A video conference camera is a vital component of video‑conferencing system terminals. As a high‑tech office device, it leverages the Internet to realize virtual online meetings, remote training, business communications, video recruitment and personnel education. It enables information exchange via graphics, audio, data and other forms, bringing geographically‑distributed users together for meetings through the video conference system, and supporting real‑time long‑distance information exchange and sharing. What causes the video conference camera to output black‑and‑white images? Below is an analysis from the editorial team of Kaimorui.

The causes for black‑and‑white images of video conference cameras are listed as follows:

1. If the camera is equipped with a day‑night (color‑to‑monochrome) sensor: it delivers color images under sufficient daylight. At night or in low‑light conditions such as overcast days, it will automatically switch on infrared LEDs. The sensor will switch to monochrome mode, and consequently the captured images turn black‑and‑white.
2. Image hardware malfunctions. Faults in color data storage or transmission, as well as aging of the camera module, may result in loss of color and produce monochrome footage.
3. Poor contact of video transmission cables, namely cold‑soldered joints on circuits that receive image signals.
4. The light‑sensing component, usually a passive photoresistor or photodiode on the lamp board. If it is blocked, it cannot sense ambient light properly, which triggers the camera to switch to black‑and‑white mode.
