Common questions
Does the DHI-NVR4104-4KS2 have PoE ports?
No. This is the non-PoE model, with one independent 100 Mbps Ethernet port, so the cameras need a PoE switch or their own power supplies. For 4 built-in PoE ports see the DHI-NVR4104-P-4KS2.

How much storage can I fit?
1 SATA III port, up to 10 TB for a single HDD. Dahua notes that the maximum HDD capacity varies with environment temperature. Choose a hard drive from the Hard Drive option on this page, or choose recorder only.
Which monitor outputs does it have?
1 HDMI output (up to 3840 × 2160, 4K) and 1 VGA output (up to 1920 × 1080).
Can it record cameras from other brands?
Dahua lists third-party camera access for Panasonic, Sony, Samsung, Axis, Pelco, Arecont, Canon and ONVIF, and interoperability through ONVIF (profile T, S and G), CGI and SDK.
