A video camera recording system is provided. The aspects include one or more memories configured to store program code. The program code is for performing an automated verification test of elements of the video camera recording system using at least one artificial intelligence (AI) model to identify potential issues with the elements of the video camera recording system. The aspects further include one or more processors, operatively coupled to the one or more memories and configured to run the program code. The aspects also include a transceiver configured to transmit instructions causing a corrective action to be performed for at least one of the potential issues.

Embodiments include a system, method, and computer program product that enable secure access to cameras in smart buildings. Some embodiments control outbound video from an environment such as a local network through an intelligent on-event video pushing mechanism. The local intelligent on-event video pushing mechanism hides the IP address of a source video camera, transcodes the video to a reduced size for wide area distribution, and pushes video to a recipient upon an event triggered received within the local environment (e.g., the local network.) Embodiments enable a remote video client on the far-side of the local network firewall to view the video streams of cameras on the near-side of the local network firewall when an event or trigger occurs.

The present invention provides a testing system for a video and audio reproduction system, the testing system comprising a data source, comprising video and audio data for reproduction by the video and audio reproduction system, the video and audio data comprising unique marks in every video frame and every audio frame, a recording unit, configured to record a video stream and an audio stream generated by the video and audio reproduction system based on the video and audio data, and a test processor, configured to extract the unique marks from the recorded video stream and the recorded audio stream, and to verify if respective unique marks of simultaneous video frames and audio frames have been recorded by the recording unit simultaneously. Furthermore, the present invention provides a testing method, a computer program product, and a non-transitory computer readable data carrier.
