There
are many cases involve CCTV Camera and lightning danger. To protect the CCTV
Camera, the customers should now the surge
protector.
What
is surge protector? Surge
protector is an appliance designed to protect electrical devices from
voltage spikes. A surge protector attempts
to limit the voltage supplied to an electric device by either blocking or by
shorting to ground any unwanted voltages above a safe threshold.
The
terms of Surge Protection Device (SPD) is
used to describe the electrical devices typically installed in power
distribution panels, process control system, communication systems, and other
heavy-duty industrial system, for the purpose of protecting against electrical
surges and spikes, including those caused by lightning. Scaled-down version of
these devices is sometimes installed in residential service entrance electrical
panels, to protect equipment in a household from similar hazard.
Many
power strips have basic surge protection built
in, this are typically clearly labeled as such. However, power strips that do
not provide surge protection are sometimes
erroneously referred to as “surge
protectors” by persons who do not understand
their purpose and function (Wikipedia).

of Lightning Dangers
Here are some tips to protect your
CCTV system from lightning dangers:
If you think you know how to make your CCTV
system safe from lightning, please think again!
How to be safe from lightning?
- Believe that there are many Point-of-Dangers (PoDs) and this PoDs can affect the CCTV system in a bad way;
- Learn where the CCTV system are located and do something beforehand, because while indoors, you will not be aware of impending dangers from lightning;
- If you are aware of impending dangers from lightning, do not go near any PoD! There is no safe-time to unplug anything.
Do something right beforehand:
- Isolate each CCTV system from induced lightning surges, with lightning isolators (surge protector device)!
- Do not go near any CCTV system while bare-footed! Wear rubber sandals or stand on dry and insulated floor-mat or Equal Potential Safety Mat (EPSM), if you have one installed;
- Use remote-control, if possible;
- Be warned: INSURANCE is not a safety-measure! It is a cut-loss measure, often associated with dangers that could not be technologically avoided. Lightning dangers are avoidable, now!
How to create Safe-Island for your CCTV system?
- Identify all CCTV equipment in a setup and all must draw power from one and the same power surge protector only;
- Identify all the connections from this island to outside the CCTV system or to another island (including earth or ground wire, if any);
- Choose one or more lightning isolator (surge protector) suitable for the purpose, and install correctly;
- Interconnections within this island can be directly interconnected, as safe-cables! Safe-cables must not be too near to un-safe cables (from outside this island)!
- Any direct connection to outside, not via surge protector, renders this island to become un-safe!
CCTVMALAYSIA2u.com provide full
range of Video surge protectors help prevent damage to sensitive electronic
equipment due to differences in ground potential, power surges and area
lightning strikes. It is easily installed between the coax video cable and
equipment connection jack, our surge protectors intercept repeated surges and
ground along a conductive wire without any loss of signal quality. These products
