How Do Wireless Security Cameras Work?

Quick answer

How wireless security cameras work

Wireless security cameras send data over Wi-Fi instead of through physical cables. A wireless camera needs to be in range of a dependable internet signal to work correctly.

One small note: While some wireless cameras are battery powered and therefore truly wire-free, many still need to be plugged into an outlet because electric power is much more reliable than battery power.

Wireless security camera basics

Traditional wired security cameras require cables to send signals or transmit video feeds. Wireless security cameras are just a bit more modern—they use Wi-Fi to send and receive information, eliminating the need for jumbled wires and cables.

This means you can install a wireless camera almost anywhere inside or outside your home, without the help of an electrician.

Wireless camera pros and cons

Wireless cameras are convenient, but they aren’t the perfect solution in every situation. Consider the pros and cons of wireless cameras before you install one in your home.

Pros

  • Installation is simpler and probably won’t require an electrician
  • Cameras can be installed almost anywhere, as long as there is a signal
  • Mobile video feed access is usually an option
  • Moving cameras to a new home is easier
  • Remote control of pan, tilt, and zoom features is sometimes available

Cons

  • Wireless connection isn’t quite as reliable as a wired connection
  • Wi-Fi security cameras are usually pricier than wired cameras

Pro Tip

Check your signal strength before permanently mounting any cameras. A wireless security camera won’t be much use without a dependable Wi-Fi signal.
