Rackmount video recorders in this category support capacities from 16 to 32 channels, with some systems also listing support for up to 24 4K cameras. Storage options range from single- or dual-drive configurations to chassis with seven or eight drive bays and capacities from 3TB to 48TB, while specified recording throughput ranges from 70 Mbps to 360 Mbps.

Rackmount video recorders in this category typically occupy one or two rack units, known as 1U or 2U, and many include rack-mount hardware. Power needs vary by model, while network connections may include built-in Power over Ethernet (PoE) camera ports, dedicated RJ45 ports, dual Ethernet interfaces, or an SFP+ uplink.

Built-in Power over Ethernet (PoE) ports can simplify rackmount video recorder installation by connecting compatible cameras directly to the recorder for both network communication and power, which can reduce separate cabling and hardware. Port counts vary, so confirm the recorder’s available PoE ports and channel capacity, and use a network switch when the system requires additional camera connections.

Plan storage around the number of cameras, recording resolution, retention period, and recording throughput, then select a rackmount video recorder with suitable hard drive capacity, multiple drive bays, or RAID storage for added data protection. For expansion, consider available HDD bays, recording channels, built-in Power over Ethernet ports, network connectivity for cameras added through a switch, and dual network interfaces where supported.
