What about customs?

We are not responsible for any custom fees once the items have shipped. By purchasing our products, you consent that one or more packages may be shipped to you and may get custom fees when they arrive to your country.

Do you provide tracking information?

Yes, you will receive an email once your order ships that contains your tracking information. If you haven’t received tracking info within 5 days, please contact us.

My tracking says “no information available at the moment”.

For some shipping companies, it takes 2-5 business days for the tracking information to update on the system. If your order was placed more than 5 business days ago and there is still no information on your tracking number, please contact us.

Will my items be sent in one package?

For logistical reasons, items in the same purchase will sometimes be sent in separate packages, even if you've specified combined shipping.

If you have any other questions, please contact us and we will do our best to help you out.

640×512 30Hz New Thermal Imaging Sensor
Equipped with 640*512 high-resolution thermal imaging camera featuring a 13mm focal length lens and 16x digital zoom, it is easy to observe distant targets. The system uses a new image processing algorithm, making thermal imaging details clearer and more discernible than competition with the similar resolution and hardware.

50MP Ultra-Sensitive Camera
The EVO II Dual 640T V3’s special RYYB sensor features a moonlight algorithm 2.0 that provides excellent noise suppression in limited lighting conditions, further enhancing its 50 megapixel camera to give users more details for better forensics and analysis.
8″ Sensor Size
8″ RYYB CMOS offers up to 144%~233% more surface area when compared to 1/2″ or 1/2.3″ competitors for maximum details in high contrast lighting conditions.
RYYB Sensor Technology
RYYB sensor technology moves away from RGB cameras by offering up to 40% more light sensitivity in low light scenarios.
PDAF+CDAF Autofocus System
Never lose sights of your subjects with a combination of PDAF (Phase Detection Auto Focus) and CDAF (Contrast Detection Auto Focus) technology for fast and accurate tracking.

See the Scene with 16x Digital Zoom
The system supports 16x digital zoom and 4x lossless zoom, providing long-distance image acquisition and detailed insight into scenes safely and without detection.

4K HDR for Greater Dynamic Range
4K HDR automatically balances overexposure and underexposure when shooting scenes with too much contrast, producing clearer images with more layers.
