Part 1. Understand Wired CCTV Security Cameras
Wired security cameras, such as PoE IP cameras 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 just use an Ethernet cable to connect to your router or NVR for both data and power transmission.
If you wanna dig further into Cat 5 or 6 security cameras,
Traditional hard-wired analog security cameras need 2 cables, one for power and one coaxial cable connecting to the DVR for data transmission.
While wired PoE security cameras can work standalone, analog surveillance cameras need to connect with the DVR. The images of PoE security cameras are much clearer than that of analog type.

Part 3. Wired or Wireless CCTV Security Cameras: Which One to Choose
You can buy suitable wired or wireless security cameras based on your specific needs. We compared the 2 types of security cameras on the below 4 aspects:
- Network Signal
- No Power & Internet
1. Buy Wireless Security Cameras for Easy Installation and Flexibility
Wireless surveillance alarm security cameras take less time to install and require less drilling or wiring work compared with traditional hardwired security cameras.
When it comes to wiring work, battery-powered wire free security cameras should top your list.
You don’t need to do any drilling or wiring job at all. Just place the camera to the position you want, and you are good to go.
Let’s take wireless battery powered security camera as an example.
You can simply install the camera with 3 simple steps: Launch the App on your phone -> Scan the QR code of the camera -> Start live streaming.
In terms of wired security cameras, because of trailing cables, wired security cameras cannot be easily moved or re-positioned after they have been installed. In this aspect, wireless security cameras are better than traditional hard-wired security cameras.
For your reference: With the progressive technology, many security camera companies adopt PoE (Power over Ethernet) to power wired security cameras. Thus the installation process becomes easier than those traditional wired security cameras (such as analog cameras). If you prefer wired security cameras, remember to get DIY PoE IP security cameras.
2. Purchase Wired (PoE) Security Cameras for More Stable Network Signal
Since wired security cameras are directly connected to your home network router, you don’t need to worry about the Internet loss or interference. While wireless security cameras depend on WiFi signal to work, it is inevitable that sometimes the WiFi signal is weak or influenced by the environment, such as thick wall and weather
If you prefer a more stable data transmission, you can buy wired PoE IP security cameras. This type of security cameras only need a Cat 5/6 cable to realize both power and data transmission, so it’s also very easy to install and set up.
3. Pick 100% Wire Free WiFi CCTV Security Cameras for Perfect Aesthetics
Basically, one of the biggest differences between 5MP,4MP (1440p) and 2MP (1080p) wired and wireless security cameras is in decoration-friendliness and aesthetics. Most wired surveillance systems require you to drill holes and run security camera wires indoors and outdoors, which is not appealing visually.
With wire-free battery operated security cameras, you can remove them at any time without leaving any damage to your property.
A wireless security camera installed inside your home would not stick out too much, so your guests or friends would not feel invasive when visiting your home. If you want to disguise your wireless security cameras, you can use the skin suits to make them more hidden.
You can just place the 100% wire-free security cameras anywhere you like without drilling holes or running wires. Just place and go, and all is done.
4. Wire-Free vs. Wired Security IP Cameras for Areas Without Power & Internet
When you need to protect your remote properties, such as farm, barn and garage, where power supply and Internet access are not available, wire-free video surveillance security cameras are your only option.
Battery powered wireless security cameras enable you to get motion videos when there are motion events. You can play back the recorded videos to see who and what triggered the alarms. If there is a thief, you can keep the videotapes as the evidence to catch the bad guy.
