  1. Depending on how close you are to the building and any line of sight options, a point-to-point wireless solution using something in the unlicensed spectrum an option? If you do put a PC in the property, put it in the most hard to get, hard to find, and impossible to remove location. Any thief breaking in will happily steal an easily accessible computer...which defeats the purpose of doing all of this in the first place....

    That looks like a MAC address in the txt file.

    Dahua camera cable

    I tend to believe the hype that it was all about making a cheaper camera. Seeing as how a lot of your cheaper IP cameras are coming with this train wreck attached to the pigtail now, I can't see them caring about longevity half as much as they care about shoveling as much product out as they can as cheaply as possible. I'm also a "negative Nancy" As sad as it is to say though, if I can get these for $80 a pop I'll probably still buy them and end up fussing around with adding a POE board, pigtail, and plug.

    Possibly, but the 4300s is only rated as 5.5w max draw and the 4800e is 7.5w. Hard to imagine that little of potential heat would cause issues. I have a couple different POE boards on order from China that should be small enough to fit in these 4300s that I have. Contemplating putting an EtherCon style fitting on the end of a short 6-12" pigtail.

    The POE box on the 4300S V2 cable has the 802.3af logic on it as well as a 12v voltage regulator. There are two feeds to the camera board, a 48v and a 12v and when plugged into a 48v passive injector both feeds are powered. The camera board runs off of the 12v feed, if I remove those two wires from the plug the camera board won't power on. No idea why the 48v feed is brought through to the camera board. Need to find a 12v power adapter and see if it energizes the 48v feed. Red(+) and Black(-) are the 12v, Yellow(+) and Green(-) are the 48v, and the blue/orange/purple/brown are the two data pairs. Has an unbranded (knockoff??) TPS2378 POE chip in it which the official version is 802.3at complaint.

    I could live with one like the last picture, cable is still too long but it is manageable. I have one 4800E here that has that silly POE box on the cable. I am mounting these on brick walls and really don't have much of a place to hide the excess cable length and connectors. The junction box I am having to use to hide all of that cable is larger then the 4300S itself. Any recommendations for a official USA reseller? I'm installing a couple camera's here and there and eventually will have around 20-30 of them, thus shopping around. Amazon was the safe trial run (easy to return....if I had saved the boxes....) I have a few outstanding orders off of AliExpress, waiting on delivery so I can verify them but from the sounds of it I likely will be getting the same V2 models. Going to break open a 4300S tonight to see if I can't hide the innards of the POE box inside the camera and have a short 2-3" pigtail of a cable coming out of the camera.

    This the "V1"? Know if they made anything else cheap on it, or just the external POE converter?

    Amazon. Bought several over the past 2-3 months and they have all had it. Couple different sellers too. Crap, I already threw the boxes away. So they normally don't have that thing and whatever electronics are in it are inside the camera instead?

    Wait.... Is that thing the actual POE converter? They couldn't have put a the 802.3af power chip inside the camera!???!?

    Dahua camera cable

    This is what the cables on all my Dahua camera's look like. Base of camera to end of cable is maybe 8-12" long. I would break out the wire cutters, soldering iron, and heat shrink tubing but that is a lot of effort if there are other alternatives.
  11. Does anybody know if there is an option for it or even a way to custom order a different cable for Dahua camera's? In particular the IPC-HFW4800E and IPC-HFW4300S. I'm looking for a cable that comes out of the back of the camera only 4-6", only has the ethernet plug, and does not have that large rectangular plastic box on the cable. I mount the camera's to round junction boxes and keep all of the wiring inside the box, but it is hard to do with the existing cable pigtail as it currently is.
  12. The Bosch Dinion Starlight 8000MP looks like a pretty amazing camera.
  13. So, the Hikvision camera's have issues but the Trendnet does not? Are the Hikvision camera's on longer cable lengths then the Trendnet? What brand/model is the switch? And are you able to confirm that it drops pings locally? Or only when going over the wireless? Turn on logging on the Nanostations and attach the logs with the time of when the problem happens.
  14. The "Active/Passive" is above my current pay grade... but I will dig in to it later. Hopefully cleaning contacts tomorrow will resolve this. Dunno if "Pattern" is too strong a word, but there is a certain repetitious nature to the Ping responses: Get us the make/model of the switch and/or the make/model of the camera's. Chances are it is active POE (802.3af). From the latency I am guessing you are pinging from the Blue Iris server or some other computer at the server location? Looking at the ping output there are a couple timeouts and then the destination host unreachable messages. The "Destination host unreachable" means that there is no route to the host, either on layer 3 IP or layer 2 ARP. Since you have a bridged network it more then likely is layer 2 ARP. The unresponsive timeframe is roughly the same which seems to be about as long as a camera boot time My supposition. Due to cable length, poor cable, poor connections, or a bad switch, you are having your 802.3af POE power drop in and out causing the camera to reboot. The first couple seconds you get the ICMP timeout since the ARP entry still exists on the switch and after that it flushes and you get the destination host unreachable. Camera boots back up, ARP entry added to the switch, and all is good.
  15. Active (802.3af) or passive POE? Are you able to see if the camera has any sort of uptime/log that would help determine if it is a power or a network issue? 802.3af must negotiate POE and cabling issues affecting the power wire pairs can cause bouncing which will appear like the camera is continually rebooting. Wire issues can affect networking too run "ping -t 10.0.0.147" to see if there is a pattern on the ping/no ping timeframes.
