As far as I know, the Wavejet technology from GE used on the DVMRe/Storesafe improves the compression algorithm to be able to store twice as much video per megabyte versus wavelet. There are no claims of better picture quality. One thing to keep in mind, is that the DVMRe records at 320x240 and the remote viewing over IP is also 320x240 at least for the models I am familiar with. It is solid as a rock, though.

Well, this is a little off topic, but as long as you brought it up. I was using a CAT5 cable to access a GE/Kalatel DVMRe remotely using a KTD-405 keyboard. It combines signal and power over the cat 5. I was in a hurry and needed to re-purpose the cable for a network connection. I unplugged it from my keyboard and plugged into my network switch and promptly blew out my switch because the other end was still trying to send power to the keyboard. Expensive lesson.

No, they do not. I saw where Pelco was going to bundle a one license version of Milestone, but you can get that from the Milestone website anyway for any camera. The Panasonic web interface has a simple Live and Quad view, but that is it. Picture quality on the Panasonic is very good, especially in low light but it is not megapixel. I tried to post an image but it gives me errors. The Pelco keeps disconnecting from the server so I have not mounted it outside for comparison.

Just to close out this thread. I ordered a Pelco IP110 camera and a Panasonic NW484 for comparison. The Pelco I received was defective (the light doesn't go on on the network switch when you plug in the cable) so I returned it. The replacement was also defective so I called their tech support. It turned out to be the next consecutive serial number as the first one, so probably they had a manufacturing issue. Anyway, Pelco tech support received and confirmed the second camera IP interface was bad, repaired it and sent it back to me. I can now report that the Pelco IP110 is in service and am running it along side the Panasonic. One obvious difference is that the Pano supports M-JPEG and the Pelco does not (except when connected to Endura). I have to say that the Pelco does a nice job streaming MPEG over multicast at 30 FPS. Took several tries to get the Pelco configured with Milestone. The Panasonic worked first time. While waiting for the Pelco to be repaired, I did end up ordering 2 more Panasonics. One issue with the Panasonic is that the web interface does not work under Vista. No issues with the Pelco interface under Vista. Both cameras run on POE. Hope this is helpful. Andy

There are at least a handful of vendors who claim Coaxitron support over baluns. Here is one https://www.blackbox.com/files/productdetails/23836.PDF

If you have a multichannel modulator, you can modulate different cameras to different channels and then the client can use the TV remote to change channels. If your TVs have a lot of AV inputs, you can run multiple signals from your DVR to your TV using CAT5 and a 4 to 1 balun on each end and then go into AV1, AV2, AV3, etc. Not quite what you were asking, but maybe it will prompt some ideas.

Rory, good luck. Unfortunately, a simple continuity check on CAT5 does not guarantee that you will be able to pass Ethernet traffic. I recently ran 6 cables - all checked out good with a cat5 tester - crimped rj45s on one end and keystone jacks at the other end. 5 of the 6 worked perfectly, but the last one did not. I cut off both ends of the bad connection and crimped them again. Still no joy. Most likely, there is a kink in the cable somewhere which allows the continuity test to pass, but won't allow 10/100 mbps to connect.

Well, by searching on these terms it was easy enough to find out which camera's brochure you were reading. No Accumulative Error with Preset Function. This means that regardless of how much you pan and tilt around you will always come back to the same place when you select one of the presets. Shortest Path by Vector Drive Technology. This means that if you are going from preset 1 to preset 2 and it involves an x and y movement, the drive will figure out a diaganol path (vector) instead of first moving x and then moving y High Accuracy with Micro-Stepping Control Technology. This indicates the precision with which a location can be selected. (see correct explanation below) I'll leave it to you to separate the marketing hype from the unique features.

As I reread the original post, I believe the reference to 'POE box is suitable for everyone used to DC 12V power supply IP camera' is similar to the Diswire POE12E. This basically goes at the camera end of a POE injected ethernet cable and splits off the signal to go to the camera and a 12v power jack. I have never used this because the IP cameras I purchase all have POE capability.

PTZ works great if you have a dedicated security team who sees something suspicious like a shop lifter, person in the parking lot, etc, and the guard can use the PTZ to zoom in and track what the person is doing. Using them to scan or do guard tours is generally not very satisfying unless you are looking for relatively static targets. I think you give the owner one PTZ to play with and consider swapping the other one for 2 fixed cameras.

I just installed one of these for a door cam in case you are still looking at other options - good picture. Sony SSCCD73V 1/4'' Super HAD CCD Color Ruggedized Day/ Night Mini Dome Camera with 3-8mm Auto Iris Varifocal Lens

Agreed for 'normal' cable. The thing to look out for is digital cable which may be using those channels for pay per view.

