The HVO-4000MT is a 4K, 3D and 2D medical grade video recorder that's intended to record 4K video and still images from endoscopic/laparoscopic camera systems, surgical microscope and other compatible imaging systems. 

Images captured with the HVO-4000MT can be used for patient records, training or educational purposes. The compact, portable recorder is suitable for use in hospital operating rooms, medical imaging centres, surgical centres, clinics, doctor's offices and similar healthcare environments. 

The HVO-4000MT offers a long time recording on its internal hard disk drive Recorded videos can be exported to an external USB hard drive, flash memory or CIFS server via hospital networks for storage, sharing with other consultants and teaching purposes. 

HVO-4000MT is designed to comply with medical safety standards and is optimised for medical applications. This equipment is intended for use by qualified medical professionals only. 

Compliance with Medical Safety Standards: 
  •  UL: UL60601-1+ANSI/AAMI ES60601-1, FCC: Part15 Class A Digital Device 
  •  cUL: CAN/CSA-C22.2 No.60601-1+No.601.1, IC: ICES-003 Class A 
  •  CE: EN60601-1+EN60601-1-2 
  •  CB: IEC60601-1, IEC60065, IEC 60950-1

  • 4K video recording
The HVO-4000MT records detail-packed 4K (3840 x 2160) video using Sony's XAVC S codec and efficient MPEG-4 AVC/H.264 compression for extremely high quality images with four times the resolution of Full HD. Recording bitrate is selectable to suit various requirements for picture quality and recording length.

  • Simultaneous recording in 4K and 2K (Full HD)
The same video footage is recorded simultaneously in 4K and 2K (Full HD). Down-converted from the captured 4K video, this 2K material is ideal for everyday sharing and playback on standard PCs.

  • Simultaneous recording on internal HDD and external media
Video files can be recorded simultaneously onto the internal hard disk drive and an external USB HDD, USB flash drive or network server. This shortens workflow, with no need to export or copy videos to an external device after recording on the internal HDD.

  • Long recording time
The recorder’s high-capacity 4TB disk drive allows long duration video recording, even in 4K. Three image quality settings (Standard/High/Best) permit between 46 and 119 hours of 4K video recording (or between 311 and 634 hours of Full HD video recording). Individual recordings can be up to 24 hours long.

  • Networked data transfers via CIFS
Recorded data can be uploaded over the hospital network from the operating room to a computer using CIFS (Common Internet File System) for convenient centralised storage and sharing.

  • 3.5" colour LCD
The front panel's 3.5" colour LCD screen allows current input image and status, playback images and recorder settings to be reviewed without the need for an external display.

  • Light, compact design
Designed for easy integration a medical cart, the space-saving recorder is 76mm slimmer and weighs 1.9 kg less than previous models (HVO-1000MD and HVO-3000MT).

  • Low power consumption
The recorder consumes approximately 65W less power than previous models (HVO-1000MD and HVO-3000MT).

  • Touch panel support
Adding an optional USB external touch panel monitor (commercially available) simplifies data input (for example, entering the patient’s ID, name, gender and date of birth).
