Basics of Wired and Wireless Security Cameras

There are different types of wired and wireless security cameras, each with its characteristics.

What is a wired security camera?

Wired security cameras, such as PoE IP and hard-wired analog cameras, need wires to realize video transmission and power supply.

  • Wired PoE IP security cameras typically use Cat 5 or Cat 6 Ethernet wires to communicate with your home network router or NVR. In other words, you can use an Ethernet cable to connect to your router or NVR for data and power transmission.
  • Traditional hard-wired analog security cameras need two cables, one for power and one coaxial cable connecting to the DVR for data transmission.

What is a wireless security camera?

Wireless security cameras do not require a physical cable connection to transmit data or video footage. Instead, they rely on wireless technology, typically WiFi or other wireless protocols, to send video and audio signals to a receiver or recording device.

Wireless security cameras are usually divided into battery or solar-powered wire-free security cameras and plugged-in wireless security cameras. The video transmission of both security camera types is wireless. The most significant difference between them is the way of getting the power supply.

  • Battery or solar-powered wireless security cameras cameras are powered by batteries and usually have solar panels as a power backup, which makes them zero wire. This type of security camera is the most portable and easy-to-install home smart security camera.
  • Plugged-in wireless security cameras need to be plugged in to get power. The communication between the camera and your home router is also through the wireless signal.
