I forgot the password of the surveillance video. How can I get it back?

Because the camera is also networked and needs to add a password, it is necessary to reset the camera password. Some have a reset button, some may need to be activated after reset, and some can be used directly. Monitoring camera is a semiconductor imaging device, which has the advantages of high sensitivity, strong light resistance, small distortion, small volume, long life and vibration resistance.

Another way to solve this problem is to ask the manufacturer's technology. General manufacturers need to use special client software to search the IP of the camera, and then start to restore the initial value, enter the password calculated by the manufacturer, and click OK. Please consult the manufacturer's customer service for specific operation methods.

Using the system time of the video recorder to generate a temporary password, you can log in to the system and then reset the password by restoring the factory settings of the video recorder. If the camera has a physical button to restore the factory settings, just press and hold 10 second.

Calculate the password according to the code. If there is no code, you can only use tools to recover the password in the LAN, enter REGEDIT, and then look for the user name string, next to the password or the word password. If it really doesn't work, use an initialization tool in the monitoring system to initialize.

Extended data:

The close-up ability of the lens is another key point after the focal length and the maximum aperture.

The same is true for wide-angle lenses, standard lenses and telescope heads.

So, how big is the close-up ability?

First of all, the close-up ability of a wide-angle lens has almost nothing to do with the wide-angle lens, but when shooting a flower scene with a vast landscape as the background, it is often necessary to shoot the flowers a little bigger. In similar circumstances, the close-up ability of a wide-angle lens is very important.

The close-up capability of the existing 50mm standard lens is about 1 125px, which basically meets the requirements.

However, when the shortest shooting distance is used, the large-aperture standard lens often produces large aberration because of the lens protrusion, resulting in low imaging quality. We should be prepared for this when buying and using.

When many people choose a lens, the first concern is the clarity of the lens.

The purpose of the photo determines what kind of sharp lens is needed.

High-priced high-quality lenses are mainly used by professional photographers. If it's just general photography, there's no need to spend a lot of money on expensive and high-quality lenses.

In addition, the imaging clarity of the lens is directly related to the aperture size. When a lens is reduced by one or two steps from the maximum aperture, the imaging clarity will be greatly improved.

Distortion is an optical phenomenon caused by the optical properties of lenses. It's impossible that every shot has no distortion. Manufacturers have corrected the distortion when producing lenses, trying to control the distortion to the lowest level.

Generally speaking, there are three kinds of lens distortion: barrel distortion at the wide-angle end of zoom lens, pincushion distortion at the telephoto end and hat distortion after barrel distortion correction at the wide-angle end.

At present, the most prominent problem of the lens is the barrel distortion at the wide-angle end. Try to choose a style with small barrel distortion when purchasing.

In backlight photography, halos and light spots will be formed on the screen due to the repeated reflection of strong sunlight or other strong light sources on the mirror.

This small part of the light that forms halo and flare will not be imaged on the screen, but will also form random reflection in the layout, which will reduce the imaging quality.

In order to prevent this phenomenon, backlight photography must use a hood.

Excellent lens adopts the process of completely preventing halo and glare in the manufacturing process, and the contrast is good even if it is shot in reverse light.
