Likewise, a larger focal length makes for a narrower field of view of your surveillance cameras. According to the experience of security camera installers, if you expect your security camera to see within 40 feet, a 4.0 fixed lens security camera is enough to do the trick.

The distance that you can see on a security camera at night or when it’s dark all depends on a number of factors like resolution, location, focal length, and camera quality. The most important factor in determining how far a security camera can see is the size of the camera lens or the focal length.

The short answer is, a security camera can see from around 10m to 150m at night depending on the model.Some basic consumer products have infrared LEDs that are designed to work within short distances while professional cameras can reach much further.

How far a camera sees depends primarily on the camera's AoV, its resolution and what you want to see. As a very rough rule of thumb, the average surveillance camera you buy at a big box store, usually cannot make out facial details clearly farther than 20' away from the camera (assuming 720p resolution, 80° AoV).

Based on experience of many security experts, you can cover a 40 ft range with a 4.0 fixed lens security camera. If you need longer distance than that, use a zoom security camera, which as the name suggests, allows you to zoom in and out more. Bullet cameras usually have larger focal length while dome cameras have a shorter focal length.

To be precise, a wireless security camera can transmit at a range of 250 – 500 feet in an open environment. If you are using your wireless security camera indoors, it will cover a range of 100 – 165 feet. Remember that a wireless security camera does not work by using a video cable.

Here are some very rough rules of thumbs: To make out facial details or license plates, expect no further than ~100 meters / ~300 feet from the camera To identify a person's outline, expect no further than ~500 meters / ~1500 feet from the camera
