Abstract: A camera is configured with a multi-camera control engine that facilitates the creation and operation of a peer-to-peer camera network including the camera. The multi-camera control engine enables the camera to remotely broadcast its state information with other cameras in the camera network. The remaining cameras, upon receiving a broadcasted state, mimic the broadcasted state. In such a manner, the camera, via the multi-camera control engine, remotely controls other cameras in the camera network.

Abstract: Timing metadata is generated and added to captured video to compensate for synchronization error between video captured concurrently from multiple cameras. A wireless beacon including timer data is transmitted from an access point to each station camera. A radio circuit of the station camera synchronizes to the timer of the access point based on timing information in the wireless beacon. An image processor in each station camera includes an image processor timer separate from the radio circuit timer. During video capture, timing metrics are generated indicating deviation between the image processor timer and the radio circuit timer. The timing metrics are stored as metadata and can be used to compensate for synchronization error in post-processing.

Abstract: Disclosed is a system and method for securely storing a Wi-Fi password or similar WLAN security credentials on a device, such as a camera. The password is secured by encryption using an encryption key generated from the Service Set Identifier (SSID) of the network. A one-way-hash of the SSID is stored in a non-volatile memory of the device, but the plaintext SSID is not stored on the device. At a later time, the device may detect the SSID of the network and hash the detected SSID. If the hash matches a previously stored hash, an encryption key is generated from the SSID and the encryption key is used to decrypt the password associated with the matching hash. Without knowledge of the SSID, an attacker who gains access to the device will not be able to recover the password from the hashed SSID and the encrypted password.
