A thermal camera detects infrared radiation emitted by objects and creates a temperature map of the scene. It is ideal for detecting hotspots caused by electrical faults, loose connections, overloaded conductors, and insulation failures.
An acoustic imaging camera uses an array of microphones to detect and visualize ultrasonic sound (typically 2–100kHz) emitted by partial discharge, compressed gas leaks, and mechanical vibrations. It creates a visual "sound map" overlaid on a camera image, showing exactly where the sound is coming from.
For comprehensive electrical inspection, both technologies are complementary: acoustic imaging detects the PD activity, while thermal imaging confirms the hotspot and assesses severity.
For most electrical inspection applications, a 384×288 resolution camera provides an excellent balance of performance and cost. For substation inspection at distances over 10m, or for high-precision thermography, consider 640×512 or higher.
The key rule is the "2-pixel rule": the target must occupy at least 2×2 pixels on the detector for accurate temperature measurement. Our Thermal Camera Buying Guide has a detailed resolution selection table.
NETD (Noise Equivalent Temperature Difference) is the smallest temperature difference the camera can detect. A lower NETD means better sensitivity. For electrical inspection, we recommend:
Our EasIR S-series achieves 15mK NETD — exceptional sensitivity for early fault detection.
Yes. All handheld thermal cameras and acoustic imaging cameras include Windows-compatible PC analysis software. Features include:
Yes. All our products are CE certified for the European market. Most products also carry FCC certification for the US market. We can provide certification documentation upon request. Products also comply with RoHS directives for hazardous substance restrictions.
Yes. The GSW Series is a dual-function instrument. It can detect:
The camera automatically classifies PD type (tip, suspension, surface, particle) and provides PRPD spectra for severity assessment. Detection range is up to 130m.

We ship to over 30 countries worldwide, including the US, Canada, UK, EU countries, Australia, Middle East, Southeast Asia, and South America. If you are unsure whether we ship to your country, please contact us and we will confirm.
Please note that some countries may have import restrictions on certain electronic equipment. We recommend checking your local import regulations before ordering.
All shipments are made on DAP (Delivered at Place) terms unless otherwise agreed. This means the buyer is responsible for import duties, taxes, and customs clearance in the destination country. We will provide all necessary documentation (commercial invoice, packing list, certificate of origin) to facilitate customs clearance.
The 12-month warranty covers defects in materials and workmanship under normal use conditions. This includes:
The warranty does not cover physical damage, water damage beyond the IP rating, or damage caused by improper use.
Technical support is available via:
We also provide user manuals, software downloads, and calibration certificates for all products.
Yes. We offer factory calibration services for all thermal cameras and partial discharge detectors. Calibration certificates traceable to national standards are available. Annual calibration is recommended for instruments used in critical applications. Contact us for calibration pricing and turnaround time.
