Why can't the camera lens rotate?

What should I do if the Canon 70d lens is locked and cannot rotate?

1. Check the lens lock on the lens. If the lens lock is locked, the lens cannot be extended. Open that lock.

2. If the lens aperture is locked because of the user's setting, it will be very easy to unlock it by doing the corresponding operation.

I don't know what lens you used, and I can't tell you the specific location. Find it yourself. There is a lens barrel lock on the right side of the lens near the bayonet. You can turn it to the other side to enlarge it.

What should I do if the zoom ring of Nikon 200~500 lens does not turn? What if the focus ring can turn?

First, check whether your zoom lens has a lens lock, which is a locking mechanism to prevent the lens barrel from sliding out freely when the camera is not in use. If there is no such structure, then your lens is stuck and needs to be repaired.

I have this lens, and both rings can rotate. The front is the focus ring, which can rotate indefinitely. Behind it is a zoom ring, which is limited in rotation. If you can't twist left and right, then this lens must be broken. Because the 70-200II has no locking device.

There is a lens replacement button on the side of the lens, which can be rotated and twisted when pressed. Another possibility is that you screwed the screw in the wrong place. Warranty refers to the defects or failures of the camera itself, and human factors should not be covered by the warranty.

It will cost at least 300 yuan to get to Nikon's maintenance point, and the rest will be counted separately. Let's go to another maintenance department. Relatively much cheaper. If you change it, it's also for Nikon. No problem.

Turn the focus ring and zoom ring. If they are loose, take off the rubber ferrule and you will see some fixing screws around the zoom ring. Just tighten them. If the screw is often loose, the other part is at the bottom of the lens. Many lenses can be adjusted at the joint of lens barrel, and the total focusing distance is usually adjusted by elliptical holes.

Why can't the spherical camera turn its head?

1, the ball machine can't control it. First, check whether the settings of the ball machine and the video recorder are the same: address code, baud rate and protocol. Check again, whether the control line is connected properly, whether it is connected backwards, and whether the control line between the video recorder and the ball machine is connected properly.

2. If you can exercise before the power failure, it is generally not a big problem. You can see if the settings are gone and the battery of the video recorder is dead.

3. After entering the monitoring screen, you can see the roulette wheel below, which rotates the monitoring camera. Adjust the surveillance camera to the right, and you can see that the surveillance camera rotates to the right. Adjust the surveillance camera upward, and you can see that the surveillance camera rotates upward. Adjust the surveillance camera as needed.

4. Your ball machine is analog, because the network can control it as long as it can see the monitoring screen. It is one thing to simulate a ball machine, but it is another to control it, because setting the address code, baud rate and protocol on the ball machine and video recorder must be the same as setting the corresponding channel of the same ball machine.

The camera can't rotate because the bearing of the camera ball machine is damaged. You can buy new bearings for replacement or go to a professional camera shop for maintenance. The day and night mode of the camera can't be adjusted automatically, because the ball machine bearing is damaged and forced to close. You can reset it in the settings of the computer connected to the camera.

1. There is a problem with the camera application. The user turned off the camera and tried to restart it. Mobile phone storage is slow. Restore the phone to the manufacturer's settings and try to turn on the camera again. Download the third-party camera app. Brush, try to change the system by brushing. After-sales maintenance.

2. Because it is a mirror function, it cannot be flipped. If necessary, you can turn on the phone, enter Settings-Camera, turn on the mirror front lens and take a front photo. When shooting with the front camera, it is a mirror image, the size is equal, and the left and right are opposite. For example, if you make a V with your left hand, you will see a V with your right hand.

3. Try again after restarting the phone. Check whether the mobile phone system version is the latest version, and go to "Settings > About this machine/software update > (click the top version number to detect the update) and download now" to upgrade the mobile phone system version to the latest. If a third-party camera application is installed, it is recommended that you update to the latest version.

4, general reason: camera software errors or bugs make it impossible to take pictures, generally restart the phone and then turn on the camera to return to normal.

It should be that your mobile phone is locked in a certain direction, so it can't rotate automatically.

What if the monitoring pan-tilt controller can't operate the camera to rotate?

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. Click the "triangle play symbol" on the monitor screen, and the phone will start to connect the camera. After the connection is successful, the direction control button will be displayed in the lower part of the real-time screen.

(3) The bnc head of the camera is easily pulled due to the rotation of the pan/tilt, resulting in poor video line contact. Just replace the BNC head, which is the connector of the signal line, 2 yuan. The monitoring platform is out of control, as long as the agreement.

The rotating surveillance camera is mainly adjusted by the surveillance camera application, and the mobile phone opens the surveillance camera application. Click here at Mijia. When you get in, click on the connected surveillance camera. After entering the monitoring screen, you can see the roulette wheel below, which rotates the monitoring camera.

Yuntai automatic connection Yuntai automatic terminal com: Yuntai male terminal-connected Yuntai com terminal auxiliary output port camerapowerout: output+12v/ 1a DC voltage stabilization. Provide 12v camera power supply. Brush: wiper switch, providing switch control. K 1: auxiliary rib switch 1, which provides on-off control.

1. phenomenon can't make the camera run vertically. 2. Cause analysis (1) Remote controller failure. (2) Yuntai fault. 1) The control relay of control Yuntai is broken. 2) Control terminal Yuntai control line is broken. 3) Yuntai terminal is poor or poor contact. 4) The pan/tilt rotating mechanism bites to death.

The control signal is too weak. Because the function of control signal is reduced when the distance is too far, and the control signal received by the decoder is too weak, a relay box should be installed at a certain distance to amplify the control signal.

What if the camera lens can't stretch?

It collided with the camera, and the lens was slightly tilted and could not be retracted automatically. Never force it back. The lens contraction and extension work is completed by gear system, gear failure or system power failure. Methods: No matter what the reason, in order to ensure the normal use of the camera, non-professionals suggest that the camera be repaired in time.

So when the camera lens can't zoom and stretch, it should be analyzed according to its specific situation. It's best to take it for after-sales inspection and then deal with it accordingly.

If you have experience in repairing microelectronic products, you can try to disassemble the lens group. Move to the mirror ring step by step, observe carefully, and reset the mirror ring again. Special attention should be paid to those small flat cables during disassembly, which will break if you are not careful, which will aggravate the fault.

Reason one: the motor can't rotate far, and the lens can't be retracted because of insufficient power. Countermeasure: Remove the battery, and then install the fully charged battery. Reason 2: the thread of the lens guide rail is damaged or dropped out of position, and the lens cannot be retracted.

When the digital camera is turned off, the first step is to adjust the lens to the normal position; The second step is to retract the lens to the closed state. Only use the power of your fingers, and don't vigorously compete with the direction of driving the motor. When the power supply is turned off and the lens driving motor is felt to drive back, a little force is immediately applied to make the lens return to the normal position.
