NOTE:

If you want to use "HTTPS Port", please enable the HTTPs settings on the configuration page of a web console with a Network Camera. Refer to the camera's User Manual for details.

The characteristics of each protocol are shown in the following table:

Protocol Description

 

UDP uses a simple transmission model without implicit hand-shaking dialogues for guaranteeing

 

reliability, ordering, or data integrity. Thus, UDP provides an unreliable service and data grams may

UDP

arrive out of order, appear duplicated, or go missing without notice. This protocol allows for almost

real-time audio and video streams. However, network packets may be lost due to network burst

 

 

traffic and images may be obscured. Activate UDP connection when occasions require time-sensitive

 

responses and video quality is less important.

 

TCP provides the service of exchanging data reliably directly between two network hosts, whereas IP

 

handles addressing and routing message across one or more networks. In particular, TCP provides

TCP

reliable, ordered delivery of a stream of bytes from a program on one computer to another program

on another computer. This protocol guarantees the delivery of streaming data and thus provides

 

 

better video quality. The downside with this protocol is that the real-time effect is worse than that with

 

UDP for a narrower bandwidth.

 

HTTP is a networking protocol for distributed, collaborative, hypermedia information systems. It’s the

HTTP

foundation of data communication for the World Wide Web. This protocol allows for the same quality

as TCP and the users need not open a specific port for streaming under some network environment.

 

 

Users inside a firewall can utilize this protocol to allow streaming data through.

HTTPS

This protocol enables authentication and encrypted communication over SSL (Secure Socket Layer),

which protects streaming data transmission over the Internet on higer security level.

ND4801 specifications

The Vivotek ND4801 is a next-generation network video recorder (NVR) designed for robust and efficient surveillance applications. With the rise of IP-based security systems, the ND4801 stands out as an advanced solution tailored for both small and large installations. One of its main features is the capability to support up to 64 channels of high-definition video recording, allowing for comprehensive monitoring across extensive environments.

Powered by Vivotek's cutting-edge technologies, the ND4801 employs H.265 video compression, which significantly reduces bandwidth usage and storage requirements without compromising video quality. This is particularly beneficial for users who need to store vast amounts of footage while maintaining clarity and detail. The recorder can accommodate various resolutions, including 4K Ultra HD, ensuring that even the most intricate details are captured effectively.

Another notable characteristic of the ND4801 is its user-friendly interface, which allows for easy configuration and management of connected cameras. The intuitive web interface provides real-time preview capabilities, playback, and advanced search functionalities, enabling users to efficiently navigate through recorded footage. Moreover, the NVR supports multiple display modes and layouts, facilitating seamless monitoring across multiple screens.

The device’s built-in RAID support further enhances data security, offering options for RAID 0, 1, 5, and 10 configurations. This ensures redundancy and data protection against potential drive failures, making it a reliable choice for mission-critical surveillance tasks. In addition, the ND4801 features PoE (Power over Ethernet) support, simplifying installation by allowing users to power cameras directly through the network cable, thus reducing cable clutter and installation costs.

To enhance surveillance capabilities, the ND4801 integrates sophisticated analytics features such as motion detection and people counting. These intelligent functions help in effectively managing alarms and can reduce false positives, leading to a more accurate monitoring experience. The ND4801 also supports integration with third-party VMS (Video Management Software), allowing for flexibility in system design and functionality.

In summary, the Vivotek ND4801 NVR is a powerful and versatile solution for modern surveillance needs. With its support for high-definition recording, advanced video compression, user-friendly interface, enhanced data security features, and intelligent analytics, the ND4801 is well-equipped to meet the demands of various industries, including retail, transportation, and critical infrastructure. Its robustness and adaptability make it an ideal choice for anyone seeking a reliable video surveillance solution.
