the problem is you have port 80 set at both tcp and udp. should give your dvr a port away from 80. as far as the porn this will be down to him or his staff and the cookies restarting because of your tcp udp set for all traffic ------------- Tom- Thx 4 reply. AFAIK, port 80 was left alone. I had to solicit the router management company to forward the ports in the Cisco router. Since there had been an old Rapid Eye DVR there, which used ports in the 10000 range, I requested and got 3 10000 range ports all configgedfor TCP & UDP, since the DVR required I believe at least 1 port to be UDP and the others TCP. The router management tech said having all 3 ports configged for both UDP and TCP would not present a prob. Again, I am not a network or systems guru and so, at this moment am not aware of potential dangers imposed by this type of setup. AFAIK, port 80 is still set to TCP. AFAIK, the only ports configured also for UDP are the 3 10000 range ports I requested ported to the DVR. Could these be affecting the rest of the network? Can you please expound on: "as far as the porn this will be down to him or his staff and the cookies restarting because of your tcp udp set for all traffic"? Can you describe the process that would occur if the client or staff accessed a porn site and cookies were automatically downloaded? would they then possibly initiate connection to porn URL's automatically? Thx for info. Jeff

so.. what was the outcome here? Were you able to put the DVR online? I noted that the original poster had VGA signal that he originally wanted to put on the network. The AXIS product suggested is a composite video to IP converter. He would still have needed a scan converter to 1st convert the VGA to composite video (and the axis unit would need to handle PAL). Also, the DVR may have had a separate composite video output that could be configured to step thru all cams or provide a window grid.

Ah.. hardwired et al: thanks very much. Just b4 I read this latest post, I used canyouseeme.org to check port openings and every port I typed in showed up as blocked. Not wanting to type in a bunch of ports to find an open one, I used the 'DMZ' function on the Linksys router to forward ALL ports to the static IP I'd assigned to the server. ANd Voila! yippee! I was able to connect via IE using my unappended external router IP address as indicated by ipchicken.com hardwired: I just did the netstat -a thing, thanks, and I see all the info: various labels of 'listening', 'close_wait', 'time_wait' and 'established' which one's refer to open, available ports? what do those statuses mean? could all the 'established' one's refer to the myriad web connections I now have open? Thanks all.. I'm almost there. Woo-hoo! BTW the device is www.approtech.com/product_info.php?cPat ... cts_id=236 very cool product for my application

Greetings- I have been searching posts and am amazed at the tons of information. Thanks to all those that have posted. I'm just wanting some specific info. I have a small device about the size of a cigarette pack that contains an analog to digital video converter and web server. Theoretically I can connect to it remotely over web and view live video. After pinging network to make sure I didn't select an already active IP address, I assigned the device an IP address and subnet mask of the same 'group' or whatever its called: 192.168.1.xx and 255.255.255.0 It is working on the LAN, but I can't connect over web. I have tried forwarding various ports, e.g. 80, 8080, 3777 and used ipchicken to see the cable modem/router's outside IP address. Yes, I enabled the port forwarding in the router. There's a selection parameter in the router for TCP, UDP or both. What should that be set to? What does that effect? I initially set it to 'both'. From a remote PC in another state, using Internet Explorer, the following was entered, although I don't know if this is the correct format I should be using (the following is a made-up ip address): http://12.345.567.34:80, where 80 is the forwarded port. I tried 80, 8080, and 3777. Each time of course I configured the video server's port # to correspond. Is there something obvious that I'm doing wrong? I'm new to networking and would appreciate any info. Thanks Jeff

Ah.. thanks VERY much for the informative reply- this is the stuff I would like to understand in order to setup and troubleshoot connections. Yes I'm usinr cable modem/ router. I'm trying to connect to a single channel video server, which just converts 1 single analog cam. The server has an embedded web server (or is that a redundant statement?). I have the unit running now on my LAN- I connect with the server via Internet Explorer and the IP address I loaded into the unit. I see the image.. all is well... on the LAN. I haven't been able to log in with a remote PC via web and IE. I've tried several ports and port forwarding them: 80, 8080, 3777, 37777 I have used canyouseeme.org to check for blocked ports, and so far they all say 'error- I could not see your service on xxx.xxx.xxx.xxx. What does this mean? Are the ports actually blocked? How do I find an unblocked port? Obviously some ports must be unblocked somewhere! Any info is greatly appreciated. THanks

Hi. Am new to some of this stuff. Thanks for posting all these threads. Question: What is meant by the ISP blocking ports? and port 80 especially? Isn't port 80 the most commonly used port? if the ISP is blocking the port, how do you get through? Sorry for simple question. I am familiarizing myself with port forwarding etc. Thanks Jeff

Thanks for reply. A combo modem/ router is present at the client's/ video server site. Have you found that using a separate modem would allow connection where it couldn't occur via the combo router?

