What is an analog video converter/server?
A video server digitizes analog video signals and sends digital images directly over an IP network, such as a LAN,wireless network (wi-fi), intranet or Internet. It essentially turns an analog video system into a network video system and enables users to view live images using a Web browser or a video management software on any local or remote computer on a network. It allows authorized viewers from different locations to simultaneously access images from the same analog camera, as well as network cameras if they are added to the system.
Analog Video Converter FAQs
What is a video server?
A video server digitizes and compresses analog video signals and transmits the video over an IP network, such as a LAN, WAN, intranet or the Internet. It enables users to record and/or view live surveillance images using a Web browser or video management software on any local or remote computer on the network. Simply put, a video server turns an analog camera into a network camera. In addition, video servers allow a wide variety of analog cameras, including pan/tilt/zoom, dome, miniature or microscopic cameras, to be controlled over the network, or even across the Internet.
Why do you need a video server?
Video servers allow security managers to retain analog CCTV cameras while building a surveillance system that in all other aspects is a network video system. A typical scenario is when an organization has an analog CCTV surveillance system installed. The company recognizes the benefits of network video and makes a migration plan from the analog system to a new network video system. Video servers constitute a way to migrate step by step by first using them to access analog cameras over the network and replacing old video recording and management equipment – typically a DVR (Digital Video Recorder) – with a network video solution. As the analog cameras become obsolete, they can be replaced with network cameras.
What is the difference between a video server and a video encoder?
There is no difference. The names are interchangeable and are used for the same type of product.
What is a video server blade version?
A video server blade version is a video server without a casing. The blade version essentially consists of a circuit board and all the necessary input and output connectors. A video server blade version cannot function on its own; it has to be mounted in a rack to operate.
Why do you need a video server blade version?
For large video surveillance installations, hundreds of analog CCTV cameras may need to connect to the network video system. In such numbers, stand-alone video servers would quickly fill up a room. Blade versions can fit in standard racks, taking up considerably less space.
What is a video server rack?
A video server rack is a chassis that allows video server blades to be mounted in a standard-sized rack, normally 19 inches wide. Video server racks offer functionalities such as an integrated Ethernet switch and hot swapping of blades – i.e. blades can be removed or installed without having to power down the rack. Racks can be of different heights, typically 1U (1 unit = 1.5”) or 3U (3 units = 4.5”).
Why do you need a video server rack?
The main reason is that video server racks save precious space when installing many video servers. In addition, racks can provide a number of capabilities that save expenses and simplify the maintenance and upgrading of the system.

What is a network video decoder?
A network video decoder is an inverted video server. It converts digital video and audio streams into analog signals, which can then be used by regular TV sets, analog monitors and analog video switches.
Why do you need a network video decoder?
As for video servers, network video decoders are normally used when the user wants to retain some analog equipment to monitor or relay analog signals. The network video decoder allows these products to be used in a network video surveillance installation. A typical case could be in a retail environment, where the user may want to have traditional monitors in public spaces to demonstrate that video surveillance is used. A network video decoder would be used to connect such monitors.
What video management software work with video servers?
A fundamental advantage of network video systems is the wide range of installation and video management software one can choose from since network video is based on standard interfaces and protocols. Video servers open up the possibility for analog CCTV systems to use and take advantage of the variety of application software
What is the difference between a DVR and a video server?
A DVR (Digital Video Recorder) enables an analog CCTV system to record and store video digitally instead of using tapes. Some DVRs include a network connection allowing images to be transported over the network and monitored from PCs. An analog CCTV system using a network DVR is therefore a partly digital system. Adding video servers, however, creates a true network video system where all video is transported over an IP network. The advantages of using a video server include the use of standard hardware for video recording and management, the possibility to record and store video off-site, and creating a scalable and future-proof system.
