Wired security is the most traditional and used primarily on larger properties. Wired security cameras, require cables for power, internet and video transmission.

How Do Wireless Security Cameras Work?

A cable runs either Coaxial or Cat-5 or Cat-6 from the camera to a recorder, which then connects to your router to be able for remote access via internet or smartphone. There are two choices for how a wired security system is powered, a separate power cord or one POE cable. POE or Power Over the Ethernet enabled systems only require one cable which provides both power and internet connection.

The Advantages of Wired CCTV

  • The main strength of wired security is reliability. Wired security systems are not susceptible to interference from wireless signals due to the physical connections between the camera, recorder and router.
  • Wired CCTV support larger system. Many home or business owners with large properties want comprehensive coverage versus only monitoring select access points. As such, they will often require more than four cameras in which case will need a wired system that can support and link all the cameras. Wired systems can support 4 to 32 cameras. In addition to connecting all the cameras, the security footage needs to be stored on a recorder, either a DVR or NVR recorder.
  • A wired security camera system is better suited for homeowners or businesses with a more permanent location due to the installation time. As wired systems require running cables, installation and mounting can be a longer process. Location of cameras and the recorder will depend on access to power outlets and you’ll need to run cables between devices. Once installed, wired systems are less flexible as moving cameras will require re-running cables.

The Disadvantage of Wired CCTV

  • One of the most significant drawbacks of a wired system is the installation process. Although installing a wired security system doesn’t require professionals, it does require running multiple cables which can be daunting for some. In addition, wired solutions tend to be less flexible when it comes to mounting than both wireless and wire-free solutions as they need access to a power outlet.
  • Another disadvantage of wired security systems is their vulnerability to power outages. If your property loses power, so will your security system. Although power outages are often infrequent, it’s an important consideration. For remote properties this can be mitigated with a backup generator.

Wireless Security Cameras

Wireless security systems are a great alternative to wired systems. Wireless systems aim to address the most significant downside to a wired security camera system: installation. The key difference between a wired and wireless security camera system is that security footage is transmitted wirelessly from the camera to the recorder.

How Do Wireless Security Cameras Work?

Wireless security cameras work by transmitting security footage from the camera to the recorder. You’ll have access to the footage either through a built-in device or cloud storage. Wireless systems connect to your Wi-Fi network (either wirelessly or with a cable), however, do still require wired power.

The Advantage of Wireless Security Cameras

  • Installation is one of the main benefits of wireless systems as compared to wired systems. As wireless cameras connect to the Wi-Fi network to transmit footage, there is no need to run cables from the recorder to cameras. As such, wireless cameras are more flexible in terms of mounting locations. The only limitation when it comes to mounting a wireless camera is access to a power source. Wireless solutions also include the option of running a cable from the camera to the recorder, which is can be useful if you have an area that lacks wireless coverage.
  • Unlike wired security camera systems which are more permanent, a wireless system is easy to setup, take down, and move. As such, wireless systems are ideal for renters or businesses in temporary locations.

The Disadvantage of Wireless Security Cameras

  • One of the significant downsides of wireless security cameras is they are susceptible to interference, which can make them less reliable in some situations. In today’s connected world, wireless signals and broadcasts are all around us, all the time. For wireless security cameras, these competing signals can pose a problem.|
  • Your wireless signal strength, or your scope of coverage, is tied to a number of factors including your router, the presence of, the amount of interference, and the route the signal has to take to get to your cameras.|
  • Wireless security systems are limited to only four cameras which for most homes is more than sufficient. However, if you have a medium to large property, we recommend you opt for a wired system.
  • As wireless systems still require a hard-wired power connection, they are susceptible to power outages as with wired systems.
