The digital, network video surveillance system provides a host of benefits and advanced functionalities that cannot be provided by an analog video surveillance system. The advantages include superior image quality, remote accessibility, distributed intelligent video capabilities, easy installation and integration, and better scalability, flexibility and cost-effectiveness
Image quality is clearly one of the most important features of any camera, if not the most important. Superior image quality enables the user to more closely follow details and changes in images, making way for better and faster decisions to more effectively safeguard people and property. It also ensures greater accuracy for automated analysis and alarm tools. Axis network cameras provide high-quality video images, and megapixel and HDTV network cameras are available to provide even more image details.
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 over a network. In addition, digital images can be more easily stored and retrieved than in cases where analog systems are used.
Easy, future-proof integration
There are almost no limitations as to where a network video product can be placed. Axis network video has the capacity to provide a high level of integration with other equipment and functions, making it a continually developing system. A fully integrated Axis network video system can be used for a multitude of applications simultaneously: for instance, access control, building management, point-of-sales systems, ATMs, as well as fire alarms, intruder and visitor management. An analog system, on the other hand, rarely has an open interface for easy integration with other systems and applications.
A network video system can grow with a user’s needs—one camera at a time, while analog systems can often only grow in steps of four or 16 at a time. IP-based systems provide a means for network video products and other types of applications to share the same wired or wireless network for communicating data. Video, audio, PTZ and I/O commands, power and other data can be carried over the same cable and any number of network video products can be added to the system without significant or costly changes to the network infrastructure. This is not the case with an analog system. In an analog video system, a dedicated coax cable must run directly from each camera to a viewing/ recording station. Separate pan/tilt/zoom (PTZ) and audio cables may also be required.
Network video products can also be placed and networked from virtually any location, and the system can be as open or as closed as desired. Since a network video system is based on standard IT equipment and protocols, it can benefit from those technologies as the system grows. For instance, video can be stored on redundant servers placed in separate locations to increase reliability, and tools for automatic load sharing, network management and system maintenance can be used—none of which is possible with analog video.
Based on open standards, Axis network video products run on IP networks. Using standard PC server hardware rather than proprietary equipment such as DVRs radically reduces management and equipment costs, particularly for larger systems where storage and servers are a significant portion of the total solution cost. Additional cost savings come from the infrastructure used. IP-based networks such as LANs and the Internet can be leveraged for other applications across the organization.
A network video system may also provide insights into ways of improving a business. For example, in retail applications, implementing network video analytics may help improve customer flow and enhance sales.
Distributed intelligence
These days, a massive amount video is being recorded, but never watched or reviewed due to lack of time. As a result, events and activities are missed, and suspicious behaviors remain unnoticed. With network video, intelligence has been brought into the camera itself.
Axis network cameras and video encoders have built-in features such as video motion detection, audio detection alarm, active tampering alarm, I/O (input/output) connections, and alarm and event management functionalities. These features enable the network cameras and video encoders to constantly analyze inputs to detect an event and to automatically respond to an event with actions such as video recording and sending alarm notifications. Other unique features include audio detection and active tampering alarm. Axis network video products also offer AXIS Camera Application Platform which allows download and installation of third-party applications such as people counting and heat mapping.
With network video, users can access real-time video at any time from any authorized computer anywhere. Axis network video products provide an easy way to capture and distribute high quality video over any kind of IP network or the Internet. The video can be stored at remote locations for convenience and security, and the information can be transported over the LAN or Internet.
Easy, reliable installation
An IP surveillance system is fast and easy to install. Axis network cameras and encoders offer Power over Ethernet support, which simplifies installation since only one cable is needed for power and video. Products that are vandal-resistant and out-of-the-box outdoor-ready further speed up installation and ensure excellent video images even in the toughest conditions.
Digital pan/tilt/zoom, remote zoom and remote focus enable convenient adjustment of the camera’s angle of view and focus over the network from a computer. Axis Corridor Format allows the installer to mount the camera in the most effective way for the situation at hand, and the pixel counter helps the installer verify that the system fulfills any regulatory or specific customer requirements. To further facilitate easy installation and configuration, Axis offers a number of free software management tools, such as AXIS Camera Management.
