As far as video surveillance is concerned, if you own a big property or if you want to cover a large area with fewer cameras, then the best option is to opt for wide angle security cameras. They are available in 180- and 360-degree views and are perfect for scanning a wide area to prevent any security breach. They can be deployed in areas like parking lot, a detached garage, front door, or driveway.

These cameras are always a better bet than installing multiple cameras, which can be both costly and cumbersome. Here are a few tips to choose the right wide angle security camera for your needs.

Image Distortion

Any camera that captures up to 80 degrees field of view classifies as a wide-angle camera. Super wide-angle can cover up to 180 degrees, while ultra-wide-angle boasts up to 360 degrees. In the superwide-angle cameras, image distortion is a common problem. Thus, if you want to cover the whole expanse of your home, it’s better to install two 180 degree cameras on the opposing walls rather than going with one 360 degrees wide-angle camera in the middle of the room.

Varifocal Lens Vs Fixed Lens

The varifocal lens has an adjustable focal length, angle of view and zoom, while the fixed lens, as the name suggests, has fixed parameters. Though the former is a bit expensive, it’s always better to go for a varifocal lens as you can zoom in to cover small details and zoom out to cover large areas with these. The same is not possible with fixed lens cameras. A 2mm focal length generally covers 166.9 degrees of areas in width.

Viewing Range

The focal length of the lens is directly proportional to the distance it covers. The wide angle cameras are best suited for viewing shorter distances as they have short focal lengths.

Camera Resolution

This is the most important parameter that defines the clarity of the footage. It is calculated in terms of PPF (pixels per foot). If you want to have a clear facial identification or license plate recognition, then the minimum requirement of PPF is 40. The more the pixels, the better is the clarity.

These are some of the basic things to consider when buying a wide-angle security camera. The specifications basically depend on your requirements as to where and for what specific purpose you want to install it.
