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, you can read this blog written by Olivia, an experienced tech editor of ZOSI.

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.

You can get more details about wired security cameras in this post (written by Jenny, ZOSI’s top editor, who has 10-year experience in wired security camera field).

You’ve got the 2 main types of wired security cameras. Let’s view the positives and negatives of wired CCTV security IP cameras.

Wired security camera pros:

  • No interference from nearby devices
  • More stable data transmission
  • Ideal for several zones of protection, good for large homes

Hard-wired CCTV security camera cons:

  • More challenging to install
  • Drilling holes needed to run wires throughout your home
  • Less portable

Part 2. Introduction to Wireless (WiFi) Security Cameras

Wireless security cameras are typically divided into 2 types: battery or solar-powered wire-free security cameras and plugged-in wireless security cameras.

The video transmission of both security camera types is totally wireless. The biggest difference between them is the way in getting the power supply.

Battery or solar-powered wireless security cameras are powered by batteries or solar panels, which makes them zero wire. This type of security camera is the most portable and easy-to-install home smart security cameras.

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.

Just like wired surveillance security cameras, wireless residential and business security cameras have their strengths and drawbacks.

Wireless security camera advantages:

  • Easy and quick to install.
  • More flexible
  • More portable

WiFi security camera disadvantages:

  • Possible WiFi interference from nearby devices
  • Risks of being hacked
  • More expensive

Now you are equipped with basic knowledge of the pros and cons of both wired and wireless security cameras, please read on to view the comparison of the 2 kinds of surveillance security cameras.

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:

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 ZOSI ZNC281 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 signals to work, it is inevitable that sometimes the WiFi signal is weak or influenced by the environment, such as thick walls and weather (click here to learn how to solve the problem).

If you prefer a more stable data transmission, you can buy wired PoE IP security cameras. This type of security camera only needs 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 evidence to catch the bad guy.

And here is the best example:

A meter reader triggered the C281 camera when she approaches the homeowner’s shed. The battery-powered camera sounds the customized alert instantly but the meter reader feels quite confused since she has no ideas where the sound comes from.

You can buy a battery-powered wireless security camera with local memory card storage, so you don’t need to pay monthly fees for the cloud storage.

Some high-quality battery-powered WiFi security cameras, such as ZOSI C281, support up to 16GB SD card storage, which enables you to store several hundreds of motion videos. So, you won’t miss any important moments.
