Best Setting for Motion Detect Record
I do. Thing is this is for a PTZ. So to record on tripwire will be a bit difficult as the area is large and the scenes can change. All the other cams I record 24/7 both on regular and motion and have IVS setup in some cases. But for this cam I want to just record on motion, not too concerned on... -
Best Setting for Motion Detect Record
Been playing around with it too, can't figure it out exactly. Doesn't really seem to do what the Dahua definition states, I read theirs up on the Wiki too and then found other descriptions from other manufacturers which differed. -
Best Setting for Motion Detect Record
Googling "anti-dither" and "latch" in security camera terms can be a bit confusing... seems the explanation and definition of these terms varies and not all that clear. Dahua's default settings for Motion Detect is anti-dither set at 5 seconds and latch set at 10 seconds as well as delay at 10... -
Dahua / Hikvision Banned?
In addition Dahua and Hikvision sanctioned for Human Rights abuses: Hikvision And Dahua Sanctioned For Human Rights Abuses And also according to IPVM, Dahua and Hikvision have been kicked out of Onvif? ONVIF Suspends Dahua and Hikvision Anyone know what the implications will be?- ermac

Night vision settings for Dahua PTZ
Cool, thanks jmcu for sharing your experience with PTZs and plates, makes sense. And thanks for the tip on the HLC and day/night settings. Do you know what the difference is between the "Smart IR" and "ZoomPrio" mode under the IR setting is? -
Night vision settings for Dahua PTZ
Hi, I would like some recommendations for adjusting my PTZ's night vision. I have a SD49225T-HN. Currently all running on default settings. Daytime images are fine, it's the night vision that I want to sort out. My main issues is that reflective number plates are over exposed by the IR light... -
Intermittent streaming of main channel
Have you run a ping test from your PC to the camera yet? -
Packet loss, jittery image at times
Just an update and interesting observation. So before I started unplugging cables and start the troubleshooting, I shutdown the XVR completely and then pinged the camera from the switch in the office. No packet loss! and sub 1ms ping times. Also very consistent. I think it is safe to say that... -
Packet loss, jittery image at times
@bigredfish I think you have the 4MP or 8MP 7216A model, either the 7216A-4M / 7216AN-4M or the 7216A-4KL. Could explain how you can run a bit rate of 8192kbps on the IP channels. My 7216A is the 2MP (1080p) decoder. -
Packet loss, jittery image at times
Just checked out the GS108LP. Would have been a much better choice instead of the GS108P and a PoE+ injector. Also it would have eliminated two connections on the route (the connections going in and out of the PoE+ injector). -
Packet loss, jittery image at times
Thanks for the replies. @SouthernYankee will do the tests as you suggested and see the results. Must be an issue between the Netgear switch and camera, so maybe the PoE+ injector or lightning protector or the cable connections there, because I ran a ping test from the same laptop connected on... -
Packet loss, jittery image at times
I am recording to a Dahua XVR 7216A. Distance between pinging device and camera is approx 62 meters (203 feet). A mix of bought patch cables and installation cable. All the Ubiquity ToughCable Pro installation cable endpoints made by the installer on-site. All connections were tested with a RJ45... -
Packet loss, jittery image at times
Hi, I notice on the live feed from my DH-SD49225T PTZ that it can be a bit jittery on large scenes with fast moving objects. Seems to be less so when the camera is zoomed in on a smaller area. Recorded playback seems to be smooth and so does live view on mobile devices. The DH-SD49225T IP PTZ... -

PTZ Pole Mount Height (SD49225T-HN)
Hi, I want to install a SD49225T-HN IP PTZ on to a pole and was wondering what the recommend height should be for my application. I want to mount the PTZ on a pole next to the driveway, about 1.5m - 2m from the street. Its purpose will be to monitor the street for approaching vehicles around... -
IR Reflection
I have played with the IR settings, does only a little bit to help, still have this massive "spot light" reflecting back into the camera. So instead of adding additional IR illuminators, and as it is a starlight camera, I have turned the IR off so it is running in starlight mode / full colour at... -
IR Reflection
Ok I will see what I can do regarding additional IR lamps. In the meantime, will playing around with the smart IR setting help? -
IR Reflection
A new reflective street sign was installed about 12 meters in front of my camera. It's causing a lot of bright IR reflection in the image at night. Not ideal. Any suggestions on what settings will rectify this with out effecting image quality? -
Out of nowhere my SD49225T-HN looks like it has an HDR filter on it
Hi Zebrock, a similar thing happened before to me on some of my HDCVI cameras. I eventually figured it out, it was the EQ setting. The EQ setting should be on 0. But by default the EQ setting is left "unlocked" so the system can adjust it to like 1 or 2 etc. I solved the issue on the camera in... -
Dahua Starlight+
Thanks for sharing your knowledge dougri. Clearly a lot more to it than just the size of the aperture, novice mistake in judging the specs. -
Dahua Starlight+
Interesting, so the F number is the lens aperture (think of an iris of an eye), the smaller the F number, the bigger the aperture, which allows more light in. The 4MP has a slightly smaller aperture (F1.9) compared to the 2MP with a F1.6 aperture, so the 2MP still has a bigger aperture and could... -
What causes choppy video playback?
I assume you are using H.264+ compression. For 4MP at 30fps: 3086 to 7987 kbps For 4MP at 25fps: 3172 to 6656 kbps At 30fps, 7987 kbps will give you the best picture quality and at 25fps, 6656 kbps will give you the best picture quality. CBR at the higher values will cost storage space. Try... -
IPC-HFW5231E-Z12E Motion Blurr
Not sure why regarding the other camera versus this one Casey. Was the other Z12 a 2mp camera or a 1mp? I definitely think the issue here (from the video you posted) that the encoding bitrate is too low and that's why it is pixelating on the playback. Pixilation like that is either caused by... -
IPC-HFW5231E-Z12E Motion Blurr
Considering you are using that camera to record fast moving objects, i.e cars, and it is a 1080p camera (2mp). 2048kbps is a bit too low (that is usually the optimum setting for 720p (1mp) recordings), you need a lot more Kbits per second to record those moving cars than on a still scene. If you... -
IPC-HFW5231E-Z12E Motion Blurr
Hey Casey, what BPS (bitrate) have you set the encoding at for that camera? (that's not motion blur, that is pixelation due to the bitrate setting set too low, or at least not high enough to give you the best quality on your recording.) -
I cannot find shutter speed adjustment anywhere
Here are pics of some of my ultras on their polls, also about 12'. As mentioned in one of the treads I had started a while back, some are experiencing groundloop issues. Had a technician come out, he suggested I place a non-conductive material between the camera junction-box and the metal pole... -
I cannot find shutter speed adjustment anywhere
Are those cams pole mounted? -
I cannot find shutter speed adjustment anywhere
Love your setup. Like Fort Knox ;) These recordings are all CBR at max bit rate?
