Fisheye Cameras: Pros and Cons Leave a comment

When comparing the different types of surveillance cameras, one type of camera that may come up are fisheye cameras. These cameras are not commonly used, but they can have many benefits. But with anything, there are a few cons to keep in mind as well.

Fisheye Camera Pros

Panoramic Surveillance

The biggest benefit of fisheye cameras is that they are able to capture a wider view. There are different types of fisheye lenses, but all of them can capture angles of at least 180° and some can go up to 360°. Regular cameras are not able to capture panoramic images which means that they are more susceptible to having blind spots. In order to remedy this issue, more cameras would need to be installed to capture more angles. Since fisheye cameras have a wider angle of view, they have less blind spots which means less cameras needed.

PTZ Capabilities

PTZ stands for pan, tilt, and zoom. Since fisheye cameras are able to capture wider angles, users can pan, tilt, and zoom in on recorded footage to evaluate incidents. PTZ cameras do exist, but these features can only be used in real-time, not on footage that has already been recorded. Fisheye cameras can use PTZ capabilities on live or recorded footage.

Tamper Resistant

Like dome cameras, these cameras are protected by an external casing. Since there’s a covering on the lens, it is difficult for someone to get access to the camera inside and tamper with the angle. In addition, the dome shape prevents people from grabbing onto it and disconnecting it.

Night Vision

Since these cameras are able to capture a wider view, they are common for outdoor use to monitor parking lots and large areas. Because of this, most fisheye cameras are made to withstand harsh weather. In addition, many are equipped with infrared (IR) lights so they can function in darkness.

Fisheye Camera Cons

Lower Resolution

The main reason why people opt to use fisheye cameras is because their range of view is wider. However, a wider view means a lower resolution. This means that recorded images can look blurry or pixelated. Fisheye cameras do capture more areas, but in return, image detail is sacrificed.

Image Warping

A common issue with using fisheye lenses is that the image will appear warped. Since it captures a panoramic view, the image can take on a curved appearance and be distorted. In order to fix this issue, fisheye images will need to be dewarped.

Wrap Up

These types of cameras would be a good option for those that want to monitor large outdoor areas. However, you should remember that capturing a panoramic view will produce a lower quality and distorted image.
