storm reaches to a certain level of development, all ground charges at the top of the pole are emitted towards the opposite charged downward streamers of the cloud.

The meet of the upward charges with the downward streamers form a lightning channel. Lightning current flows through this channel, hits the pole and reaches to ground. During this flow, lightning current damages the cameras on the pole, damages the transmitter and breaks down the link between transmission unit and control room. As a result; all data during and after this incident are lost untill the maintanence date and also cameras and transmission units must be renewed.

There is definitely a need of lightning protection for cameras.

Lightning Rods on Camera Poles?

​​Security and traffic control camera poles are made of conductive material and they are the highest structures around. This makes the poles open to lightning threat and they need to be protected against lightning strikes and possible damages.

In case of use of a lightning arrester solution, the arrester collects all ground charges on itself and emit them towards the cloud charges in order to “protect” the surrounding area which is exactly their purpose of use.

However, lightning current must reach the ground through the shortest and fastest way which is still the camera pole body. Eventhough a conductor cable is installed between lightning arrester and grounding system, lightning current prefers to follow larger surfaces instead of a conductor cable and flows through surface of the pole.

In this case, using a lightning arrester does not solve the problem and all devices on camera pole are still affected by lightning current and all data is still under risk of getting lost.

Lightning protection for security cameras

As a result, there is no difference between protecting camera poles with a traditional lightning arrester and leaving the pole unprotected against lightning strikes.

EvoDis® Lightning Prevention System

Lightning protection for security cameras

​​The best way of being protected from direct lightning strike damages and prevent secondary damages by electro magnetic field of lightning current is keeping lightning away from protected structure.

EvoDis® Lightning Prevention System dissipates ground charges on the camera pole, keeps the surrounding electrical field strength lower than the threshold level and minimizes the risk of getting hit by lightning.

EvoDis® Lightning Prevention System dissipates ground charges on camera pole through thousands of tiny sharp points and blocks the emission of these charges. This process makes the pole “invisible” to lightning and prevents a possible strike on it.
