1. Stability

Most monitoring systems are required to be able to realize 7 * 24 hours long-time uninterrupted and stable operation, and the average trouble free operation time is generally required to be at least 10000 hours. Under this requirement, whether intelligent security monitoring products have high system stability is an important factor.

2. Illumination

For the monitoring system that works for a long time, the illumination of its service environment changes. For the outdoor video monitoring engineering system, it is cloudy, sunny, rainy, snowy and foggy day and night, and the outdoor lighting conditions change greatly. At the same time, it also includes strong light, reflection, backlight, shadow and other factors. As for indoor, although it is much simpler than outdoor, there are also changes in lighting conditions caused by bright and dark lights, turning on and off lights, shadows, personnel walking and so on. It has become one of the requirements of major intelligent security manufacturers to achieve better monitoring performance under various lighting environment conditions.

3. Anti fuzziness

There is a drift phenomenon in the focal length of the camera, that is, the focal length of the camera that does not move for a long time will often produce a certain deviation and will no longer maintain the original focal length value. The direct consequence of the focal length deviation is the blurring of the video image. Monitoring engineers cannot adjust the focal length of the camera at any time. Therefore, in order to achieve better video analysis effect, video analysis algorithm is required to effectively and accurately analyze the fuzzy video signal, that is, maintain good video analysis performance on the basis of fuzzy video.

4. Jitter

The installed camera cannot be stationary. In some application fields, such as the transportation industry, there are many factors that will cause slight camera jitter (such as passing by, or strong wind). This kind of camera jitter is reflected in the video, that is, the continuous jitter of the field of view, The video analysis technology of intelligent security monitoring is to locate and track the target from the video.

5. After sales service
During the installation and commissioning of intelligent security monitoring engineering products, due to their strong professionalism, professional technicians are often required for commissioning, and the parameters are specified according to the actual use environment. Therefore, users should also consider the technical support and after-sales service of the products when selecting intelligent security.
