Service Processing Method and System and Device

A video surveillance system, comprising:

• a master camera;
• and
• multiple slave cameras,
• wherein the master camera and the slave cameras form a resource pool of the video surveillance system,
• wherein the master camera is configured to:
• receive a service processing request;
• determine resources required by a service requested by the service processing request;
• determine according to available resources of each slave camera in the resource pool, one or more of the slave cameras that satisfies the resources required by the service requested, wherein the available resources comprise at least one of a computation resource, a memory resource, a network bandwidth resource, an encoding resource, a decoding resource, an encryption resource, a decryption resource, or a storage resource;
• and
• assign the service to the one or more determined slave cameras for processing;
• and
• the determined one or more of the slave cameras are configured to:
• process the service assigned by the master camera.

A video surveillance system, comprising:

• a master camera;
• and
• multiple slave cameras,
• wherein the master camera and the slave cameras form a resource pool of the video surveillance system,
• wherein the master camera comprises:
• a first video capture circuit configured to capture video data;
• a first receiver configured to receive a service processing request;
• and
• a first processor coupled to the first video capture circuit and the first receiver and configured to:
• divide, the service into multiple sub-services;
• assign, the multiple sub-services to the multiple slave cameras, wherein each sub-service of the multiple sub-services is corresponding to one of the multiple slave cameras, the available resources of each slave camera of the multiple slave cameras is no less than resources required by a corresponding sub-service;
• and
• send the assigned multiple sub-services to corresponding slave cameras;
• wherein each of the multiple slave cameras comprises:
• a second video capture circuit configured to capture video data;
• a second receiver configured to receive the corresponding sub-service assigned by the master camera;
• a second processor coupled to the second video capture circuit and the second receiver and configured to process the corresponding sub-service.
