Update to original post. I have just been ignoring the problem because I didn't want to deal with it but my picture has been getting worse. I recently updated my NVR to the latest firmware (2.3.7) and that didn't help a thing. Today I updated all the cameras to the newest firmware (5.1.2) and that did the trick. From what I can tell, when the WDR setting was turned on, the camera setting was somehow either doing like 0 or 100 but nothing in between. The NVR firmware update allows you to adjust all the camera settings and updating the cameras to the latest firmware got rid of all the noise I was having. Happy once again.

Hi, I am not sure what is going on. When I first installed the cameras, they all looked pretty clear at night. A few weeks ago, one of the cameras starting showing a real noisy picture at night. All the cameras are running the same settings so I am not sure why one would be doing this. I updated the camera to the latest firmware (5.1) and no dice. I also logged on to the camera and did a full reset and have powered it down, rebooted, etc. with no change. The cameras are running into a Hikvision NVR. I have included some screenshots below to illustrate the problem and to show my settings (look around the area not lit up by the IR and you can see the noise, during live video it is very noticable). Daytime shots look great. Any ideas what is going on and how to fix it? Thanks! Chad Current night time picture from camera.

Hi, You are going to need to get in to your router to redirect network traffic on port 80 to the NVR or pick some unused port and redirect that to port 80 on your internet network to the IP address of the NVR. Have you tried this yet? I only opened up ports 8000 and 5544 to get the smartphone app working. I use OpenVPN to get into my network if I need to get direct browser access to the NVR from my smartphone.

Do you have the substream option available? Without it, you may have issues getting any video appear in the smartphone app. I had that option disappear and had to do a couple of things to get it back. See this thread for more info-> http://www.cctvforum.com/viewtopic.php?f=19&t=38038

Yes, I am recording all 4 cameras at 3MP, 10 fps, 4096 Kpbs bitrate.

What about the Hikvision DS-9632NI-ST? It is a 32-channel NVR. http://www.hikvision.com/en/us/Products_show.asp?id=5575 I have the DS-7608NI-SE/8P with 4 cameras currently hooked up to it for a month now and I don't have any complaints but then I don't know better at this point either!

I had this problem as well and it drove me crazy for a few days. I tried all sorts of steps and finally did this: 1. Log on to the camera directly (not the NVR) and perform a full factory reset of the camera from the Maintenance menu. (I did this by plugging a laptop into one of the NVR ports) 2. Once the factory reset has completed, power down the camera (I did this by unplugging the network cable to the NVR as the NVR switch includes POE). 3. Waited 30 seconds and powered the camera back up (plugged the network cable back in). If I remember right, this brought back the substream option for my cameras. Hopefully this will work in your case as well.

Hi, I have a Netgear WNDR3700v1 power supply (12VDC, 2.5A) that works to power my Hikvision 3MP bullet and dome cameras but I have no idea what the barrel size of the plug is. I want to get a passive POE injector that I can use to power a camera standalone of the NVR and want to confirm the power supply barrel should be 5.5mm x 2.1mm or 3.5mm x 1.35mm since these appears to be common sizes for the passive POE Injector adapters. Or is it something else? Thanks Chad

I would like to thank everyone who has responded to this thread. All the responses have been extremely helpful!

Hi, I asked this question recently regarding a Hikvision NVR. Please see my thread regarding links on the forums here that may work for you plus a youtube video. http://www.cctvforum.com/viewtopic.php?f=15&t=37471

Here is the list of tested hard drive with that NVR. http://www.hikvision.com/en/support_more.asp?id=236 I bought a Seagate 5900rpm 3TB NAS HDD (Model ST3000VN00) for mine but am wondering about returning it for a 7200 rpm drive. I looked at the Seagate 7200rpm 3TB Video Surveillance HDD (Model ST3000VX000) but the reviews on Newegg were pretty abysmal with a high rate of the drives dying in the first couple of months of use. Thanks!

Hi, Thanks for your reply and the valuable info about telnet-ing into the NVR. I found this thread... http://www.cctvforum.com/viewtopic.php?f=19&t=35369&p=217655&hilit=telnet+nvr#p217655 ...regarding Dahua NVRs but I would expect the procedure to be the same as long as it is running some flavor of Linux. Thanks! Chad

Hi, I have a Hikvision camera setup (3mp bullets and dome) and a Hikvision NVR. After some preliminary testing, I found that I can't directly connect to the cameras that are connected to the NVR and the NVR doesn't allow me to tweak all the camera settings. After some thought, it seems like I can go two routes as I can still return the NVR. 1. Keep Hikvision NVR and buy a POE injector for when I need to connect directly to a camera, taking the camera out of the NVR environment for tweaking purposes and then reconnect when done. 2. Return the Hikvision NVR and buy a NAS and separate 8-port POE switch and have all the 3MP Hikvision cameras record to that. This would allow me to connect to any camera at will and the camera firmware appears to support this option. Problem is that I don't know how viable the NAS setup is. Can I record 8 streams of 3MP data to the NAS w/ a single drive at once and it will keep up? How do you go about making sure the content gets overwritten properly since you have independent cameras sending to the NAS? I was looking at the Synology DS213 NAS enclosure ($300) and then I'd need some combination of gigabit switches (at least for traffic volume to NAS?) to tie it all together for another ($250-300). So the difference in options is like $425 for the NVR and POE injector setup or $600 for the NAS and switch setup. I'd really appreciate hearing everyone's thoughts on this topic. Thanks! Chad

Hi, Thanks for the reply. Can I use any switch for this or must I use a POE switch since the cameras need POE? I have a spare TRENDnet 8-Port Unmanaged Gigabit GREENnet Standard Switch laying around but it is not POE. You are describing something like this? CAMERA -> SWITCH -> NVR BUILT IN POE SWITCH If I would need a separate POE switch, could I use a power injector to take each camera out of the NVR setup, do all the camera specific configurations and then hook it back to the NVR? The reason I ask this is that I am thinking that once I get the camera set up, I shouldn't need to get back into it's settings again or at least not very often. Buying a 8-port POE switch is expensive. Thanks, Chad

Hi, I am just beginning to play around with a Hikvision setup. I am running one of the 3mp Hikvision bullets connected to a Hikvision NVR. The NVR auto-detects the camera and I can connect to the NVR from my main home computer (on the same network) but I cannot connect via web browser to the camera that is plugged in to the NVR. It looks like I get a lot more camera setting adjustments if I can connect to the camera directly. I am running on a 192.168.1.x LAN IP block. The NVR configures itself when I check for it to use the router's DHCP server and assigns an IP address to the camera but I can't ping the camera IP address. Also, if I try to ping the IP address of where the camera is supposedly at I get "Destination host unreachable" Any ideas? UPDATE: I installed and ran the Hikvision SADP software and it only sees the NVR. Does this mean that the only way to connect directly to the cameras is to use a POE injector so I can power the camera outside of the NVR? If I did that, can I make all the camera specific adjustments and then hook it back into the NVR? Not elegant but it is doable I suppose. Thanks! Chad
