Zeroing steps.

1) Setting “Cursor X” and “Cursor Y” to (0,0) by APP “Setting” or

NVDevice button combinations: “ ”+“ ”, “ ”+“ ”,

“ ”+“ ”, “ ”+“ ”.

2) Install NVDevice on the gun, fix the gun on a stable platform.

3) Set a target 50 meters (the Metric system) or 50 yards (the British

system) far away.

4) Shoot a shot at the target.

5) Setting zero point "X" to bullet drop point by APP “Setting” or

NVDevice button combinations: “ ”+“ ”, “ ”+“ ”,

automatically. the other parameters is set Manually. 5 bullet

parameters is provided by the manufacturer, once the parameters

are modified, they will be automatically recorded, and do not need to

be re-entered later. Other parameters refer to Notes.

Exit ballistic menu, " " jumps to the corrected position after

ballistic calculation, shoot with " " aiming at target immediately.

Notice:

1) Bullet Caliber, Adopting international common British u nits. For

example, the .500 inch corresponds to the metric 12.7mm.

2) Bullet Weight, Adopting international common British units Grain.

3) Target Range, input according to the optical ranging results

described in section 4.1.

4) Target Angle, Which corresponds to the slope angle of the target,

is automatically measured by the gyroscope inside. Figure 2.9 is an

example of the target angle. If the target is higher than the

NVDevice ,the angle is >0, otherwise the angle is

5) Wind Velocity

Figure 2.11

The wind direction is shown in Figure 2.11. The wind velocity

calculation is based on experience.

Half speed wind, Wind Velocity = Actual wind speed/2, Wind

direction ∈ [-30,-60], [-120,-150], [30,60], [120,150] degree.

Full speed wind, Wind Velocity = Actual wind speed, Wind

direction ∈ [-60,-120], [60,120].

Downwind and headwind, Ignore.

The wind direction is clockwise from 0° to -180°, Wind Velocity 0. The actual wind

speed is judged by experience, such as leaf, tree, dust and other

reference materials moving with the wind. Downwind and headwinds

can be ignored in the effective range of civilian hunting rifles.

6) Relative Humidity, Judged by experience, and the datum is not

recorded.

Figure 3.2 is APP interface, icons functions are as follows:

, Local takes a photo.

, Local video recording, click it to record or stop.

, Unlock or lock cursor movement function. Unlock , input the

password (Figure 3.3), original password is "123456", you could

enter the setting panel to set a new password by clicking .

, If unlock, cursor move up / down / left / right,

used for calibrating guns.

, If unlocked, cursor move by finger within a certain range.

Under normal communication conditions, NVDevice records the

coordinates of the current cursor automatically when there is no

operation within 5 seconds.

, Switch to setting panel, options: Image View Grade, Hardware

Decoder, Quality Priority, CursorX/CursorY, Set time and Password.

In usual, you just need to click Set time icon to synchronous

NVDevice and mobile device, and set CursorX/CursorY to

calibrating guns. If you want to set more options, please go to

Appendix B for detail. Ballistic calculation refer to section 2.4.

4 Range Finder and Fast Aiming 4.1 Range Finder

Range estimation is quite important, we could estimate range by

optical probabilistic ranging according to reference object. Usually,

we chose prey animal as reference object, reference height of four

normal prey animals are listed as follow, such as bear, deer, boar

and pheasant.

Figure 4.1 Bear

Figure 4.2 Hunter and Deer

Figure 4.3 Boar and Pheasant

Press the key to select the following interface.

Figure 4.4 The Metric System Optical Scale

Figure 4.5 The British System Optical Scale

20

21

, The vertical dashed line corresponding to the lower left

diamond is the starting line of the horizontal axis scale.

, The horizontal dashed line corresponding to the upper right

diamond is the starting line of the vertical axis scale.

, Optical proportion line, long line is 100, 200, 300,

400 and so on. Short line is 50, 150, 250, 350 and so on. Long lines

have numerical labels, for example, the short line between 200 and

300, means 250.

Range Finder Steps.

1) Choose a reference of object, such as a bear in Figure 4.1

2) Using vertical scale

3) Default bear height is 2.4 yards/2.2 meters, choose the 2.4 yard

or 2.2 meter area, Aligning the starting line of the vertical axis scale to the top of the bear

4) Look at the position of the bear's foot on the vertical axis. In the

British system, for example, if the bear's foot is at 250, it means

the bear is 250 yards away

5) If the bear's foot is between 350 to 400, it means the bear is 375

yards away

6) In this way, the optical distance measurement is also the same.

On the left or right side of the head or on the left and right side of

the tail, use a horizontal axis ruler

Note: The above is optical probabilistic ranging, ranging accuracy is

closely related to experience, familiar with it, according to the size

and proportion of reference, the distance of the target can be

estimated. In a certain civil field, the accuracy could meet the

Image View Grade: Setting NVDevice video quality.

LOW: low video quality, WiFi image is continuous, default state.

MIDDLE: medium video quality.

HIGH: high quality video.

Note: LOW is the default state, which can meet the image quality

requirements of most users. HIGH and MIDDLE are mainly used for

video recording of high quality requirement. For normal usage,

switch to LOW mode. This mode is automatically recorded, and

takes effect when NVDevice is restarted.

Hardware decoder, Older mobile devices do not have hardware

decoder configuration, and must be set to software decoding.

Hardware decoding can reduce power consumption and system

overhead.

Quality Priority: It is normal phenomenon that WiFi video image

transmission losing data, turning on this option means image quality

is a priority, otherwise continuity is a priority.

CursorX/CursorY: Setting the horizontal and vertical offset of the

zero point for ballistic calculation, mainly used for calibrating guns,

refer to section 2.4.

Set time: Time / date of synchronous NVDevice and mobile device.

Password: Set the cursor lock password to avoid modification by

other users carelessly. See Figure 2. The original cursor lock
