How Far We Can See With the PTZ IP Camera

Thermal and Optical Security PTZ Camera

How far away can we see things using a long range PTZ camera? Obviously, we can see the moon which is 238,900 miles away, but of course we would need a powerful telescope to see the small craters.  We can see people in a crowd, but when we want to identify their face, it gets a lot harder.  The distance is determined by what detail we need to see.

Do you want to be able to detect a vehicle moving, or identify the person driving the vehicle?  The objective will determine the type of IP camera system you will need. In general the distance is determined by the lens, the type of camera (thermal camera or optical camera), the camera resolution, and sometimes the IR illuminator available.  This article describes how we can specify the IP camera system required for long distance viewing.

Long Range IR PTZ Cameras – How Long is Long?

IP surveillance cameras are ubiquitous today. Everyone who sets foot out his door is well aware that somewhere, sometime on his journey he will enter into and out of several cameras’ fields of view.

Since very few everyday security cameras are covert, one has only to look several feet up at buildings, light poles, retail store ceilings to see this is true. There is a reason for this –  the sight of a surveillance camera can be beneficial in deterring crime.

But there are also cameras capable of surveying an area, sight unseen,  from, literally, miles away. These surveillance cameras fall under the heading, long-range cameras.
