ITEM NAME:For IP Surveillance Projects Tenda TEF1109DT 9 Port 10/100Mbps Ethernet Switch Product Description Description: Tenda TEF1109DT 9 Port 10/100Mbps Ethernet Desktop Switch VLAN Button for Small Medium Sized HD IP Surveillance Projects Feature: 1. Port 1-8 are 100Mbps ports, and the 9th port is Gigabit uplink port. The first 8 ports are forwarded at 100Mbps line speed, and the uplink port still does not lose packets. In a monitoring project, a NVR is connected to the uplink port, and the downlink can be fully loaded with 8 0.5MP cameras; 2. Adopting a 1024kb large cache design, which is twice that of other brand switches in the same gear, and can be fully loaded with 8 500W cameras for video transmission, which is stable and does not freeze; 3. Due to the complexity of the monitoring environment, the access wiring and networking usually encounter the problem of insufficient network transmission distance. The distance between each camera terminal and the monitoring center is different, some only tens of meters, some hundreds of meters Even further. TEF1109D supports extension technology. When the extension mode is turned on, data transmission can reach up to 250 meters, which can replace extenders and some optical fibers, expand the scope of equipment, and save project costs; 4. Built-in professional protection circuit, supporting 6KV uplink port light ning protection. Effectively reduce the damage to the network system caused by thunderstorms and improve the robustness of the system; 5. Designed for small and medium-sized security monitoring. Ports 1-8 are isolated from each other, and port 9 is the uplink port. When the mode is turned on, it can isolate broadcast storms, prevent ARP viruses and DHCP spoofing, easily solve the problems of high-definition monitoring stuttering and unsmooth problems caused by broadcast storms, and improve the transmission rate and security of the intranet. Specification: Network standard: IEEE 802.3, IEEE 802.3u, IEEE 802.3x, I.TEF1109D supports extension technology. Ports 1-8 are isolated from each other, and port 9 is the uplink port. Built-in professional protection circuit, supporting 6KV uplink port light ning protection.
