Dahua XVRs are Penta-brid recorders: one unit that accepts five signal types — HDCVI, older analogue (CVBS), AHD, TVI and IP — at the same time. That makes an XVR the natural upgrade for an existing coax system: keep the cabling and coax cameras you have, add IP cameras on spare channels as you go. Many models below carry WizSense AI for human and vehicle detection. Every model links to its full specification.