I wish you luck. In the past, I have tried similar modulators and everything looked great until I tried to combine the signal with the cable TV feed. At that point, the background 'noise' on the supposedly unused channel causes significant degredation making the signal unusable. Of course, to do it right, you need to run the incoming cable TV through a notch filter to drop out the channels you intend to add, but good luck finding a notch filter that drops out channels that aren't in use. In the end, I usually end up distributing the video over cat 5 using a 4 to 1 balun. For example, from a GE DVMRe, I can send monitor A, B and 2 dedicated cameras over the 4 pairs, so for each TV I can choose what I want to view and most TVs have multiple AV inputs these days.

You are right. Traffic through the modem is a small fraction of the bandwidth of a switch, so you should optimize the computer to server traffic and not worry too much about the traffic over the modem line.

Just trying to understand - POE cameras are not new. For example, on my desk here I have a Panasonic WV-NW484S which is running on POE. Also, it is getting power from a Netgear switch which has built in POE and does not require a separate power injector. What feedback would you like from this forum?

Analog camera to video capture card to disk is very easy on LANs and WANs

It really comes down to FPS - my last installation I set the video server on 2 frames per second normal with 8 frames per second on motion detect at 4CIF resolution which worked just fine. Many people posting on this forum are looking for 30 FPS, which gives a beautiful smooth picture but burns up a ton of disk space and bandwidth. At the lower setting, you are using about 2% of a 100 mbps LAN. At 30 fps, 4CIF and 4 cameras, you are using about 75% of the useful lan capacity.

The Axis 241Q is a solid performer with high bit rates on all 4 ports but will probably cost you over $700. The 240Q has lower bitrate and is the range you mentioned. I have attached analog pelco, sony and other brand cameras to the Axis and been happy with the results feeding into a Milestone back end. You will still need to ensure you have the right bandwidth between the locations if you plan to transmit it all back to a central server. Another alternative is to have small DVRs locally and use the back up functions to copy the files to a central server or NAS at the end of the day. Set each location to backup at different times to reduce overall load on the network. Good luck!

Just so you know, any good IT department, especially in a financial institution or technology company which is concerned with intrusion detection, would detect and be able to locate a wireless lan even with SSID broadcast turned off - but I'm not sure how sophisticated the group is - and you probably don't want to say too much about the business to preserve confidentiality.

Is the problem that you are getting video ok through the BNC connection but that you cannot control the PTZ? What type of cable connection are you making - from the camera RS-485 port to the pc/dvr 2400 - or are you counting on the multiplex-coaxial connection?

Are you trying to capture the contents of the display case or the face of the people in the store or both? Given the extreme differences in lighting, you might actually be better off using separate cameras, one focused down on the display case which can adjust to the cabinet lighting and one from behind the counter towards the showroom.

Are you only transmitting video or do you also need power? Depending on what NVT converter you are using, some are just single camera - single twisted pair, others are some combination of multiple camersa, audio, power, etc. I like the ones that take a CAT5 cable directly into the converter which usually works fine unless your camera has a heated enclosure and needs more power. With regards to specialty cables, GOOGLE on terms including SIAMESE CABLE UTP and and you will get a bunch of hits, hopefully one that ships to Mexico. Andy

Carl, tell me where this goes wrong. The PC that has the GV1480 is attached to your D-LINK DIR635 has gets assigned a dynamic IP address of say 192.168.0.100. When you connect to the webcamserver from another PC on the same lan it works fine and you see the webcam. Now you go into the Port Forwarding page on the router and set up 192.168.0.100 with TCP enabled, Port 80 and inbound filter 'allow all'. Also, you check the WAN IP address of your router and find out that your outside IP address is something like 65.5.65.5 (i made that up). Now, from a PC outside of your location, you go into a web browser and bring up 65.5.65.5 hoping to see the webcam - does it work? As Rory suggests, you can change it to use another port such as 8080 on the web server, then you need to configure that port in the port forwarding and finally you need to use http://65.5.65.5:8080 to view the page.

A lot of times people start with technology questions - like what pc or what camera - but it is very important to start with the usage questions. What do you really want to do with the system? What are the 2 cameras for? Is this mostly for real time monitoring, or do you want the cameras to record what is going on when you are gone? During playback, are you trying to identify people, cars or what? Is motion detection important? How much load are you planning to put on the PC other than using it as a DVR? Having said all that, any modern PC is probably good enough for a 2 camera system. At 1440 or 1600x900, you probably have more screen real estate than your 2 cameras have pixels. Video capture card will run $100 to $400. Software will run $50 to $300 for simple functionality. Night vision cameras go for $80 to $400 for casual use. Sorry for US$ since you said you are in the UK. If I were you, I would seriously consider picking up a simple dedicated 4 channel DVR instead of using your pc. Then run the remote client on the PC for playback. Andy
