The problem might not be the android app you are using, but your bandwidth. I use iVMS-4500 and gDMSS on a Nexus 4, and iVMS-4500 HD and gDMSS HD on a Nexus 10, and I can stream perfectly main stream from all Hikvision and Dahua devices (1920x1080 is not a problem).

I'd tell you to forget about HDSDI. Go for HDCVI.

Is your camera the same as the onc pictured? Because that camera doesn't seem to have any infrared at all.

Your laptop has a VGA output; not input. You can not connect a DVR to a laptop with a VGA cable.

Install a better camera. Install the camera on a better spot. Install a camera suited for capturing license plates. Install a camera with better resolution (IP megapixel, etc). You will not get a license plate from that screenshot.

Never heard of 2CD3132, and it is not on Hikvision.com english site. That might just be the local model of the 2CD2132 (with some products Hikvision has a different model for the export product, and the local market product). http://www.hikvision.com/europe/products_show.asp?id=9638 http://www1.hikvision.com/cn/prgs_203_i1409.html

Have you actually checked them LIVE at 4 in the morning? Have you seen the live video, and made sure there is video at 4am? Not the recordings, but live video. Do you actually see video on all cameras at that time?

Do the cameras actually work at night? Check the live play on that time frame to see if they are geting any video. Maybe at night when the IR kicks in there is not enough power for all the cameras to work, and they are just showing a NO VIDEO until there is light again.

I have a Hikvision DS-7716NI-ST and a D-Link DES-1210-28P. The NVR does up to 16ch 5mbps. The switch has 24 ports 100mbps with POE (for cameras), and 4 ports 1gbps (one for the NVR, another one for connecting to my main network). I do not recommend NVR with integrated switch/POE, but that's up to one's personal liking.

Yes, iVMS-4500 does have bidirectional audio.

7208HWISH is a DVR, not a NVR. So it works with analog cameras and microphones, not with IP cameras. That means, the audio is not in "the camera location"; the audio will be wherever you install the microphone, and the speakers (which might be near a camera, or anywhere else).

Try with both analog BNC output and VGA output. Also, turn on the DVR with the mouse connected and the monitors ON. If you do not get mouse cursor, disconnect and connect again the mouse. I have had some customers with that same problem. I have no clue on what monitor they use, but the problem has always been on the customers side, when they bring the DVR to test here it always works great in our set ups.

Agree, I am quite sure the IR are not turned on. Check it on the config, or just walk to the camera at night to see if you see the IR leds glowing red.

Agree.

Short answer; no, you can't. Long answer; you can, but it might not be worth the hassle. You should contact the DVR manufacturer and ask them. I would first contact whoever sold you the unit, if possible. "h.264" is not a brand, but a compression algorithm, so "dvr h.264" is just a generic chinese dvr. It might be quite difficult to get a firmware update, if you can do it at all. Post a picture of the front and back of your unit, maybe someone will recognise it and help you out.

In camera motion detection: Camera tells the NVR "hey, there are things moving now, record!" NVR motion detection: Camera just sends video feed to the NVR all the time. NVR analyzes the video stream to see if there is any motion, and if so, it records (or does whatever it is told to do). Since the NVR is the one analyzing the video all the time, it needs/uses more CPU power on the computer.

That would look like crap, but it could work. But I am quite sure your analog to IP adapter only allows to configure one set of PTZ data, so you probably would not be able to send commands to two different addresses. So when you want to move the PTZ scanner, you would have to edit the config, change the address, go back to live view,... Doesn't look that useful.

Use a port other than 80 for web access to your DVR.

Those two cameras are Hikvision and Dahua. You shouldn't have any problem geting both of them to work with Milestone.

They are the same. If you want invisible IR you should look for 900nm IR. I am quite sure that 99.9% of normal cameras do not carry them. But these cameras also are not for hiding. You could forget about the IR of the camera, and get the IR somewhere else (900nm).

Yes, they are.

Of course you can, like you can do so with any other camera. Removing the case and IR would help a lot if you want to make the camera smaller.

Any IPC from Dahua that has audio will work.

He will just need an external power supply (which I thought he needed anyway; I do not know if the alarm outputs on the camera provide any power at all). Most of the Hik cams just come with plain wires (whatever the reason, it would not cost them that much to put one of those IO blocks). I will try to snap a picture later.
