    A Dahua Camera Conumdrum...

    All the low-voltage wire was put in at the time of construction, 40 years ago. The only thing that wasn't put in was coax for TV cable. Heck all the lights in the house are controlled by 18v relays! My utility room has a huge 66-board that distributes the 25-pair cabling to every room in the...

    A Dahua Camera Conumdrum...

    Well, of course you need to pick the pairs carefully. If you mismatched the pairs in Cat5 it wouldn't work well either (and I've done that! LOL!). Frankly, I don't expect the telco cable to work for this, but have to try due to the real difficulty of running the new Cat5. As I said, I'll...

    A Dahua Camera Conumdrum...

    Remember, it is twisted pair, and there's no longer even a single phone pair in there to crosstalk with. Almost all the old telco twisted pair cables were "rated" to Cat1, but actually performed to Cat3 or better when tested. As I've said, running the new Cat5 cable properly is a huge job...

    A Dahua Camera Conumdrum...

    I know I "should" hardwire the whole thing with Cat5. The problem is that I'll have to do at least two runs of nearly 200 ft each to get to where the POE switches are located, and the way the house is built it's impossible to do a continuous run inside the house, even through the attics (two...

    A Dahua Camera Conumdrum...

    So, the pathway here is: 1. Buy the full version of BI 2. Try it with the 9 cameras to see if it runs. If it runs, excellent! If it doesn't, continue... 3. Run ethernet cables through the house to the switches and bypass the powerline adapters. If that doesn't work, try to get a refund...

    A Dahua Camera Conumdrum...

    A follow-up question... just how many cameras can I run in demo mode to make sure it's working?

    A Dahua Camera Conumdrum...

    So, what you're telling me is that with 9 cameras, the system in Demo Mode won't even run it when I'm only watching the cameras and am not doing ANY recording, and have Zero motion triggers set? I would think that all the cameras would be equally affected, not just the cameras on one leg of the...

    A Dahua Camera Conumdrum...

    At this point, I'm not even trying to record anything... just trying to get the system to run. On the occasions when it behaves, the CPU is only running at about 30% MAX (its an i9 box, so should handle a lot). Yes, I have a few hundred feet of Cat5 cable, so had planned to try doing a...

    A Dahua Camera Conumdrum...

    It's beginning to look like a Network Neurosis... After swapping the camera to the other network leg, it's running like a top! And the bad leg is still misbehaving. I fear I'm going to have to run Cat5 for the entire network to get it to work. It's a very big and old house, and getting cable...

    A Dahua Camera Conumdrum...

    Yes, I am using demo mode for now... don't want to pull the trigger on buying the software until I can get this system to run.

    A Dahua Camera Conumdrum...

    No fluorescents on the leg with the problem, and a potential problem with refrigerators on the circuit was eliminated because the problem is still there with them unplugged. I'll try swapping with a camera on the good leg and see what happens. I would go ahead and replace the camera right...

    A Dahua Camera Conumdrum...

    I've set up a 9-camera system, using the Dahua 4300S series, along with some of the newer Dahua 1320S cameras. Individually, each camera works just fine with Blue Iris. However, when all the cameras are running, the data rate for one of the cameras will drop down to almost nothing, and often...

    Troubleshooting POE on HFW4300S V2

    LOL! I hear you about the HF Quality trade-off. But it can be used to your advantage... I know a guy who bought one of those HF angle grinders, plus the extended warranty. When the beast expired in about 6 months, he took it back for a replacement, and bought the extended warranty on than...

    Troubleshooting POE on HFW4300S V2

    I'm partial to using the self-fusing silicone tape to provide the "belt-and-suspenders" approach to sealing the connection in very exposed locations. I haven't tried the Harbor Freight version, but it should work pretty well if used properly. I've had a couple of the Dahua cams arrive without...

    Troubleshooting POE on HFW4300S V2

    Thanks! That's pretty much what I thought was going on. No, the POE light on the switch does not light with this camera. The POE splitter would certainly do the job, but I'll opt for the "dumb" POE injector for about the same price. Weatherproofing the connections for the splitter would be...

