Wired or Wireless CCTV?

When it comes to choosing a CCTV system for your home or office, there are a number of options. Wired CCTV systems are connected via wires, while wireless CCTV systems relay information through a wireless transmitter.
Both wired and wireless CCTV cameras have various benefits and drawbacks that you will want to consider before deciding which is best for your security system.

Wired CCTV

Until recently all CCTV systems were wired. Only since the advent of Wi-Fi internet connections has wireless CCTV become an option. Wired CCTV is generally more reliable than wireless, and so more popular with offices, businesses and homes that need advanced security.

How wired CCTV works

Wired CCTV works by connecting each CCTV camera with the monitor or recording device via a cable. Coaxial cables are commonly used, which are similar to normal home TV cables, but there are other CCTV cables you can use. Wired CCTV cameras compress the images as they are captured, transferring them as data packages through the cables to the monitor or recording device.

  • Benefits of wired CCTV

    • Wired CCTV systems tend to be more reliable, as there is no risk of interference from other signals or devices. There is less likelihood of losing signal or filming being interrupted.

    • Power and video can both run through one cable, so everything can be centrally located and managed.

    • There is a wider selection of cameras available to connect through wired cables, and they often perform more functions than their wireless counterparts, such as zoom, rotation, and audio.

    • There is no need to place cameras close to a power source, as cables will transmit power over long distances easily.

    • Wired CCTV systems are much less likely to be hacked than wireless CCTV systems.

    • Smart Home wired CCTV systems enable you to view camera footage remotely, so you always know what’s happening around your home.

  • Drawbacks of wired CCTV

    • Most wired CCTV systems are complex to install, so you will likely need to hire and pay a professional to set it up for you. Installation can be pricey and a little invasive – holes may need to be drilled through walls to feed wires through.

    • Wired cameras are usually considerably larger than wireless cameras, and they may detract from the overall aesthetic of your home.

Wireless CCTV

Although a relatively new option for CCTV systems, wireless CCTV has come on in leaps and bounds in recent years. While it still doesn’t quite match up to wired CCTV in terms of reliability, it makes for an effective additional security measure in homes.

How wireless CCTV works

Wireless CCTV, also known as Wi Fi CCTV, transmits images into data, which is then sent through a network or internet connection to a recording device or monitor. Some wireless CCTV cameras still require a wired power source, so these aren’t truly wire free, while others are battery powered, making them completely wireless.

  • Benefits of wireless CCTV

    • Wireless CCTV cameras are usually smaller than wired CCTV cameras.

    • Wi Fi CCTV cameras are easier to install, and it is possible to set your wireless CCTV cameras up yourself.

    • Wireless cameras are also easy to adjust and move to suit your needs.

    • It’s easy to add additional wireless CCTV cameras to your system as you need them.

    • It’s easier to conceal and hide wireless CCTV cameras as they are smaller and have less connection wires.

    • Low to mid-range wireless CCTV cameras are more affordable than wired cameras.

    • Smart Home wireless CCTV systems enable you to view camera footage remotely, so you always know what’s happening around your home.

  • Drawbacks of wireless CCTV

    • A lot of wireless CCTV cameras still require a wired power source, so they aren’t truly wire free.

    • Those that are wire free require battery power which will need to be replaced or recharged regularly to ensure full CCTV coverage.

    • If you have set the system up yourself there is always a risk that it might not be in the optimal position to capture the best footage.

    • Wireless CCTV cameras are more likely to lose connectivity due to interference from other devices or adverse weather conditions.

    • Connectivity is also unreliable when the cameras are situated further away from the connecting wireless device. The cameras can only be placed a certain distance away from the receiver or they will not transmit.

    • A wireless receiver is required to gather the feed signals and pass these on to the recording device. An additional step in the connection means there is an increased likelihood that the connection could be lost.

    • Wireless cameras are at risk of being hacked or compromised remotely.
