A method of failover recording of video streams in a camera connectable to a receiver device over a communication network, the method comprising: detecting that a bandwidth of a connection over the communication network is insufficient for transmitting a video stream at a predetermined bitrate, generating multiple parallel encoded video streams with different bitrates, storing the multiple parallel encoded video streams on a memory storage accessible to the camera, detecting that the memory storage usage of the memory storage exceeds a storage threshold, discontinuing the storing of one of the multiple encoded video streams being the encoded video stream that provides the highest bitrate among the multiple encoded video streams, and discarding the one of the multiple encoded video streams from the memory storage.

Video failover recording

A method of enabling a remote access to a first network device from a second network device includes the second device generating a data item signed by a network service trusted by the first device, and including a fingerprint of a public key of the second device. The signed data item is sent to the first device via a signalling service, SIGS, as part of a negotiation of terms for a peer-to-peer connection. The first device uses the received signed data item to verify that the terms it receives from the SIGS has not been tampered with by the SIGS, in order to prevent the SIGS from performing a Man-In-The-Middle attack. Various network devices and a network system are also provided.

A method for forming a combined image frame of a combined video stream comprises: capturing image frames of first and second video streams; encoding image data of the image frames of the first and second video streams, wherein each image frame of the first and second video streams are respectively encoded into first and second encoded data comprising a plurality of rows wherein each row has a height of a single coding unit and a width equal to a width of the image frame and is encoded as one or more slices; and combining the first and second encoded data into combined encoded data by interleaving rows of the first and second encoded data. The combined encoded data representing the combined image frame of the combined video stream.
