Andy is offering a NVR4104-P-4KS2 at a nice price - but when I Google "dahua NVR4104-P-4KS2" I see images of the white rectangular NVR with rounded corners. Your link shows the correct image. But when I click on
Dahua NVR4104-P-4KS2 NVR 4 Channel Smart Mini 1U 4PoE 4K&H ... for example I get the white box with the rounded corners.

How can I be sure what I'm going to get? :confused:

The versions Andy sells are the International versions. I would consider the international Dahua site to be correct. But your mileage may vary. Ask Andy to send you a pic.

HELP! (Again!!) If it's not one thing it's a dozen. I've setting up my SD49225T-HN in my living room to check out all the parts and connections. This afternoon I put the Microseven POE splitter in the Ethernet line. I still get a picture. Yay! And I hitched up the Microseven mic. I get audio! Yay!! But the splitter gets hot, Hot, HOT. I don't think it will endure the hot sun of a mid-summer Texas day.

So..., recommendations for a POE+ gigabit splitter? I'm looking at a SMAKN® Active Gigabit PoE Splitter on Amazon. Any thoughts?

Just curious, any thunderstorms lately?
No, been several weeks since we've had any lightning. Weather's been great! Not even hot outside like it was during the middle of summer, so that should rule out overheating.

Contacted Andy over the weekend and he asked if it happened suddenly and if I had checked the POE switch, to which the answer is yes to both. Waiting to hear back from him on the next step.

Edit to add: While I mention the weather's been great from a temperature and lightning standpoint, we did have blowing rain about a week ago from the weakened remnants of that hurricane in the south. I had not thought anything of this since these units are supposed to be IP66 compliant, however I see another thread where someone discovered water inside their unit after the hurricane from the blowing rain. If that's the case, then these are not IP66 compliant and perhaps the blowing rain found it's way into mine too? I haven't noticed any fog or droplets on the lens like the other poster did, though I imagine the POE module is near the top where the cables enter the unit. Perhaps water made it into that area somehow and shorted out the POE module on mine and just hasn't made it way down to the lens section near the bottom of the unit yet?

Just speculation, though kind of ironic that it worked until a few days after our first real blowing rain while someone else experiencing that same storm system had water blown into their unit...

Don't have a recommendation on the splitter, but note that the camera is only 100Mbps so that may open you up to other options. Also keep in mind it requires PoE+, so even though the splitter is converting to 12v you may want to look for a splitter that can handle the higher wattage. According to my PoE switch, my camera is drawing 14 watts with the IR illuminator on, not sure if it spikes higher on the initial power up or when the PTZ motor is active.

Thanks m3b for that insight. Even though the camera is 100Mb/s I thought I would future-proof myself and go with gigabit components. So I ordered the SMAKN® Active Gigabit PoE Splitter. It is supposed to deliver 24w at 12v. It's good to know your cam uses 14w with IR on. The little NVR I've got on order is rated 50w overall for 4 ports. N42B1P from B&H. I thought it would be good to power two cams but it looks like it will do four based on your data! Much appreciated.

It's probably been discussed already, but how do you control the PTZ? If I see some shenanigans going on, I'd like to zoom in quickly rather than having to log in to SPSS or through a web browser. Is there an easier way like the Dahua PTZ joystick, but cheaper?

Wasn't sure whether to post this here or in the Milestone section but has anyone had experience with this camera using Milestone XProtect 2017 R2 (free version) with regard to controlling preset PTZ positions, everything else is working well for controlling this camera, I imported PTZ presets and they show but the camera doesn't respond, my guess is this could be linked to user permissions/accounts with the camera. On a side note, this camera continues to impress me, at night it is superb for close to medium range, IR illumination is excellent, I can't really fault it for the money - easy to see why they are popular. Appreciate any ideas or advice on the preset issue. Thanks.

Find any moisture?
Oh yeah! Lots! Apparently, these aren't designed to be out in the weather. Soon as I got the screws of that top part of the dome half way loosened, brown/rusty water started rolling down the sides of the dome and was soaked all inside. Fortunately, the bottom (black) compartment (where the actual camera is located) was completely dry, so the leak was only on the top portion of the housing. Since everything else seems to work when powered via 12V, I'm assuming that replacing that circuit board with the black spot should do the trick. The black spots must be on the POE connection.

There was also some black corrosion on the wires that plugged into that spot, which concerned me that maybe the wiring needed replacing too...But when testing the corroded wires with a multimeter on Ohms, was able to get a reading when touching those wires along with a pin on the ethernet input, so obviously I'm getting at least some transfer throughout those wires. Hopefully it's enough.

Unfortunately, Andy hasn't gotten back with me on a replacement circuit board. If he can send one, I'm willing to do the labor as it's just 3 screws and 3 wiring harness plug-ins and give it one more chance....Though it's been nothing but problems since day one and I'm starting to wonder if I'd be better off giving up and requesting a refund. If the thing isn't even waterproof, then what's going to stop it from doing the same thing next good rain that comes? Feels like I'm just patching and buying time.

So much for the supposed IP66 rating. :facepalm:

This is a concern for current owners :eek: - there must be others exposed to very poor weather, is this the first documented case :idk: Wonder if the 59225 is sealed differently, this type of PTZ design must be inherently difficult to protect from the elements I should imagine. I would be less surprised if the water had got into the lower black section, the top seems to be pretty well sealed off with just the cable gland and main body seal. With that being said in operation they are excellent!

I would think if a company like Dahua states it rated IP66 then it is weather sealed unit.

I suspect something came loose maybe a screw that compress the weather seal came loose due to the PTZ vibration or a seal wasn't compressed enough on the assembly line when it was assembled.

Company like Dahus would have lot to lose if they start to cut corner and lie about thier product spec so I doubt they are doing this.

I'd try to file the corrosion off those pins. Maybe a nail file. And some contact cleaner if you have any. Since it works with 12 volt, might just be bad or no electrical connection on those pins.
