How to adjust the continuous movement of the camera

How to control the rotation direction of the surveillance camera?

Hello, first of all, you need to scan the QR code at the bottom of the camera with your mobile phone and download and install the mobile phone control app.

Click to open the mobile phone application.

Enter "triangle play symbol" on the monitoring screen, and the phone will start to connect to the camera.

After the connection is successful, the direction control button will be displayed in the lower part of the real-time screen.

Click the direction control button, and the camera will rotate to complete the operation.

I hope the above answers can reach you, and hope to adopt them!

First, stabilize the machine.

1. It is best to hold the camera with both hands, which is definitely more stable than one hand, or use something that can be supported by you or prepare a camera tripod. In any case, it is to minimize the shaking of the picture, and it is the most taboo to shoot while walking, which is also the most common mistake. This shooting method is only used under special circumstances. It must be remembered that the stability of the picture is the first requirement of dynamic photography.

2. Keeping the picture stable is the most basic and important requirement for shooting. Whether it is pushing, pulling, shaking, moving, leaning, tilting, zooming, etc. We always work around how to keep the picture stable. The main factor affecting the stability of the picture comes from the stability of the photographer. Mastering the correct method of holding a camera is a basic skill for every photographer. Only with excellent basic skills can you operate freely when shooting and shoot high-level video works.

Second, fix the lens.

1. Simply put, after the lens is aimed at the target, shoot at a fixed point, instead of zooming in and out or sweeping up, down, left and right, set the screen size and start recording. Usually, the fixed lens is the main shooting mode, and there is no need to do too much zoom action, so as not to affect the stability and change of the picture, that is, the size and depth of field of the scene are changed by the difference of the viewing size or angle and position.

2. To put it simply, when shooting a panorama, the camera leans back a little, and when you want to shoot a part, the camera leans forward a little. If the position changes, such as the side, height and lower position, the effect will be different and the picture will be richer. If you can't get close because of the venue, of course, you can use the zoom lens to adjust the picture to the size you want, and the adjustment range can be slightly smaller.

3. But remember not to stand at a fixed point and zoom in and out with a zoom lens, which is a common problem for many V8 people. Using more fixed lenses when shooting can increase the stability of the picture. When shooting one picture at a time, connect pictures of different sizes and make the pictures bigger and smaller with less zoom. Unless you fix them with a tripod, long-distance zooming will definitely lead to picture jitter.

Third, shooting skills

1. I believe you have also encountered a picture that can't take a panoramic view of the scene. At this time, you must scan the camera from right to left or from left to right, which is one of the advantages of the camera. But when many people do this action, the picture often swings from side to side or is fast and slow, in short, it looks very unsmooth. These problems mainly occur in the wrong way of body rotation, or the rotation angle is too large, which leads to hesitation and cannot be achieved overnight.

2. The correct way is to take the waist as the dividing point, with the lower body motionless and the upper body moving. Just like when you want to cross the road, look around to see if there is a car coming. It is reasonable to turn your head left and right below your shoulders. For example, if you want to shoot a scene, you need to scan from point A to point B. First, turn your body to point B, and then turn your upper body to point A. At this time, the camera is facing the direction of point A, and then press the video button to place it first.

How to move multiple images of the camera

As follows:

1. Just unplug the third video head and the first video head behind the hard disk video recorder and change their positions.

2. If computer monitoring is used, and there is an acquisition card in the computer, just change the position of the video head inserted in the acquisition card to the back of the computer.

3. If the monitor is directly connected, please restart the hard disk drive. If only the display is turned off, turn on the display.

4. If you are connected through a network, you can generally click on the preview device and find the corresponding device. Just right-click and open all the menu points that appear.

Scheme 1: Using NVR homologous output is suitable for the scene where two monitors output and display at the same time, and the monitors are close to the video recorder:

Description: HDMI and VGA are not suitable for scenes where the monitor is far away from the video recorder. The display pictures of the two monitors are exactly the same, so it is impossible to define the picture layout separately.

Scheme 2: the output with screen splitter is suitable for the scene where the monitor is close to the video recorder and can be connected through HDMI/VGA cable:

Description: The transmission distance between HDMI and VGA is greatly affected by the quality of wire. _ No, no, no, no, no, no. ..

Insufficient: HDMI and VGA have short transmission distance, which is not suitable for the scene where the monitor is far from the video recorder. Each monitor displays exactly the same picture, so it is impossible to define the picture layout separately.
