Dynamic calibration of surveillance devices

A system comprising:

• a data processing apparatus;
• and
• a non-transitory computer readable medium storing instructions executable by the data processing apparatus and thus upon such execute cause the data processing apparatus to perform operations comprising:
• receiving, from a camera, a set of images in which the camera detected a particular event based on a first set of camera settings;
• determining that false detections in the set of images made by the camera based on the first set of camera settings were caused by localized errors;
• in response to determining that the false detections in the set of images made by the camera were caused by localized errors, generating a second set of camera settings based on the localized errors;
• providing the second set of camera settings to the camera;
• receiving a sample set of images from the camera;
• detecting, based on the first set of camera settings, a number of false positives in the sample set of images;
• determining that the number of false positives based on the first set of camera settings in the sample set of images from the camera satisfies a camera setting reversion criteria;
• and
• in response to the determining the camera setting reversion criteria is satisfied:
• providing instructions to the camera that cause the camera to revert to the first set of camera settings.

At least one non-transitory computer-readable storage medium having stored thereon instructions which, when executed by at least one processor, cause performance of operations comprising:

• receiving, from a camera, a set of images in which the camera detected a particular event based on a first set of camera settings;
• determining that false detections in the set of images made by the camera based on the first set of camera settings were caused by localized errors;
• in response to determining that the false detections in the set of images made by the camera were caused by localized errors, generating a second set of camera settings based on the localized errors;
• providing the second set of camera settings to the camera;
• receiving a sample set of images from the camera;
• detecting, based on the first set of camera settings, a number of false positives in the sample set of images;
• determining that the number of false positives based on the first set of camera settings in the sample set of images from the camera satisfies a camera setting reversion criteria;
• and
• in response to the determining the camera setting reversion criteria is satisfied:
• providing, by the data processing apparatus, instructions to the camera that cause the camera to revert to the first set of camera settings.
