Method and system for utilizing storage in network video recorders
View Patent ↗The subject matter discloses a method, comprising obtaining a current retention time of storage associated with a digital recorder; obtaining current bitrates of channels used to transmit video captured by edge devices communicating with the digital recorder. The method then determines change in compression rates to be allocated to at least a portion of the channels according to the current retention time and the current bitrates and transmits the change in compression rates to be allocated to the channels to edge devices communicating with the digital recorder. The method can be implemented in a system in which several digital recorders use the same storage.
1. A method for managing edge devices deployed in a site, comprising:
configuring the edge devices stream bit rate by a computerized component linked to the edge devices via a network;
receiving compressed streams from at least a portion of the edge devices;
measuring an actual bit rate of the compressed streams;
comparing the actual bit rate and a bit rate configured by the computerized component linked to the edge devices;
receiving parameters related to bit rate processing; and
according to the received parameters, adjusting by the computerized component via the network the bit rate of one of the edge-devices based on required bit rates of the edge devices, retention of the edge devices, bandwidth limitations of the network associated with edge devices, storage, viewing clients and performance limitations of computerized entities in the network.
2. The method according to claim 1 , wherein adjusting by the computerized component further comprises adjusting the edge devices dynamically according to constraints to locally record video thereon and to further transfer the data to an external storage device.
3. The method according to claim 1 , wherein adjusting by the computerized component further comprises setting a priority of at least one of the edge devices.
4. The method according to claim 1 , wherein adjusting by the computerized component further comprises setting, based on a schedule, the edge devices for optimized performance thereof in terms of bit rate and storage allocation.
5. The method according to claim 1 , wherein adjusting by the computerized component further comprises increasing the video quality of at least one of the edge devices.
6. The method according to claim 1 , wherein adjusting by the computerized component further comprises directing the video data of at least one of the edge devices to a reserved data device in case of a malfunctioning communication with a previously allocated data device.
7. The method according to claim 1 , wherein adjusting by the computerized component further comprises increasing bit rate of at least one of the edge devices on the expense of another edge device having its bit rate decreased by the computerized component.
8. The method according to claim 1 , wherein adjusting by the computerized component further comprises adjusting the edge devices dynamically according to time-related parameters measured statistically and historically.
