What is IP-Surveillance:
IP-Surveillance is a term for a security system that gives users the ability to monitor and record video and/or audio over an IP (Internet Protocol-based) computer network such as a local area network (LAN) or the Internet. In a simple IP-Surveillance system, this involves the use of a network camera (or an analog camera with a video encoder/video server), a network switch, a PC for viewing, managing and storing video, and video management software.
Because of the digital nature and method of video distribution, IP-Surveillance provides a host of benefits and advanced functionalities that gives you greater control and management of live and recorded video, as well as alarm events. This makes the system highly suited to security surveillance applications. The advantages include:
- Remote accessibility: You can access live and recorded video at any time and from virtually any networked location in the world. Multiple, authorized users at different locations may be able to access live or recorded video. This is advantageous if your company wants a third-party, such as a security firm, to benefit from and have access to the video. In a traditional analog CCTV system, you need to be in a specific, on-site monitoring location to view and manage video, and off-site video access would not be possible without some additional equipment, such as a video encoder or a network DVR (digital video recorder).
- High image quality: High image quality is essential in a security surveillance application. You want to be able to clearly capture an incident in progress and identify persons or objects involved. In a network video system, the quality of images produced can be more easily retained than in an analog surveillance system. With an analog video system, the captured images are degraded with every conversion that the images make between analog and digital formats and with the cabling distance. The further the analog video signals travel, the weaker they become. In a fully digital IP-Surveillance system, images from a network camera are digitized once and they stay digital with no unnecessary conversions and no image degradation due to distance traveled. In addition, digital images can be more easily stored and retrieved than is the case with the use of analog video tapes. A network camera that uses progressive scan technology provides clearer images of moving objects because the whole image is presented at one time. With an analog video signal, two consecutive interlaced fields of lines are presented to form an image, and when displayed on a PC monitor, blurriness occurs when objects move between the image capture of the two interlaced fields. A megapixel network camera (i.e. one that delivers an image comprised of 1 million or more pixels) can also offer resolutions greater than what an analog camera can offer, which means that more detail or larger areas can be covered.
- Easy, future-proof integration: Network video products based on open standards can be easily integrated with computer and Ethernet-based information, audio and security systems, video management and application software, and other digital devices. For instance, a network camera can be linked to specialized software programs that could, for example, integrate video with a Point of Sales system, or analyze the visual and/or audio data to detect wanted persons in a crowd or unauthorized access to specific areas.
An IP-Surveillance system can be as simple or as sophisticated as your needs require. In a simple scenario, you have a PC where you want to view and record video. You have an Ethernet cable between a PC and a network switch (which allows different devices to connect to each other and share, for instance, a common Internet connection) and a cable from the switch to the camera location. You then need equipment that can capture video and send a video stream over the network. This can be a network camera, or an analog camera connected to a video encoder (also sometimes known as a video server).
A wide variety of network cameras and video encoders are available. Network cameras range from fixed cameras and fixed domes, to pan/tilt/zoom (PTZ) and PTZ dome cameras, and may be designed for use indoors or outdoors. Other network camera features include built-in support for wireless communication, megapixel resolutions and vandal resistance.
There are many ways to design and secure a network for IP-Surveillance. In addition, a network can be as small or as extensive as your requirements, and it can be wired, wireless or a combination of both. It is also easy to increase the bandwidth capacity of your network simply by adding switches/routers. And different technologies can be used to optimize bandwidth usage. Furthermore, a wired network can deliver not only data, but also power using Power over Ethernet (PoE) technology. This simplifies installation of PoE-enabled network cameras/video encoders and provides cost savings.
The hardware requirements of an IP-Surveillance system are not complex. Simply use standard components found in the IT industry. Today's PC, with a Pentium processor and Windows operating system, is able to run a video management software, and record and store video from up to 50 cameras.
A wide range of software is available to help you in the preparation, installation and management of an IP-Surveillance system. For example, you can use the Design Tool, which helps you estimate how much bandwidth your network video system will require, and installation software such as the Camera Management, which makes it easier for you to find, install and configure the video products on the network. A video management software is also recommended. It will allow you to, among other things, centrally manage and configure the network video products to your viewing, recording and security preferences.
