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.
7.How to reset the NVR--K9608-W system?
You can follow up the below steps to reset the NVR:
(1). Please format your USB-disk to FAT32
(2). You can directly download and save the file to your USB-disk from the attachment.
Please note: please directly save the file in the root directory of your USB-disk, not save it under any folders.
(3). Please insert the USB-disk to the NVR's USB ports
(4). Please connect the power supply to the NVR, once the NVR system starts, you will hear "beep" sound.
The system will reboot itself several minutes later, please be patient.
Please note: this file can only be used once, you need to re-save it to your USB-disk next time.

(1). Please format your USB-disk to FAT32
(2). You can directly download and save the file to your USB-disk from the attachment.
Please note: please directly save the file in the root directory of your USB-disk, not save it under any folders.
(3). Please insert the USB-disk to the NVR's USB ports
(4). Please connect the power supply to the NVR, once the NVR system starts, you will hear "beep" sound.
The system will reboot itself several minutes later, please be patient.
Please note: this file can only be used once, you need to re-save it to your USB-disk next time.
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.
13. How long can a dvr run before it needs to be reset?
A dvr can record for a few days to a few months depending on the size of hard drive and the sensitivity settings you select on the dvr. When a hard drive is full, the dvr will record over the oldest video automatically.
14. Which is better NVR or DVR?
A network video recorder (NVR) records IP cameras wirelessly (for WiFi NVR) or via Ethernet cables (for PoE NVR), while a digital video recorder (DVR) records analog cameras via coaxial cables. That's to say, the NVR is for IP cameras recording and the DVR is for analog or coax based cameras recording.
15. DVR vs. NVR System
Both systems record video data and are reliable. Although in the past the video quality of DVR systems lagged behind comparable NVR systems, today this gap is significantly lessened. The difference between DVR and NVR systems come down to the cost, how the data is transmitted, and type of cameras. NVR systems tend to have better picture quality, as well as easier installation, increased flexibility, and native support for audio on every camera that has a microphone. However, NVR systems also tend to be quite a bit more expensive than comparable DVR systems, which is an important consideration for the budget conscious consumer. For people looking for a relatively straightforward security system, a DVR system will most likely be sufficient, especially if your property is already wired for a coaxial cable from an existing security system. If you need a top of the line, very flexible solution, an NVR based system will be best. At the end of the day, the deciding factor will be based on the specific security needs of your property.
14. Do you need a DVR for security cameras?
Without DVRs or NVRs, IP cameras can still work independently as standalone surveillance devices, just like the security cameras with SD card. Better yet, you can also connect an IP camera to your phone, computer, laptop, TV without a DVR/NVR to stream live feed.
15. Can I connect my current Analogue cameras with your DVR’s?
Yes usually you can. The type of DVR you purchase has to match the type of Cameras you have.
Provided that your system is CCTV ready or capable and uses BNC style connections or Baluns it should work. Our DVRs work with most other CCTV equipment but we do not guarantee that it will work with every system.
16. What is a PoE NVR?
A Power over Ethernet (PoE) switch is a dedicated device that contains multiple Ethernet ports to provide power and network communications to IP cameras. This allows a PoE switch to expand the reach of an NVR system because you can connect IP cameras to the PoE switch rather than the NVR.
