11 practical tips of video surveillance system integration

How to choose Access Switch?

For more than 8 cameras, please use a pure Gigabit network switch. The actual bandwidth of the switch we use is 50%-70% of the theoretical value, so the actual bandwidth of a 100M port is 50M-70M. It is recommended that a gigabit access switch be maximum access to 12 720P network cameras. At the same time, considering the current network monitoring using dynamic coding mode, camera code flow peak may exceed 4M bandwidth, while considering bandwidth redundancy design, so you should use Fast Ethernet Switch to for 8 units camera, and use Gigabit Switch if more than 8 units camera.

Set up IP address in advance

Before construction, you should modify and register the IP addresses of all Network Camera, NVR, Computer master control machine, storage server, streaming media server, HD decoder, Management Server, and must pay attention to avoid and local network devices (such as computers, network printers) have IP address conflict. The address of all equipment must be recorded, the IP address of the camera must be marked on the drawing, convenient after-sale staff maintenance.

The IP address of all network dome cameras, network cameras, NVRs, computer hosts, storage servers, streaming media servers, high-definition decoders, and management servers in this system should be modified and registered. The original network in the local network (such as computers, network printers) have IP address conflict. All the equipment IP address to be recorded, the IP address of the camera should also be marked on the drawings to facilitate the maintenance of after-sales staff.

How to choose a converged switch?

IPC to the front-end switches can be used Cat5 network cable, and front-end switches to the main room between the switchboard must use the national standard Cat6. We are now most choose optical fiber transmission, single-mode and multimode.

The choice of network cable

IPC to the front-end switches can be used between the national standard Cat5 cable, the Cat6 network cable is also gradually applied to the security system.

How to choose Core Switch?

You should choose the big brand of all gigabit switches, and must not be loaded work with them, such as 24-port full Gigabit switch in practice not to use more than 20 port, because the network HD monitoring data volume is relatively large and is constantly transmitting data, the processing requirements of the switch is relatively high, If there is a switch with a lot of points when the delay, cotton phenomenon, you can try to add a switch to solve the problem.

As for routing function of the core switch, according to the need to choose.

Monitoring range

For different coverage areas can use a different number of high-definition network camera type and HD network camera. (1 / 4Sensor) / 2MP (1 / 2.7Sensor) / 3MP (1 / 2.5Sensor), in a project, the lens selection is very important, it depends on whether the Customers need to watch the full coverage of the range.

Monitoring object

The monitoring object determines the framing range, the camera position and the type of camera required, and the monitoring object has a fine map and a general view. Subtle images are effective for identifying people or specific targets, such as people’s faces, documents, sales store monitoring; general observation is mainly to monitor the entire scene or the scene about the flow of the situation. The monitoring target determines the framing range, the camera position, and the type of camera you want.

Monitoring environment

Because the indoor and outdoor light is not the same, so we have to consider the sensitivity and lighting effects. Outdoor environment can be used infra-red light, some also need to use day and night surveillance cameras, if it is indoors that generally do not have to consider so much, as long as the lighting effect is good. In addition to outdoor, it also has to consider dust, moisture, waterproof, damage-related factors. For example, in the dark environment, the camera can use a low illumination function, in the uneven light distribution of the environment can be used a wide dynamic camera, in the card mouth environment can be used for professional license plate function camera, elevator environment can be used for special cameras and so on.

Hidden monitoring

Because some places take into account some specific reasons need to install a hidden million high-definition network camera. So in this regard have to consider the choice of non-hidden or covert installation of the surveillance camera.

Data encryption Security

Some need to consider the encryption of HTTPS encrypted over the network, allow or deny access to IP address filtering, and control network access IEEE802.1X, IPV6, and wireless functionality. Of course, these functions are not used in the general case.

Monitor audio function

This also needs to consider where you use it, if you need to use audio-enabled million HD network cameras, it must also be considered to connect headphones or speakers, pickups and so on equipment. For example, the application of electronic exam monitoring system on campus.
