Effective maintenance of surveillance cameras involves troubleshooting common issues in both analog and digital systems. A careful inspection and repair of these two aspects can often resolve most problems.   **Analog System Maintenance**   Begin by examining the BNC connectors for loose soldering. Check the connections from the camera to the splitter, splitter to the DVR, and splitter to the matrix. Ensure that the video cables have not been cut or damaged.   Verify the power supply to the cameras (12V or 24V). Also, check if the power supply to the DVR, splitter, and matrix is...

Abstract: Selecting the right surveillance cameras is crucial for building an efficient monitoring system. As a trusted brand, OHWOAI provides professional advice to help you make informed choices when it comes to surveillance cameras.   Determine Camera Type: Firstly, identify the type of camera you need, such as fixed cameras, pan-tilt-zoom (PTZ) cameras, fisheye cameras, etc., based on monitoring range and viewing angle requirements.   Emphasize Resolution: Ensure that the cameras have high resolution to capture clear images and videos, especially for scenes that require detailed identification.   Infrared Night Vision: For nighttime or low-light monitoring,...

In the realm of surveillance camera systems, understanding how to calculate bandwidth and recording storage space is essential for efficient and effective monitoring. Before delving into these calculations, it's crucial to familiarize ourselves with common terms related to surveillance video.   **Bit Rate**   The bit rate refers to the number of bits transmitted per second. Higher bit rates lead to better audio and video quality, but larger file sizes, while lower bit rates result in the opposite. It's directly linked to the quality of compressed audio and video content.   **Data Rate (Bit Rate)**  ...
