How do you get 8 camera channels out of 4 Ports?

You'll need a PoE switch and a router. Someone had mentioned in previous answers that the NVR has 8 PoE ports that IS NOT TRUE. THIS UNIT ONLY HAS 4 RJ45 PORTS. For the other 4, you would need to add them from within the LAN but outside of the physical NVR. Why they didn't just have 8 ports.... who knows.

I'm guessing it's a mistake in the description. In theory you could have 8 ports with only 4 of them delivering power to the cameras (i.e. POE ports vs non-POE ports), but I don't think that's the case with the 7608. That said, I can't be sure because when I ordered this from TechVideo it came with no nameplate or designation and the firmware reports a different (presumably OEM) model number. The NVR I received does in fact have 8 POE ports. I'm currently running 5 cameras, all POE.

The Astak system has capability to handle four cameras on four separate channels. You can find additional cameras at Astak's home web page and probably for less at other sites. Just google Astak cameras and browse. Be aware you have to set a little switch on the camera's pigtail (Check the manual) to a channel that has not been selected already by the other cameras. Good luck, John H.

The camera can be used with up to 4 cameras. There are useful youtube videos which help in getting the additional cameras to communicate with the main base.

I would recommend and hdmi splitter that takes up one port but turns it Into three or more ports depending on the model I buyhttp://www.amazon.com/gp/aw/d/B008GVOVK0?cache=be13262daff0ab11004eb6b6ddd39105π=SY200_QL40&qid;=1405223702&sr;=8-1#

I am sorry you can't. Only support 2 analog cameras and 2 ip cameras at the same time.

Sorry for the delay in answering you...things have been a bit off track because of the long Holiday weekend Here is the answer from our technical people. You need 1 unit for 4 cameras. PoE provides Power and Data for camera up to 300 feet. Hope that helps, John Duncan 1-888-445-8375

Yes. The unit has an 8 port switch built in for connecting the 8 cameras. Each port provides POE power to the connected camera.

I have never tried that, but I know it handles all 4 IP cameras really well simultaneously. I am currently using just the VGA output to a "cheesy" monitor. Since I use it mostly via remote viewing!!

According to the manual:1. Turn monitor off.2. Press and hold the "+" brightness button on the right side of the front panel, and concurrently switch the monitor on. (monitor shows the pairing screen)3. Once the pairing screen comes up, switch the camera on and use a pin to stick in the small hole in the bottom of the camera (pair button). 4. The power LED on the camera will blink when successful. 5. Monitor will say cam1 ok and prompt you to add more cameras. Repeat the process until additional cameras are added.

This DVR can have up to 8 cameras hooked up to it and doesnt need adapter for it , at least my set up didnt need any adapter. It has 2 four-way hook ups that came with the QS558-852 8 channel system.

This comes with 4 cameras so you'll only see 4channels. It allows you to have up to 8 channel so you can buy extra cameras n have all 8 channels showing

This is a four channel model so you cannot upgrade. Check out other eight and sixteen channel models which allow you to add additional cameras.

No, each camera has a power requirement that is met by one port on the PoE switch.

1) Did you check to make sure you did not accidentally reverse the power/ground wires? 2) You said 18 channels - some cameras can consume a lot of power; Is your power supply adequately sized (plus some margin) to deliver power to all your cameras? To check this, I would unplug all cameras except for one. Then add in more cameras one by one. 3) Using a volt meter (and measuring resistance), did you check to make sure you do not accidentally have a short circuit somewhere? If your DVM shows 0, or something close to it, you might* have a short.

Not sure if this was what you're asking but next to the DVR you will need to have a regular receptacle to plug the cameras into four cameras per plug. And I am super happy with the system I have

The 8 channel you can add up to four additional cameras. Its' a great system.
