1. What is a Network Video Recorder (NVR)?


The Network Video Recorder (NVR) is a complete IP Camera recording device. It is similar to the Video Server system, but instead of using a standard Windows computer, it uses a dedicated special computer with an operating system and application software that is dedicated to recording the video. It also allows many people to view real time and recorded video. The term evolved from the older DVR (or Digital Video Recorder). The NVR includes both the computer and special Video Management Software (VMS). The computer usually uses Linux, but there are some that use Windows as well.


For a comparison of the Computer Server using VMS and the Network Video Server (NVR), take a look at our review and comparison of various systems.



2. How do I update the firmware on my DVR/NVR?

You will be required to update your DVR or NVR to the latest available firmware upon system start-up. This is required to enable remote viewing of your system (you will also need to upgrade your client software or mobile apps). 


When notified after start-up, you will be prompted to upgrade the firmware. Click OK, and enter your system user name and password. The system will then restart once the upgrade has been installed. After this initial set-up, firmware upgrades will automatically be installed as long as your DVR or NVR is connected to the internet.



3. How many cameras can I connect to my DVR / NVR?

The amount of cameras you can connect to your DVR or NVR depends on the number of available channels. A 16 channel DVR can connect up to 16 cameras, for example. DVR models typically come in 4, 8, and 16 channel models, while NVR's typically come in 8, 16, and 32 channel models.



4. How to reset all setting of the NVR system?

If you can login your NVR system, you can follow up the below steps to reset your NVR system:

Please go to NVR's System setup - System Admin - Factory setting to tick the setting you want to reset. 



5. What is the difference between NVR and DVR?

Digital Video Recorders (DVR) are analog while Network Video Recorders (NVR) are digital. 


For the most part, DVRs and NVRs provide you with the same functions, such as recording, motion detection, and remote connectivity. But are fundamental differences, as well. For instance, the way that security cameras are connected and how the recorders receive incoming video. 


DVRs, for example, receive footage from analog security cameras over RG59 siamese BNC cables. The DVR then encodes the footage (using H.264 Advanced Video Coding) and stores it to the hard drive. NVRs, on the other hand, receive footage that is already encoded and compressed by Digital IP security cameras over Cat5e Ethernet cables.



6. What if your NVR system keeps beeping?

1. Please right click your NVR mouse, then click System Setting - General Setting - Error setting, make sure that "Enable" and "Buzzer" are unchecked.


2. Please right click your NVR mouse, then click System setting - Channel setting - Video Detection, make sure that "Buzzer" is unchecked for all channels.


3. If you have checked above 2, and none of the buzzer are checked.

9. What type of connectors are used to connect DVRs to security cameras? 

All of our surveillance DVRs have female BNC connectors for camera inputs. Our security cameras have a female BNC connection. Our Video & Power cables have two male BNC ends which connect cameras to a DVR.



10. What type of monitor can be connected to a DVR? 

This depends on which DVR. There are three types of video outputs that vary by DVR model. The three types of video output connections are: BNC, S-Video, and VGA. 



11. What if I cannot get any display on TV from the NVR system?

This is caused by resolution compatibility issue. 
The default output resolution of the NVR is 1280*1024, which may not be compatible with some screens.



12. What is a Digital Video Recorder (DVR)?

The DVR is a device that records video from analog cameras to one or more hard drives. It is used in CCTV systems. The term DVR is also used by the consumer TV market. The DVR used in the security market has a fixed number of BNC connections to attach analog CCTV cameras. DVRs are available with 4, 8 16, 32 and 64 channels (or connections). This means that you have a maximum number of cameras that can be supported by one unit. Once you exceed the number of connections available on the DVR, you will need to add another DVR to your system. Some DVRs connect to the network and can be viewed using a Windows computer.
