01 / THERMAL CLARITY
The details are clear,
Beginning with perception
Uncooled vanadium oxide detectors sense the target’s temperature distribution and contours. Available in two detector configurations—384×288 and 640×512—and paired with digital enhancement and image-processing algorithms, they make fine details easier to discern. The SYNCX series introduces three new ranging functions, with a range of 1,200 meters and an accuracy of ±1 meter, operating at a pulsed wavelength of 905 nm.

Frequently Asked Questions
How do you choose between SYNC25X, SYNC35X, and SYNC55X?
The three models are equipped with 25mm, 35mm, and 54mm F1.0 lenses, respectively. Their detection/identification ranges are: SYNC25X—1,300 m / 300 m; SYNC35X—1,800 m / 450 m; SYNC55X—2,800 m / 700 m—suitable for typical climatic conditions. All three models offer a ranging distance of 1,200 m. Weighing no more than 600 g, 720 g, and 720 g, respectively, including the battery, they can be selected based on lens type, field of view, and portability requirements.
Are there two detector configurations: 384 and 640?
Yes. The three models are available with two detector configurations—384×288 and 640×512—both featuring a 12 μm pixel pitch. The specification table lists the field of view for each model side by side, allowing you to compare the observable area; please consult us to confirm the exact configuration available for delivery.
What’s the difference between digital zoom and picture-in-picture?
All three models support continuous electronic magnification from 1× to 8×. Standard zoom magnifies the entire field of view, while picture-in-picture zoom displays a magnified close-up while preserving the overall scene. Electronic magnification is not optical zoom and does not guarantee lossless image quality.
Does it support Wi‑Fi connectivity, photo and video recording, and local playback?
Supported. All three models feature Wi‑Fi and a hotspot, enabling viewing and live streaming via a mobile app, as well as one‑tap photo capture, video recording, and local playback. Standard storage is 64 GB, with an optional 256 GB; for details on the app and compatible devices, please contact Soske Technology.
Can it be used in rainy weather and low-temperature environments?
The product is rated with an IP66 waterproof and dustproof seal (airtight), operates in ambient temperatures from −40°C to +60°C, and functions at relative humidity below 90% (without condensation). It also withstands an impact resistance of 1000G. IP66 does not imply submersion; please operate in accordance with the official user manual.
What is the device’s battery life?
All three models have a typical power consumption of ≤2.3 W. The SYNC35X and SYNC55X specifications state a continuous operating time of over 5 hours; the SYNC25X does not specify a continuous operating time. Actual battery life may vary depending on factors such as temperature, wireless connectivity, and video recording.
What is the difference between SYNCX’s ranging and its detection/identification range?
Ranging is used to provide target distance information; the three models are rated for a nominal range of 1,200 m with an accuracy of ±1 m, employing pulsed 905 nm wavelength. Detection and identification ranges describe thermal imaging capabilities and constitute a separate set of performance metrics that are not interchangeable. Actual performance is influenced by the target and environmental conditions; the specifications do not mention a dual‑field‑of‑view switching feature.
