Network cameras are common security‑protection products in daily life. Many people may not know much about them. However, with technological advances, network cameras are gaining increasing popularity and are applied in nearly every aspect of our lives. When using network cameras, users may occasionally notice unsatisfactory image quality. What factors can affect the performance of a network camera? Below, our editor from Kaimorui will explain this in detail.

The performance of network cameras is affected by the following factors:

Image Format: Different image formats deliver different pixel counts and produce recording files of varying sizes.

Dual‑stream: Some network cameras are designed to support two video signals, known as dual‑stream. The advantage of dual‑stream is that one stream can be used for live viewing while the other for recording. Compared with using a single stream for both viewing and recording, this mechanism effectively prevents network congestion and ensures smooth video transmission within limited network bandwidth.

Edge‑side Storage: Certain network cameras come with an SD‑card slot or a USB removable‑storage port, which is referred to as edge‑side storage. Edge‑side storage is frequently deployed in surveillance environments with insufficient bandwidth. For sites where broadband access is unavailable, edge‑side storage can save surveillance recordings to maintain monitoring capabilities, which serves as a practical alternative solution.

Frame Rate: Every video file consists of successive still images; each single image is called one frame. For example, if one second of video is composed of 25 consecutive images, the frame rate is 25 frames per second. Under the PAL standard, 25 frames per second can render movements very realistically. If the frame rate drops below 25 fps, motion in the video will appear choppy. The lower the frame rate, the less fluid the motion, and jerky playback artifacts may even occur.

After reading the above content, you should have an understanding of factors influencing network‑camera performance. Besides the points mentioned above, key parameters also include infrared night‑vision capability, low‑light sensitivity, wide dynamic range, and strong‑light suppression.
