Yes. Our NVRs support the Axis, Panasonic, and OnVIF network protocols for other brands' network cameras. So if your camera has one of the protocols mentioned above, it can be used with our NVRs though the performance is not as good as the DirectIP cameras. Of course, our non-DirectIP network cameras can connect with our NVRs.

There are two types of NVR: Standalone NVR and PC-based NVR. The Standalone NVR is mostly built on Linux OS (Operating System) based system designed for embedded processors, while the PC-based NVR is mainly MS Windows OS based system designed for PC platforms with dedicated boards for video surveillance.
 
* Benefits of a Standalone NVR
 - Usually less expensive
 - Takes less physical space (easy to hide in a safe place)
 - Safer from malware and viruses
 - Quiet in operation
 - Lower power consumption

* Benefits of a PC-based NVR
 - Gives better features such as video analysis, high-quality user interface, etc.
 - Able to have thousands of user accounts
 - More expandable hardware and software components
 - Easily maintain, change or upgrade hardware and software components

A network throughput in the NVR means local and remote multimedia data transmission rates of the network port in the NVR. For example, if maximum network throughput for local multimedia data recording and monitoring are 200Mbps and 50Mbps, respectively, and maximum network throughput for remote multimedia data transmission is 10Mbps, then maximum network throughput of the NVR is 260Mbps, which is calculated as the sum of local and remote multimedia data throughput. Using a network throughput, the total number of IP cameras connected to an NVR can be determined for real-time video monitoring and recording. That is, network throughput is important information to design and construct the NVR based network surveillance system.

No. Currently, eSATA ports in NVR do not support hot swapping. So, you should connect eSATA storage to NVR before NVR is powered up. Otherwise, NVR does not recognize eSATA storage. On the other hand, if  eSATA storage is swapped out while NVR is working, NVR can detect that situation and record data to another HDD.

Yes. NVR can retrieve and display the recoded audio/video data in HDD carried from another NVR.
However, NVR classifies another NVR’s HDD to the ‘other HDD’ type and does not support data recording until the HDD is formatted. That is, if you want to record data to the HDD carried from another NVR, you should back up the HDD's data to an alternative storage device if needed, then format the HDD.

To communicate with ATM/POS machine, NVRs have various hardware ports such as RS232C, USB, and RJ45 Ethernet port, and some NVRs have RS485 port additionally.
About data protocols, NVR supports Epson, VistaATM, XApCom232, XApComIP protocols. Also, at generic text mode, users can set the transaction start/end text and line delimiter by user-defined characters. You can select the hardware port and protocols on the NVR’s setup menu. For further detail, please refer to the ‘Text-In’ configuration in each NVR’s manual.

Yes. you can use conventional analog cameras with the NVR by adding network video encoders.
The network video encoder such as DE-1101 converts an analog video signal to a network video signal and supports the DirectIP protocol.
If you use the network video encoder supporting DirectIP protocol, analog cameras can communicate with NVR by DirectIP protocol.

Currently, G.711 u-Law, G.711 a-Law, ADPCM 16KHz, or G.726 audio codecs have been applied to the recorder. Please refer to the A&E specification for audio codec information applied in each product.

Most NVRs have RJ-45 female connectors on the back. You need to connect UTP cable’s RJ-45 male connector to NVR’s RJ-45 female connector directly. Also, you have to connect the cables correctly according to WAN or LAN. For WAN, you should connect the UTP cable to the public area network port. For LAN, you should connect the UTP cable to the local or private area network port. Mostly, CAT-5 UTP cable is used for connecting IP cameras, and CAT-5e or higher level UTP cable is used for connecting network switching hub.

A Network Video Recorder (NVR) is an internet protocol (IP) based video surveillance system or software that is designed to record and playback the video from IP cameras. Unlike DVRs (Digital Video Recorder), typically, NVRs do not have video compression engines on board because the video is digitized, processed and compressed by IP cameras, and then transmitted to the NVRs over IP network. But, the NVRs should decode both live video streams and playback video streams.

Usually, the NVRs support multi-channel video display, flexible recording schedule with different video profiles with playback capability, a user-friendly GUI, intelligent event detection and notification, remote monitoring and control, and PTZ camera control, etc.

There is a similar, but different network video recorders called Network Storage Recorders(NSRs). Typically, NSRs do not have video output, and all the operations are done over the IP network. So you need to use a PC to access the live or recorded video.
