Innovative Video Solutions - Why not make every room a sleep lab?


Wireless Sensor Enabled

Powerful Customizable Reporting.

Need simplicity? Then start with our standard report template and change the order if required. Or select the data you want in each table/graph and display it in the order you want. You can even add your own branding in the header.

Need more? Then use our custom report builder and make you own design with total freedom. The possibilities are nearly endless.

The future of PSG is here.

The future is here – our most powerful and flexible sleep diagnostic system. The SOMNOscreen® HD is a new generation of PSG with 55 channels (10 internal, 28 external, 17 EXG via the headbox) which can be upgraded to 70 channels, they are recorded at a resolution of up to 4 kHz per channel. 

With intelligent connect, the new montage free sensor recognition, you can connect any sensor to any slot and also change it during the measurement. If an installation on the PC has been selected before the cable is connected, the device will indicate any missing sensors. 

Thanks to the integrated data transmitter, the SOMNOscreen® HD allows additional  remote signal control of the measured data: You get a screenshot of the measured data on your tablet or computer. This way, you always know whether a patient’s home measurement is working properly, giving you peace of mind. In addition, the measurement is saved on the memory card of the SOMNOscreen® HD – no data is lost!

Adding video to this powerful device gives you new opportunities to offer the future of HST.

Unique Wireless Sensor Technology

The SOMNO HD™ is capable of accepting up to 6 wireless sensors – the first of these to be made available is the wireless PLM sensor package. More will follow in the future.

Why use a Wireless Sensor?

  • Time saving during application
  • More freedom of movement for the patients
  • Reduction of consumables and running costs (cables and connectors)

Details of the optional wireless PLM Sensors

  • Guaranteed measurement time of 10 hours
  • Outstanding signal quality
  • Continuous recording of the electrode impedance
  • Sampling rate adjustable between 64-512 Hz
  • Synchrony ≤ 60 ms
  • Automatic activation and start of the measurement by applying the sensor to legs and/or arms
  • Easy application with disposable electrodes (Ag/AgCl)
  • No additional costs due to environmentally friendly and rechargeable Li-Ion batteries
Docking station for simplified handling

The docking station is used to download the measurement data, charge the SOMNO HD™ Li-Ion battery and to install regular, free of charge firmware updates as long as you are connected to the internet. This means your SOMNO HD™ can be always up to date.

A virtual docking station also appears on your PC and shows the actual status of the device and the battery.

Of course, the SOMNO HD™, like the other SOMNOmedics devices, also offers real-time telemetric data transfer to the PC or tablet PC. In addition, the measurement data is saved on an internal memory and can be transferred at the end of the night via the docking station. So no measurement is lost.

Optional Video

The Mobile camera includes:

  • Tripod, case
  • Power supply
  • Built in Infrared-illumination
  • Video resolution of 800 x 600 pixel, in the H.264 format
  • Audio
  • Record up to 90 hours of video.
  • It’s small in size (137 x 124 x 71 mm) and light at only 460 g.
  • The accuracy of the synchronization between recorded data and video is ± 1 second

In the software the following can be achieved:

  • Synchronous play to physiological data.
  • Selectable speed (stepwise between 0.25 and 100x) with loop option.
  • 150 MB/h video size

Home Sleep Test Video Workflow

  1. Initialise a recording with SOMNOscreen® HD and the Home Sleep Camera.
    Both devices need to be connected to the same PC: The SOMNOscreen HD via its docking station, and the Home Sleep Camera via LAN cable.
  2. Give SOMNOscreen® HD and Home Sleep Camera to the patient.
  3. Patient set up camera at home in the evening: Assembles the tripod, connects to a power supply. The video recording will start automatically
  4. Patient packs up the video and tripod and gives the whole package back to the physician
  5. Transfer recording including video. Both devices need to be connected to the same PC: The SOMNOscreen HD via its docking station, and the Home Sleep Camera via LAN cable.

Optional Online signal check on a tablet or PC

Transfers the measured data to your tablet, PC or smart phone for instant signal check – right at the patients bedside or mobile as a screenshot. Transfer times and periods can be programmed individually.
