The most basic debugging method for video recorders

It depends on what brand of VCR you have.

1. You should choose DVR DVR DVR can be an 8-way plus a 16-way DVR, so that two days is enough.

2. If it is installed in the unit, most of it is indoors, and it should be generally installed in the passage corridor and various entrances and exits, stairs or elevators, so the camera of the ceiling hemisphere can be generally selected.

3. Two DVRs, each of which can be equipped with two 1T hard disks, two monitors, consoles, and UPS power supply if the fruit is distributed.

4. It is best to use the ceiling hemisphere, which is also trouble-free, the power supply and the line can be hidden in the ceiling, which is easy to install and maintain, and the power supply can be powered by 12V front-end power supply or 12V high-current back-end centralized supply of slow electricity.

6. For long distance, used outdoors, you can use a camera, only for units, generally 75-5 lines can meet the distance requirements, there is no need to use optical fiber.

1.According to the camera monitoring distance, determine the area that each camera needs to monitor, thereby determine the installation position, install the camera bracket at the position, and the indoor can choose to punch holes in the wall, and the outdoor can choose to install the monitoring pole.

2.Fix the camera to the bracket and start wiring, the surveillance camera has a power line and a signal line, all need to be connected to the liquid potato residue, one section of the line is connected to the camera, and the other end is connected to the hard disk video recorder, after the wiring is completed, check whether the bracket screws and camera screws are fixed, and the outdoor camera must be installed with a waterproof camera.

3.After the installation of the surveillance camera, the surveillance camera is debugged, the focus of the debugging is the focus of the camera, first of all, we turn off the shutter and backlight compensation switch on the camera hand zen, turn on the power, and then adjust the direction of the camera to make it aim at the monitoring area; Then adjust the aperture of the lens, and while dimming the aperture, pay attention to the picture on the monitor and adjust it until the picture clarity is the best; Finally, install the camera shield and secure the bracket. Pay attention when debugging:

The aperture of the camera should be as wide as possible but not white, and the illumination should be adjusted to the maximum in the live environment, that is, until it is bright.

The above is the installation and commissioning tutorial of the camera, in addition to the installation of the camera there are some specifications, let's take a look: first of all, the installation height requirements, which are not less than meters indoors, not less than meters outdoors, so as to meet the monitoring requirements, at the same time the monitoring line wiring should be installed reasonably, safe, the monitoring camera pipe wiring has two kinds of open and dark matching, and the open piping requires horizontal and vertical, neat and beautiful. In addition, it is necessary to pay attention to the quiet placement of surveillance cameras and their supporting equipment, such as lenses, camera shields, brackets, wipers, etc., which need to be installed firmly to ensure the normal operation of the camera.

Loosen the fixing screws of the rear focus adjustment ring of the surveillance camera (there are also some cameras that are adjusted directly by adjusting the screws on the side);

Adjust the zoom lens to the maximum telephoto position, and use the focus ring on the lens to set the focus until the most spine of the image is clear;

Adjust the zoom lens to the maximum.

Loosen the fixing screws of the rear focus adjustment ring of the surveillance camera (there are also some cameras that are adjusted directly by adjusting the screws on the side);

Adjust the zoom lens to the maximum telephoto position, and use the focus ring on the lens to set the focus until the image is the clearest.

Adjust the zoom lens to the maximum wide angle.

The main thing to adjust the surveillance camera is to adjust the focus of the lens. First turn off the shutter and all switches on the camera, then aim the camera at the monitored area, then adjust the aperture of the lens, and look at the image on the monitor until the image is at its best.

After the surveillance camera is installed, it needs to be reasonably debugged, how to debug the surveillance camera in place? What are the steps for debugging surveillance cameras?

1. How to debug the surveillance camera.

1. Debugging the surveillance camera is mainly to adjust the focus of the lens. First of all, we need to turn off the shutter on the top of the camera and the switch for backlight compensation, aim the camera at the monitored area, and then adjust the aperture of the lens. Look at the image on the monitor while tuning, and if the image is optimal, it means that it fits.

2. When adjusting the aperture of the lens, open it to the maximum as much as possible, and the image should not appear whitish. In the on-site environment, the illumination should also be adjusted to the maximum, that is, until it is bright. Finally, we install the protective cover, and we also need to fix the bracket to complete the whole commissioning process.

The whole picture is monitored, and it is very clear.

Second, what are the precautions for installation monitoring.

1. The requirements of location are very critical, for some surveillance cameras, the quality of the location will directly affect its imaging effect. Therefore, in order to achieve a better installation site, the placement is very critical. The installation of the camera should not be disturbed by the surrounding environment, and at the same time, the camera should be installed as much as possible.

Meters from the ground, if it is outdoor monitoring equipment, at least more than 3 meters, in order to effectively protect the camera, and the later maintenance is more convenient.

2. It is also necessary to pay attention to the problem of angle, and the current cameras mainly have barrel type and hemispherical shape. The hemispherical type is more suitable for indoor use, and the size is relatively small, so it can be installed on the wall or ceiling. But after installation, you also need to adjust the angle.

3. The installation of surveillance cameras also needs to pay attention to electricity safety, generally speaking, wires need to be provided separately, and waterproof treatment is also required. A waterproof box should be installed on the camera outside the barricade, and attention should be paid to lightning protection to prevent lightning strikes.

Summary: To install the camera, you need to do a good job of debugging, according to the angle and environment, and you also need to adjust the monitoring aperture and focus.

The following points need to be paid attention to in the debugging of the camera:

1. Unscrew the rear focus adjustment ring of the surveillance camera to make silver fixed screws (some cameras are directly adjusted by adjusting the side screws);

2. Adjust the zoom lens to the maximum telephoto position, and use the Hu Hu leak focus ring on the lens to set the focus until the picture pants are the clearest;

3. Adjust the zoom lens to the maximum wide angle (wide short focus, the number of millimeters of the lens is the smallest at this time, and the object seen through the camera is also the smallest), and rotate the back focus adjustment ring until the image is the clearest;

4. Repeat steps 2 and 3 until the image remains in focus when transitioning from telephoto to wide-angle. After the setting is complete, tighten the back focus adjustment ring.

The debugging of the camera needs to pay attention to the following early failures: 1. Loosen the fixing screw of the rear focus adjustment ring of the surveillance camera (there are also some cameras that are directly adjusted by adjusting the screws on the side); 2. Adjust the zoom lens to the maximum telephoto position, and use the focus ring on the lens to set the focus until the image is the clearest;

3. Adjust the zoom lens to the maximum wide angle (wide short focus, the number of millimeters of the lens is the smallest at this time, and the object seen through the camera is also the smallest), and rotate the back focus adjustment ring until the image is the clearest; 4. Repeat steps 2 and 3 until the image remains in focus when transitioning from telephoto to wide-angle. After the opening and opening collapse is completed, tighten the rear focus adjustment ring.

1. Unscrew the fixing screw of the rear focus adjustment ring of the surveillance camera (some cameras are directly adjusted by adjusting the screws on the side);

2. Repeat steps 2 and 3 to keep the image in focus when switching from telephoto to wide-angle. After the setting is complete, tighten the back focus adjustment ring.

3. Adjust the zoom lens to the maximum wide angle (wide short focus, the number of millimeters of the lens is the smallest at this time, and the object seen through the camera is also the smallest), and rotate the back focus adjustment ring until the image is the clearest;

4. Adjust the zoom lens to the maximum telephoto position, use the focus ring on the lens to set the focus, and crack the imitation to the maximum clarity of the image;

Hope it helps!
