PoE cameras are the best solution for gait analysis (walk or run). Unlike camcorders they offer 50 frames per second in full resolution (typically 1280 x 1024 or 2048×1024 pixels), enabling you to zoom right in to see discrete detail. They are ultra mobile and notebook friendly even over very long distances with the power being supplied via the Ethernet cable. High speed recordings at 100 fps for faster movements (2028×480 pixels) are also available. (High Speed Module required).

The Gigabit-Ethernet (GigE) cameras are connected via standard Cat 6 network cable to the computer and are capable of capturing 10 to 400 frames/s (dependent on model and resolution). The cables can reach a length of up to 100 m. All camera settings can be defined in the software.

Bullet cams provide superior images to webcams but don’t match the quality of an HD Camcorder. Unfortunately no zoom lenses are available nor do they allow easy focusing – but there are varying lenses to suit your needs. Bullet cams have automatic shutter speeds of up to 1/10000 of a second – the more light the faster the shutter – and the cable length can be extended up to 50 meters.

You can use webcams, however, they only produce 30 frames per second and the quality is poor, even with the latest cameras. You can’t adjust the shutter speed so you will see a lot of blur within those 30 frames.
