    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    Well it seems I'm not having the best luck with my new Dahua cam. It now loses connection about once every 4 or 5 hours? I can reset it by removing power and applying power. - The cat5 cable has been tested, sat. - The 12 VDC / 5 amp power supply tested sat - Using the default IP address which...

    Huisun 10x v1 mini PTZ completely dead

    Thanks for the info gpower. Any ideas on how to obtain the board? My attempts to acquire parts or help from Huisun failed miserably.

    Huisun 10x v1 mini PTZ completely dead

    My Huisun 10x v2 died 4 or 5 months ago (finally replaced it with a Dahua). In my case, the camera was always powered by 12 VDC (not POE). Before it's failure, the camera would sometimes lose it's capability to focus automatically, and to correct it I would remove power then apply power and all...

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    Hey brcarls, here is the info from another thread via bp2008: " You won't be able to pull 12 volts out of the camera, but you could use a passive injector/splitter combo to send 12 volts down 4 of the wires while PoE power + data goes down the other 4 wires. I'm using this one myself for exactly...

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    Ah crud, wish I had taken a picture for you. I am using a 5 amp 12VDC power supply, not POE. So, I used a single 2.1mm power connector and fed it into a DC power splitter which provided me with two DC power connectors up on the tower (I can't recall if the splitter came with the camera or the DC...

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    Today I finally got around to installing my new Speed Dome (SD49225-HN). It replaced a "Dead Dome" that lasted about two years before it succumbed to some kind of IP interface / hardware issue. The Dahua is obviously heavier and bigger than the Dead Dome, which translates to better quality as...

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    Hey @Solar Deity - Just wanted to say thanks for the solid info. I used the products you listed and they work really great for my SD49225. The camera is still in the shop awaiting final install as I just got the mic and other parts in to test. So nice to hear clean, no hum audio from this...

    Thanks very much guys for the replies and feedback. Guess I am just used to quiet cameras and was a bit concerned when I heard this thing making all the noise. Sure appreciate the help !

    Here is a brief video of my Dahua making some noises, first some tilts then some pans.

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    Hey, thanks guys. I wrote Andy and he basically said the same two things. He said the noise (mostly) goes away after some use and not to worry about removing the screws. He reminded me the warranty is good for 12 months. So I'll have a look to make sure nothing jammed up and hope for the best...

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    Thanks for the help Tinman. I haven't opened up the camera (would prefer to hear from Andy first), but otherwise the camera head seems to move easily. I think I'll try to take a short video clip in the next day or two and put it on here to see what you guys think.

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    Great advice wxman. I tried a 5 amp power supply, still no joy. Thank you for the help. I tried contacting Andy here, but no reply. So I sent a message via AliEXpress. I would expect a fully functioning camera just as they expected I pay the full asking price. So before I start screwing around...

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    Hey @EMPIRETECANDY - any chance you're around and can advise if the noise is a normal function of a SD49225T-HN?? The noise is loud enough it's not going to work for my application.

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    Good question Tinman, sorry I left out that detail. I am using a 2 amp, 12VDC power supply plugged directly into the camera.

    Yes, I removed the single piece of from across the front of the lens area. The pan function doesn't squeal, only the tilt?

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    I too just received a SD49225T-HN from Andy at Empire (fast shipping, thanks). Just now powered it up in the shop for testing and noticed the tilt function creates an obnoxious squeal. Anyone else get this??? The noise would most certainly draw attention from people during quiet nights.

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    I had this same thing happen to another brand of speed dome. The camera was about 2 years old when I first noticed the problem. AT first I thought it was a LAN issue, as the camera went through a switch before the router, etc. Then I thought maybe some of the network setting of the camera were...

    Hey Ck - Thanks for the info. Goes to show my ignorance and not thinking it through (although it does beg the question why they force a choice). Anyway, I'm off to go make an order now - very much appreciated !

    Network problem or overheating camera?

    It is somewhat common for a low end camera to succumb to high ambient temps, but I don't think it would fail due to the sun being in the FOV.

    Network problem or overheating camera?

    What was the measured high temp in the nest box and what is the measured high temp inside the house?

    Thanks for your knowledgeable reply wxman, that helps a lot. As we can find searching the forum, sometimes a re-branded camera is nothing like the OEM so your advice puts to rest my concern.
