Resolution of the CCTV camera system

Do you need a 2-Megapixel camera or an 8-Megapixel IP Camera?

There are two things to think about when selecting the camera’s resolution. the primary is what proportion detail you need across the object(s), and therefore the second factor is how wide a field of view you’d like.

Before selecting the CCTV camera system and lens, determine your objectives. The objectives include the detail you’d wish to see. for instance, does one want to ascertain an object but don’t care what it’s, or even you’d wish to identify the sort of auto or identify a person’s face. all of the objectives require a special camera, resolution, and lens.

Resolution Required Across the thing

The resolution across the thing is measured in pixels/inch (or pixels/meter). The more pixels on the target (or objects), the more detail we will see. for instance, we’d like 80 pixels across a person’s face to be ready to identify who they’re, but we’d like much less resolution to ascertain a crowd of individuals.

 IP Camera Field of View

Detection: you’d wish to be alerted if the camera sees something occupation space. during this case, you don’t care what the thing is. the space for detection depends on the dimensions of the thing and therefore the number of pixels across the thing. for instance, it’s easier to detect a truck than an individual.

Observation: This criterion provides enough resolution to be ready to see some identifying features, like the color of a person’s shirt or that an object may be a man or woman by the sort of garments they wear.
