NVR (Network Video Recorder)
A network video recorder is a dedicated computer that records video surveillance footage in digital format on a hard drive. NVRs do not have video recording capabilities, so video is typically processed and encoded by surveillance IP or CCTV cameras and sent to the NVR over an Ethernet or WiFi network for storage. NVRs are typically used in IP video surveillance systems. NVR systems record video from Internet Protocol (IP) cameras. Unlike analog cameras, IP cameras can reuse videotape data at the source. The processed video data is then sent to the NVR over an Ethernet cable or WiFi.
IP cameras typically offer much higher resolution than analog cameras. Network video recorder systems use IP cameras, which can process video data before transferring it to the recorder. IP cameras are usually more robust and can record and transmit audio in addition to images. Advanced hardware in IP cameras allows for intelligent video analytics, such as license plate and facial recognition. Network video recorders are considered complete IP camera recording systems and are primarily used in IP video surveillance systems. Network video recorders do not use dedicated hardware to capture video, but rather specialized software on a dedicated device.
Not only can they record video and audio, but they also allow you to access images and live scenarios on the recorder. Unlike traditional recording devices, NVRs do not have built-in video recording hardware. Instead, they use specialized software on a dedicated device to receive processed and encoded video from IP or CCTV cameras over an Ethernet or Wi-Fi network. In summary, NVRs are characterized by their network connectivity, flexibility, and efficiency, making them a good fit for modern video surveillance systems. NVRs still record data in digital format, but they do not process it, as this is already done by IP cameras.
Post Description:
A Network Video Recorder is a programmed computer device that supports CCTV IP Cameras and Records their Video Data in Digital format on a storage device like hard disk Drive, USB Flash Drive, or SD Memory card.
The program or Software that is also called the Firmware of the device may sometimes corrupt or be affected by bugs due to some reason that causes the NVR not to be functional. In this situation, we need to get back the device functional by loading its genuine software/firmware by the programming tool. So, Here is below the collection of some of NVR’s Firmware files for free download that may be very helpful for all.

Hello,
I have an Owsoo 4 channel model TW-7004NVR recorder with a Hi3520 (software version 1.0.1.4960, hardware version 1.0.0) chip. My current problem is the unit does not recognize the Hitachi Enterprise hard drive I installed, brand new. It will see the hard drive when I connect it via USB with an external case with the hard drive in it and I am able to format it. I connected this hard drive to my desktop computer and it sees it and it is formatted, put it back in NVR and still does’t see the drive. I have been back and forth with the supplier and they even said the hard drive should have been recognized. I tried to have them send me a link for a firmware upgrade to see if that would fix my problem, they just don’t understand. Would you have a firmware upgrade for this chip? Thank you in advance.
sorry upgrade not available. try Seagate Hard Drive
Thank you for the quick reply and information. I just got a WD green hard drive for security, see how that goes.
SIR DVR KA LOGO KAISE CHANGE KAISE .
no idea
Can i install it on my old MC NVR model MDW-NE04HF? it runs in syslinux 6.02 EDD now corrupted.
better to read firmware and write in new flash ic then check
Maybe firmwaer xvr-v400-8ch-v1.1
Hi,
got a shoddy NVR device back from a friend, it’s a local branding (PNI Romania) but the board is chinese as most if not all others out there. It’s been bought brand new from the store and he didn’t even mount a HDD in it. I mounted an 80GB drive in it for test purposes; it’s on second input not first, if it matters – physical issues with the cables.
Problem is, it doesn’t record anything on motion detection, the Region setting window doesn’t open for any channel, and the Encode window also doesn’t open – showing just a NoConfig messagebox. However, it does record manually, but this just defeats the purpose.
The firmware is 4.02.R11.34531119.12001. Here is a picture of the board inside; note the main chip has a cooler stuck on top so can’t say what model it is:

It would be great if there were a firmware update for this device, or some method to access the OS and try to fix whatever there may be broken.
I have not (yet) tried a reset from the menu because the setup was a pain, and it’d be annoying todo it again, but in the end I may resort to that to see if it fixes anything. Problem is, if the setup got borked so easily once it can happen again at any time, so maybe there’s an improved formware out there that fixes some of these issues.
Thank you for any recommendation!
Sorry, the update is not available. raise your queries in DVR/NVR related Forum
