Go to Devices > Cameras, then open Settings for a fisheye camera. Select the correct mounting position, and choose your preferred default fisheye conversion type. Settings are saved automatically. Note that dewarping settings do not carry over to downloaded or shared clips.
Switch Dewarping Views on Timeline
In Timeline View, toggle between Default, Perspective, Four Cut, or Panoramic to suit your monitoring needs.
Overview
Fisheye cameras capture a 360-degree field of view, but the resulting image is often heavily distorted due to the ultra-wide lens. Coram’s software automatically recognizes fisheye cameras, regardless of manufacturer or resolution, and dewarps their outputs so you can interpret the scene more easily.
Dewarping applies to both live feeds and all previously recorded clips, giving you immediate improvements to your surveillance footage without additional hardware.
Start by configuring the default dewarping setting for a camera in the camera's settings menu. You can then access the dewarped view from the camera's Timeline view, where you can also quickly switch between different dewarping settings.
Note: Selecting a dewarping setting from a camera's Timeline view does not permanently change the camera's default dewarping setting. When you navigate away from a camera's timeline view, the default dewarping setting is restored automatically.
Configuring Default Dewarping Settings
Coram lets you tailor each fisheye camera’s default dewarping configuration, including its mounting position and dewarping type, to ensure accurate, user-friendly views.
Important: Selecting the correct mounting position is critical for proper distortion correction.
Access the Coram web app and sign in to your account.
From the main navigation menu, select Devices.
The Cameras tab is selected by default.
From the list, locate the fisheye camera you want to manage, and click the corresponding Settings button.
For Mounting Position, choose the option that matches how the camera is physically installed: Ceiling, or Wall.
From the Fisheye Conversion dropdown, pick your preferred default dewarping type:
Default (360° circular view, no dewarping)
Four Cut (2x2 grid of different angles)
Panoramic (flattened, 180-degree wide-angle)
Perspective (virtual PTZ-style navigation)
More information about dewarping types is provided below.
Settings are saved automatically, and changes take effect the next time you view this camera’s feed on the Timeline.
Note: If Fisheye Conversion settings are unavailable, contact Coram support.
Accessing Dewarped Views on the Timeline Page
Once you configure default dewarping settings, you can switch between different view types on the Timeline page.
Default View
Allows you to view the camera without any dewarping, showing the full 360-degree field of view in its native circular format. Useful for quickly assessing the entire area captured by the camera, and allows you to see the unaltered image for full context or when dewarping is not necessary.
Perspective View
Allows you to interactively navigate the 360-degree view using your mouse or touchscreen, similar to a virtual pan-tilt-zoom (PTZ) camera. Ideal for focusing on specific areas within the wide field of view.
Tip: Click and drag within the video frame to look around the scene, and use scroll or pinch gestures to zoom in and out.
Four Cut View
Displays four distinct views in a 2x2 grid, each showing a different angle or section of the overall scene. Useful for monitoring multiple areas simultaneously from a single view.
Tip: Each quadrant displays a different angle; click on any quadrant to enlarge it.
Panoramic View
Provides a flattened, 180-degree panoramic image of the scene. Best for getting an overall, uninterrupted view of the environment.
Tip: Click and drag within the video frame to look around the scene, and use scroll or pinch gestures to zoom in and out.

Note on Downloads and Shares
When you download or share a video clip externally from a fisheye camera, the original unaltered fisheye view is stored and transmitted. Dewarping does not carry over into the exported or shared file, so you will see the default circular image rather than the dewarped view.
