The ace series of cameras offer fantastic value. This model is built on the Sony Pregius IMX265 1/1.8" sensor. It offers 3.2 MP (2048 x 1536) resolution with astounding image quality: high quantum efficiency, wide dynamic range, and extremely low noise.

When this camera is configured to use the sensor's full resolution, it can deliver 35 frames/second ("fps"). However, when configured to use less resolution, the frame rate will increase. As examples, 2048 x 1536 delivers 35 fps, 2048 x 820 delivers 67 fps, and 2048 x 480 delivers 111 fps. (Note maximum frame rate also depends on the output format, exposure time, and your network hardware.)

Using a Power over Ethernet (“PoE”) configuration, a single cable may be used to apply camera power and to transfer data between this camera and a PC, keeping cable runs to a minimum. An auxiliary connector is provided for terminating the optically isolated input and output signals – there is one of each. The input may be configured to trigger image acquisition, reset the frame counter, or reset the software trigger count. The output may be configured to indicate acquisition trigger wait, exposure active, flash window, or timer active. Or the output may be controlled via a PC. This camera also has one TTL line that may be configured either as an input or an output. The auxiliary connector may be used to power the camera if PoE is not available.

The Basler ace provides a full set of features to address a wide range of applications. Pixel data can be output in 8 or 12 bit depth. You may adjust the camera’s black level, gain, area of interest, input debounce, and trigger delay. It features automatic exposure control, pixel binning, horizontal image mirroring, event reporting, sending of test images, and a programmable lookup table. There are also “chunk” features that include a frame counter, time stamp, trigger input counter, and CRC checksum calculator. Note that not all features may be available when using third-party software.

This camera features Basler PGI in-camera image optimization, including 5x5 debayering and color anti-aliasing for improved sharpness and reduced noise.

This camera has a global shutter for “stop-action” imaging. The camera can output a flash window signal to control the light source.

Because this camera is GigE Vision and GenICam complaint, there are many third party software applications and API’s that are compatible. Basler offers their royalty-free Pylon SDK for 32 and 64 bit Windows, Linux and OS X platforms.
