Pay attention to the suitability of choosing ppe

Have you encountered these puzzles as well?

1: The network cable between the switch and the camera is abnormal. The camera cannot be monitored properly.

2: The cameras are very far apart. The construction غير مجاز مي باشدt and the wiring are messy.

3: The number of cameras is large. One port of the switch is connected to one camera. The construction غير مجاز مي باشدt and equipment غير مجاز مي باشدt rise sharply.

solution:

Using TG-NET Gigabit Access Switch S3500 series, use security monitoring downlink multi-ring technology. The following topology

Help you achieve:

1: Low-غير مجاز مي باشدt networking, less network equipment uغير مجاز مي باشدe, and less use of network transmission media;

2: No single point of failure, cameras in the ring network have backup links;

3: The layout is elegant, and the layout of the computer room network cable becomes relatively simple and regular;

Downstream multi-loop technical difficulties:

1: The access layer switch must support ring protocols such as STP, RSTP, and MSTP, and the convergence time of the protocol meets the network requirements.

2: Access switches must support VLAN and multicast functions;

3: The camera must support 2 network interfaces;

4: The camera supports ring network protocol at the same time.

(An advertisement for Dahua, my Dahua Camera perfectly supports this feature)
TG solution other advantages:

Centralized management:

Cloud-box, cloud-side, mobile-end-side maintenance network, network monitoring, network configuration, network alarm;

Monitoring priority:

Flexible application of QoS protocol to monitor data transmission priority;

Complete multicast:

Core switches MVR, IGMP Snooping, IP source protection, security monitoring network requirements for multicast applications;
