MV Smart Cameras now offer smarter Motion-based retention with areas of interest and higher resolution snapshots using the API
Hot on the heels of the recent product release, we have two more features to share. These latest features are designed to give users more of what they want – more detail in snapshots, and more video retention by increasing the relevancy of motion-based retention. We’re doing this by enabling full sensor resolution snapshots via the API, and by adding regions-of-interest to the motion-based retention tool.
Full Sensor Resolution Snapshots
If you have used the Sensor Crop feature on MV12 series, MV22, or MV72 models, then you may already be aware that the cameras capture raw video at the full sensor resolution (4MP or 2688×1520) before downscaling the video to 1080p or 720p resolution for streaming and storage. Now, users can take “full-frame” snapshots using the Snapshot API. The resulting snapshot will have a 4MP resolution, regardless of the configured video quality settings.
The additional detail in the full resolution snapshot can be helpful for identification, or improving the accuracy of results returned by third-party computer vision services. It’s important to note that full frame snapshots are only available via the API on live video; snapshots on historical video are only available at the configured video recording quality. This feature is available on all second generation cameras running the MV 4.2 beta firmware.
Fine-Tune Motion Based Retention with Areas of Interest
Our next feature is designed to make Motion-based retention more intelligent. When Motion-based retention was first released in 2017, it offered users a way to dramatically increase the retention of video stored on the camera. With Motion-based retention enabled, the camera retains the most recent 72 hours of continuous video, after which time it trims footage that contains no motion. The original Motion-based retention eliminated the majority of “empty” footage for most users, but what about instances where the camera detects near constant motion in part of the frame, from a spinning ceiling fan or always-on displays? Adding regions of interest — an option already available for Motion Alerts — allows users to specify where they care about motion, say at an entrance or exit. Motion that occurs in other areas of the scene will be discarded for the purposes of Motion-based retention.
To add an area of interest, navigate to the camera, then settings, and quality and retention. Once Motion-based retention is enabled, click and drag on the video frame to select your desired regions of interest. Multiple areas can be selected to allow for fine-tuning. Once set, only footage that contains motion within the selected area of interest will be retained after 72 hours when Motion-based retention is enabled.
