The Basler Ace 2 a2A4504-18umBAS GigE Vision camera offers great value. This is the "Basic" model. Despite the name, it offers all the capabilities many installations demand.

With USB3 Vision, a single cable is 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 input and output signals – there is a total of four.

The Basler ace 2 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.

Because this camera is USB3 Vision and GenICam compliant, there are many third party software applications and API’s that are compatible. Basler offers their royalty-free Pylon SDK with support for most operating systems.

The Basler ace 2 is available in "Basic" and "Pro" versions. Both versions feature a status LED on the back, a removable IR cut filter, and a robust M8 I/O connector. This is the Basic version.
