Wireless Public Sector CCTV
Sunstone » » Wireless Public Sector CCTV
The UK has more CCTV cameras per capita than any other European country, and CCTV for public space surveillance in the UK has developed at a faster rate than anywhere else in the world.
So no longer are we facing the question: Why do we need CCTV? It’s more: What is my local authority doing to ensure public safety in this economic downturn, plagued with budget cuts?
This is where emerging technologies present a compelling case. The benefits of IP solutions over historic analogue systems will only be further enhanced and documented in 2013, and wireless CCTV solutions should really come to the fore.
With wireless public-space CCTV, long gone are the days of massive investment with depreciating assets. The latest surveillance technologies present a wealth of cost savings, superior quality footage, enhanced storage and review capabilities, and truly scalable solutions.
Rapid deployment and redeployment
Wireless CCTV cameras can be deployed and redeployed quickly and efficiently, which is the polar opposite to fixed analogue cameras that require a dig solution.
Deployment and redeployment of cameras can be configured in days. Such time savings greatly benefit emergency services, enabling them to target crime hotspots and monitor temporary events that possess an element of public risk. Moreover, with wireless technologies, the police and local authorities can share services and cameras, presenting an even greater cost saving.
Wireless cameras can be gradually introduced and added to existing systems to create a hybrid solution. An evolutionary approach to migration negates the high up-front costs associated with analogue systems. Moreover there is no mass ‘rip out and replace’ required.
Indisputably, a wireless HD camera can deliver better image quality and higher resolution than an analogue camera. In a fully digital wireless surveillance system, images from a network camera are digitised once, and they stay digital with no unnecessary conversions and no image degradation. In addition, digital images are stored and retrieved much more effectively.
Wireless surveillance solutions also support two-way audio, allowing users to listen in on an areas as well as playback a recorded audio clip to visitors or intruders remotely. Audio detection can also be used as an event trigger, which, for example, can be used to direct a PTZ network camera or initiate recording of video — all automated and managed wirelessly.
The aforementioned swift and cost-effective deployment is illustration enough as to why a wireless CCTV solution is most appropriate to monitor an event.
Advanced wireless cameras include built-in features such as video motion detection, audio detection alarm, active tampering alarm, and alarm and event management functionalities. These features enable the surveillance solution to constantly analyse inputs to detect an event and to automatically respond.
Efficient storage delivers obvious benefits in terms of hardware requirements. In addition smart storage is also more flexible in video format, with wireless and IP cameras offering more than one video compression format, including Motion JPEG, MPEG-4 Part 2, and H.264.
Edge storage allows a wireless camera to record video directly to a storage device such as an SD/SDHC card, thereby creating a more robust, reliable, and flexible system.
The cameras can record video locally when the central system is not available, or continuously record in parallel.
A wireless surveillance system can change and grow, almost immediately, as situations and requirements dictate. Cameras can be added and/or moved within the system without significant or costly changes to the wireless infrastructure and no service interruption.
Wireless surveillance solutions are much less expensive alternatives than traditional coaxial and fibre cabling for an analogue CCTV system. In addition, digital video streams can be quickly and swiftly viewed in various locations and also seamlessly integrated in to an intelligent control room.
Management and equipment costs are also lower with the adoption of back-end application, smart storage, and open systems-based servers as opposed to proprietary hardware, such as a DVR in the case of an analogue CCTV system.
Wireless CCTV solutions offer a myriad of benefits from cost savings to smart storage and enhanced images and will no doubt be on the agenda for many local authorities. They should play a key role in shaping the future of public-space CCTV.
