Does CCTV Need A Power Supply & Work In The Dark?


Each business will require something different from their supplier when it comes to the types of security systems that they install. It’s important that organisations across the UK are ensuring that their premises are properly protected at all times — but how do they work most effectively?

Do CCTV cameras need a power supply?

There are two types of CCTV cameras that you can install, with this decision determining whether you need a power supply in order to monitor and record footage:

  • Wired — as wired cameras are fixed to an electrical source, you will need a continuous supply of power.
  • Wireless — wireless cameras rely on batteries, which will often need to be replaced, but do not require an electrical power source.

However, most IP CCTV systems today use Power over Ethernet (PoE), which can help businesses save on initial mains outlets and power cabling expenses, along with regular maintenance costs that will occur.

Do CCTV cameras work in the dark?

Depending on what you want your CCTV cameras to monitor, it’s important to consider all factors — including whether they are capable of capturing quality footage in the dark.

Of course, security cameras require some sort of light to capture high-quality surveillance through the day — and this is the same at night. Some cameras are designed with built-in infrared features which are invisible to the human eye but are able to produce enough light to capture viable recordings.

However, external lighting can also be used to record footage at night; from streetlamps to illumination from neighbouring buildings.

Not only that, some cameras can feature light-enhancing technology, such as the Axis Lightfinder and the Hikvision Darkfighter, which can improve visibility in areas that would usually be difficult to monitor.
