No.

In a steady environment, the max flight time can reach up to 38 minutes.

The EVO II Dual 640T was specifically built to serve industries and applications in public safety, inspection, search & rescue, fire response, and law enforcement.

Check your surroundings for potential interference factors and then adjust the orientation of your antennas to enhance signal strength.

Under the FCC standard, the maximum image transmission distance is 9km; under the CE standard, the maximum image transmission distance is 5 km.

Yes. There are two customizable buttons on the back of the remote controller, and 4 functions can be customized through the APP.

It uses a 3.26 inch OLED screen with a resolution of 854*480.

2 hours.

There is a Micro USB port and a Type-A port at the bottom of the remote controller for connecting external devices and charging.

No.

1. The influence of the atmosphere: The higher the temperature and humidity of the atmosphere, the greater the temperature measurement error.

2. The distance between the camera and the measured object: The farther the distance, the greater the temperature measurement error.

3. The emissivity and background temperature of the object: When the emissivity of the surface of the measured object is low and the background temperature is high, it will cause a large temperature measurement error.

Yes. We also provides a temperature analysis tool called the IR PC TOOL.

2-20 meters.

±3℃ or ±3% of reading (whichever is greater)
@ambient temperature -20℃~60℃.

1-8x zoom.

Yes.

The energy of a single battery is 82Wh. According to airline requirements, the battery can be carried on board.

When using the battery in a low temperature environment, the battery life may be reduced, please be sure to fly timeously. For optimal performance, it is recommended to keep the battery temperature above 15 °C before flying.

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 drops 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 the battery, the surroundings should be clear from water and moisture, and must avoid sunlight;

5. Recharge and discharge the battery every 3 months or so to keep the battery active.

It takes approximately 90 minutes to fully charge each battery.

Yes.

Yes, although this aircraft model is not specifically designed for surveying and mapping, it is functionally supported.

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.

Regional temperature measurement.

When noise appears on the screen, select FFC calibration to optimize image quality.

Yes, we provide free temperature analysis tool IR PC TOOL.

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 firmware be upgraded.

Yes.

You can download the firmware package manually through the official website, or update the firmware through the Autel Explorer application.

You can download it from the official website or contact an authorized dealers.
