How to buy the right CCTV system

CCTV systems are now commonplace in both commercial and domestic settings. They offer excellent security benefits and can even be used for keeping an eye on pets or family members.

How do CCTV systems work?

Fundamentally, all CCTV systems work by capturing live footage and then transmitting it to a recording device. The footage can either be viewed in real-time or watched later.

There are three main connection types available: BNC, Wi-Fi and Ethernet.

BNC connections work using a wired network. The captured footage is recorded in analogue format and sent to a digital video recorder (DVR).

WiFi connections are increasingly popular. The footage that is captured is sent over the internet in a compressed digital format to a device such as a smartphone, PC or Smart TV.

Ethernet-connected CCTV systems use an RJ45 ethernet cable to send their data and get their power. Like Wi-Fi systems, these record the footage in a compressed digital format and send it to the chosen device.

Key Considerations

  1. Footage Quality

    If you will need to get a clear view of a person’s face (or perhaps a car number plate) then you will need to opt for a high-resolution or HD/4K camera.

  1. Storage

    How many days of footage you need to keep and how many cameras you have recording at once will determine how much storage you need.

    3. Audio Recording

    If you need to capture sound as well as images, you will need cameras with built-in microphones.

    4. Constant or Triggered Recording?

    For efficiency reasons (including storage), you may want the recording to only happen when certain criteria are met, rather than constantly. If so, you can choose a system with motion sensors that trigger the recording.
