    How to select playback point on time-line (in-camera recording playback) HDW2431T ?

    During playback of in-camera recordings, I can select a day from the calendar to see when recordings were made that day, recordings are indicated on the time-line. I can hit play, and the recordings are played back one after the other. But I can't seem to use the mouse to select a particular...

    What are my choices for fully-functional web browsers for Dahua cameras these days?

    I didn't think it was possible to upgrade these chinese-market dahua cameras that had english firmware hacked into them prior to sale without risking bricking them. Either that, or there isin't any actual english firmware available for some of these models. Am I wrong about this?

    How to access camera Dahua archives now that IE is dead?

    Just a quick question regarding this web-browser issue - do Hikvision cameras have the same issue - that you need to use IE to work with them?

    Has anyone built their own IR illumination solution from discrete LED's or modules?

    At the end of january I ordered what is known as an "LED COB Chip Light IR" from ebay. These are arrays of LED's mounted on a backing plate. They come as small as 3 x 3 LED's up to I think 10 x 10. What I got were advertised as 30 Watt (3 lines of 10 LED's). They were about $20 each, I got...

    Can someone explain anti-dither and Record Delay settings?

    My camera (2431T-AS-S2 ) has anti-dither and recording delay - no other time-related settings for video detection. Anti-dither is set to 2, recording delay is the minumum (10). Looking at some recent lightning detections, all recordings are about 15 or 16 seconds in length, with 3 seconds of...

    Can someone explain anti-dither and Record Delay settings?

    I'm just going to keep trying the basic video detection. What I've discovered is that I seem to have to set the sensitivity to 100% and the threshold to 10% to capture someone walking in the red zone. The camera is about 15 feet from ground level, and the distance involved in the path beside the...

    Can someone explain anti-dither and Record Delay settings?

    Here's what it did capture today: But it did not capture when I was using the snow blower (in the central area of the image, the parking lot). Here is the zone detection pattern: The red zone detection threashold is set a little bit more sensitive than the yellow zone. Red zone...

    Can someone explain anti-dither and Record Delay settings?

    No NVR. Camera has SD card. Simple zone-based video detection only. Camera will send me email and will record to SD card when video detection is triggered. When I had the camera's IR light on at night, the camera records way way way too many little zippy things, rain, snow, etc. I now have...

    Can someone explain anti-dither and Record Delay settings?

    I see that if I move the mouse over the Smart-plan lightbulb icon, the word "IVS" appears in a box under the lightbulb icon, to tell me (I guess) that Smart Plan must be controlling (enabling?) IVS rules. If I click the light-bulb, I can make it turn orange, or grey. I guess orange is for On...

    Can someone explain anti-dither and Record Delay settings?

    I have no rules set up in the IVS menu. How can you turn "Smart Plan" on if there are no IVS rules? Or does Smart Plan NOT pertain to IVS rules (and if it doesn't, then what does it pertain to ?)

    Can someone explain anti-dither and Record Delay settings?

    The camera is a HDW2431T-AS-S2. I have some video detection zones set up, and had recently set the detection period to all day, every day (instead of just the evening / overnight). The camera overlooks a parking lot, and it does capture when some external IR cameras turn on and off. In the...

    What are my choices for fully-functional web browsers for Dahua cameras these days?

    I thought that these Dahua cameras only stream live video to a browser using an activex control. When I hit one of those cameras with FF, I get a big black screen where the video should be, with a message "please click here to download and install the plugin". It's a link to "webplugin.exe"...

    What are my choices for fully-functional web browsers for Dahua cameras these days?

    Yes, I saw the task scheduler items when I ran Sys Internals AutoRuns and I nuked them there. But this is just a heads up that if you do a fresh install of Win-10 2022-H2 you'll still have IE11 on it and if you're careful during the install, if you work with the machine while it doesn't have an...

    What are my choices for fully-functional web browsers for Dahua cameras these days?

    A few months ago I picked up some refurbished HP Slim desktop PC's that came pre-installed with Win-10 home. They had 4 gb ram and a 1 tb conventional hard drive. Came with a new keyboard and mouse. They couldn't have been much more than a year old. $170 (CAD) each. I upped the ram to 8 gb...

    What are my choices for fully-functional web browsers for Dahua cameras these days?

    I currently have a few HDW4431C-A and HDW2431T-AS-S2 cameras that are now 5-ish years old but working well. I have them set up to do in-camera detection and send email with photo when they detect something. When I want to change their setup or watch them in real time, I have a couple of handy...

    Cameras are here but nothing works, what am I doing wrong?

    Default. Go to Wikipedia and after the definition of 'default - computer science' it says: "Default values are standards values that are universal to all instances of the device or model and intended to make the device as accessible as possible "out of the box" without necessitating a lengthy...

    Cameras are here but nothing works, what am I doing wrong?

    So why have a default ip address, 192.168.1.108, impossible for most of us who are not network savvy to get to as a default address?

    Has anyone built their own IR illumination solution from discrete LED's or modules?

    My post here is about IR LED's and lighting strategies. For years I've tried to get away with placing a few cameras in windows, and you realize that you can't use the camera's own IR light when you do that, so you look for external IR lights. What I've found on ebay are advertised as 10 (or...

    Is it possible to enable/disable In-camera event detection through external command (http, onvif, etc) ?

    Is it possible to enable/disable In-camera event detection through external command (http, onvif, etc) ?

    I have a Raspberry that I could configure to monitor the status of my old alarm system so it would know when the alarm is enabled or disabled. What I'd really like to do then is have the Pi send a command to my Dahua cameras to enable or disable their in-camera event detection based on whether...

    Face Detection, IVS, Heat Map, Smart Plan Setup Questions

    So if I want the only available IVS functions I have (intrusion and tripwire) to work, I have to "turn on the light bulb"? Should I have a "global settings" tab beside the IVS rule config tab? Or maybe I don't because of limited IVS functions I have?

    Face Detection, IVS, Heat Map, Smart Plan Setup Questions

    I don't get it. My "Smart Plan" menu just has a single large button / icon (the light bulb). No other buttons (not even any grey'd out buttons). So I have no idea what turning on the "light bulb" (ie making it orange) and then hitting "apply" is supposed to do.

    Face Detection, IVS, Heat Map, Smart Plan Setup Questions

    Why is it that when I buy a pair of Dahua cameras - with different lenses - one has IVS and the other doesn't?

    Yes, thank you. Disabling the smartcodec did activate the IVS menu options in the web interface.

    Why is it that when I buy a pair of Dahua cameras - with different lenses - one has IVS and the other doesn't?

    Back in 2016 I bought a pair of 4mp turret Dahua cameras. I think they were 4431, China-market with hacked firmware. They were identical except one had 2.8mm lens, the other had 3.6 mm lens. When I got them I found that one had all the various IVS detection features, the other didn't. Fast...

    A few basic questions about IR lights

    A few years ago when I bought some 4k Dahua cameras direct from China I also bought some IR lights. The housings were half-spherical, about 2 or 3 inches in diameter, some had a face full of small regular-sized LED's, others had 4 high-power led's with lens in front of them. Both types of...

    Dahua's Main Competitor Is... Dahua!

    I've got a few IPC-HDW4431C-A that are about 3.5 years old now and they get the job done. I'm sort-of in the market for a few more cams - I'm curious about this "active deterrence" thing - what is it, how does it work? Also, are there any cheap 2 to 4 mp cameras that have IR motion-sensor...
