8-port Gigabit Ethernet switch extra digital TV990191, 8 × 10/100/1000 Mbps ports

The extra digital TV990191 is an 8-port Gigabit Ethernet switch that provides eight 10/100/1000 Mbps auto-sensing RJ45 ports with Auto MDI/MDIX. Designed for simple network environments such as homes, small offices, dormitories and small surveillance systems, the switch supports plug-and-play installation and can connect IP cameras, wireless access points and typical wired devices for reliable data and video transmission.

Advantages

This Gigabit switch operates in store-and-forward mode with a large-capacity buffer memory and full-port wire-speed forwarding to ensure stable 24/7 performance for video and data streams. Auto-detection of straight and crossover cables and auto-sensing ports remove the need for manual configuration. The device is compact, supports desktop or wall mounting and features low power consumption with a maximum total power draw under 6 W. CE, FCC and RoHS certifications are included.

How to use

Place the switch on a desktop or mount it on a wall using appropriate screws. Connect the external power adapter to an AC outlet and the switch's power input. Use Ethernet cables to connect devices to the RJ45 ports; the switch will automatically detect port speed and cable type (straight or crossover). For surveillance setups, connect IP cameras and a recording device or NVR to the ports for continuous video forwarding. No additional configuration is required for basic operation.

Usage recommendations

Install the switch in a ventilated, dust-free location within the specified temperature and humidity range. Use quality Cat5e or Cat6 cables for Gigabit links and ensure the power adapter is the supplied 5 V/1 A unit. For optimal video performance, connect cameras and NVR on separate ports and avoid daisy-chaining multiple unmanaged switches when possible.
