Environmental testing and analytical services provide testing of environmental samples such as soil, water, air, and industrial wastes or byproducts.

Access control, security and biometrics equipment is used to monitor and restrict access to equipment, parts of buildings, or entire facilities

Broadcasting, studio and theatrical equipment, supplies and services includes video production consoles, theatrical lighting, theatrical curtains, and related products and services

Video cameras take continuous pictures and generate signals for display or recording. They capture images by breaking them down into a series of lines. This search form does not include consumer devices such as camcorders.

Specialized audio equipment is used in specific industries such as the recording industry, and for specialized applications such as voice digitizing and analysis

Digital video recorders record and store video camera output in digital form on disk.

Specialty or proprietary equipment and accessories related to laboratory sample preparation

Closed circuit TV (CCTV) is used for area surveillance and remote monitoring. Some systems can record events and trigger alarms

Charge coupled device (CCD) cameras contain light-sensitive silicon chips that detect electrons excited by incoming light. They also contain micro circuitry that transfers a detected signal along a row of discrete picture elements or pixels, scanning the image very rapidly. CCD cameras use two-dimensional CCD arrays with many thousand of pixels.

Towers, poles and support structures elevate, support and/or position personnel and equipment such as antennas, lighting, surveillance cameras or sensors, wind turbines, weather instruments, and power lines

Thermal imagers detect heat patterns in the infrared wavelength (1 micron to 100 micron) spectrum.

Video cassette recorders (VCRs) receive video input and capture data onto analog or digital videotape. Consumer-grade products are not included in this category.

Audio microphones are designed for sound reception and recording applications (speech and music).

Vision sensors are machine vision video cameras with integrated signal processing and imaging electronics. They typically include program and data interfaces.

High speed cameras are designed for rapid image acquisition for scientific or industrial analysis of rapidly changing or moving processes.
