    Tripwires --- ugh, I need help!

    Doesn't Dahua treat multiple active tripwire rules as an "OR" condition (no option to make it an "AND"), and thus the more you have the more false positives you will have? And if the target person, car or bright light spot moves slowly, you will get several triggers from the camera (good or...

    Junction Boxes for Dahua Bullet Cameras,,, can I get smaller

    wouldn't it be nice is the manufactures made most of the models with a base that is 1cm deeper so that one did not need a box if they didn't want one. just say-n.

    Good quality Dahua mini bullet camera

    it mounts fine to 2x 3.5" trim (IMO), with one lip slightly over the edge. I do it all the time. I usual use two of the three screw holes (unless it is in a corner, where i can get all three), using quality 1-5/8 or 2" coated deck screws. I tend to not use the mounting box, witch is a bit...

    2021 New Product From Dahua

    I will be curious about the multi-lens camera. On the surface, it doesn't make sense. I assume that it has two sensors, not just one 1/1.8"? Why would the panoramic and the detail segments use about the same focal length lens vs one being like 3mm (vs both being 8mm) and the other being much...

    Using an IP camera with a video meeting app like Zoom or Jami

    Wyze released a firmware to use their V2 camera as a web camera for this exact reason.

    Dahua CEO resigns

    Thanks for posting that. I suspect that the founder will ease vs exacerbate US government concerns compared to a former Huawei executive.

    THat sounds like a PIR sensor in one area triggering the camera in another.

    IVS Tripwire on Dahua

    The Wiki does not really address any of my above issues. What is needed is more of a best practices. If i get through this, maybe i will write one. Adding to the tripwire mysteries: I have noticed when i do get the setup working that strangely it is far more sensitive/responsive to small...

    IVS Tripwire on Dahua

    Has anyone written up a guide of sorts on IVS Tripwire on Dahua cameras (ex IPC-HFW5231E-Z5)? I seem to struggle to understand the logic. There is a “detection zone”. Should this be used big to the boarder of the frame to allow time for an object to be noticed before the trip lines, unless...

    New Mini PTZ now with 4x zoom SD1A404XB-GNR

    I am curious as to how they got the same low light performance as the previous 2mp 203 models with this new 4Mp version. Since they dont list shutter speed, they might be playing games. They should all be at 1/30s for consistency. They claim 4x optical, but my math says that it is still 3x...

    What causes these ghost images?

    You need either more light on the target for the same shutter time (10x to 100X more, not 2x more) or you need to reduce the shutter time (which will darken the image, so you will need more light anyway). Don't increase the gain. It appears to be in B&W, so simply adding an external IR...

    Does anyone know what gauge wire are used in Dahua cameras?

    I have not measured them, but since i did not see a reply i will take a guess. They are smaller than 16ga. my guess is 22 ga. good luck

    Questions about day/night brightness management (profile)

    3. Assuming windows OS, try to add a static route then click the IE link to the camera. try the below (second line), assuming the NVR camera interface is on 10.1.1.1/24 route ADD destination_network MASK subnet_mask gateway_ip metric_cost route ADD 10.1.1.0 MASK 255.255.255.0 10.1.1.1

    Possible to change zoom on Dahua Starlight IPC-HDW5231-RP-Z with SmartPSS?

    It doesn't work very well, but it works. For some reason it is very buggy. It is in the bottom left of live view, not in settings for some reason (another odd thing). I tend to use the browser interface to zoom.

    tool head broke off in set screw of Starlight Housing

    Did you get it out? It looks like there is just enough thread to use a new set of Vicegrips on the outer threads and unscrew it. I am assuming it is extra tight and hence the reason the torx tip broke. If the Vicegrips do not work, i would drill the inside out (@Tibor Makai ) just enough to...
