Before we compare different PTZ cameras, we must determine what we need to see. We must set our objectives for the camera. For example, what detail (resolution) do we need to see? There are several different goals. We could use the military objectives defined by DRI (Detection, Recognition, and Identification, but this can get confusing. 

In the security and surveillance world, we may want to view people entering the building, or the vehicles in the parking lot. In some applications, we may be interested in reading a license plate or identifying a person’s face.

The lens zoom is one of the more important specifications for PTZ cameras. The lens is measured in focal length (mm or angle). The capability of the zoom is defined by the ratio of the smallest focal length (narrow) to largest (wide) mm settings. For example, there are 30X zoom lenses that can be adjusted between 4mm to 92 mm. The maximum zoom (or smallest angle) defines how far away we can see an object, while the minimum zoom (wide angle) determines how wide the field of view will be.

I have been asked many times, how far away can I see with that camera? Of course, that’s not the best question to ask. I can see the moon, which is over 238,000 miles away (384,000 km), but the critical question is what detail do I want to see?  The maximum focal length of the lens determines the distance we can see. With a large enough lens (around 500 mm), we can see the craters on the moon. 

PTZ Camera Low Light Sensitivity

The low-light sensitivity is crucial if we need to see things when it’s dark. We can also select a camera with an IR illuminator. The minimum illumination is the lowest light level that provides a reasonable image from the IP camera. It is measured in lux.  This can be very subjective.  It depends on what you think is an acceptable image.  The low light level image you see is not only dark but can also be very noisy.

The better quality PTZ cameras have improved low light sensitivity, with some being able to see in color as low as 0.02 lux or at 0.002 lux in BW (gray-scale). Theoretically, this camera can see things in color with the light from a full moon and can see things in gray-scale in starlight when the sky is clear.
