From tablets to control panels, wireless capability is cropping up in products in a variety of industries, and security is no exception. Wireless technology is readily available and inexpensive to incorporate into devices, which is why manufacturers are seizing the opportunity to produce and market a variety of Wi-Fi-enabled security products. But manufacturers aren’t the only ones who benefit from wireless; an increasing number of dealers and integrators are riding the wireless wave.

One reason for this shift in technological paradigm stems from installation procedures. Without having to run long stretches of cabling from the cameras, the installation becomes a much quicker job, requiring fewer hours of labor. Added mobility and flexibility are other appealing qualities of wireless cameras. In other words, a wireless camera can be easily installed, uninstalled, and reinstalled elsewhere on a premises, provided there is a viable power source and signal.

Although some wireless cameras utilize a mesh network, a Wi-Fi network is used most commonly to transmit data. Wi-Fi-enabled products adhere to at least one of three standards set by the Institute of Electrical and Electronics Engineers (IEEE): 802.11g, 802.11n and 802.11ac. The most commonly held standard today is 802.11g, which is able to transfer up to 54 megabits per second and has been implemented worldwide. Wi-Fi, in actuality, is an unlicensed radio frequency that transmits at a power level less than 1 milliwatt. This means it is open for anyone to use and is what has prompted its widespread usage.

A wireless camera has all of the equipment needed to transfer video already built into it. To transfer video, it is first compressed to a smaller size that facilitates transmission over the network — similar to how one might compress several photos into a .zip file to send in an email. Next, the camera encodes the video data into a series of 0s and 1s that is wirelessly transferred via radio waves (Wi-Fi) to a digital destination, such as an NVR or other data storage appliance.

Even though wireless video transmission is a growing trend in the security industry, some are hesitant to be swept up into the Wi-Fi current. As with any technology, wireless has its pros and cons. One real concern is the matter of the Wi-Fi signal: if there’s no signal, there’s no video. There is also the risk that a signal can be disrupted by changes in the environment surrounding either the camera transmitting the signal or the signal-receiving device. Metallic additions to a building, even a small change such as adding foil-backed wallpaper to a room, are known to disrupt a video transmission signal. In general, Wi-Fi coverage is more subject to change, and therefore, so is camera performance. The good news is that wireless camera systems are easily repositioned to address these kinds of problems. Still, regular testing is recommended to ensure that the signal is able to reach its destination at critical moments.

Although Wi-Fi might be what most often comes to mind when talking about wireless cameras, video transmission isn’t the only way in which a camera might be considered “wireless.” Battery-powered and solar-powered cameras with battery backup are available to meet certain customer needs. Most commonly used in situations where a conventional power source isn’t practical or available, solar-powered cameras operate by charging a battery via a solar panel during the day, allowing the camera to function at all hours.

Solely battery-powered cameras, while in the truest sense of the word are not yet considered to be surveillance cameras, still have found a place in the security industry. Most often motion-based, these cameras will record a few seconds of video upon sensing an intrusion (or other designated event). Once recorded, the cameras send video to a designated destination, such as a control panel. However, one company — RSI Videofied — is about to change the way we think about battery-powered cameras. A streaming wireless battery camera is in the works from RSI Videofied — the StreamingViewer — and is scheduled to ship sometime in 2015.

No matter how one thinks of wireless, it’s a growing trend that’s here to stay. More consumers are coming to expect wireless capabilities from the technology they purchase, and it’s up to dealers and integrators to meet those expectations.


Wireless Video: Pros & Cons



High Resolution

Depending on the camera, images displayed with a resolution of up to 20 megapixels, offering greater clarity and detail.


Wireless cameras are limited by the distance from which they can be from a signal-receiving device.

Flexibility and Installation

Because they are easily installed and removed, wireless cameras offer more flexibility if there ever comes a time that the camera needs to be repositioned. Requiring only a means of power, lengths of cable need not be run during the installation of these cameras.

Signal Interference

With a number of environmental changes that could affect the signal, such as other devices and physical barriers, the risk is greater when compared with wired cameras.

Remote Access

When connected to the Internet, users can view video and manage the system through PCs and other connected devices.

Bandwidth Issues

Because of the heavy bandwidth usage, video is rarely able to be continuously transmitted. Instead, most wireless IP cameras make use of video analytics to only transmit the events for which they’re programmed.


A Survey of Wireless Technology Products

These products are broadening the scope of what it means to be ‘wireless.’ Featured here are a variety of video devices that bear this title, either through the way the device is powered or transmits video. Or, in the case of one such product, both. Read on to see how these companies’ products are making waves.
