Network Video Servers / IP Video Servers
Network video servers, also known as IP video servers, turn any CCTV camera (with a standard BNC output) into a network security camera (Ethernet/CAT-5 output). The purpose of a network video server is to translate the analog signal from CCTV cameras into a digital and IP based video stream capable of being broadcast over an IP network. IP video servers have built in software that allow users to connect to their cameras through a standard Internet Explorer web browser. Some video servers also allow you to connect to your camera using NVR software (network video recording).
Our Geovision IP video server is compatible with Geovision NVR software. The Zavio network video server that we supply is compatibe with our NUUO network camera software. The above screen shot shows an Internet explorer view of the 4 IPVS-MJ1 IP Video Servers connected to 4 outdoor analog security cameras. Unlike the Zavio V1100, the IPVS-MJ1 is not compatible with any 3rd party IP camera software which is why we recommend the Zavio IP server over it unless the customer is just looking for a very basic one camera surveillance system to monitor over the Internet.

A network video server, also known as an IP video server, is a very handy piece of hardware for any surveillance system installer to be familiar with. Below we will describe a few different types of surveillance applications that these servers can be used in.
Network Video Server Application #1Surveillance Application Example #1 Requirements: In this example, the customer wants to view a single camera over the Internet using Internet Explorer. The customer wants a good quality outdoor / weatherproof camera with infrared / night vision capability. The customer is more interested in the live viewing. Recording the video is not a priority and if it is done, just basic recording features are needed.
Surveillance Application Example #1 Solution: CCTV Camera Pros would first recommend the appropriate outdoor IR security camera. The camera would connect to the network video server using coax cable and BNC connectors. The network video server would connect to the customer's network router which would in turn be connected to a high speed modem or some kind of existing high speed network. This would make the IR security camera accessible for live viewing over the local network and could also be viewed remotely over the Internet if the appropriate port forwarding and firewall rules were configured.
Network Video Server Application #2
Surveillance Application Example #2 Requirements:
In this example, the customer has a facility with two separate buildings. The customer would like to have security cameras installed in both buildings and have a single recorder record the cameras in both buildings. The customer would also like to view all cameras from both buildings remotely over the Internet. The customer has high speed Internet access at both buildings and both buildings share the same local area network.
Surveillance Application Example #2 Solution: CCTV Camera Pros would recommend using a hybrid digital video recorder capable of supporting both CCTV cameras as well as IP cameras and IP video servers. Either the Geovision or NUUO hybrid DVR/NVR systems would work well. If the system would expand past 16 cameras, then the NUUO NVR system would be recommended, as it can support up to 64 security cameras.
The building with the most cameras would be the chosen location of the DVR. The cameras in the building with the DVR would be hard wired to the DVR using RG59 coax cable or BNC plug and play cables. Each camera in the remote building (where the DVR is not located) would be connected to a video server. Each video server would be connected to the network switch located in the remote building. Each video server would be assigned a unique local IP address. The DVR located in the other building would be able to access each of the remote cameras using the IP addresses of it's corresponding video server. All cameras would now be managed and recorded by the central DVR / NVR, and because the DVR has a build in web server, all cameras can be accessed remotely over the Internet or over the local area network on one central screen / system using the Internet Explorer web browser.