If your using port 80 you don't have to had the :80 to the ip address Thanks- I tried it with 80, 8080, 3777 and 37777 and entered separate trusted sites each time i changed port-forwarding configurations. Are you saying that for only the instance where the server is set to communicate on port 80 that I don't need to add it to the ip address? Am I correct then, to use the format of http://:?

Also, at remote PC, the http://12.345.567.34:80 address was listed as a trusted site.

Greetings: I'm hoping someone can hip me to a DVR with the following capabilities, or at least most of them. I've tried Hikvision and Intellicam and, while they are quality units that do a lot more things than the popularly marketed, familiar name units do, maybe I'm asking too much from a non-PC system? Reqs: 16 analog video ch/ no audio req'd Dual stream so net streams can be significantly smaller At least 5 PC's connecting via intranet and web and receiving 16 live images each Recording capability of D1@12FPS on all channels Net stream capable of decent images 3TB storage capacity 3-5 yr warranty Pentaplex And perhaps most importantly, a user interface that is not a convoluted hassle. This is for a Hotel where a front desk attendant and separately a security guard need to view 16 live images on their PC. They are not tech savvy. Ideally, they would clicck an icon on their desktop that lands them at log in screen/ they log in and land at a screen where they can elect to view all 16 cams.. e.g. highlighting 16 cam icons and then pressing 'live'/ then the screen would show a 4x4 grid of windows that populate within seconds. Intellicam (thanks Mike from Shoreview) can do this with their IE based browser, however there are PC's with no IE installed as a deterrent from surfing web., hence the need for a client. That said, I'd love to find a creative solution/ workaround. Any info is appreciated. The user friendly GUI is a must here. Rsvp Thanks Jeff

Hi there- Thx 4 reply. No I haven't. Can you elaborate? Can you speak to the features I listed?

Greetings: I'm trying to set up a Hikvision 8000 16 input DVR to use its NVR client software, and so far am being unsuccessful. There are fields labeled 'connect port' and 'dns server port' and, because I don't understand networks at this point, I'm having a hard time figuring out what to put in these fields. Any info is appreciated. Thanks

Greetings: A Hikvision 16ch PC DVR was working fine for hours, handling 5 remote clients connected, when suddenly 10 windows blanked out- no logo, no OSD- nothing. The windows appeared that way on remote PC clients as well as out of the unit's VGA port. In the DVR configs, the cams were all listed as 'enabled'. However, experience said disable and re-enable the cams and see what happens. After re-enabling 3 cams, all 10 showed up again It seems to me that the video card in the PC is just handling getting video images out to VGA and DVI monitors, yes? Or am I mistaken? I would think rather the video INPUT card or some circuitry on the motherboard would be associated with this anomaly. If the prob was just with the VGA output, then I'd be suspecting the video output card. In my thinking, the video output card has nothing to do with the generation of the video signal that is sent out over the network. To me, common sense says the anomaly occurs in circuitry that deals with camera input stream enabling. Dealer won't swap cards because, after re-enabling cams inputs, the problem hasn't shown up again in continuous 48hr operation, and I can't duplicate the prob. Comments? Anyone? Thx

The configs provide for weekly re-booting. Do you recommend that? Years ago I dealt with videoconferencing units (old PictureTel behemoths) and other AV content server type stuff. After finding that anomalies went away after re-booting, I ended up rebooting daily. An engineer mentioned something about a buffer overrun- in this case image data errors were numerous and created havoc with system. Rebooting cleared the registers apparently. Could be something similar going on here. After all, there's an awful lot of electronics and data zipping around in these machines

Soundy- Thx for expedient reply. Dealer did overnite me replacement video card, but I think it'd be a waste to open the package and swap out cards. Doesn't make sense. Figuring it was a glitch fro now. Will cross other bridges if they come up. Thx Jeff

Re: Storage: My understanding is that the captured DVR video data can sometimes be stored on an offsite (or onsite) server, in some cases via FTP. Obviously that data would be sent over a network via the network jack (Ethernet Port).

WrightSG- Is this Steve in Corning NY?

