Network surveillance video recording system and network video recording backup machine

Abstract

A network surveillance recording system includes a network camera, a network recording host, and a network recording backup unit. The network camera is used to output streaming video. The network recording host is connected to the network camera and includes a first storage module, a first network module, and a first processing module. The network recording backup unit is connected to the network recording host and the network camera. In response to an anomaly in the network recording host, the network recording backup unit starts and takes over the recording task. The network recording backup unit includes a second storage module, a temporary memory module, a second network module, and a second processing module.

Claims

1. A network surveillance recording system, comprising: a network camera for outputting a streaming video; a network recording host connected to the network camera and comprising: a first storage module; a first network module for receiving the streaming video from the network camera; and a first processing module electrically connected to the first storage module and the first network module for storing the received streaming video in the first storage module to form a first long-term video data, and routinely backing up and transmitting the first long-term video data via the first network module; and a network recording backup unit connected to the network recording host and the network camera, wherein in response to an anomaly in the network recording host, the network recording backup unit initiates a takeover recording task, the network recording backup unit comprising: a second storage module; and a temporary storage module; A second network module is used to receive the first long-term video data from the network recording host and the streaming video from the network camera; and a second processing module is electrically connected to the second storage module, the temporary storage memory module and the second network module, used to back up and store the first long-term video data to the second storage module, and to temporarily store the streaming video to the temporary storage memory module in a rolling manner, so that the temporary storage memory module stores the latest segment of the streaming video, wherein when the recording task is started, the second processing module stores the latest segment and the subsequent streaming video as a second long-term video data and stores it in the second storage module.

2. The network surveillance and recording system as described in claim 1, wherein, The first storage module is configured as a Redundant Array of Independent Disks (RAID) architecture.

3. The network surveillance recording system as described in claim 1 further includes a network switch for establishing a local area network environment for connecting the network camera, the network recording host and the network recording backup machine.

4. The network surveillance and recording system as described in claim 1, wherein, The first network module of the network recording host periodically sends a heartbeat signal to the network recording backup machine. When the second processing module of the network recording backup machine detects that the heartbeat signal is interrupted, it starts the takeover recording task.

5. The network surveillance and recording system as described in claim 4, wherein, When the second processing module of the network video backup machine detects the recovery of the heartbeat signal, it terminates the takeover recording task and transmits the second long-term video data to the network video host via the second network module.

6. The network surveillance recording system as described in claim 1 further includes a mobile device connected to the network recording backup machine, wherein when the network recording host malfunctions, the network recording backup machine sends an abnormality signal to the mobile device.

7. The network surveillance recording system as described in claim 1 further includes a management center host connected to the network recording backup host, wherein when the network recording host malfunctions, the network recording backup host sends an abnormal signal to the management center host.

8. The network surveillance recording system as described in claim 1 further includes an uninterruptible power supply device electrically connected to the network recording backup unit.

9. A network video recording backup device, comprising: a storage module; a temporary storage module; a network module for receiving a first long-term video data normally backed up and transmitted by a network video recording host, and receiving a streaming video from a network camera; and a processing module electrically connected to the storage module, the temporary storage module, and the network module, for backing up and storing the first long-term video data in the storage module, and temporarily storing the streaming video in the temporary storage module, so that the temporary storage module stores a latest segment of the streaming video, wherein when a recording task is taken over, the processing module aligns and connects the latest segment with the received streaming video to form a second long-term video data stored in the storage module.

10. The network recording backup device as described in claim 9, wherein the storage module is configured as a disk array architecture.

11. The network recording backup unit as described in claim 9, wherein the network module receives a heartbeat signal periodically sent by the network recording host, and the processing module initiates the takeover recording task when it detects that the heartbeat signal is interrupted.

12. The network recording backup machine as described in claim 11, wherein the processing module terminates the takeover recording task when it detects that the heartbeat signal has been restored, and transmits the second long-term video data to the network recording host via the network module.
