Don't wonder about image resolution in spy security camera products! Read this blog camera resolution.
Spy cameras are electronic devices that are used to capture images of videos of places and people automatically,
i.E. Without the requirement of a human user.
They are of great use in electronic surveillance in stores and to spy upon childcare professionals such as nannies and those in daycare centers.
Image Resolution of Spy Cameras: Why It Is Useful
When you are buying a spy camera, one of the things that is of crucial interest to you is its image resolution. The image resolution is the direct measure of the pixels per square inch that the output of the camera will produce.
Before we can talk about image resolution we need to examine the pixel.
A pixel is a single unit of a picture. It contains a single color. Therefore, if an image contains a few pixels only, it will contain only a few colors and due to that, it won't be easily discernible. When an image contains more pixels, the number of colors in it increases as well, and the features of the picture become more distinguished. As a result, the image becomes more detailed.
The given image resolution is strictly the number of pixels in a two-dimensional area.
In spy cameras, this is what image resolution refers to. If we say that a particular spy camera has an image resolution of 1200 x 900, it means that it has 1,080,000 pixels in all, which means 10.8 Megapixels. This will then be the image resolution of the camera.
Image Resolution of Spy Cameras: How You Should Choose
The image resolution of the spy camera you are considering to buy affects you immensely. The quality of the output you will garner depends on the resolution you have. So choose wisely.
For most basic security and surveilance work a low resolution spy camera should do the job. But, if you want your spy camera to perform more heavy-duty work, such as pinpoint a particular person in a crowd of people, then you would require a higher resolution camera.
In commercial parlance, the image resolution of cameras is represented by a single megapixel number. For most purposes, a 4 megapixel camera would do an adequate job. However, you do get higher cameras, though almost no one should need a camera that's above 16 megapixels, even the most hardcore users.
The following are some purposes for which low image resolutions would do:
* Nanny cams, where the cameras will stay in one location with consistent lighting environment.
* To find activity at entry and exit points of buildings.
* To detect activity in children's rooms.
* For daytime surveillance.
But if you're doing one of these jobs you might want to think about getting a high resolution camera:
* For monitoring civic areas where there are many people at one time.
* For detective and investigative purposes.
* For traffic control and police requirements.
* For nighttime surveillance.
Spy Cameras: Questions Of The Law
You should note that all spy cameras are governed by laws which mostly have to do with protection of the privacy of the people they record. Check out these laws before investing in your spy cameras, however low their image resolution may be.
So look for options with higher image resolutions. The balance should be between a good image resolution and an affordable price.
