Thank you again for your help. Camera spec is: Power Supply AC24V, 3 A (± 10%) Power Consumption 10.5 W, 26 W with IR on Power adapter spec is: Output AC24V(±5%), 3000mA Thank you again for the help.

That's very good and very helpful information. Thank you very much. Would you have a 2 wire brand, gauge recommendation for my application? I think someone just used plenum speaker wire. I didn't think it was wise when I heard it but i honestly don't know. Thanks again.

I purchased a Dahua 6C430UNI PTZ dome that requires power from an adapter (24V 3A). I thought it might be PoE but it turns out that it needs separate power. I would like to leave the transformer near my DVR connected to a UPS. I need about 100 feet of 3 wire cable to run power (black/red/ground) that can be run through a wall and survive in a very hot attic. I've searched but have been unable to find advice on what cable to buy. It's this adapter if that helps: http://www1.dahuasecurity.com/products/ac24v3a-13601.html Thank you in advance, Peter

Thanks for the reply Blackshield. I had a hunch IR LEDs themselves might not get me what I wanted. I'm hoping laser might though. Even if I'm limited to 75' at night, I'd still like a system that could clearly capture plates and faces much further during the day. I'm betting someone has crafted a solution that works pretty well without breaking the bank and I'm hoping they'll share.

I have a couple of the Costco special QC804 systems with 4 QC/Dahua 720P cameras each that I bought and installed a few years ago. They been good systems and I'd happily buy Dahua going forward. The only downside is that they are unable to capture license plates (day or night) at about 75+ feet. Ideally, I'd like to be able to clearly capture license plates at 150' or more day or night. I'm looking to add a couple of high resolution IP, POE, PTZ IR or Laser Outdoor cameras with another dedicated DVR. 20X to 40X optical zoom would be nice and, of course, best bang for the buck would be nice. Does anybody else have a system like this they could recommend? Thank you in advance.

I have a some Q-See 720P bullet cameras (Dahua ipc-hfw2100 / Q-See qcn7001b) mounted in my soffits. Unfortunately, my soffits have about a 3 inch lip on them so at night the IR backwash clouds the night vision pictures. I can't point them down any more or they won't be at a useful viewing angle. Has anybody found an OEM base/spacer for this camera or come up with some other clever way to move the camera an inch or two away from the mounting surface? I'm considering just cutting some 2X4 blocks and drilling a hole in the middle and mounting it to the soffit then the camera to it but I'm wondering if someone has come up with something more aesthetically pleasing and more professional looking? Thanks in advance.

One last post on this (I hope). So far the issue has not returned. I still don't see how enabling DHCP and disabling UPNP fixed it (since the IP address, SM, GW remained the same on the DVR/NVR and the port reservations remained as they were in the router) but so far this seems to have done the trick. Hopefully this thread helps somebody else because that fix isn't very intuitive (to me anyway). Again, I sure appreciate the help.

If all else fails, disable this option. And if ports have been forwarded, than for sure turn it off in the router/NVR [or dvr]. Hopefully no other wireless devices on your network depend on UPNP. I'm not saying that it's definitely the problem, but UPNP can cause odd issues sometimes. Good luck. I wanted to say thanks again for everybody's help. I ultimately called Q-See and they told me to enable DHCP (instead of the static address I had) and disable UPNP. I did both (not sure how DHCP helps since it still has the same IP, SM & GW). Anyway, so far (2 days), the ports have remained on the router, external access still works and it hasn't kicked everything else off the home network (yet). It has gone as long as a week without causing this behavior in the past so it's a bit early to call it a win but I'm hopeful. Thanks again.

dexterash, Plugging it into the switch didn't help but thank you for the suggestion. shockwave199, I may have my terms wrong. I don't know if it's an NVR or DVR to be honest. I'll take a look at the port forwarding as indicated by the manual. I know I'm using the default ports and UPNP as I've reset all devices a few times and notice the port forwrading automatically get's set up on the router (and external access to the DVR/NVR) works. Thank you for the advice. f46power I'll take a look at this as well. I can't remember if I put modified the DNS server entries after the last reset. It may be back to the 4.4.4.4, etc... default settings. Thank you for the advice. Thank you all.

dexterash, Thank you for responding. It's currently directly plugged into the router. I did try through a second router briefly but feared the 2 router setup might be part of the problem so I removed it. I do have a Cisco switch I can try so I'll try connecting the NVR to the switch which is connected to the router. Thanks.

I have an odd challenge and I'm really hoping someone else has seen this and found a solution they'd be willing to share. I have a QC804 NVR (which I believe is a Dahua product). When I connect the NVR to my home network (Verizon FIOS) router, after a few hours (sometimes more or less) all other devices on my network begin to lose network connectivity. Basically the Verizon router (Model #: MI424WR Rev F) slowly grinds to a halt. Even the Verizon DVR and set top boxes start to become unresponsive. If I turn off the NVR or pull the network cable, everything goes back to normal. What on earth could the NVR be doing that causes the Verizon router to become unresponsive? It's almost like the NVR is running some kind of DOS attack on the router. The network configuration on the NVR seems to be ok. I'm able to connect to it externally and view the cameras, etc... Has anybody run into this? Any help or advice would be greatly appreciated.

Thank you again very much for the information. The more I learn, the more I realize how much I don't know but that has great value. I think I'm going to follow yours and other's advice and go with more of a beginner DIY system at a much lower cost. I think the Dahua/Costco 4cam/NVR deal with a few lens swaps will be a good starting point for me. I really appreciate the help.

That's a really impressive camera. The zoom is amazing!! Looks like the Outdoor version (WV-SW395) is about 2 grand. That may be a bit more than I'm willing to spend but it's really good to know there is such a camera.

Wow! Nice blog. Thank you very much for the information. That's a really impressive camera and may work perfectly for my application. Did you get a chance to test the "Auto tracking: Pans/tilts to follow a moving subject"? I'd love to know how that worked. Thank you again very much for the information.

I apologize as I realize I'm just talking to myself in this thread but there might be another noob that benefits. I just realized that these cameras can't be remotely aimed. I thought dome cameras were all able to be remotely aimed (derp). I would have made an expensive mistake. I’m back to thinking the Q-See/Dahua/Costco deal might be my best bet if fixed cameras are in my future anyway.
