This is XM(XiongMai DVR) also known as Jufeng. http://www.xiongmaitech.com http://www.jufenginfo.com/

If you show the GUI and also name of mobile software, will be more easy to identify the brand. Mainboard and dvr case very difficult to tell.

From the snapshot the Http & Telnet is not enable over WAN. So if your are really afraid, change the http port to other than 80 & create a very secure password to login.

Did you try this? Solution: Disable WAN-side HTTP and Telnet access. It is not possible to change the default web administrator's password for the user admin. http://www.websec.ca/advisories/view/Huawei-web-backdoor-and-remote-access

Have you try VLC to open the file?

What is the name of the remote app use in this NVR?

You can use most 3g/4g dongle but most telco have 2 ip, 1 is the WAN IP that you can see and another public IP that is normally share. Only way to view if the telco in your country follow this norm is to use the P2P setting built-in on Dahua newer NVR.

Full copper Cat5e? Did you try to remove the other 2 camera in the 1 cat5e 3 camera run and see if a single camera will be better?

What type of cable and how do you power the camera?

I do not agree with you on the bolded part though. Nowadays most decent manufacturer's Infra Red is very well tuned for total darkeness, there is no reason to go for a black & white camera. And if not total darkness, you can in fact have nice color even at night with the new Starlight CMOS from Sony.

Did you start to sell EX-SDI? Your opinion just curios Yes just some to an existing customer but I have already given up on SDI completely even though picture quality wise is still the best until 3-5Mp HD Analog is out in full productions with the corresponding spec DVR.

Mine is from China and it is quite reliable. In fact currently many suppliers are clearing their SDI peripherals as many Chinese factories has ceased to produce SDI camera & DVR.

I think if you still can get SDI DVR it is a better solution, I have done a few installation for Clubs using SDI Speed dome and one of the bigger one in fact using all SDI camera for their surveillance.

Hi. Please do not buy a dvr with monitor built in .. What is your budget for a dvr I am welling to spend up to $300 i think for just the DVR I already have a 3TB HD in stock. I did read some of the other posts it seems TVL does not matter when it comes to analog since it is limited to NTSC. Sucks I will have to pull all new wires to get digital. Most of the HD CCTV System have option to set PAL/NTSC for the DVR & Camera so this is no longer an issue with HD analog. Only traditional SD Analog have this problem.

Even 2Mp TVI recorded at 25/30fps also cannot capture moving vehicle licence plate at night. You will need 50/60fps but am not aware of any HD Analog camera/DVR combination having this feature for 1080p. You can see the difference in my youtube upload below. tGD84NatAfQ gYNGx1A6p2M

Seems like a good idea but need to test out with some video footage to see how reliable this is.

Have you try "call preset 95" If the OSD menu comes out just navigate to Factory reset.

Use a passive POE extender, can extend another 100-120M or more if use multiple units.

Since I snap using a mobile, you won't see much difference but if you view live & compare, you will see a huge difference.

Here is the comparison between HDMI & AV output on a TVI DVR. Even though it is from 2 different DVR the end results will be much or less the same.

Any link for this single coax to 8 CVI/TVI? TIA

1. If you use HDMI to AV converter you can sent the video to all the 4 TV, quality is still decent. (better than analog) Another option will be using HDMI cat5e transmit/receive but you will need to run new cabling. (best quality)

If you need good quality SDI, I can point you to the biggest and most probably only one left in Shenzhen still doing R&D with SDI camera. FYI, most manufacturer in China has already given up on this format!

Your 1080P TVI for $35 uses what CMOS Sensor? Am testing one with Sony IMX322 & another with Aptina AR0230 and was suprised the AR performs better in low light and the 322 only have a slight edge on image resolution.
