Have you ever noticed a strange phenomenon while using your phone near a security camera? You may have seen that the light on your phone screen or camera flash suddenly goes off or flickers when you are in the vicinity of a security camera. It may be a perplexing experience, but there is a plausible explanation for this occurrence.
When security cameras are designed, they incorporate infrared (IR) sensors to capture any movements or activities in their field of view, even in low light conditions. These sensors emit IR light that is invisible to the naked human eye but can be detected by the camera. The purpose of this is to capture a clear and detailed image, even in situations where the ambient lighting is inadequate.
Here comes the connection with your phone. Many modern smartphones also come equipped with an infrared light emitter. This feature is primarily used for facial recognition or depth-sensing technologies, such as the ones used in augmented reality applications. When the phone’s IR emitter coincides with the security camera’s IR sensor, it can cause the camera’s sensors to misinterpret the emitted light as an input signal, resulting in unexpected behavior such as your phone screen flashing or the camera flash activating.
So, the next time you notice your phone’s screen or flash behaving unusually while in the presence of a security camera, rest assured that it is not a mysterious glitch or a hidden feature. It is simply the result of your phone’s IR emitter interacting with the IR sensors found in security cameras, creating a momentary disruption in their usual functionality.
Reasons for phone flashing on security camera
Having your phone flash on a security camera can be a perplexing situation. There are a few potential reasons why this may occur:

Overall, camera interference and reflection can be potential reasons why your phone flashes on a security camera. By taking steps to minimize interference and reflection, you can help ensure the proper functioning of security cameras without any unexpected flashes from your phone.
Camera sensitivity to IR light
Security cameras are designed to capture clear and detailed images, even in low light conditions. One of the ways they achieve this is by using infrared (IR) light. IR light is invisible to the human eye but can be detected by security cameras, making it ideal for capturing images in the dark.
When a security camera detects IR light, it activates the infrared LEDs located around the lens. These LEDs emit a beam of IR light, which helps illuminate the area being monitored. The camera lens then focuses this light onto the image sensor, which captures the scene and converts it into an electronic signal.
The camera’s sensitivity to IR light can vary depending on its design and settings. Some cameras have a higher sensitivity, while others may require a stronger source of IR light. The sensitivity can also be adjusted manually or automatically, depending on the camera model.
When a phone’s flash goes off in the vicinity of a security camera, it can trigger the camera’s IR sensors. This is because the flash emits a burst of light that includes a component of IR light. While the flash may appear bright to the human eye, the IR light component is typically not visible. However, security cameras can detect it and may interpret it as a source of IR light.
This detection of IR light from a phone’s flash can cause the security camera to activate its own IR LEDs, resulting in a temporary increase in brightness in the camera’s field of view. Depending on the camera’s settings, this increase in brightness may be more noticeable or may only result in a subtle change in the image captured.
It is important to note that the sensitivity of security cameras to IR light can vary, and not all cameras will be triggered by a phone’s flash. Additionally, the range of IR light emitted by a phone’s flash is usually limited, so its effect on a security camera may be restricted to a relatively small area.
