Those who are familiar with Dahua's WDR settings will know that the higher end cameras equipped with True WDR (120db and up) are only True WDR when set from 45% and upwards. With WDR on and set to anything below 45% it uses only DWDR - that being software based by only adjusting the gamma and...

I have just replaced my XVR with an NVR and have setup all my IP cams to send alerts on SMD human motion detection. I am now having issues with my push notifications on iPhone. On my previous system it worked perfectly: SmartMotion Human, Camera Name Now with the new system the push...

Hi, I have a 2mp Dahua PTZ, that has been brilliant since 2019. However, recently, the past 2 or so months I have noticed a strange constant pixelation / noise at the bottom of the screen. It is there constantly. Whether there is movement in the scene or a still scene, change of light, shadows...

I am running a hybrid system of 16 cams (11 WizMind IP cams and 5 HDCVI cams) currently all connected to a XVR (DH-XVR5216-4KL-I2) The XVR gives the HDCVI cams WizSense AI but I cannot recored on SMD for the IPs or get push notifications for any AI alerts through the XVR. Only solution is to...

I am looking at replacing one of my older 2mp cameras that face the street with either the 4mp HFW5442E-ZE (IPC-HFW5442E-ZE) or the 2mp HFW5241E-ZE (IPC-HFW5241E-ZE) - both with WizMind AI Between these two camera, which one performs better in low light / at night, and produces a better quality...

Hi, I have a Dahua XVR and Dahua cams both IP and HDCVI. I am looking at some Axis IP domes on the remaining slots I have available on the system. Does anyone know exactly how much functionality will be lost on the Axis cameras going through the Dahua XVR? Is it still worth it? Would I still...

Hi, I see Dahua have released a new update of SmartPSS for MacOS Catalina dated 14 April 2020. Has anyone updated and tried this version yet? Is it stable? The December release was not and was very resource heavy. The new release is available here...

I am sure this topic has been discussed a few times here, but would like to know what most think the best practise is for syncing Dahua IP cameras' time with a Dahua NVR/XVR's time? Should the NVR/XVR be set to sync with an NTP and each IP camera also set to sync with an NTP in the camera's own...

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...

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...

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...

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...

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?

I am sure this topic has been discussed before, but could not find any previous posts here. Security industry white-papers and professional installers both make their cases for either CBR or VBR to record video files. So storage space and bandwidth aside, I am interested to hear your thoughts...

Dahua cameras with defog capabilities have this function set off as the default. With cameras that support this feature, are there any known disadvantages / compromises should the defog be active?

I have noticed with HLC on, super bright areas or light sources in the scene get blacked out (for example car headlights that are blacked out), however I have seen footage where HLC does not do this, it simply dims the light source in the scene. Is this possible to adjust to achieve this?

Hi, I am currently running RG59 coax cable for 9 Dahua Ultra series 2MP starlight cams. They are great cams! I am starting to pick up video signal issues (loss of signal, ground loop looking interference such as rolling lines etc) due to some of the cables that run under ground in conduit most...

Hi, I have a couple of the Dahua Ultra Series HAC-HFW3231E-Z cameras. In the camera's OSD's "Main Menu" under "Exposure" there are the following menu items: Exposure Mode. I have set it to "Auto" and then turned "Low motion blur" on (this should in fact increase the shutter speed if I am not...
