Q: Which industries can EVO II Dual 640T be used in?
The EVO II Dual 640T was specifically built to serve industries and applications in public safety, inspection, search & rescue, fire response, and law enforcement.
Q: Is the EVO II Dual 640T waterproof?
No.
Q: What is the maximum flight time of the EVO II Dual?
In a steady environment, the max flight time can reach up to 38 minutes.
Q: What is the maximum wind resistance of the EVO II Dual 640T?
39mph.(17m/s).
Q: Does the remote controller support HDMI output?
No.
Q: How long does it take to charge the remote controller?
2 hours.
Q: How many ports does the remote controller have?
There is a Micro USB port and a Type-A port at the bottom of the remote controller which can be used for connecting external devices and charging.
Q: What is the effective image transmission distance?
Under the FCC standard, the maximum image transmission distance is 9km; under the CE standard, the maximum image transmission distance is 5 km.
Q: What should I do if the image transmission signal becomes weak
during flight?
Check your surroundings for potential interference factors and then adjust the orientation of your antennas to enhance signal strength.
Q: Can I change the gimbal mount?
Yes.
Q: What camera sensor does the EVO II Dual 640T use?
Visible light camera: 1/2-inch CMOS image sensor, 48M effective pixels, supporting 8K video recordinng. Thermal imaging camera: vanadium oxide uncooled infrared focal plane detector with a resolution of 640×512.
Q: What is the zoom range of the camera?
1-8x zoom.
Q: What is the temperature measurement accuracy of the
thermal imaging camera?
±3℃ or ±3% of reading (whichever is greater) @ambient temperature -20℃~60℃.
Q: What is the temperature measurement distance of the
thermal imaging camera?
2-20 meters.
Q: How long does it take to fully charge the battery?
It takes approximately 90 minutes to fully charge each battery.
Q: How does one maintain the battery?
1. Do not expose the battery to temperatures
below -10°C or above 40°C, which will shorten
the battery life and may cause fire, explosion or
other permanent damage;
2. Do not charge
immediately after flight; it is recommended to
charge the battery after it has dropped to room temperature;
3. The ideal charging environment temperature of the
battery is 10 °C~30 °C;
4. The ideal storage environment
temperature of the battery is 22 °C~28 °C. When storing,
it should be waterproof and moisture-proof, and avoid sunlight;
5. Recharge and discharge the battery every 3 months or
so to keep the battery active.
Q: Can the battery be used in a low
temperature environment?
Using the battery in a low temperature environment may reduce the battery life. For optimal performance, it is recommended to keep the battery temperature above 15 °C before flying.
Q: Can the battery be carried on board?
A single battery contains 82Wh. According to airline requirements, the battery can be carried on board.
Q: Can the batteries of the 640T and EVO II series be universal?
Yes.
Q: Does it support temperature post-processing?
Yes, we provide free temperature analysis tool IR PC TOOL.
Q: When to use FFC flat field calibration?
When noise appears on the screen, select FFC calibration to optimize image quality.
Q: What factors affect the accuracy of temperature measurement?
A. Influence of the atmosphere: the higher the temperature and humidity
of the atmosphere, the greater the temperature measurement error.
B. The distance between the camera and the measured object:
the farther the distance, the greater the temperature measurement error.
C. The emissivity and background temperature of the object:
When the surface emissivity of the measured object is low and the
background temperature is high, it will cause a large
temperature measurement error.
Q: In what mode can the temperature alarm function be used?
Regional temperature measurement.
Q: Does the aircraft support 2D and 3D modeling?
Yes, although this aircraft model is not specifically designed for surveying and mapping, it is functionally supported.
Q: After downloading the firmware package, can I disconnect the network
to upgrade?
Yes.
Q: How to upgrade the firmware?
You can download the firmware package manually through the official website, or update the firmware through the Autel Explorer application.
Q: After downloading the firmware package, can I disconnect the network
to upgrade?
Yes.
Q: What are the factors that can cause the upgrade to fail?
A. If the device is turned off during the
upgrade process, the upgrade will fail.
B. If the network is interrupted while
downloading the firmware package, the upgrade will fail.
C. Only when the remaining battery power of the device
is ≥ 50% can the upgrade be performed.
