Do you know how to record 2500 mbytes/second of video for 6 hours?

In this case, NorPix provided a recording solution that allowed the client to record 2 cameras with a resolution of 9 megapixels at a rate of 290 frames per second or 2,500 Mbytes/second for a duration over 6 hours.

Underwater High-speed Web Streaming and multi-camera recording

NorPix has developed a system for a military client providing underwater high-speed web streaming HD capture at 338 frames per second from 18 cameras simultaneously along with live streaming to a remote recording station.

Underwater High-speed Web Streaming
The solution uses StreamPix Remote to manage 18 Emergent HS-2000 cameras in waterproof enclosures. The setup uses 5 PCs for uncompressed recording from up to 4 cameras each, 2 PCs for compressed recording, and one PC for remote control and real-time display. All camera-to-host connections are by 30- to 150-meter fiber optic cables, each on a 10GigE network.

Details of the system include:

  • Each of the front line computers records a total of 2.6 GB data/second from four HD 1920×1080, 338 fps cameras in uncompressed RAW8 format.
  • Every 24th frame (1 in 14) is decimated to half resolution (960 x 540) and real-time H.264 compressed so that a live stream is delivered to 2 secondary remote recording stations at about 50 megabits/second. The H.264 compression is GPU accelerated.
  • The remote PC controls recording and playback, as well as gain, exposure, and white balance for each camera. It also allows control of focus and iris.
  • Dual large monitors provide a tiled display of all cameras plus a large display of a selected camera directly on the 2 secondary recording stations.

Airborne high resolution capture application using a portable PC

airborne-high-resolution-capture-application-acme-megapacl1-norpix-2

The MegaPAC L1 product is a robust portable computer built using all aluminum sheet metal to provide tough, go-anywhere unit suitable for tough environments and mobile applications.

This airborne capture system uses a portable computer with multiple drives for capturing high resolution images at low frame rate all day long. In this instance, the camera to be used will be a 29MP camera link camera in 12 bit mode. Frame rate on the camera is 5 fps for a total data rate of 290 MB/second. Over an 8 hour day this represents over 8 Terabytes.

Customer constraints were based on capturing in Raid10 for data redundancy.

Norpix has proposed using Streampix with the GPS module and a portable computer from ACME. The Streampix software can easily capture video data from the camera with GPS tagging and time stamping to disk in uncompressed format. Norpix proposed to our reseller the use of the ACME computer which allows the use of normal high capacity hard disk drives in a portable format.

 

airborne-high-resolution-capture-application-acme-megapacl1-norpix-

With its functional design and rugged construction, the MegaPAC L1 is the most durable and versatile portable platform for your applications.

  • Each drive is over 4 Terrabytes
  • ACME computer can fit 7 drives
  • Total capture capacity is 28 Terrabytes
  • Raid setup is Raid5 to provide some data protection, but Raid 10 can also be used by reducing capacity
  • ACME provides hot swap capabilities permitting the customer to easily change disks
  • Power source between 12 and 28 Volts DC for helicopter use.

Multi camera capture in the fight against malaria

This is a system developed by NorPix® for Prof. David Towers from Warwick University, formerly from the Liverpool School of Tropical Medicine. The multi camera capture system is being used in the field in Tanzania where Prof. Towers is investigating optical techniques and quantitative data analysis to understand mosquito behavior in sub-Saharan dwellings in order to design more effective controls of malaria transmission. The system is powered off of a Honda generator on the edge of a swamp (mosquito breeding area).

Picture here shows where the computers are kept so that Prof Towers can conduct his research on mosquitos. On the right, you can see the experimental hut with the capture cameras.

This research team has submitted a publication to Nature Scientific Reports with follow up papers in the Royal Society Interface and in the Malaria Journal.

Infrared tracking of multiple mosquitoes attempting to reach a human volunteer.

Infrared tracking of multiple mosquitoes attempting to reach a human volunteer.

The system used in this research has 2 Baumer cameras at a resolution of 4MP each. The researchers are looking at adding 2 more cameras. This would allow the research to expand to other parts of Africa where there are insecticide resistant mosquito populations. A third project would require the use of 8 Baumer 4MP cameras, all capturing moving mosquitos in sync.

StreamPix 6 multiple camera is used to capture images from two cameras at 4MP each. The StreamPix motion detection module is used to monitor fly activity.  The module monitors activity at 10 images per second and triggers a capture at 100 fps from each camera once motion is detected for a specific length of time.  The length of sequence capture is adjustable by the user

In the past two years, the introduction of high speed and high resolution CoaXPress cameras has generated a considerable increase in data rates. NorPix has kept pace with this emerging technology to record from these cameras direct to disk without compression or image degradation. Read more

Video Scope module for 8 and 35mm film digitizing

When digitizing film stock, color rendering can shift over time, resulting in less realistic output requiring further color correction downstream.

The StreamPix 6 Video Scopes module can dramatically improve workflow for film digitizing by providing real-time feedback on the color space during the conversion process, reducing the need for further color correction later. The Video Scopes module includes a Waveform Monitor, Vector scope, Histogram and YUV/RGB parade. Read more

Small form factor recorder from Neousys

Small form factor recorder from Neousys

Small form factor recorders have the advantage of small size, useful for outdoor usage or when there is constraint in space. Unfortunately, they also have some limitations for long duration high speed video recording, as they come with limited expansion slots and fewer interfaces for media storage.

A number of companies make PC based small form factor units compatible with our StreamPix, TroublePix and Hermes API software products. Neousys, a Taiwanese company, makes 2 interesting fanless units that can accommodate an Intel core i7 CPU: the Nuvo 4000 and the Nuvo-3616VR.

The Nuvo 4000 has 2 PCI Express expansion slots that are compatible with frame grabbers. The unit comes with 4x USB 3.0 and 2x GigE ports pre-installed for use with USB 3 Vision and GigE Vision cameras. The limiting factor on this unit is that only 2 hard disks can be installed.

The Nuvo-3616VR unit provides no internal PCI Express expansion slot, but on the other hand, comes with 2x USB 3.0 and 16 GigE ports. All are compatible with USB 3.0 Vision and GigE Vision cameras that are supported by our software products. Furthermore, this unit accommodates 4 disk slots, two internal and two removable. This is one of the most flexible units for long term recording using USB 3.0 Vision or GigE Vision cameras.

 

Motion analysis high-speed video capture for biomechanical applications

When capturing for motion analysis or the biomechanics of animals such as bats, primates, or lizards, it is essential that their movements be captured at high speed. With StreamPix® software, either a single camera or multiple synced cameras can be used to take rapid, uncompressed video.

In this example, a portable setup is shown for capturing lizard movements in an outdoor environment. Read more
