What does it mean when a security camera has a red dot?
If you’ve ever noticed a small red dot on a security camera and wondered what it was, you’re not alone. The red dot is actually a very important part of the security camera and has a few different purposes.
First, the red dot helps the camera to focus. Without the red dot, the camera would have a hard time getting a clear image. Second, the red dot also helps to identify which direction the camera is pointing. This is especially important if there are multiple cameras in an area.
Finally, the red dot also serves as a deterrent to criminals. If they see that they’re being watched by a security camera, they’re less likely to commit a crime. So, next time you see a red dot on a security camera, now you know what it means!
A security camera with a red dot is likely recording footage. This is because the red dot indicates that the camera is active. The footage that is being recorded can be used for security purposes or it can be accessed by the police if there is a crime that has been committed.

This is an optical artifact caused by the OLPF (Optical Low Pass Filter) in the camera between your lens and sensor. The OLPF acts like two mirrors facing each other and as the light shines through the lens and reflects off the OLPF, the red dots become more visible as you reduce the aperture on your lens.14 Jan 2020 [3]

Conclusion
It’s no secret that many modern security cameras come equipped with a red dot. But what does this red dot actually mean? Is it a sign that the camera is recording? Or is it simply a way to indicate that the camera is on and working?
The answer, it turns out, is a bit of both. The red dot typically indicates that the camera is indeed recording. However, it’s important to note that not all security cameras have this feature. Some cameras will simply display a green light when they’re on and working, without any indication of whether or not they’re actually recording.
So if you see a red dot on a security camera, there’s a good chance that it’s recording. But if you’re not sure, it’s always best to check with the company or individual who installed the system to be sure.
