NVR (network hard drive video recorder) can be combined with routers, switches, IPC (network camera) and other devices to form a monitoring system, to achieve monitoring image browsing, video recording, playback, camera control and alarm functions. This article provides the specification parameters that may bring differentiated experience to NVR in practical applications. Please purchase according to your actual needs.
1Maximum number of access routes
The maximum number of connections refers to the maximum number of IPC connections supported by a single NVR. Generally, the last two digits of the NVR product model indicate the maximum number of access routes, for example:
TL-NVR5104: The maximum number of access channels is 4, and four IPC instances can be connected at the same time;
TL-NVR5216: The maximum number of access routes is 16. It supports simultaneous access of 16 IPC servers.
If the number of IPC is large, it can be combined with multiple NVR instances.

Maximum access bandwidth
The maximum access bandwidth refers to the maximum bandwidth data (such as 25 Mbps and 40 Mbps) that NVR can access. It must be greater than the sum of the streams of all connected IPC, that is:

Number of routes
The maximum access bandwidth of NVR also affects the number of access routes of IPC. Taking TL-NVR5108 as an example, its maximum number of access channels is 8, and the maximum access bandwidth is 40 Mbps, if the access to the IPC code stream is large (suppose 6 Mbps ), A maximum of six IPC connections (6 mbpsx6 <40 Mbps) are allowed ). If you need to connect eight IPC channels, you can adjust the IPC code stream to less than or equal to 5 Mbps.
Note:: The maximum access bandwidth of NVR of different models may be different. Take the actual model as the standard.

Maximum video resolution
The maximum video resolution is the maximum resolution that NVR supports access to IPC, such as 1920X1080 (1080 P, 2 million pixels ). The higher the resolution, the clearer the image.
4
Storage disk space and capacity
Storage disk space: Refers to the number of NVR hard disks (SATA interfaces) that can be connected. Generally, there are two types: single disk space and dual disk space.
Storage capacity: Refers to the storage capacity of a single hard disk, such as 4 TB and 6 TB.
The storage disk space and capacity directly affect the NVR storage cycle (that is, the recording time). The following figure shows the storage cycle of a 6 TB hard disk in different paths and resolutions:

, Supported?
PoE
Power supply
Some NVR products of our company support standard PoE power supply, and can provide IPC (such
TL-IPC313P) Power supply. IPC can directly connect to NVR without connecting to the PoE switch.
