In the field of photography, SLR cameras have always been highly respected. With their excellent image quality and powerful functions, they have become the first choice of many photographers. . However, unlike digital cameras, SLR cameras need to be connected to computers and monitors for better shooting and post-processing.
There are two main ways to connect SLR cameras, one is through USB data cable, the other is through HDMI cable. These two connection methods have their own characteristics and can be selected according to actual needs.
Using a USB data cable to connect a DSLR camera can achieve a variety of functions, such as image transfer, remote control and shooting. Just plug the USB data cable into the camera's USB port, and then plug the other end into the computer's USB port to transfer data.
After connecting, you can use the corresponding software to control the camera for shooting, set parameters, view real-time images, etc. This is useful for situations where long exposures are required or time-lapse shots are required. You can sit in front of the computer, set the parameters through the software, and then click the button to shoot without touching the camera directly.
In addition, the USB connection can also conveniently connect the camera with image processing software on your computer. Whether it is post-processing after each shot or viewing the shot in real time, it can be done directly on the computer via USB connection. This way, you can adjust, edit and save your photos more easily.
If you pay more attention to the display effect and want to watch the shooting in real time, then connecting the SLR camera via HDMI cable is a good choice. The HDMI interface can transmit high-definition images and audio signals, and can perfectly display camera images on a computer monitor.
The connection method is also very simple, just plug one end of the HDMI cable into the HDMI interface of the camera and the other end into the HDMI interface of the computer. After connecting, you can use the corresponding software to watch the camera's screen in real time to ensure that the shooting effect meets expectations.
HDMI connection also allows simultaneous monitoring and recording during shooting. If you need other people to evaluate the photos in real time while shooting, or need to record videos for post-editing, it will be more convenient to connect via HDMI.
Whether it is connected through USB or HDMI, when using a DSLR camera to connect to a computer monitor for shooting, you need to pay attention to the following points:
Stable connection: Make sure the connection is stable and reliable to avoid affecting data transmission and pictures. quality. Choose good quality data cables and adapters, and keep the interfaces clean. Appropriate resolution: Set the camera's output resolution according to the resolution of your computer and monitor to get the best image results. Adjust the display effect: Adjust the image output by the camera according to actual needs and personal preferences. You can adjust brightness, contrast, color and other parameters to obtain more ideal shooting effects. Protect privacy: When using public places, pay attention to protecting personal privacy and intellectual property rights. Avoid secretly photographing or photographing confidential locations without the permission of others.Connecting a computer monitor for shooting not only provides better observation and control, but also facilitates post-processing and editing. Whether you are a professional photographer or a photography enthusiast, you can use a reasonable connection method to shoot with a SLR camera more conveniently.

If your monitor is LCD, it is a problem with the monitor, because LCD and flat screen are different. Flat screens generally support 85 Hz, while LCDs generally support 60. It is normal and some support 75, but it is best to use 60 Hz. It will not damage the monitor. If your monitor is flat, then there is a problem with your graphics card driver
The frequency of computer monitors is only meaningful in the early CRT monitors. On CRT monitors above 75 Hz, the eyes will not feel the screen flickering (to protect the eyes). Nowadays, monitors are basically LEDs. LCD screens are usually 60HZ. Some of them display 59. LED displays have no meaning to the frequency... Usually the default is 60. Don’t worry. There is no way to increase it.
Generally speaking, the video data of the surveillance system will not be deleted easily. There is a system that automatically deletes the video, but there is a time limit. For example, after 2 weeks of recording, the original video will be overwritten to make room for another recording. Because if it is deleted easily, the meaning of monitoring will be lost. For example, it is unreasonable if an employee commits suicide and deletes it easily after doing something, or if the relevant leader deletes it at will. If it must be deleted, ask the manufacturer for help and explain the reasons before deleting it. The monitoring system recommends that you configure it like this:
1. A 4-channel video capture card, plugged into the computer motherboard, which costs a few hundred yuan
2. A dedicated surveillance camera, which is cheap at about 100 yuan , the slightly more expensive one costs a few hundred yuan, and the high-end one costs tens of thousands, so it is not necessary for community or factory monitoring.
3. Special monitors for security monitoring cost more than 1,000. If you want to save money, use a computer monitor instead. However, monitors are not as effective as monitors and have a shorter lifespan. It is better to use professional monitors for monitoring.