Hi William: Thanks for reply. It is difficult to communicate between different languages. I only know 1 language. Congratulations to you for speaking more than 1 language. I believe you missed some information in my previous posts. I see 16 images on 1 pc. While those 16 images are displaying on 1 PC, another PC only show 8 images. 16 + 8=24 total image between the 2 PC's. If i close software on each PC, then re-open, i see 16 images on the PC that previously displayed only 8 images, and I can see 8 images on the other PC. i was told by dealer that 8000 series DVR can deliver 16 images to many individual PC's at same time. i was told by person familiar with these DVR's that 8000 series can only deliver total 24images.. no more. Yes i have spoken to hikvision engineer and tech. Engineer says 5.29 version won't work with 8000 unit. Dealer sent me 5.29 and says it does work. Everyone tells me different thing. But still i have only 24 total images.I have tried this with default stream set to both main and sub. No difference thanks for offer to look at DVR, but it is on firewalled LAN. i don't know the port #.

Hi. Are you with Hikvision? You said 5.29 was 'a software from us'. Do you mean a software from the US? Or a software from Hikvision, which you are a part of? Re: Time: I am massachusetts in the US. Are you in Asia with a 12-14hr time difference? I was able to connect briefly on 1 PC. When I installed the client on additional PC's, even though the client was not activated on more than 1 PC, I suddenly can see only 8 cam images- the other 8 windows are completely blank- they do not even show the 'No Video' logo. The VGA output on the DVR does show cam images in all 16 windows. Even connecting via IE, I originally saw all 16 cams.. now I see 16 windows, but only the 1st 8 show images. This is crazy. I think the unit is defective. Any suggestions? Thanks

Hi - thanks for offer of assistance- how to contact you online? I will be at customer's site tomorrow Weds around 10AM ET trying to connect. Jeff

Hi mike- Thanks for reply- re: Client software version: The dealer sent me NVR client software and manual. The manual states version 5.05 The software zip file says V5.29 Wouldn't the port #'s be specific regarding how the site's network is configured? Thanks for offer of screen shots.. I'll send contact info off-list Jeff

The question 'which is best?', as you can see, is impossbile to answer. There are many factors to consider, as others have pointed out. I'm fairly new to the field, and I had a similar question when i 1st came upon the dozens of mfr's available. I've been doing alot of online searching and book reading. As others have pointed out, there are differences in GUI's, storage capacities, compression codecs, etc. Importantly, based on how the client plans to monitor the images or not, know that DVR's vary widely in their abilities to provide decent images in 3 separate but simultaneous instances: monitoring directly from the DVR; viewing over the internet; and the images that are actually recorded. Some DVR's offer great recorded images, but crappy web images. So- does the client need web monitoring? If not, then you don't have to pay for it. Some units can maintain high quality web live images while the unit is playing back archived video.. others can't. Alos know the mfr's use a sleight of hand of sorts when detailing their specs: the term FPS is typically frames per second, but mfr's vary widely: some are actually talking 'fields' per sec, other are talking 'frames' per sec. 2 fields = 1 frame. So 2 mfr's list 480 fps. if a mfr is referring to fields, that's really 240 'frames' per second.. half capacity!! And often they won't tell you.. unless you ask. And often the 'tech' on the phone has no clue! Good Luck But find out client needs 1st

thanks for replies, especially re: cctv.net- looks like what I'm looking for.. a simple 4in, 8out (2 outs per channel) non-matrixing BNC connectored distro to use with an already purchased DVR that has no looping inputs. And the suggestion that if i can unterminate the 75ohms at the existing quad box or DVR, I can tee off to the other component. In the meantime I realized I have a quad box removed from a previous job, which does have looped inputs. If the teeing off isn't available, and As long as the client is cool with a used device, I'll use the looped input box. Thanks again Jeff

Hi. I am upgrading to a new DVR, however the new unit has no loop through inputs, and the 4 cameras need to show up on a 4:3 color CRT monitor. Currently the cam inputs loop through the old DVR and on to a quad splitter. Since the new DVR has no loop throughs, I either need a 4 ch cmpst vid BNC distro with 2 outputs per channel, or I need a quad splitter with loop through inputs. Seems that I'm having a hard time locating these now. Anyone got any sources for these products? Or alternate solutions? Any info is appreciated. Thanks Jeff

Hi there: I'm looking for clips recorded on a DVR or various DVR's at different resolutions and frame rates, that I can play on a standard CD or DVD player, so that I can see the differences between low, mid and high frame rates and low, mid, and high resolutions. Ideally they would show people walking at typical speed in the interior of a building- bank, hotel, restaurant, convenience store etc as well as facial images, e.g. at a reception counter or cashier. Also looking to see quality differences in DVRs capable of varying IPS: 120 vs 240 vs 480 Will pay if necessary. Can you help? Rsvp Thanks
