The effects look great on action camera style shots and many other subjects. Would it be possible to get example parameters for the lens distortion that would produce something similar to the above wide angle / fisheye lens images? Or should I pursue a different lens model (ex: or opencv lens distortion plugin: you for making a Lens Distortion model!

Nonetheless, we hope our review helped you understand more about fisheye security cameras in general. It’s difficult to conclude a clear winner as most of them have very different specifications catering to specific situations. We compared several fisheye cameras from various brands. On top of covering 180° and 360° angles, there are many impressive features such as infrared night vision, intelligent object detection, and many more. Also, some products offer audio/siren interfaces instead, and for these, you will have to connect them to a separate speaker/siren.ĭespite lacking mechanical PTZ functions, a fisheye security camera can cover a wider field of view without multiple cameras. These two are optional features but can add to the security and versatility of the device. However, they may not have two-way communication facilities or an integrated siren. Almost all fisheye cameras include a microphone for recording audio to their footage. The audio-based features you want to look for are the integrated siren, two-way communication, and recording audio. (whether it’s in your SD card or NVR.) So, if a 12MP camera with a 4000×3000 resolution seems unnecessary for your situation, you can go for a lower 5MP or 9MP camera. However, high-resolution footage takes up more space in your storage device. With higher megapixels, the maximum resolution of the footage will also be higher. Camera ResolutionĪ better camera with higher megapixels will be able to capture more details in the environment. As a rule of thumb, we recommend going for one that has the basic human/vehicle detection features. 0 Miniature super fisheye lens, no IR cut filter, EFL 1. There are some general features and specific ones, so consider your requirements before committing to a device. Dewarping Fisheye Displays Note: Images from Avigilon fisheye cameras are automatically dewarped. When set up in this way, the camera will send a signal when there’s motion in this specific region. They also offer tripwire and intrusion features where an area on the camera’s field of view can be customized as a virtual motion detector. Some high-end fisheye cameras boast computer vision features such as human and vehicle detection, people counting, heat mapping, and many more. Most devices can reach a maximum of 30ft and therefore will only record infrared footage that is 30ft away from them. When deciding on a fisheye camera, check for the maximum infrared distance and pick out a device that matches your requirement. It is a fundamental requirement to keep recording footage even in pitch-black environments. Nowadays, almost every security camera in the market includes infrared night vision. For most indoor applications, IPX4 is good enough. We recommend going for IP67 or at least IP6 if installing them outdoors.

It is essential if you hope to install the camera outdoors where it will become subject to dust and rain. One of the most important things to look for is the IP rating on a fisheye security camera. Audio-Based Features Decision Factors when choosing a Fisheye Security Camera IP rating
