1, 5 or more points (including 5 points) must use the full Gigabit network switch 2. Before the construction, the IP addresses of all network domes, network cameras, NVRs, DVRs, computer servers, and high-definition decoders in the system must be used. For unified revision and registration, we must be careful not to have IP address conflicts with existing devices (such as computers or network printers) in the local network. 3. All devices in the network system (including original devices) Do not set to automatically obtain IP addresses. In the address mode, all IP addresses are set manually and registration is made. 4. If there are wireless routers in the network system, please note whether the IP address of the mobile phone and tablet in the wireless network system is in conflict. 5. The front-end switch is a single station. The number of connected IPCs can be less than 4 and 8-port 100M switches can be used. If more than 4 ports, please use 8-port full-gigabit switches. However, the number of front-end switches connecting to IPC should not exceed 6 because the front-end switch to the main room Only one cable is used for transmission. If the number of IPCs on the load is too high, packet loss, frame drop, delay, and stall occur. 6. The IPC connects to the front-end switch. Use the national standard super five cable, and the front-end switch to the main room of the machine room must use the national standard six types of network cable and six types of crystal head 7, the network dome, the network camera to the computer room main switch can only use the network switch relay Once, if the distance is too long can be used fiber optic 8, network dome, network camera to the front-end switch, such as the use of international super five shielded network cable length is best not more than 70 meters, such as the use of international six types of network is best not to More than 100 meters 9. When using fiber optic transmission, please use the 2-, 4-, and 8-port fiber switches in the company's quotation. The traditional way is that IPC is first connected to a switch with a network cable, and the switch is connected to the fiber transceiver. In this way, the signal is relayed once, and once the signal is relayed once, it will be lost. The use of fiber switches is IPC direct connection without relay, more stable and more reliable 10, the main room of the main switch, please do not choose to manage the switch, unless there is a relatively familiar with the set of management switches engineer, or system Larger 11. The main switchboard in the equipment room must be a full-gigabit switch with a large brand name. It must not be fully loaded. For example, if a 24-port Gigabit switch is actually used, you should not use more than 16 ports, because the data volume of the network HD monitoring is relatively large. And it is constantly transmitting data. The processing requirements for the switch are relatively high. If there is a phenomenon of delay or staging when a switch has many points, you can try to solve the problem by adding a switch.
