What is the Purpose of the Red LEDs around a CCTV Security Camera?
The small red lights around CCTV (Closed Circuit Television) cameras are typically infrared (IR) LEDs (Light Emitting Diodes). These IR LEDs are used for a specific purpose: to provide night vision or low-light visibility for the camera. You may also notice an LDR (Light Dependent Resistor) between LED lights used as a light sensor for dusk-to-dawn operation. This means the LEDs turn on in the evening and turn off in the morning by detecting sunlight.
Here’s how the IR lights in a security camera work to provide night vision allowing it to capture clear images and footage in low-light or dark conditions.
CCTV ආරක්ෂක කැමරාවක් වටා ඇති රතු LED වල අරමුණ කුමක්ද?
CCTV (Closed Circuit Television) කැමරා වටා ඇති කුඩා රතු ආලෝකය සාමාන්‍යයෙන් අධෝරක්ත (IR) LED (ආලෝක විමෝචක ඩයෝඩ) වේ. මෙම IR LED විශේෂිත අරමුණක් සඳහා භාවිතා වේ: කැමරාව සඳහා රාත්‍රී දර්ශනය හෝ අඩු ආලෝකයේ දෘශ්‍යතාව සැපයීම සඳහා. සන්ධ්‍යාවේ සිට අලුයම දක්වා ක්‍රියාකාරිත්වය සඳහා ආලෝක සංවේදකයක් ලෙස භාවිතා කරන LED විදුලි පහන් අතර LDR (ආලෝකය රඳා පවතින ප්‍රතිරෝධකය) ද ඔබට දැකගත හැකිය. මෙයින් අදහස් කරන්නේ හිරු එළිය හඳුනා ගැනීමෙන් සවස් වන විට LED ක්‍රියාත්මක වන අතර උදෑසන අක්‍රිය වීමයි.
ආරක්‍ෂිත කැමරාවක ඇති IR ලයිට් රාත්‍රී දර්ශනය සැපයීමට ක්‍රියා කරන ආකාරය මෙන්න, අඩු ආලෝකයේ හෝ අඳුරු තත්ත්‍වයේ දී පැහැදිලි රූප සහ දර්ශන ග්‍රහණය කර ගැනීමට ඉඩ සලසයි.
Why Cctv Camera Has Red Light?
CCTV cameras are installed in many places for security reasons, but sometimes they can be a source of confusion. One common question is why some CCTV cameras have a red light. The red light is a indicator that the camera is on, and it is working properly. It is important to note that not all CCTV cameras have a red light, as some have a green light or no light at all. The red light is simply a feature of some CCTV cameras, and it is not necessary for the camera to function properly.
The red light on a CCTV camera is typically located on the back of the camera, and it is usually a small red light. In some cases, the red light may be located on the front of the camera, and it may be a larger light. The size and location of the red light can vary depending on the camera.
The red light on a CCTV camera is usually a feature of analog cameras, as digital cameras do not typically have a red light. However, some digital cameras may have a red light, as it can be useful in indicating that the camera is on and working properly.
If you have a CCTV camera with a red light, it is important to note that the red light is not necessary for the camera to function properly. If the red light is not on, the camera will still work, and you will still be able to see what is happening in the area that the camera is covering. However, if the red light is on, it can be a useful indicator that the camera is working properly.
