• Acoustic imaging camera
• Cordless version (camera is not connected to battery via a wire)
• Locates pressurized leaks in compressed air systems
• Detects partial discharge from high-voltage electrical systems
• For users not needing both functionalities, please see Si124-LD Cordless (leak detection) and Si124-PD Cordless (partial discharge)

The FLIR Si124 is an intelligent, easy-to-use imaging system designed to visually show pressurized leaks in compressed air systems and display partial discharge problems in high-voltage electrical systems.

This lightweight, one-handed solution can help utility, manufacturing, and engineering professionals identify efficiency loss and potential failures up to 10 times faster than traditional methods. Built with 124 microphones and a frequency range that covers audible and ultrasound (2 kHz to 65 kHz), the Si124 filters out industrial background noise to produce precise acoustic imagery. The acoustic image is overlaid in real-time on top of a digital camera picture, which allows the user to accurately pinpoint the source of the sound and classify problems.

The Si124 features a plugin that enables users to import acoustic images to FLIR Thermal Studio suite for offline editing, analysis, and advanced report creation. Field analysis and reporting can also be done using the FLIR Acoustic Camera Viewer cloud service. Adopting the FLIR Si124 as part of a regular maintenance routine, professionals can identify issues fast—helping utilities keep the power flowing and manufacturing operations going.

The FLIR Si124 is available in several versions with different levels of functionality. The device can also either be powered cordlessly by a battery attached to the camera, or connected via wire to an external battery pack.
