Wired vs. Wireless Surveillance

Posted 218 days ago ago by Jake Thomas

Thinking of going wireless for your surveillance needs? There are a number of things one should consider before ditching the cables completely.

Together, those three considerations can serve as a guiding light that can help you think about whether or not wireless is the way to go.

Pros of Wired

As with most things there are pros and cons to wired cameras, with the main pro being reliability. A wired surveillance camera is more reliable than its untethered counterpart in the sense that signal interference is less of a concern. Because wired surveillance cameras connect to a network or recorder via dedicated cabling, it is harder for other devices to interfere with the camera’s signal. This translates into better image quality and with backup power distribution, you can be sure a wired surveillance system won’t go offline in an outage.

Cons of Wired

The biggest con for a wired camera system is that it is more difficult to install than a wireless one. Installing a wired camera system often means pulling cable through walls, floors, and ceilings. That, however, is not necessarily a reason to write off a wired surveillance system as there are trained, experienced professionals out there that can help.

Pros of Wireless

And that brings us to the pros of wireless. A wireless camera is one in which video signal is transmitted through the air to a receiver that translates the signal into an image. This is where wireless has the edge because it removes the need to climb through drop ceilings and the like to install. Also, should you decide to relocate, a wireless system that transmits over a WiFi signal can be unplugged and taken with you.

Cons of Wireless

The term “wireless” can be something of a misnomer in the world of surveillance because despite the name, a wire will still be needed to power a wireless camera. And while they have the distinct advantage of easy installation, the placement of wireless surveillance cameras is largely dictated by the location of an electrical outlet. Wireless surveillance cameras transmit their signal in a frequency range that is flooded with use. Other devices operating at or near the same frequency as most wireless surveillance cameras can result in noise or interference, which can lower your image quality. Simply put, a wireless surveillance camera system just can’t match the resolution afforded by a wired one, at least not yet.
