💡 At a Glance
Coram dynamically adjusts video streaming quality based on context, and storage quality based on motion detection. Single-camera Timeline views can display high-definition (HD) video using the camera’s native resolution, while multi-camera displays default to standard definition (SD) to conserve bandwidth.
⚡ Key Takeaways
Adaptive Streaming Quality
For multi-camera views (Live View, Kiosk, and Personal Wall) Coram uses SD to maintain smooth performance. In a single-camera Timeline view, for recordings where motion is detected, you can switch to HD for detailed playback.
Motion-Triggered Recording
Footage without motion is stored in SD to save resources. When motion is detected, Coram stores both SD and HD versions, allowing you to access high-resolution clips when needed.
Customizing HD Preferences
To enable native-resolution streaming for motion-inclusive segments on the Timeline page, in the bottom right corner of the video player, click the HD button. To make HD the default, enable High Resolution Live Video Streaming under Settings > Personal.

Overview
Coram dynamically adjusts video streaming quality based on viewing context, balancing clarity with bandwidth usage. In single-camera views on the Timeline page, whether for live feeds or past recordings, Coram offers high-definition (HD) video that uses the camera’s native resolution. For multi-camera displays like Live View, Kiosk, and Personal Wall, streams default to standard definition (SD) to conserve bandwidth.
Changes in Streaming and Recording Quality Due to Motion
When a camera does not detect motion, Coram stores the recorded footage in SD quality. If motion is detected, both SD and HD footage is stored, allowing access to native-resolution footage when required, while still offering SD playback for faster load times and reduced bandwidth requirements.
Note: Different streaming protocols (HLS versus WebRTC) affect latency and quality. To learn more about latency , refer to Managing Video Streaming Latency.
Video Quality in Different Views
Live View, Kiosk, and Personal Wall
When watching multiple camera feeds, such as through the Live View, Kiosk, or Personal Wall pages, each video stream is shown in SD at approximately 512 kbps and 6 FPS. This helps maintain smooth playback and reduces bandwidth usage, especially when several video feeds are required to load simultaneously.
Timeline View
On a single camera’s Timeline view, you can switch to HD streaming for clearer, more detailed playback.
Tip: Enabling HD provides a clearer image, which is beneficial for reviewing important details or analyzing events precisely.
To activate native-resolution streaming, in the bottom right corner of the video player, click the HD button.
Note: HD quality is not available for portions of video that do not include motion.

Setting HD as the Default Quality
If you frequently use the Timeline page and prefer HD quality by default, you can enable this option in your personal settings:
Access the Coram web app and sign in to your account.
In the top-right corner of the page, click the dropdown arrow ( ▼ ), then select Settings.
In the Settings sub-menu, click Personal.
Enable the toggle for High Resolution Live Video Streaming.
Once enabled, any Timeline page you view will default to HD video, ensuring that you always get the highest quality image available without manually switching from SD.
