Comparing wired and wireless video surveillance systems: which is right for you?

Your home is probably your most valuable and sentimental possession, so we understand your wish to do everything possible to protect it. The same applies if you own an office building or another type of property. Installing security cameras to capture any suspicious behaviour, vandalism or, even worse, theft is a top priority when it comes to protecting property.

As in any other niche, choosing security equipment turns out to be somewhat complicated. With so many brands, all promising that their technology will protect you, it is hard to choose a solution.

One question turns out to be fundamental when it is time to choose a video surveillance system: a wired or a wireless security system?

To make an informed decision, it is extremely important to understand the difference between wired and wireless security systems, because it is not just about whether or not there is a cable.

Wired security systems: high efficiency in the long term

Wired security systems, as you might expect, require cables for power, internet connection and video transmission. This solution is usually used in larger properties, but in general wired security systems are the most recommended, whether for a large or small residential property, an office building or another type of property.

How do wired security cameras work?

Every element of a wired security system (camera, recorder and router) is connected with cables in one of two ways:

Two cables: one carrying the voltage that powers the camera and another providing the video transmission. These cables are usually Siamese cables, so they are 2 cables in one sheath.

A single cable carrying both power and video transmission - often called Power over Ethernet or POE for short.

Advantages of wired security systems

Network reliability

Since wired security systems receive power and connectivity directly from physical connections, they are not susceptible to wireless signal interference. No Wi-Fi jammer will block the connection and leave you vulnerable to a system outage. Of course, a thief could simply cut a wire, but if your installer hides the cables to keep things as secure as possible, this cannot happen.

Scale and property size

Wired security systems, such as DSC and Milesight, can support larger properties that may need multiple cameras for complete coverage rather than just a few access points. Although the size of a property, whether residential or commercial, is often the deciding factor for many, wired systems are among the most preferred because they deliver maximum efficiency.

A permanent solution

A wired security camera system is great for homeowners or businesses with a permanent location. It offers long-lasting security and becomes an integral part of the building.

Disadvantages of wired security systems:

A wired security system requires professional installation and depends directly on the availability of electricity at the property.

Wireless video surveillance systems: easy, fast and convenient

Wireless security systems are the innovative alternative to wired systems. They can be good for smaller properties, but as technology advances and develops, they are also becoming suitable for larger properties, commercial premises and office spaces.

How do wireless security cameras work?

As their name suggests, wireless security systems do not require cabling for power, internet connection or video transmission. Only the devices providing the internet connection need a wired power supply.

Wireless security cameras work by transmitting recordings from a camera to a recorder, both of which are connected to your Wi-Fi network. This way you can have constant access to footage from the cameras via a built-in storage device or cloud storage.

Advantages of wireless security cameras

Simplified installation

Wireless cameras connect to a Wi-Fi network, so there is no need to run cables from the recorder to the cameras.

Flexibility

Wireless systems are easy to set up, take down and move. This makes them ideal for people who rent property, run businesses at temporary locations or often move house for various reasons.

Disadvantages of wireless security systems:

They are vulnerable in terms of Wi-Fi range; the cameras do not need a wired connection to the router, but unless they are battery-powered, they need power cables.
