Since there is so much variety in the features of security cameras today, each type of security camera comes with its distinct uses. So, one good way to approach the decision is by deciding between the type of connectivity the security camera offers. In other words, deciding between the wired vs wireless security camera. Both have their pros and cons. And by knowing about them you can easily decide which one suits your needs better.
Wired vs Wireless Security Camera – The Difference
Here’s a look at the difference between wired and wireless cameras and their pros and cons, so that you can decide.
Wired security camera
A wired security camera is physically connected to a video recorder via cables. These cameras use two types of video recording systems: The Digital Video Recorder (DVR) or a Network Video Recorder (NVR). The DVR works with CCTV cameras (analog) and uses coaxial cables for connectivity. They either store footage on an SD card or come with a central hub to store the footage. Whereas, the NVR works with IP cameras (digital) and uses ethernet cables (PoE) for connectivity. Wired security cameras either store footage on an internal SD card or store it on the central hub. Moreover, they are also capable of sending the footage to the internet for cloud storage. In addition to that, the wired security camera is mostly powered through an AC outlet however some may also make use of a battery for a backup.
Wired Pros
- Better image and audio quality – since the camera is connected to the monitor or DVR directly, there is no loss in image or audio quality.
- More reliable – wired cameras are less likely to experience interference than wireless ones.
- Less vulnerable to hackers – since these cameras operate over wires within the premises of the home or office, they are less prone to hackers and other external threats.
Less vulnerable to theft – Wired cameras are fixed permanently, and are usually difficult to detach or move which makes them less prone to theft.
Wired Cons
- Limited range – since the camera is wired to the monitor or DVR, it can only be used in the area where the cables are installed.
- Prone to damage and vandalism – thieves could easily cut the cables and steal the data if the cables and recorder are not well-hidden.
- More expensive – wired cameras typically cost more than wireless options since they require long cablings to cover larger areas.
- Difficult to install – Installing a wired security camera can be difficult, especially if you are not familiar with cabling and electronics.

- Limited cameras on wired security camera systems – Since DVR comes with limited slots for cameras, it is usually difficult to add more cameras to home security systems.
Wireless Security Camera
A wireless security camera sends audio and video signals to a video recorder via WiFi or a cellular network. The signal is transmitted through the air and does not require any cables. These are IP cameras and use two recording systems: the traditional NVR (Network Video Recorder) or Cloud NVR (Cloud Network Video Recorder). The wireless cameras with traditional NVR record footage either on their internal SD card or record it on the central hub. Whereas, wireless cameras with Cloud NVR record footage on cloud storage over the internet. Moreover, most wireless security cameras are battery-powered. However, they are not necessarily wire-free since some are powered via a basic home electric power outlet. Others may be more hybrid and function while being charged.
Wireless Pros
- Ease of installation and setup – most wireless security cameras come with a simple plug-and-play installation process. You don’t need any special skills or tools to set them up.

- Limited range – like wired cameras, wireless cameras have a limited range and can only be used in areas where the Wi-Fi signal is strong.
- Vulnerable to hackers – since these cameras operate over a wireless network, they are more prone to hackers and other external threats.
- Prone to theft and damage – thieves could easily damage the wires or steal a wireless security camera if it is not well-protected.
Wired vs wireless security camera: Advantages and disadvantages
As we know security cameras come with many advantages and disadvantages. However, there are some advantages and disadvantages of security cameras that are specific to wired and wireless models. Let us clarify them for you.
What are the advantages of wired security cameras?
The main advantage of wired security cameras is that they are much more secure than wireless cameras. This is because wired cameras cannot be as easily hacked or intercepted as wireless cameras can be. The footage stays private within your home network and your privacy is less likely to be breached by outsiders. Moreover, since these systems operate through wires within the vicinity of your home or office, they are also less affected by weather conditions and radio waves. They are less likely to experience signal interference than wireless cameras, ensuring a more reliable connection.
Wired cameras are usually more visible than wireless cameras and usually a better deterrent to vandalism and theft. Similarly, since they are fixed with wires and cables they are hard to take off and steal, unlike wire-free cameras which can be easily stolen. Finally, they are also typically much higher quality than wireless cameras, providing clearer images and videos, which is very helpful in identifying intruders and thieves. These cameras are usually considered a better option for outdoor security cameras.
What are the disadvantages of wired security cameras?
The main disadvantage of wired security cameras is that they require a more complex installation process. This is because wires need to be run from the camera to the recording device or power source. This wired system usually costs you more money for running long cables across several cameras located in distant locations. Drilling the walls and keeping the wires hidden and tidy requires another effort and expense. One of its drawbacks is that wired cameras are also more difficult to move to a new location and reposition than wireless cameras. It’s another downside, is that a renter may not allow you to use them on his property, so it’s not ideal for those who live in rented houses and apartments. And finally, if the wire is cut or damaged, or if there is a power outage the camera will no longer work.
What are the advantages of wireless security cameras?
The main advantage of wireless security cameras is that they are much easier to install than wired cameras. This is because there are no wires to run from the camera to the recording device. All you need is a Wi-Fi network or an internet connection. They mostly use rechargeable batteries for power supply that you can easily recharge or replace when needed. Moreover, they also use better power-efficient features like motion detection for low power consumption.
