For just a little more $$ you can have DS-4216HFVI instead of DS-4216HCI. I say go for HFVI, which does 4CIF 25fps on each channel, instead of HCI, which is 2CIF 25fps each channel (half resolution of HFVI).

I am pretty sure they know already. I was warned the first time maybe on tuesday, by a customer that told me he had updated iVMS4500 on his iPhone the night before, and he had been unable to use the program since then. Hikvision pulled iVMS4500 from the app store soon after, so I am sure they broke something, and removed the program from the app store until they get it fixed.

Given that I am starting to support more and more Win7, I would like to find DVR cards that can be used with generic drivers and software. With WinXP, I had 3 models of cards with BT878 chip (one chip, four chips, 8 chips) which worked great with BTWinCap drivers, and then you could use any capture program you liked (even things like capture Adobe Premiere, videoconferencing with MSN Messenger or Skype, etc). I really have not tried too hard, but I think that so far there are no drivers for BT878 cards under Win7, at least I have been unable to get those same cards working. So I would like to find if there is any card/chip that, under Win7, will allow to use any program that makes use of Windows capture devices. Any hints?

Where did you get those numbers from? Not saying that they are wrong, I just would like to find an online lens/angle calculator I can trust. I usually use the following: http://www.sweeting.org/mark/lenses/cctv.php Which says that 1/3" with 2.8mm would be 81º; I do think that it is more closer to 129º than 81º, I would love to see an online tool like the one linked above that I can know for sure is accurate

rory, I think you need a Dahua subforum...

Seeing that the topic is solved, offtopic time! I think Dahua used to have the firmwares for download on their web site. I really think I had seen them... sometime in the past. Not any more, now the "Firmware" section on their web page just shows "The material is being gathered" I never bothered downloading any firmwares, since I was only interested on multilanguage (spanish) firmware. Now, I was contacted by my supplier about a week ago, they told me they finally had the spanish firmwares. Good for me! I asked if they could send them to me, and they said nope, e can't supply you the firmware, but we can upload any DVRs you need updated. Just plug them on your network, forward port 37777 TCP, give us the IP, and let us do the job. And they did, indeed. First thing I thought was "I hope this DVRs do not start upgrading the firmware until the whole file has been uploaded", but we didn't have any problems. I had to connect one by one all the DVRs we had in store with the old english firmwares, and they upgraded remotely all the firmwares.

I hardly use (myself) PC based DVRs, just for tests, seting up for customers, selling them, etc. I am more a "standalone" guy. I have just used Netvision trial; but if you buy the hardware for them, you get the software license included on the price.

Question, I have gotten 8 rolls of a combined cable, and they are not exactly the same as the RG59 cable I usually work with. On the pic, top, cable I have received with coaxial and 2 power; bottom, cable I use daily, with RG59 and 2 power. According to Wikipedia, RG59 has overall diameter of 6.1mm, dielectric 3.7mm and core 0.81mm. That is correct with the bottom cable on the picture, RG59 I usually have, which with my own measurements it gives me 6.2mm, 3.8mm and 0.9mm (no, I did not make the measurements with the ruler in the picture... ). http://en.wikipedia.org/wiki/Coaxial_cable According to Wikipedia, RG58 would be 5.0mm, 2.9mm and 0.9mm; but the cable on the picture (top) gives me about 4.7mm, 3.1mm and 0.5mm. The core is what bugs me, it is way smaller than what a RG58 should be, and my measurements are not THAT way off. Now the question; what kind of cable do you guys think this is? I have 800m I would like to do something with, but I am not sure it is a good idea. The crimp connectors I have are no good for this cable, but I have solder connectors I could use. I am not even sure if this is RG58 since the core seems way smaller than what it should be, so I do not know if I could find RG58 crimp connectors... And even then, I do not know if I should even TRY using this cable with CCTV. I would rather just throw it all away, than waste worktime laying the cable down, just to find out it is not good enough and that it needs to be replaced. Any suggestions?

Hi, I got 3 days ago a Dahua DH-DVR3204LE-U DVR (32ch), and it came with a deffective CD; I can see the contents on the CD, but I can not open the files. I am in need of geting the manual for this DVR quickly, and I have been waiting 2 days for an answer from my supplier with no luck. Does anyone know where to get the PDF manual for this model? I am unable to find it on Dahua's web site. If anyone can send me a ISO of the full CD that would be great (with yousendit.com or some web site like that it would be great). Thanks!

