Frequently Asked Questions

How should I choose between SYNL50 and SYNL50X?

Both models feature a 1/1.8-inch CMOS sensor, 1920×1080 resolution, and a 50mm/F0.9 lens, supporting three imaging modes: full-color, black-and-white, and low-light. Based on the available information, their core imaging specifications are similar, with no specific differences in imaging performance explicitly listed for the X‑series model. Both models operate at a supply voltage of DC 2.6–5.5V. Before making a purchase, please verify the power requirements, interfaces, and actual configuration with Soske Technology.

What is the difference between low-light night vision and thermal imaging?

SYNL captures images by detecting faint light with a CMOS sensor and allows users to switch between full-color, black-and-white, and low-light modes. Thermal imaging primarily reveals differences in the thermal radiation emitted by objects; the two technologies operate on fundamentally different principles. The performance of low-light observation depends on ambient illumination, the target’s characteristics, and auxiliary lighting conditions, and the sensor’s spectral band should not be equated with the presence of a corresponding illuminator.

What’s the difference between digital zoom and picture-in-picture?

Both models support continuous electronic magnification from 1× to 8×. Standard zoom enlarges the entire image, while picture-in-picture displays a magnified view centered on the dividing line, preserving the overall field of view. Electronic magnification is not equivalent to optical zoom and does not guarantee lossless image quality.

Does it support Wi‑Fi connectivity, photo and video recording, and local playback?

Supports Wi‑Fi and hotspot; you can view and livestream via a mobile app on smartphones, tablets, laptops, and other devices, with one‑tap photo capture, video recording, and local playback. It uses a TF card for storage, comes standard with 64 GB (optional 256 GB), features a USB Type‑C 2.0 data interface, and outputs video via HDMI at 1920×1080. Please consult for specific app details and compatible devices.

Can it be used in rainy weather and low-temperature environments?

The device features an IP66 waterproof and dustproof rating, operates in ambient temperatures ranging from −40°C to +60°C, and functions at relative humidity below 90% (non‑condensing). It also withstands shock loads of up to 1000G. Note that IP66 does not imply submersion; please follow the official user manual. Low illumination, rain, fog, or obstructions may still affect image quality.

What is the device’s power consumption and battery life?

Typical power consumption does not exceed 2.3 W, and continuous operation lasts more than 5 hours; actual battery life varies with environmental temperature, wireless connectivity, video recording, and other usage conditions. It uses a 16340 rechargeable lithium‑ion battery with a voltage of 3.7 V and a capacity of 1800 mAh.

What’s the difference between range measurement, detection/identification range, and one‑button gun calibration?

Laser rangefinding is used to provide target distance information, with a maximum range of 1,200 m and an accuracy of ±1 m; the pulse wavelength is 905 nm. The values listed in the specification sheet—detection at 2,600 m and identification at 650 m—are nominal imaging distances for a fawn (1.25 m × 0.5 m) and should not be interchanged with the rangefinding performance metrics. One‑button boresighting employs an AI‑based laser‑recognition algorithm to adjust the reticle to the designated position.
