How to use

Install the recorder in a stable, ventilated location and connect cameras according to their interface types: coaxial for analog formats or network cabling for IP cameras. Connect the Gigabit Ethernet port to your network switch or router for remote access and configure network settings (DHCP or static IP) through the device web interface or client software. Install a compatible 3.5" SATA hard drive up to 16 TB for local recording, then initialize and format the disk via the recorder menus. Use the USB 3.2 or USB 2.0 port to export footage or connect a mouse for local control. Configure recording schedules, motion detection, AI event rules and user accounts according to your surveillance needs.

Usage recommendations

For reliable operation, use a quality, low-vibration 3.5" SATA HDD rated for surveillance workloads and ensure the recorder is placed in a dust-free, ventilated environment. Keep firmware up to date and restrict remote access with strong passwords and appropriate network firewall rules. When using mixed analog and IP cameras, verify per-channel settings and bandwidth allocation to avoid exceeding the 128 Mbps incoming limit for IP channels.
