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 is also allocated in the router for same
- Using BI as my usual viewing app, but the signal goes away using the software supplied with the camera (can't recall the name of it)

Anyone else have this issue with a new Dahua PTZ? I've had one other camera that lost connectivity like this, but shortly thereafter it just died. :(
Do you have UPNP turned off in the cam?

Do you have the cam blocked from accessing the internet?

Any ports forwarded?

Thanks for the replies and suggestions guys. Sorry for absence, was out of town again.

Of course after multiple failures and checking everything twice, only then did I post the message here about the failures. The camera has now run a day and a half without failing. I'm hoping it was just some fluke, guess I'll see. Maybe Murphy has a good brother?

You guys are great, always so helpful.

///////////////////////////////////////
even tho you tested the cat5 try another cable -
The cable runs up a radio tower so there's no practical way to replace it. Instead I put another cam on the end to see if it would lose connectivity, and it did not. When I plugged the Dahua back in, the problem occurred again.

also try another power supply -
I didn't try another power supply but I have checked the voltage and current using a VOM and it looked fine.
///////////////////////////////////////

Just curious, does it lose connection both day and night or only during the day? Trying to rule out overheating.
This was my initial main concern because I have another PTZ that fails religiously at 85 degrees (I literally unplug the cat 5 from it when it gets above 80 degrees around here, which is everyday now). Thankfully, a few failures have occurred late at night, <65f.

I'll have to check, I haven't fiddled with any of the default settings - except the frame rate which I lowered a bit.

Hmmm, good question. If you mean in my router settings, then no. If it's a camera setting? then I'd have to check - but again they are default except as stated.

Any ports forwarded?
No ports forwarded

Yes thanks, 'looney' shared the same info. I bought them off eBay too, amazon wanted 5 bucks for shipping. I just need to climb up to the camera and install one.

I took a quick video of the one I received with the broken tilt mechanism.

It has been sent back and I'm waiting on the replacement

The noise normally can be back to normal when the cam pan/tilt for some days. I think one of the dessicant pebbles got in the gear, i ask SD to help me checking the returns one he manually fix this one up. So sorry for this, i will send you a new one and with adapter, I will test it tomorrow myself and make it shipping~ Will help you sort this out, no worry.

I'm very happy with performance of this camera in the back of our house. We have a dirt road that runs through our property behind our house. It is very dark on that road at night. In the past I've used 3 other cameras to monitor the road. The captures I got from the other cameras were not very good at night. Here is a screen capture from last night. From the moment he walked into the frame he was staring directly at the camera. He did look down a couple times but as he walked out of the frame he was still looking at the camera. I'm pretty sure he knew it was a camera. In this capture he is about 90 feet (27 meters) away from the camera. About 25 minutes later he was captured again walking back in the direction he came from.

Nice pic lulu5kamz! Can you tell me how visible the LEDs are when someone in the dark looks at the camera? Do you think they notice it?

The fact that he was looking directly at the camera (that whole side of the house was dark at the time) before walking into the frame and still looking at it as he walked out of the frame tells he saw the lights from the camera even at that distance (there were 6 LED red lights illuminated for this zoom level). While I have not been down there at that time of night, I'm guessing the lights must be visible even before walking into the frame.

I do have the whole 9 second capture, but this site doesn't allow mp4 file uploads. Also, I don't want to put this on my YouTube channel so you might be out of luck unless someone can suggest an alternative upload method (the file is only 5.97 MB).

Edit: I did try uploading both the MP4 and AVI version of the file to TinyPic, but neither file was able to be processed. I ended up getting an error for both.

Just create another YouTube channel within your account. I also did this for sample footage.

So far my Dahua Starlight has been working great. It's pretty obvious why it's named "Starlight". I live in a rural area, and any moonlight at all makes the night look more like day. Seeing the stars is cool too.

Nice scene! Are you in manual exposure with the shutter maxed to 1/3 (or 1 second as it says on the user interface, but is actually 1/3)? If not, that could make it look even clearer/brighter.

Also, have you tried it in day/color mode at night with slow shutter? Seems like you could get a decent night color image with that scene, especially in moonlight.

Hey, thanks for the tips wxman. I'm still fooling with the default settings of all things, but I will be experimenting with the additional features.

Hi everyone, I'm very interested in these dahua turrets. After discovering that dahua and amcrest cameras are the same, and seeing the excellent night vision quality of dahua, I'm nearly sold. I'm coming from Amcrest cameras IP3M-943 1296P 3MP cameras and some IP2M-841 dome. I own 3 myself and I installed 5 IP3M-943 for my dad.

I have a new house on the way and I had the builder install five RJ45 jacks on the outside of the house for me for POE cameras. You can see the picture I attach which shows one of these outdoor POE ports, this one in particular is for the front door overhang. All the ethernet ports will run up the house into the master bedroom closet where the structured media enclosure is. That is where all the network and tv cables come into the house.

I have some questions regarding using the Dahua cameras:

1) Do these Dahua cameras have an iPhone or iPad app similar to the Amcrest View Pro so that I can install an iPad screen in my house and visualize all the cameras live? Basically, I want to be able to have "Live View" feature. Does Dahua cameras have it?

2) My new house is going to be wired with RJ45 Cat5, they couldn't do cat6 for me. Does CAT5 cable support POE+ (plus) which is the 25W one? So all I have to do is buy a POE+ switch that can do POE+ right?

3) Does the Dahua camera (turret version) support FTP file transfer, record on motion, port forwarding ? (basically everything the Amcrest allows) ?

4) So the only cable I need to run for the Dahua 2MP starlight is just the RJ45 cable right? And I would inject the POE through it.

Currently, I am using a Raspberry Pi with a 64GB SD card. All cameras are FTP'ing into the Raspberry Pi and uploading the video there. For my new home, I intend to buy a WD NAS 4TB drive and just have the cameras NFS into this thing. Does the Dahua cameras support NFS video upload? I will then use the Raspberry Pi to periodically monitor disk usage and erase the files with a daemon script running in the background.

Thanks!

I just verified that the Dahua app does indeed connect to my Amcrest camera! That is sweet. That means I can have a mix of Dahua and Amcrest cameras all use the Dahua app.

Also, it doesn't appear that the Dahua app has Push notifications like the Amcrest has. That is a major bummer for Dahua.
