Versatile Mini DVR Recorder

The GRACETOP GTUS-SDIDVR captures video from SDI, TVI, HDMI or DVI sources in a compact box. It handles 3G-SDI and HD-SDI signals alongside 4K30 HDMI input for professional recording workflows. An SDI loop-through output allows the source signal to continue to other equipment while recording.

DC Power Range and Silent Operation

The unit accepts a wide DC input from 7 to 20 volts for flexible power integration. With no moving parts listed, it runs silently during capture sessions. Power draw scales with the connected storage and active encoding load.

USB Storage and IR Control

A single USB port connects flash drives or portable hard drives up to 1TB for MP4 recording. Two LED indicators show power and recording status at a glance. The included infrared remote lets you trigger manual, boot-up or timed recording without touching the device.

Questions about this item

How do I connect the GRACETOP GTUS-SDIDVR to power and avoid the common mistake of using the wrong voltage?

Connect a DC power source between 7 and 20 volts to the DC input. The step people get wrong is applying voltage outside this range, which can prevent the recorder from starting or cause unstable operation.

What storage maintenance will the GRACETOP GTUS-SDIDVR need after extended recording sessions?

The recorder stores MP4 files on a USB-connected U disk or mobile hard drive up to 1 TB. Maintenance consists of periodically offloading footage to free space and checking the drive's health, as the unit has no internal storage to manage.

Which recording limit appears first when capturing 4K30 H.265 video continuously on the GRACETOP GTUS-SDIDVR?

The 1 TB USB storage ceiling is reached first; at typical 4K30 H.265 bit-rates the drive fills in roughly 8 to 10 hours, while the DC 7-20 V power input and H.264/H.265 engine impose no shorter time limit.
