This offers a cleaner, tidy installation process. Usually, these are more reliable as they are not subject to interference from wireless signals. Wireless CCTV works by connecting to your Wi-Fi network and transmitting security footage from your camera to your recording device.
You may access the captured footage by using a built-in device or cloud storage which will allow you to watch from anywhere with an internet connection. As they connect to your Wi-Fi, the installation process is quick and smooth in comparison to wired CCTV. This is ideal if your business is operating in a temporary location as they are easy to set up, move or take down. However, these systems still require a wired power cable. You will need to bear this in mind when choosing a location for mounting. At ClearView Communications, we proudly work with a number of security service partners:.

Speak to your engineer upon arrival to ensure you receive the bespoke installation you require. Next, it will be up to you and your colleagues to select the prime locations for your cameras. The engineer will help ensure that the cameras are not hindered by reflections or blind spots. In addition, you must be careful not to breach the privacy of any neighbouring buildings. Let them know about the CCTV installation in advance so that they are aware. It is illegal to record audio on CCTV in the UK, so make sure audio is disabled on your devices. If you are capturing footage outside of your private property, you need to take certain steps to comply with data protection laws.
For example, if you wish to record the public footpath outside your premises, you need to put signs up to state that recording it taking place and why. Lastly, make sure that only authorised individuals have access to the footage e. security staff and the CEOs. If recordings enter the wrong hands, you could be in breach of the data protection act. Add an extra layer of security by protecting the footage with a secure password. The cost of your CCTV installation is entirely dependent on the size of your business and the level of detail you wish to capture. Naturally, the more cameras you install, the higher the cost. CCTV surveillance systems can have a great impact on your business, whether you are small and local or a large corporation.

There really are no fixed rules or "one size fits all" solutions when it comes to network design. However when faced with complex network design, understanding the key network design considerations will help you identify the most important components which you will need to focus on, in order to tackle the complexity of the network and design a solution that will meet those key design considerations.
Tiziana Catarci. Abstract This article discusses an innovative system for traffic management that is presently under installation in the city of Valencia. Key features of the system are to exploit open source software components and use MPEG-4 video streaming over an Internet protocol. The video streaming management is particularly sophisticated, resulting in a flexible, efficient, and reliable service. Another important element is the communication network design. Akram Khan.

Approach In this paper, we will first describe a typical customer scenario for an IP-based video surveillance system in an airport facility. We will complete a network design for this hypothetical system, and use this case study to illustrate the key network considerations and design concepts involved in creating this network. This document focuses on the network itself, so component descriptions, video or storage product selection, storage design, video management software planning, video related technology, etc. are beyond the scope of this document. Ethernet, LAN, switching and routing technology, etc. Then, a proposed network design is presented. Different network considerations are raised and explained in detail. The cameras are installed at 6 airline terminals and one administration building.
Network recovery time must be below 50ms should there be any network device failures or broken links. Videos are archived 24 hours a day, days a year. The network design should take into considerations and accommodate this growth rate. Every workstation can simultaneously monitor monitor up to 16 live video streams captured from any local cameras. The video format is 4CIF D1 , H. Each workstation can simultaneously monitor up to 16 live video streams captured from any camera in the administration building. Every analog camera shall be directly connected to one video server for video digitization and compression. There are 4 to 5 cameras in an average cluster. Key design considerations are described in the following section.
Network requirements should be clearly communicated and well defined before a network design starts, though in some cases a network designer needs to clarify additional details along network design process. Network requirements are also the benchmark to measure the success of the network design against. With a clear understanding of the relationship among cameras, video zones, terminal and administration building, a structural view can be drawn as shown in Figure To cope with changes effectively, the network must be scalable. A flat or collapsed network may appear simple, but it is difficult to scale and manage.
Within the group, networking services like switching, routing, redundancy, security, traffic prioritization, etc. can be planned and deployed accordingly. It is the backbone of the network. More network transmission control is implemented at this layer, like VLAN, filtering. Redundancy and routing are implemented too. Switching functions are implemented along with administrative policy, such as security, traffic prioritization. In the case of AIA, the entire network should be able to transport data traffic among cameras, workstations and servers. CCTV camera quantities and locations are listed in Figure These cameras capture video and send video data over the network for viewing and archiving. The location and quantity of workstations and servers are listed below.
The location of each AIA network element in this three-layer structure is illustrated in Figure Access Layer: The layer provides network access to all cameras and transports video streams to Distribution Layer. No matter what topology you opt for, the most important consideration is how to achieve high network availability. A highly available network minimizes the impact to business applications from a single point of failure in the network, regardless of whether the failure is caused by a link, component in a network device or network device itself. To improve network availability, normally additional links or network devices are introduced to create redundancy. In an Ethernet layer 2 network, redundant links sometimes cause loops which results in a serious downgrade to network performance, or even a halt to network operations in the worst cases. There are IEEE standard Ethernet protocols that deal specifically with redundancy. IEEE It can be implemented on many different topologies and is widely deployed in many systems.
Though the protocol greatly improves network recovery time, it still may take up to several seconds to converge when there is a network link status change. To provide network redundancy solution to many industrial applications which require sub-second network recovery time, some industrial Ethernet switch manufacturers have developed proprietary protocols, mostly using ring topology. It is built on a physically looped topology, ring. In Turbo Ring see Figure , a Master switch is either manually assigned or automatically detected. The master switch disables a port on the ring, making the ring logically a bus topology. The redundant link connecting to the blocked port serves as backup path; it does not transport data. When there is a link or device failure in the ring, the backup path becomes available again.
The network recovery process takes less than 20ms for a network with devices; excellent performance that meets industrial requirements. There are three topology options: Ring Coupling, Dual-Ring, and Dual Homing Figure to A customer can choose the best fit option based on specific network redundancy requirements and deployment or cabling costs. Turbo Chain is easy to configure by linking two user-configured end ports within the same network segment. In addition, Turbo Chain supports standard IEEE In this case the limitation and bottleneck is occurring in the STP portion of the network, not Turbo Chain.
The best results are achieved by hooking up Turbo Chains to networks that also possess fast recover time, such as Turbo Rings. When combining Turbo Ring and Turbo Chain together, say Turbo Ring in the core network and Turbo Chain in the distribution or access network, the network recovery time will be less than 20ms. The combined technology provides the greatest flexibility in designing a highly redundant network and best network performance.