That was so lame from me... Now that I knew what I was looking for, I found it easily on Dahua's web site. I wonder why on each product page they put a "download" tab, and there is only the datasheet pdf in there. On the download section I had seen the LE-S/HE-T manuals, but I was looking for the LE-U series, which seems to be the same as the LE-S series, but with 8 SATA ports instead of just 4.

This one, right? Thanks! LE-S&HE-T Series DVR User's Manual V2.606 0911.pdf

http://www.hikvisionusa.com/downloads.html Tools section, "file player" is for playing the videos under Windows, "file convertor" is for exporting them to common formats so they can be played back directly from any video player like VLC. Noone from Hikvision should be expected to help you configure your router/open your ports, that has nothing to do with their product. It works with Activex, which is a technology for Internet Explorer. I am sure there are ways to make it work on Apple, never had to do it before. And you can also change any settings locally from the DVR, you just need a monitor and mouse. If you use exclusively Mac, maybe Hikvision wasn't the right choice of DVR, maybe you would have been better with Dahua, which has software for Mac.

If you use the camera wired, there are no interferences. You can connect any of the 4 cameras direct to a TV, and you will have a good image (a good, cheap, 380 lines CMOS image, that is). Connecting the camera wired will not stop the transmitter. They work at the same time wired, and wireless. You could wire them to a DVR somewhere in order to record them, and connect the receiver on a TV somewhere else on the house to view them; when viewing them, you would of course have worse image quality. It all depends on the quality you need, and what you want to do with the kit. You need to see the kids playing on the yard, who is ringing your doorbell? Might be enough. You want to be able to catch a thief who breaks on your house when away, and have any good shots of their face? I doubt it. The video you uploaded is wireless, not wired.

The fact that you can connect to your DVR from inside your network has nothing to do with connecting from outside. Inside your network you will connect to your lan IP, something like 192.168.1.x, you should be able to connect easily to it from any computer, or even from your iPhone if you are using your wifi; you MUST use the lan IP. From outside; you need to have the right ports forwarded to the DVR IP. And, of course, you must try to connect to it from outside the network, and connect to your wan IP, not the lan IP. If you do not know what is your IP: http://www.whatismyip.com/ For testing; it will be WAY easier to do it from a Windows computer then from your iPhone, I usually just connect remotely to my home computer, and from there try to connect to the DVR I am configuring.

All DVRs have PTZ controls, all DVR softwares have PTZ controls... That of course are only useful if you have PTZ cameras, and will do nothing with a camera that has no moving parts at all. Back on topic; as they have told you already, this kit is just a toy. 2.4G wireless (which anyone else can use/view, even your computer wifi could be causing interferences), maximum distance 100m with view from camera to receiver (which will never happen). The video you posted above does not show anything weird to me, it just shows me that you need to move the camera closer to the receiver.

Do you see anything on those cameras that make you think they are going to move? You want pan/tilt? Push the camera gently on any given direction. Want some zoom? Grab the camera and move it forward.

PTZ...!?!?

Some routers might give problems when using port 80, since that is the port used for accessing the router. Hikvision only use 2 ports, one for web and one for data (by default 80 and 8000), so I do not know why you are forwarding 3 ports (80, 90, 8000). I always change 80 to 90, so I leave it at 90 for web and 8000 for data. IVMS4500 on iPhone only uses the data port (8000), so 80/90 should not be the problem, it would work even if you do not have them open. Both ports need to be forwarded with TCP and UDP. You already stated it above so this should be correct, but it is important that the DVR has the gateway configured correctly (usually the gateway IP will be your router).

Source code for what exactly...?

I have 3 different models of BT878 cards that I use often under XP (with one chip, four chips, and eight chips). I know how to use BTWinCap with no problems under XP, I just was unable to get them to work under Win7 32bit the one time I tried, so I assumed that the drivers were so old, that it would not be possible to make them work under Win7. I guess I will have to give it another try...!

That's not so bad if you got them to work, I tried once and wasn't able to...

Ahhh, Conexant BT878 chips... For all I know, there's no drivers at all for Win7 for those

Check out VNC parameters. You can create a shortcut that will connect automatically to any of the computers, by passing the IP, port, and even password as a parameter to VNC.
