Why Buffered Cameras?
On-board memory used to temporarily store captured images.
Key advantages  Multi-camera applications
 Short & repeatable external trigger delay
 Arbitrary ROI’s (with Nx and Ny multiples of 4)

Global Shutter
• Pixels are exposed roll by roll
• All pixels are exposed simultaneously
• Usually has higher pixel count
• Good for moving objects
• Good for stationary or slow-moving
• No image distortion
objects
• May distort image for moving objects

Cameras with Built-in LED Drivers for Illumination
• Camera and LED drivers share the same PCB
• Ideal for camera applications requiring LED illumination
• 4 channels (e.g. R, G, B, and white)
• No external power supply needed
• 1W available for LED illumination
• Controlled through the same USB and the same GUIbased software
• SDK includes both camera and LED driver functions

Window-less USB2.0 CMOS Cameras
Why Window-less?
• Better sensitivity @ IR, VIS and UV
• Optics or other components can get closer to
the sensor
• No unwanted optical interference due to
multiple reflection
 Mission-critical applications

Key Selling Points of Industrial Cameras
• Highly reliable and widely tested SDK
• Excellent synchronization capability (i.e. short and highly-repeatable
external trigger delay)
• Support multi-camera applications
• DirectShow, TWAIN and Linux compatibility
• USB protocol for non-Windows systems
• Easy for system integration (e.g. with GPIOs, trigger in/out, etc.)
