I have a "no-name" NVR that seems to have buggy firmware. Specifically trying to get it to communicate over the network.... I just cannot access it on the local network even though my router sees the IP address. Cannot ping the NVR, and any connection attempts time out. As an NVR, it works just fine but I would like to remote view it when traveling.

The model number is DJ-2516P ... no brand name on the box or device. However, looking at the model number, I have some no-name cameras which the model number starts with DJ. I have identified those cams as Dongjia cameras, so I'm taking a guess, this would be a Dongjia DJ-2516P 16 channel NVR

I don't see any boot screen, not sure how I would display that to see what OS this system is running. I'm guessing some flavor of linux. If that is the case, has anyone installed some more reliable IP cam NVR software on something like this?

Any ideas?

What IP address does it show / how do you know it's the NVR / how is the NVR connected to the network?

Beeeeecause I set a static IP address, netmask, gateway and DNS servers.... and can see the IP address in my router's status screen. The same with ticking the DHCP box for automatic settings- i see what DHCP has automatically set.. THENNNNN.... I see the MAC address in the NVR settings, and see the same MAC address on my router status next to the IP address I have set .... sooo, yeah, I know the router is seeing the NVR.

LOL, no attitude, just being a wizeass....

Oh, I also changed the HTTP port on the NVR ... I tried several ports... nothin worked. What I do notice, if the port is wrong, I get connection refused or something like that almost instantly, if I use the port number I have specified, when I try to connect to the NVR from my laptop on the same router/switch, the browser sits there spinning its wheels till it times out. I have no problem connecting to other devices on my local network via the ip : port.

If this NVR is running linux, I could probably flash Tiny Linux or some other micro sized kernel on the NVR then load some sort of linux based NVR program.... just an idea, seeing if anyone has Frankensteined a Dongjia NVR

Then again.... maybe I'll just get a Netgear 24 port 300W POE switch and build a mini ITX i5 in a shallow 2U rack case with a 10GB WD Purple drive, Ubuntu Linux and iSpy ,,,, eff trying to reuse this china stuff.... Too bad Blue Iris does not have a linux version... looks like that would work too but I'm not a WinDOHs person.

You could take all the guesswork out of hardware issues and use a laptop direct to the NVR so long as they are on the same subnet. Then try to ping it and or log on. If issues are still present, then I would guess firmware corruption, try doing a factory reset if you can find that in the NVR's interface.

Great lesson learned...just because something is made out of metal (this was very important to you in your other post) does not mean its quality....Wait till you connect those crappy dome cams and place them outdoors at night - that will be fun...
Yes, god forbid using windows....10 year old china firmware A-OK....:rolleyes:...
FYI, there are many alterative linux options other than ispy...

I actually have one of the "crappy dome cameras" outside , along with one of each type of bullet cam and an LPR cam .... Big improvement over the Zmodo outdoor cams I have installed. SO the cameras are not the issue.... Made of metal... what can I say ... I'm old skool... back from when cars were made of steel and didn't dent when the wind blows, when stereo instructions were in broken japanenglish, oh, and back in the day when lightbulbs could warm a can of soup and didn't flicker funkily.

And, yeap funky network issues in the NVR box. The LAN port will not establish a connection to the laptop in WinDOHs or linux, connecting to one of the IPC ports, connects but no communications, yet, the IP cams connect and operate just fine... hmmm.

I'll grab another NVR from the workshop tomorrow. Maybe these are just determined to be scrap metal. Luckily I only payed $150 for close to new 80 cameras and a bunch of new NVRs. I'm not complaining. LOL.

Post video from that camera as a human walks by......those were the nastiest dome cams on the market...rebranded by GW at the time...garbage...
Do you understand that cars are designed to crumple to SAVE the passenger inside? Aint that something...https://www.youtube.com/watch?v=fPF4fBGNK0U
All lights flicker - including incandescent. You cannot perceive the flicker on a modern led. Perhaps you have a bunch of old CFL's. Its unfortunate that you have not experienced a modern led. Only a complete idiot would waste 10 times the power to use an incandescent.

Get an led bulb in the 5,500-6,500k (daylight to cool white) range with a high cri and you're good to go. Avoid very cool ones as they give blue light (luckily never come across one domestically above 6500k), and avoid traditional yellow bulbs 2,000-3,500k as they produce a yellow colour cast. Personally, I think even 4500k (sometimes claimed as daylight) can be yellow - daylight claims vary ebtween 4500-6500k, but 5,500-6500k is where it's at in my opinion). I've never had an issue with 5,500-6,500k.

On the efficienct side, an 8w led will give the light output of around 60-100w of incadescenent. Most bulbs claim 60w but in my experience, it looks nearer to 100w. The next step up to around 12w will get a 100w rated bulb.

All that said, with good cameras such as the 4kt, you don't need more than 5w led to get a good full colour but slightly dark picture at night using a 1/250th shutter (4ms), low gain (50 max) and can re-inforce that with a sensor flood to get a much brighter picture if someone comes into the frame to raise it to daylight quality. An alternative is the 5442, the latest of which have good night vision in colour, albeit not 4kt standards, and good B&W ir for zero light. 5442 is the go to camera for many with a good compromise between night vision and depth of field.

Overall, Read the wiki for advice as it's full of recommendations and will save you expensive mistakes from no brand equipment, poorer quality equipment and Chinese language hacked cameras....
