Unmanaged Ethernet switch with 5*10/100M RJ45 ports. External power supply.



The DARWIN-S221NA050000 is an unmanaged 10/100M Ethernet security switch independently developed. It has 5*10/100Base-TX RJ45 ports. The scheme of the large backplane and large cache switching chip is preferred to improve the forwarding rate of large files and effectively solve the problems of video freeze and picture loss in the high-definition surveillance environment. It is suitable for hotels, banks, campuses, factory quarters and small and medium-sized enterprises to establish a cost-effective network.


Unmanaged mode, plug and play, no configuration, simple and convenient to use.






10/100M line speed transmission

◇ Support non-blocking wire-speed forwarding.

◇ Support full-duplex based on IEEE802.3x and half-duplex based on Backpressure.



Stable and reliable

◇ CE, FCC, RoHS.

◇ Low power consumption, no fan, flame retardant plastic casing.



Easy to operate

◇ Plug and play, no configuration, simple and convenient.

◇ The user-friendly panel can show the device status through the LED indicator of PWR, Link/Act.
