Cloud-based management
Devices can be managed via the DoLynk Care mobile application, which enables real-time network monitoring. The application displays device status, transmits real-time error notifications, and sends alerts to the user when problems occur.

Network Topology Management

The switch supports the LLDP protocol, which automatically creates a network topology. This provides a quick overview of connected devices and allows for remote troubleshooting of technical issues.

BT 90W (Red port)

The red PoE ports support IEEE802.3af, IEEE802.3at, IEEE802.3bt and Hi-PoE standards, providing up to 90 W output power per port. Suitable for devices requiring higher power (e.g., PTZ cameras or other high-consumption devices).

PoE Watchdog

The switch uses a smart PoE Watchdog function.
The function can be enabled either from the switch or via web management.
PoE Watchdog automatically detects when a port connected to a camera is not functioning correctly and restarts the port to restore the connection.
