You mentioned a foggy appearance on the lens. Try cleaning the glass in front of the lens (part of the camera body) and the lens itself.

Try using a video server to convert analog video signal to IP.

You have to enable port forwarding in your router before you can access your dvr remotely.

Try isolating the problem by connecting individual power supplies "wall warts" instead of the 18ch power supply. This way you eliminate group loop and know the faulty cable.

Try a restart of your modem, router and computer. Check you firewall settings.

Sorry for the misunderstanding Soundy. Actually I got your point in using wall warts instead of a single central power supply box. I am just wondering if bringing the AC power and plugging the wall warts near the cameras instead of plugging the wall warts using power strips has the same effect?

In case will running a new set of wires to supply power (110VAC) to the wall warts near the cameras from the DVR end eliminate the diagonal lines interference?

I have saw diagonal interference before and the culprit is the wire connecting the DVR and Monitor.

The easier way is to try changing the public port to another port # that is not blocked by your ISP in the port forwarding of your router. Although some routers will not have this feature. If this is the case, you will have to change the port apache is listening to. Go to the conf folder of apache and edit the httpd.conf file. Search for the word "port 80" and change to your desired port number. Save the file and restart your PC. You have to change to the new port number in your port forwarding in the router.

Try Perfect Keylogger from Blazzing Tools.

Sounds like you are using the DVR software to view remotely. Double check the port forwarding entries in your router if there's one installed before the DVR. Check with your ISP if the ports used by your remote viewer are not blocked.

As long as the voltage across the camera and dvr are within its voltage requirements (12VDC) and the amperage of the battery is more than the current requirement of the DVR and camera, the system should work.

Seems like both cameras and the PTZ are getting not enough voltage. How long is your cable run from power supply to camera? What is the thickness of the wire used for power?

Cable length has an effect on the signal and power. The longer the cable the higher the resistance, the lower the signal and voltage arrive at the other end of the cable. Google voltage drop calculator to know the power wire thickness required for your application. Although, I recommend powering the cameras locally for long distances. RG-59 and RG-6 coax are shielded and CAT5 UTP is not. In your case, I prefer to use CAT5 UTP because CAT5 has good resistance to EMI and RFI. One CAT5 cable can be connected to 4 cameras. If you have 4 cameras at the same location, just run 1 CAT5 cable is enough. Saves $$$ and effort.

If there's a router connected to the DVR, I prefer to use the free DDNS service/client of a router instead of the DVR. I encountered some DVR's DDNS client does not update to the right IP or the DVR's client kept on updating resulting to blocking of the service.
