Big sporting events, political conventions, conferences, and summit meetings are all temporary events that very often require the deployment of a temporary video-surveillance system to protect the event and its attendees. Crime scenes are also locations that require a temporary video-surveillance system, in order to provide tactical support to law enforcement or military personnel. There are multiple challenges in designing an effective temporary video-surveillance system, however, because many of the technologies used in permanent deployments are too slow to deploy for an event that lasts only a few days or in a crisis situation that requires an immediate video surveillance system be put in place.
In this post, I’d like to go over the key components of a temporary video-surveillance system based on our experience with many temporary CCTV deployments for large-scale events as well as for law enforcement and military applications.
– Camera Technology: In terms of cameras, PTZ cameras are deployed most often for temporary video-surveillance systems. Fixed cameras require more planning to determine the correct zoom lenses and field of view and they are less flexible that PTZ cameras. PTZ cameras, on the other hand, can be easily moved around and reused for multiple temporary events. Moreover, if there is a need to change the camera’s field of view in a temporary video-surveillance systems, PTZ cameras make the change simple and immediate with no need to physically reach the camera.
– Video Transmission Technology: Most temporary video-surveillance systems are wireless and leverage wireless transmission to stream video from the CCTV cameras to the main control room. Point-to-point wireless links, point-to-multipoint networks and mesh networks are all very common wireless technologies for temporary video-surveillance systems. Wireless links can be deployed in mere hours without any need to trench and wire the site. Wireless video-surveillance system can also be easily deployed to a different event once a specific event is over. Wired transmission. on the other hand, requires an investment that is mostly lost once the temporary CCTV system is removed. Point-to-point wireless links are ideal for smaller temporary video-surveillance systems, while point-to-multipoint wireless networks and wireless mesh networks are the suggested wireless technologies for more complex temporary video-surveillance deployments.
– Power Technology: Power tends to be pervasive in urban areas and, therefore, a good portion of temporary video-surveillance systems don’t need any solar or battery technology in order to operate. However, certain locations may require a significant investment to be wired up and power the cameras and the wireless Ethernet radios. Consequently, solar panels and battery power can be the most cost effective approach to building a stand-alone solar-powered temporary video-surveillance system.
– Mounting Technology: Temporary video-surveillance systems that are installed only for a few hours or days are often deployed using telescopic masts and they’re often mounted on tripods and trailers. Tactical CCTV systems for SWAT operations or covert criminal investigations leverage law enforcement vehicles to be deployed. Military temporary video-surveillance systems often used military trailers that can be moved around by military vehicles.
Fluidmesh has been involved in many temporary wireless video-surveillance systems. Outdoor wireless networks are very commonly used when a video-surveillance system is temporary and it will be removed after a few weeks or days. Therefore, temporary CCTV is a critical area of expertise for Fluidmesh and for our wireless network design team.
We have been involved in providing our wireless technology for the temporary video-surveillance systems for some leading political conventions such as the Democratic National Convention three years ago and the Republican National Convention six years ago. Moreover, our wireless technology has also been used for wireless temporary video-surveillance systems for major sporting events such as the Super Bowl a year ago, Boston Marathon and the US Open in New York City in 2015.
Temporary video-surveillance systems can also be used for tactical applications by law enforcement agencies, as well as for covert temporary video-surveillance during criminal investigations and in military operations. For example, we have been involved in providing our wireless mesh networks for SWAT teams that need to deploy a temporary video-surveillance system during hostage situations, to European law enforcement agencies deploying covert video-surveillance systems during investigations against organized crime, and to the US Army during operations in Afghanistan with temporary video-surveillance cameras mounted on military trailers.
