Select the sort of Surveillance Camera
- IP Camera System
There are many various sorts of IP cameras with different prices. You can check out the IP Camera price in BD to find your suitable CCTV system. One camera doesn’t fit every application. for instance, you don’t want to pick an outside CCTV system if you propose to use the camera inside. Why pay more for something you don’t need.

There are Panoramic cameras that will view 360-degree, and PTZ cameras that include long-range lenses so you’ll view a car place many feet away.
Don’t forget that the video and management system is an integral part of your closed-circuit television.
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
These objectives are classified by the acronym DORI (Detection, Observation, Recognition, and Identification). The old classification was DRI (Detection, Recognition, and Identification). DRI was employed by the military using thermal cameras to look at tanks, trucks, and enemy soldiers. DORI is that the updated definition used for general surveillance applications.
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.
Recognition: This class provides enough resolution to be ready to identify an individual that’s known to you. the popularity is predicated on the garments they wear and possibly how they walk. This level of pixel coverage allows you to spot a car place.
Identification: This resolution provides enough detail to be ready to recognize a person’s face you don’t know.
Resolution and Field of View
Once we all know what percentage pixels we’d like across an object, we will decide what percentage of those objects we will see simultaneously (in the sector of view). The resolution of the IP camera determines the width of the sector of view. the upper the resolution, the broader the world we will see.
Many IP cameras are available with sensor resolutions between 2-Megapixels to over 12-Megapixels. Please read the simplest IP camera for Your Application for more information about the proper IP camera.
The Right Lens for the IP Camera
The lens determines how distant you’ll see an object.
Today we use the lens angle to work out the camera’s distance and field of view. The smaller the angle, the upper the magnification. Lenses are usually included with the IP camera, so you would like to seem at the camera specifications to form sure you get the proper camera and lens.
