Wired vs Wireless In The Surveillance World

Wired vs Wireless In The Surveillance World

With wireless technologies there are a few standout advantages over wire. First of all it eliminates the need to run a long length of cable to get the video signal from your camera to your recording device (DVR, VCR, etc..). This is extremely beneficial when installing the system in a home or small business where it could be quite tricky to try and run cables for power and video. Another benefit is the obvious mobility a wireless solution can offer. Being able to quickly remove the camera and receiver and relocate them to a new spot when needed is quite handy at times, and makes for a much less complicated situation to the average user.

Wireless technology also comes with it share of disadvantages as well. The main problem faced by many people when using a wireless surveillance system is that of interference. Interference is a huge problem in the wireless world; it can come from cordless phones, cell phones, thick surfaces to go through, close power lines, weather, or even in extreme cases by sunspots. Now some wireless technology has been adapted to help prevent these forms of interference (such as using a 900MHz system where 2.4GHz would be interfered with by a cordless phone); however even with this somewhat interference free technology they are still limited to the number of devices that can be run on the same frequency, which makes large scale application almost impossible.

Another distinct disadvantage of wireless surveillance is that even though you won't have to run a video cable to your camera, you will still need to have some form of power source at the unit. This power may come in the form of having to plug into an outlet nearby, running an extension cord to it, or using an adapter to connect a battery. The problem however is that this need for power at the source partially makes the reason for having wireless moot. By having this power source you are potentially making the camera more obvious to those near it or your ability to conceal it is greatly reduced. Furthermore by using a battery you are greatly limiting the amount of time your camera can run for without having to consistently change the battery out when it gets low.

Now as for wired surveillance camera solutions we run into some great advantages as well as disadvantages. A main advantage of wired over wireless is that the worry of interference doesn't present itself for the most part, and you don't have to worry about if your phones or other wireless technologies will interfere with your video signal. This proves quite necessary especially in very large scale surveillance operations where large amounts of cameras may be running (such as a casino). Another advantage also created in having a wired camera solution is the eliminated need of having to have a receiver present to grab all your video signals and then pump them into your DVR. Instead with a wired solution you can run your video signals directly to your recording source without needing an intermediary in between. Finally the ability to place a wired camera most anywhere as long as you can get cable to it gives it the biggest advantage of all, where as a wireless solution needs to be near a power source.

The key disadvantages to wired solutions are two fold. First of all with a wired solution your obviously have to get your cables ran in your home or business to the camera and this can be a tricky process especially if you want the cable concealed and professional looking. In these cases an average user would generally have to hire someone to install the device and cabling for them which adds in some extra costs. Secondly for wired surveillance there is the disadvantage of mobility. Wired cameras and devices do not have the mobility that wireless camera users will enjoy and it will be a much more permanent solution when installed.

Ultimately in all of this a consumer needs to consider a few factors when deciding if they want to go with a wireless or wired surveillance solution. If the person wants a simple easy setup with only a couple cameras for his home or business then they will probably prefer a wireless configuration (obviously also keeping in mind the interference possibilities). However if someone is looking to install security cameras on a large scale with hundreds of video feeds, then it would definitely be better for that person to go with a wired surveillance solution In the end this choice is still based upon a persons situation and needs for surveillance.
