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...

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...

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...

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...

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...

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 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...

I have a pair of IPC-HDW4431C-A bought directly from China in 2016 with english firmware. They have different lenses and their firmware might be slightly different. The one in question has firmware 2.420.0000.17.R, build : 2016-03-13. I've configured my router to allow the cameras to connect...

I picked up something today (yes, I bought 2 cameras today) called a Vstarcam G96 (also for $30 CAD). It has no ethernet port. It's kind cool - it has bidirectional audio (build-in speaker) and SD card slot. When it's powered up it acts like an open wifi access point. So I connect to it, and...

I picked up something called a Swann SW-Viewcam today (for $30 CAD) from a local retailer that sells a lot of "refurbished" electronics. The camera is spec'd at 720P and it looks like the older D-Link DCS-9XX cameras. It has an SD-card slot (which is nice). I see that it is referred to by...

As someone who owns a few english 4431 and has seen them record video's of trespassers in the middle of the night, I have mixed feelings about the desire for low-light performance (ie - the real value of B/W recordings of intruders / thieves). Color gives so much more info (makes faces more...

The camera in question is a 4 mp Starlight / EXIR DS-2CD3346DWD-I. It's a turret. I'm showing a photo of the main board inside the camera. This is obviously a China-only camera. I can find no listing on the Hikvision english website for this camera (out of curiousity - is this camera offered...

First let me say that putzing with NVR's is new to me - specifically NVR's that are capable of communication with IP cameras that is. I recently played around for the first time with such an NVR (Hikvision DS-7208HUHI-K1) and managed to connect a couple of Dahau cameras to it using Onvif. One...

I've experienced instances where I give my FF browser the URL for a camtalk thread and I get the circlling thing on the tab, with the word "connecting" and it stays like that until I close the tab. Or I'm at the top level of a sub-group and can see all the threads, I click on one and again I...

A friend of mine bought what looks like a Chinese-language DS-2CD3346DWD-I and I've been trying to log into the thing (which I thought I did but maybe not) and see if there's a way to change the language to English. I did a search here on IPcamtalk for 2CD3346 but nothing came up (no mention of...

I have an older Dahau 4431C-A which I can get working with Onvif device manager (and Hikvision NVR) but I can't get live video stream from a new 4433R-ZS. Onvif device manager can see the camera, show the Identification, Time Settings, Network settings, etc, it can show a thumbnail still...

Correct me if I'm wrong, but with the Dahau 4-camera (and maybe also the 8-camera) DVR's only seem to have dedicated RJ45 ports for each camera if the DVR is a POE model. In other words, non-POE models have only a single network RJ45 port, which means they access all cameras over a single...

What does the "HS" give you when looking at a 4104 HS-4KS2 vs 4104 4KS2? Is it just the size of the box? Nothing else? Also, what's the difference between, say, a 2104 HS-S2 and a 4104 HS-4KS2?

I have a 4431C-A camera (bought from china with english firmware version date 2016/03/13) and I'm wondering how (or if) the camera can send more frequent emails during short-duration motion-detection events. There seems to be 2 primary settings for this - Anti-dither and Record-delay (if there...

I see that the ebay price (in CAD) for the HDBW4431R-ZS (4 MP) is about $120, while the HDW5231R-Z (2 MP) is $270. Why would a 2 MP camera be more expensive than a 4 MP? Both are motorized varifocal, the 4431 has SD slot (I don't think the 5231 does). The 4431 is dome (this is a drawback, I...

I'm trying to figure out how to decode the model numbers on the 44xx line of Dahau cameras, and if certain combination of model sequences actually exist. So for starters, the model will begin with either (a) or (b) where (a) DH-IPC-HDBW (b) DH-IPC-HDW (c) DH-IPC-HFW So right off the...

Seems that when you order these Dahua 4 mp cameras that you have to specify a particular lens. I'm wondering why Dahua doesn't even show these lenses as accessories similar to the various camera mounts. These lenses can't be too expensive - maybe $10 each? Why doesn't someone sell a 3 lens...

My idea of a perfect security setup for home (outside, driveway, etc) is to have a receiver that can detect a cellphone that comes into range (because even teen-age theives carry around their phones all the time). Ideally, the receiver could pick up on the IEMI number broadcast periodically by...

All these NVR's are similar (white plastic box): DH-NVR4108 / DH-NVR4104 NVR4108-P / NVR4104-P DH-NVR1104-P NVR1108-P Some are 4 channel (4 camera) and some are 8 (the last number in the model number). What I don't understand is, some have "DH" in the model name (and some don't)...
