Over the years there have been two distinct trends that have combined to boost the video surveillance or monitoring market evermore into the forefront of discussions. The first has been the rise in terrorism, vandalism, refugee populations crossing borders and additional global turmoil. The second trend has been the advancement in video camera technology – from analog NTSC or PAL standard definition video formats to IP based cameras supporting full frame rate (30fps) 1080p HD video. The technology behind video security has progressed significantly in the last 10 years. With these new resolutions has come advanced technology, functions that were not possible before or were only available off a server in the central monitoring station are now done routinely, often in the cameras themselves. This refers to features such as facial recognition, automatic license plate readers, automatic red light cameras and more. What all these new smart, HD video cameras need is connectivity. Most of these applications require outdoor cameras While all these applications may seem to be unique, there are a few things all of them have in common. First, these deployments and features require good to excellent video definition quality. Standard definition is no longer acceptable, and running at 10 frames per second vs. a full rate of 30fps, is not acceptable. Second, almost universally these applications will have a high percentage of cameras being deployed outdoors, where the environment is harsh, units are unguarded and connectivity is seldom available. For video security the camera needs to be placed where it can perform it’s desired function, and not where there is a convenient fiber or Ethernet cable handy. Having a fiber strand within 10 feet of the desired location of a camera is not much better than being a mile away. It still requires permits, right of way negotiations and some level of digging. Market With all of these factors combined, the wireless video surveillance market is forecasted to reach $1 Billion in 2019. These numbers do not address the latest shifts in the video security market being driven by orthogonal applications. For example, cities deploying intelligent traffic systems use wireless to connect signaling lights in intersections. In many cases the decision is made to add a camera to the deployment, using the wireless network to support both the signaling traffics as well as the video traffic. When carriers or municipalities decide to deploy public Wi-Fi or hot spots, increasingly the request is bundled with a desire for adding a video camera to the hot spots deployment. Video security requirements With the need and growth for video surveillance, and in particular wireless video surveillance established, what are the specific requirements for this application? What requirements must a viable video security solution provide? These requirements can be broken down into those that apply to the cameras themselves, and those that apply to the wireless network component providing the connectivity. Video security requirements for wireless networks With the need and growth for video surveillance, and in particular wireless video surveillance established, what are the specific requirements for this application? What requirements must a viable video security solution provide? These requirements can be broken down into those that apply to the cameras themselves, and those that apply to the wireless network component providing the connectivity. Video security requirements for wireless networks High capacity – up to 25 Mbps per cameras. Reliable video communications – the network must have high availability (as much as 99.999%) and be secure. Mobility. Water- and dust-proof (IP67-rated). Wide operating temperature range -40° to 55°C. Video security requirements for the cameras Complex and constantly changing lighting. Complex picture composition, backlighting. Large area overview. High level of detail needed. Vibration. Clear images of rapidly moving objects and persons. When it comes to throughput or capacity requirements, these can vary a great deal based on resolution, frame rate and even the device being used to view the video streams. In this case the device is typically a large monitor in a central location. Table below gives some idea of capacity per camera requirements. From the table it can be seen that to provide an HD video stream at 720p, a common resolution, the network must support at least 2Mbps and ideally 8Mbps. When this is multiplied out it can be seen that a good security camera will require on the order 700Gb per day. Wireless video security and Proxim When looking at each of the wireless network requirements, it is clear that the Proxim Wireless Tsunami® product line delivers on all of these, and does so with features and functionality that meet and exceed the needs described here. High capacity With a typical security camera consuming up to 8 Mbps, to be effective the wireless network will likely be supporting more than one camera per network. Proxim offers a variety of Tsunami® products that support 10Mbps, 25Mbps, 50Mbps, 100Mbps, 240Mbps up to 633Mbps of useable bandwidth. Reliable video communications There are three main factors to reliable video communications: The network must have high availability (as much as 99.999%) The Tsunami® product line of outdoor wireless networking systems offer a full two year warranty. Proxim has customers who have deployed radios from ten years ago, have never been touched, and are operating today. With an field determined MTBF of well over 1 million hours for some product lines, up to over 2 million hours of MTBF for others, this equates to 1.5 to 3 seconds outage per year. The network must ensure the quality of the video stream in the face of radio frequency impairments or other traffic being carried on that wireless link In this application poor image quality is absolutely not allowed. It is no exaggeration to state that in many deployments lives are at stake, and the video system and in particular the network must be top quality. From a radio frequency performance perspective, Proxim builds into every unit it’s suite of interference mitigation technologies known as Proxim ClearConnect™ ensuring reliable wireless connectivity.
