Different Types of Security Cameras

It may be tempting to buy the most “advanced” security camera you can find. The one marketed as the highest definition footage with automatic moving gears. However, if you don’t know how it works then no matter how fancy a unit may be, chances are you can’t maximize its full potential. So, to help you, here are three basic classifications of security cameras you should know before you invest in one.

FIXED


The first and still most popular type of security camera. It works by capturing footage at a specific point it is permanently directed at. There are no gears which provide movement. To shoot at a different point, you would need to manually adjust it. Now this may seem old school, but it is still the most preferred set up because it captures stable footage and is always pointed at a specific direction.

The disadvantage of this, of course, is that it covers only a minimal area. To widen the coverage, you may need to install more units.

PAN, TILT, ZOOM (PTZ)


Unlike FIXED cameras, Pan, Tilt, Zoom or PTZ is created with moving gears that allows it to move in three different ways. It can be remotely operated or set up to automatically move around. This allows for greater area coverage. PTZ can also be used to follow the movement of a subject which makes it a preferred type for surveillance purposes.

The problem with PTZ cameras though is that it may not efficiently capture details. The zoom feature, although helpful in focusing on specific points, decreases the covered area. And as it moves around, it creates blind spots which may be exploited by intruders.

360 Degree


Also known as Virtual PTZ, 360-Degree is the camera type with the most coverage. It is made up of several high-res fixed cameras pointing at different directions compacted in a single housing. This usually assumes the dome type of housing to be able to capture different points at the same time. It automatically stitches the footage together to create a 360-room view. 360-Degree cameras also have a zoom feature.

360-Degree cameras may seem like the best option. However, it is also the most expensive and the heaviest on data storage. Obstructions can also easily render this type because of blind spots. To maximize its use, place it in a room with minimal to zero obstructions to have a full room view.
