So, what DVR card do you have? Ara you aware that not all cards work with all softwares, and not all softwares work with all cards? Many cards will only work with the software that comes with it.

Any IP camera will do that by using a dynamic DNS; you do not need a static IP. http://en.wikipedia.org/wiki/Dynamic_DNS

Never had an issue. You can connect a laptop directly to an IP camera, DVR, NVR, etc. the same way you would connect it to a switch/hub/router. Many years ago sometimes you had to use a crossed network cable (pins 1-2 3-6 connected to 3-6 1-2). I think nowadays everything is auto sensing, and they will work with a normal cable.

I have been there too... MD sucked on a Dahua IP system I set up. Either I missed too many events, or recorded almost 24/7. I end up configuring scheduled recording during business hours. I also remember testing Dahua NVR with a couple ONVIF IP cameras, and while they were recognised ok, MD was not working at all. So only manual, alarm or scheduled recording was possible. It has been a while, first thing I would do now was to check for the latest firmwares for both NVR and cameras.

While all of us here will know that they did steal the "patinete" (I don't even know how to say that in english, it was a scooter?), the footage would not be good for much with the police. As ssnapier said, they could just say that earlier that day they had left it by your house because some other kid was chasing them, whatever. You do not have any footage of them stealing anything, so they could make up any history that fits what is recorded. Also; the footage won't be of much use the the cops if they do not know who are the ones recorded. Do not expect them to have a database of faces that will give them their names and addresses. If you did know who those kids were, of course it would be more than enough to go have a talk with their parents, so you could hopefully get the scooter back, and have them get reprimended.

This one will work. You could also try using the 2.2A power supply for one camera, and the 3A for the other camera. But 3A should be more than enough for powering both cameras.

You will need another power supply. The one you have now is OK during the day when the IRs are off, but it doesn't supply enough A to make the cameras work at night when the leds turn on.

If puting the DVR on the DMZ works, then that means previously you did not have all the open ports needed. Puting it on the DMZ was just to check if it was (or was not) a problem of port forwarding; and it was. You can leave it on the DMZ, or find what ports you actually need, and forward only those ports.

That is all you have? No video from inside the garage where you can see them clearly? No video of them stealing anything?

Try puting your DVR as the DMZ host, so all connections are forwarded to it.

Hikvision sells this camera with 4mm, 6mm or 12mm lens. So yes, it is possible.

I think so. I say you can. I use the following baluns which use one pair for video, two pairs for power, and the extra pair for either audio or PTZ (it has screw connector). http://www.securame.com/transceptor-pasivo-de-video-alimentacion-audio-ptz-por-par-trenzado-dvt7001-par-p-124.html You really do want to go on the cheap, but yes, you can. Cat6 cable is thicker, and better quality. But with 35m you shouldn't have a problem with Cat5e.

Try connecting another video source on the video input; try connecting the camera on another one of the video inputs. If the problem persists, I would just send the unit back for replacement.

Many DVRs/NVRs can be recorded offline; the problem is at what cost. You will need a stable and very good internet connection to be able to do so smoothly. Let's go big (megapixel), like if I have 4 IP cameras 1920x1080@25fps. Each stream might be about 8mbps, that means I would need an internet connection capable of transmiting at least 32mbps. I would also need somewhere else another connection that can receive with no problem 32mbps, and a computer, NVR, NAS, etc. that will store the recordings there. If what worries you is a break in, it is usually way cheaper to install two DVRs. One in plain view (cheaper DVR, old DVR, non working DVR, whatever) and the real unit hidden somewhere. Once a thief finds the fake one, they will not bother looking for another unit.

That is an IP camera, not an analog camera. So no, it can't control a zoom lens, it doesn't even have RS485 input. It does have digital zoom. Why do you ned zoom? With 5mpx you do not have enough? Where do you want to zoom? And you want zoom without movement? (that is, you want to make zoom on the center of the image)

How about contacting Amovision support?

When you "enhance" the image on your phone with iVMS-4500 you are switching from substream to main stream. If the video feed becomes laggy, that means your main stream recording resolution is higher than your internet upload bandwidth. If your main stream is 1024kbps and your substream is 128kbps, watching the lower quality will be fine. Maybe you can even watch 4 cameras at the same time (128x4=512kbps) and it wil be smooth. But if you change to the main stream, you will start droping frames. In short, you need to know your upload bandwidth in order to correctly configure how you watch from outside.

Not really. What is that camera? A camera accepting RS485 controller doesn't mean that the camera can control external lenses, most likely that RS485 input is for the OSD menu. You can, but you will also need a software on your computer that is able to send commands to the camera.

Hikvision works quite well with Mac. You have iVMS-4200 for Mac, and you have iVMS-4500 for iPhone and iPad. You do have bidirectional audio with DVRs/NVRs, and also with IP cameras that have speaker/line out and microphone/line in.

Subscribing. I am interested on this feature too, I have msyelf a 2CD2032-I siting next to another huge analog camera, and the IR from both is just a bit too much.

Your blacks go pink? You need a lens with IR filter, so it will not let any IR light pass, since the HDB3200C does not have any IR or IR cut filter.

swastik, That is a common problem. The DVR does not check constantly for their public IP, so it might take a while before it updates the dyndns domain after the public IP has changed. Whenever possible, you should install the dyndns client on the router, which will notice right away when the public IP has changed, and so it will update the dyndns domain. With DVRs, it really depends on the brand. Some might check every x minutes (one hour maybe), but I remember old models that only checked at boot up; that meant that if the public IP changed, the dyndns domain would only get updated after reseting the DVR.

Just to name one problem you will bump into; lower resolutions (substreams) will be different on PAL and NTSC versions. D1 in PAL is 704x576 at 25fps, D1 in NTSC is 704x480 at 30fps. CIF in PAL is 352x288 at 25f0s, CIF in NTSC is 352x240 at 30fps. I think with Dahua you can not change from PAL to NTSC (or from NTSC to PAL) with just a firmware update, so if you buy some gear, make sure you get all PAL, or all NTSC. If you mix them up you might run into trouble (I would not want to configure a NTSC NVR with PAL IP cameras).

Modern DVRs work with SATA interface; they do not care if you use a 3.5" HD, a 2.5" HD, or a 2.5" SSD, as long as it is SATA. I think any SSD should do, just keep in mind that SSDs are not a good idea for recording on a DVR continuous (24/7) since they have a limited number of read/writes on them, but I think that is not the case. I like Hikvisions software and web interface way better than Dahua's, searching/browsing/downloading videos seems better to me.

Modulators are for converting a video signal into a Tv channel; if you would need one for each neighbour, that would be expensive. Will there be signal loss? Yes, if you connect from the DVR direct to 12 TVs with those cable length. You will surely need distributors and maybe amplifiers.
