Line scan CMOS USB3 cameras

NECTA cameras provide unrivaled scan speed and quick system integration.
Ultra-fast acquisition rates, extremely reduced dimensions, and rugged design make NECTA cameras suitable for the most demanding applications requiring automated visual inspection, industrial metrology, high-performance sorting, spectrometry, and machine vision.

All our cameras are powered directly by the USB3 bus, with no need for external power adapters. USB 3.0 provides the most cost-effective and widespread interface, pushing speed performances to the top level.

Powerful on-board image processing

NECTA provides powerful onboard user-controlled image processing: AOI, independent LUTs, FPN (DSNU and PRNU), gamma correction, white balance, saturation, hue, and black level offset calibration.

Versatile I/O

NECTA provides a versatile I/O interface to control external devices such as strobe lights, encoders, etc., 2 input lines with a direct encoder interface, 2 output lines, and 1 input/output (RS422, RS644 LVDS, LVTTL). Its multipurpose I/O connector provides user I/O, line/frame triggering, and a direct encoder interface.

Driver and Software

NECTA is GenICam GenTL compliant and comes with a comprehensive SDK for Windows and Linux, supporting all major programming languages such as Python, C#, VB, and C++ in the Visual Studio or QT environments.
Our Software Development Kit, provided with NECTA cameras, is fully compatible with Cognex VisionPro, MVTech Halcon, NI LabView, and other major machine vision software for industrial applications. It can also be used with embedded computing platforms such as Jetson Nano, Jetson Orin, and Raspberry.
