Security cameras do not typically emit visible light at night. Instead, they use infrared technology to capture images and videos in low light or no light conditions. These cameras are equipped with built-in infrared LEDs (Light Emitting Diodes) that emit infrared light, which is invisible to the human eye. When the camera switches to night vision mode, these LEDs turn on and shine a spotlight of infrared light on the area being monitored.
The use of infrared light allows security cameras to provide night vision capabilities without alerting potential intruders or disturbing the surrounding environment. This is particularly important for security purposes, as it enables the cameras to continue capturing footage even in complete darkness. Since the infrared light is not visible, it does not give away the presence of the camera or draw attention to its location.
I have personally experienced the effectiveness of infrared night vision on security cameras. At my workplace, we installed security cameras with night vision capabilities to monitor the premises during both day and night. During the night, the cameras would switch to night vision mode, and we were able to clearly monitor the area even without any external lighting. This was especially useful in areas where there were no streetlights or other sources of light.
It’s worth noting that the range and quality of the night vision capabilities can vary depending on the specific camera model. Some cameras may have a shorter range and capture lower quality images in the dark, while others may have a longer range and produce clearer night vision footage. It’s important to consider these factors when choosing a security camera for your specific needs.
