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 significance 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.

However we will need to examine the pixel before looking at image resolution.

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 volume of colors in it increases as well, and the features of the picture become more distinguished. As a result, the image becomes more detailed.

Image resolution is a measure of the total of pixels that the image produced by a particular electronic device contains.

In spy cameras, this is what image resolution refers to. If we express 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.

How Should You Decide Which Resolution Spy Camera Device To Get?

The image resolution of the spy camera you are considering to buy affects you immensely. The quality of the production you will extract depends on the resolution you have. So choose wisely.

For most basic security and surveillance work a low resolution spy camera should do the work. 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. Although there are spy and surveillance cameras out there there shouldn't be any need to splash out for a camera with more than 16 Megapixels, regardless of what you're doing.

The following are some purposes for which low image resolutions would do:

• Nanny cams, where the cameras are fixed within a room.

• To detect activity at entry and exit points of buildings.

• To detect activity in children's rooms.

• For daytime surveillance.

The following are some examples of areas where you would call for a higher image resolution spy camera:

• For deployment in public spaces anywhere there are many crowds.

• For investigative purposes where you require footage for evidence.

• For traffic control and police requirements.

• For nighttime surveillance.

Spy Cameras: Questions Of 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. It doesn't matter what resolution the camera is or whether sound will be captured or not you should still check out your local statutes to make sure you won't get yourself into trouble.

So look for options with higher image resolutions. The balance should be between a good image resolution and an affordable price.
