What is the role of a streaming media server?

In environments where numerous clients access web surveillance cameras simultaneously, standard recorders may be unable to manage the resulting network load effectively. To mitigate this issue, the implementation of a streaming media server is essential. This solution will alleviate the network pressure by efficiently routing client access requests to the server, ensuring optimal performance and reliability of the surveillance system.

Is a video recorder necessary when using a disk array?

The disk array provides robust storage capabilities for data management, necessitating the use of a dedicated storage server to oversee these functions. In general, the presence of a disk array negates the need for a traditional video recorder, streamlining the storage process and enhancing overall efficiency.

What is the difference between an integrated machine and a movement?

The movement is designed as an integrated unit without a protective housing, allowing it to function as part of a broader system. While the integrated machine can operate independently, the movement requires connection to the ball machine to function effectively. This connectivity is essential for optimal operation and performance.

How to solve the problem that the camera is not recognized when connected to the recorder?

1.Network Connectivity Issues

2.There may be discrepancies in the IP addresses of the camera and recorder, indicating they are not on the same network segment. Additionally, there could be incorrect configurations related to the port, username, or password, which may hinder proper connectivity and functionality.

What is the difference between a ball camera and a PTZ camera?

Dome cameras typically have limited elevation capabilities, offering either no elevation angle or a maximum of 20 degrees. In contrast, pan/tilt cameras provide significantly greater versatility, with the ability to achieve elevation angles of up to 90 degrees, enhancing their effectiveness in a variety of surveillance applications.

How to distinguish whether a network video recorder has CVBS (BNC) output?

The hardware interface located on the rear of the host is marked with a "CVBS OUT" label, signifying its support for BNC output functionality.

Why can't the network camera switch between day and night sometimes?

The inability of the camera to transition to black and white is typically attributed to insufficient low light conditions. Conversely, when ambient light levels are inadequate, the camera cannot switch from black and white to color. When ambient light reaches the threshold needed for the photoresistor to switch modes, frequent transitions may occur if illumination fluctuates around this critical value.

How to calculate the number of hybrid VCRs connected to the network and analog?

When determining the maximum number of cameras, there is no need to calculate the total number of connected analog cameras; the maximum is defined by the number of BNC input interfaces available on the recorder. For network cameras, the total number should be calculated by multiplying the number of cameras by the pixel height of each camera, ensuring that this total remains below the network access bandwidth of the recorder. Additionally, if one analog signal is deactivated, it creates an opportunity to add one network signal.

What does it mean when the NVR status prompts that resources are insufficient?

If the pixel bit rate of the IPC exceeds the maximum bandwidth capacity of the camera's decoding capabilities, it is advisable to adjust and reduce the camera's bit rate accordingly.

What should I do if the IPC is not online after being added?

1.The IP address of the IPC is not aligned with the NVR's network segment.

2.There may be network connectivity issues. Please verify that all eight cores of the network cable are properly connected.
