Note that many webcams will run slower if there is low lighting, so for example, it might be 30 FPS when pointed at a bright light but only 10 FPS when pointed at a shadow. Typically, webcams are successfully giving the same frame-rates & resolutions on Jetson TK1 as on an x86 desktop running Linux (eg: 640x480 30 FPS, 960x720 15 FPS, and 1920x1080 15 FPS). Logitech C910 is known to work on Jetson TK1 in uncompressed modes but has not been tested in 1080p compressed mode. However, USB 2.0 is the slowest of the possible camera interfaces, so it usually only supports upto 720p 30fps (eg: Logitech C310 $45 (untested)), (except for the few USB 2.0 cameras supporting 1080p video compression, such as Logitech C910 (untested)). USB 2.0 (480 Mbps) is the most common & cheapest method for camera input, since USB 2.0 webcams range from $5 - $200. Many of these cameras can be accessed by following the Camera access section, also further bellow. It is also possible to use Multiple cameras, Stereo cameras, or Specialized camera sensors as discussed further below.
Analog video capture cards, available through mini-PCIe (eg: mini-PCIe (untested)), USB 3.0 (eg: USB 3.0 (untested)), or USB 2.0 (eg: USB 2.0 (untested)). Firewire (available through mini-PCIe), eg: mini-PCIe (untested). MIPI CSI-2 camera ports (up to 12 lanes at 2.5Gbps each). Additional Gigabit or Dual-Gigabit Ethernet ports can be added through mini-PCIE, eg: mini-PCIe (untested). USB 2.0 port (through a micro-B to female USB-A adapter, that is sometimes included with Jetson). Additional USB 3.0 ports can be added through mini-PCIe, eg: mini-PCIe (untested). USB 3.0 port (supports many USB 2.0 or USB 3.0 webcams). The Jetson boards provide several different interfaces that allow camera input: 5.2 Asus XTion Pro Live RGB-D Sensor using OpenNI2 library. 5.1 Microsoft Kinect Structured-Light 3D Depth camera. 2.5.2 Building your own custom MIPI CSI-2 camera module. 2.5.1 MIPI CSI-2 sensors known to be working. 2.3.1 Gigabit network cameras known to be working. 2.2.2 USB 3.0 webcams known to be working. 2.2.1 Enabling support for USB 3.0 on the full-sized USB port. 2.1.3 USB 2.0 webcams with known problems. 2.1.2 USB 2.0 webcams known to be working.
