Select the Network Cameras, network video server?
Network Cameras and network video servers are the core of the network video monitoring system equipment, network monitoring project design, in the end select IP Camera, network video server?
First of all, we should understand the difference between Network Camera and network video servers:
The IP Network Camera is the video server with analog cameras integrated into the whole, directly plug the Internet cable will be able to use. Types of IP Camera, the style is very limited, the selective far less than the analog cameras.
Network video server without the camera, but its flexibility that can be connected to any analog camera. The video server of the multiplexer can be connected a plurality of cameras.
Our choice, it is necessary to consider the function and effect, should be considered to facilitate sexual, but also consider the capital.
1, if there is more than one monitoring point, the location of the monitoring points is relatively close, you can consider the use of multi-channel network video server + analog camera program, the total cost is lower than the direct use of multiple IP Network Camera but to pay attention to the resolution of the multi-channel network video server slightly lower than the single-channel video servers and Network Cameras, user requirements are not very high, generally acceptable.
Scenario 2, if there are no special requirements for style camera, IP Camera style you need, then use the appropriate style Network Camera either directly, can also be used a network video server + analog cameras.
3 camera style special requirements, one machine To infrared zoom, low-light cameras, riot cameras, it is necessary for the network video server + analog camera solutions.
Note: a monitoring system, a unified series of IP Network Camera and network video servers, can be mixed. Different series, different brands of Network Cameras and network video server, generally can not be mixed.