    Troubleshooting POE on HFW4300S V2

    Well, the problem is definitely within the camera. Other cams work fine with the cable to this cam, and other, verified cables don't change the POE behavior of the camera. I haven't done a reset or firmware upgrade, as I consider that as a last resort before junking a camera that was once...

    Troubleshooting POE on HFW4300S V2

    I guess my next question would be "How do I do a hard-reset on this camera?" I've disassembled it and can find no obvious reset switches or jumpers on the camera board.

    Troubleshooting POE on HFW4300S V2

    Well, the problem with my camera isn't the RJ45 jack/keystone as I thought it was. This is a camera that has been in service for a year or so, and has previously had no problems. Now, when I'm connected to my TPLink POE switch, the camera does not power-up. I have tried each of the other 3...

    Need wire pinout for Dahua HFW4300S V2

    Thanks Sean! Unfortunately, since Dahua doesn't seem to use any standard wiring code, it doesn't help much in my present circumstances. I will save the info for when I need to work on one of these cameras. As it turns out, the RJ45 keystone may not need replacement... it may be a...

    Need wire pinout for Dahua HFW4300S V2

    Ok, I've done it the hard way... carefully slicing a spot of insulation off the green and yellow wires. The green wire corresponds to POE- (the brown/brown-white pair at RJ45 pins 7 & 8). The yellow wire is for POE+, RJ45 pins 4 & 5. Now comes the "fun" part, connecting these wires to a new...

    Need wire pinout for Dahua HFW4300S V2

    I need to replace the female ethernet jack on my HFW4300S V2 (or directly splice to the cable with the ethernet pigtail). I found, unfortunately, that Dahua does not use any standard color coding for the wires to the RJ 45 pigtail and the 12V injector pigtail. Where the wiring plugs to the...

    BlueIris 64-Bit and IP Cameras

    That 1MP cam from Nellys looks like a rebranded Dahua. If you don't need vendor support, consider buying from Amazon or even Alliexpress. You can get a 3MP cam for only a little more. If you need vendor support, however, plan to spend just a bit more.

    Viewing BI via Remote Desktop

    An update... Well, I did end up having some network throughput issues and they first showed up where I expected, in the music streaming of "internet radios". I went back through the setup and backed the remote desktop view to 5-second intervals, and also dialed back several other settings, and...

    Viewing BI via Remote Desktop

    At present, it's only 5 cams, running 5fps. Server is core i7-4790 w/8GB RAM. If this can max out the Remote Desktop connection, I'm probably going to have lots worse problems down the road. I use the same network for streaming Music to a couple of players in the house, so if I start maxing...

    Viewing BI via Remote Desktop

    Perfect! Thank you fenderman! I knew there was probably a setting someplace for this issue, and your suggestion was just what I needed to do.

    Viewing BI via Remote Desktop

    Well, my learning curve is progressing, and I've managed to set up and use Remote Desktop to access my BI server. One odd thing I've noticed is that when I view the live feeds of the BI cameras (5 cams at this point), via Remote Desktop, what I see only updates every 5 seconds (give or take)...

    Slow framerate on just one camera...

    Well, I can't say I found the cause for sure... but at least it seems for now to be fixed. I have done the Malwarebytes scan, and that got rid of most of the problem. However, I still had to reset both Internet Explorer and Firefox, then reboot before the Cyti Web was (from all appearances)...

    Slow framerate on just one camera...

    Well, it was a clean install (embarassed shuffling of feet while I think about the malware). I may have to resort to that if the problem returns, but for now the bug seems to have been banished. The problem with a "clean install" is that I'm starting from Windows 8.0 Pro. Doing all the...

    Slow framerate on just one camera...

    Well, many thanks to all for all the suggestions. The problem is resolved, and the framerate is behaving as it should. As to the source of the problem, it's somewhat of a mystery. The one issue that I have now determined was coincidental with this was a nasty bit of malware/adware (Cyti Web)...

    Slow framerate on just one camera...

    Thanks for the suggestion... I'll try that. However, both installations are the 64 bit, and the one on the slower machine seems to work just fine... we'll just have to see, and it's not all that much trouble to reinstall as 32bit
