Surge Protectors
There are many power strips on the market today that do not provide surge protection, yet that is exactly what you might think you are getting. That’s why it is very important that you have knowledge on your side and that you opt to protect your electronics against voltage spikes caused by power outages or lightning strikes by using (at the very least) surge protectors.
Furthermore, when it comes to CCTV equipment you should look for more layers of protection than what a typical surge protector can provide. That’s where Uninterruptable Power Supply (UPS) units come in.
A continuous UPS is designed to convert AC power to DC power and store it on a battery. The UPS then converts the battery's DC power back to AC power and runs it to the AC outlets for your electronics. If the power goes out, your electronics should continue to run off the stored battery power for a limited amount of time. That time depends on the design and the number of cameras, DVRs, monitors, and/or computers you have running.
When choosing a surge protector or UPS unit you should know what each device has been designed to protect. For example, there are some devices which are designed for use with a plasma TV or personal computer and not for use with CCTV equipment.
When buying a UPS unit you should know how many surge protectors there are, how many watts of output it provides, and if the UPS unit is voltage compatible with the equipment you want to protect.
Remember, the primary role of surge protectors and UPS units are to protect the expensive equipment that you have already purchased. Don’t overlook such a step and be smart about your choices.
