Line scan CMOS USB3 cameras

NECTA cameras provide unrivaled scan speed and quick system integration.
Ultra-fast acquisition rate, 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 eliminating the need for external power adapters. USB 3.0 provides the most cost effective and widespread interface, pushing speed performances at the top.

Powerful on-board image processing

NECTA provides powerful on-board user-controlled image processing: AOI, independent LUTs, FPN (DSNU & 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 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 direct encoder interface.

Driver and Software

An easy-to-use set of software API is available, which allows developers to quickly produce fast and well readable code on Windows (VC++/C#/VB.Net) and Linux (C++). Our Software Development Kit provided with NECTA cameras, is fully compatible with Cognex VisionPro, MVTech Halcon and other major machine vision software for industrial application.
