    adding 1-way audio

    I'm thinking of adding another cheap 5MP ONVIF camera to my hodgepodge system but this time I'd like to get one with a built-in mic and audio board. I'm not expecting good sound quality, just something good enough to indicate that there are people present in a certain restricted area. My...

    linking two NVRs via Ethernet

    That's a fresh idea. Hearing it made me review my reasons for having NVRs in two locations. Also made me review why not just have a single NVR? Definitely, merging these two little standalone systems would make them simpler and solve the technical issues but there would be a list of...

    linking two NVRs via Ethernet

    Thx for the reply, though I'm sorry to hear it confirmed. If all I can get is live view then I won't go ahead with the idea.

    linking two NVRs via Ethernet

    Sorry for the naive question. I have two small systems where the POE switches are about 70 meters apart. It would be really helpful if I could view the cameras (live & playback) on NVR 2 from NVR 1. I know that if I added a PC to the LAN then I could do everything I want with CMS, but that...

    using Blue Iris to play back from hardware NVR on the same LAN

    My Dahua NVR had a perfect mouse wheel zoom feature (big Plus). It did not support manual snapshots in Playback mode (big Minus). Then, for several reasons, I switched to a generic ONVIF NVR. It doesn't support manual snapshots in live view or in playback. (bigger Minus). And the digital zoom...

    using Blue Iris to play back from hardware NVR on the same LAN

    I can see that BI is amazingly feature rich, but far beyond my needs. Not to mention that the cameras are all outdoors and there's cats and dogs everywhere. Mainly I don't want to load down my two desktop PC's nor add a third one.

    using Blue Iris to play back from hardware NVR on the same LAN

    Thank you for the quick reply, though I'm sorry to hear it. BI seems to have a lot to offer but I won't use it to record. Oh well, I'm stuck with CMS to do manual snapshots and mouse wheel zooming. Too bad CMS 3.0.0 still looks like it's written for DOS.

    using Blue Iris to play back from hardware NVR on the same LAN

    Blue Iris has some features (e.g. mouse wheel zoom) that are missing from my hardware NVR. I have been able to connect Blue Iris to live view each of the cameras via the NVR (not directly via the LAN) but I can't see how to play back the NVR's hard disk files. This was very easy on CMS but on...

    Smart PSS - how to save zoom mode

    Operator error, I assume : I create a 4-camera view and save it. Exit. Re-start PSS, select that view, and everything has been saved except that each window has reverted to rectangle-select zoom instead of mouse wheel zoom.

    Over decode ability

    I too am pushing the limits of my 4108's decode ability, so I went to 9 cam mode on the display and set all 6 of my cameras to stream S1 instead of M. Then I went to 4 cam display, came back to 9 cam and the NVR had switched some (but not all) of the cams back to main stream. Not following any...

    Bought a used Dahua NVR4108 - Cannot PW reset the camera's

    I have these two cameras for which the written password memo has disappeared. I dunno, maybe the dog ate it. 1 Dahua HFW4431S 4 mp 2 Dahua HFW4431M-I2-V2 4 mp Both of these included the firmware that required a password change during installation. So, it sounds like I need...

    NVR 4208 replacement fan for side unit

    I used 47 ohms. By running a little slower it helped a bit but the whine doesn't come from the fan, it comes from the air exiting via the louvers cut into the left & right sides of the case. In the end, I just got used to it.

    Dahua NVR V.4 new features - any info?

    So far I've got nothin', Steve. There are visible changes to the Playback/Search feature that I don't fully understand and may not be important. There may be a lot more under the hood that I thought others would have noticed. RedFish, thanks for reminding me that SmartPSS has the photo feature...

    Dahua NVR V.4 new features - any info?

    I just installed DH_NVR4XXX-4KS2_MultiLang_V4.001.0000000.1.R.200319.bin. Maybe I missed it: is there a forum topic on this new version? There are some changes to the playback (Search) mode that aren't as intuitive as they should be, and probably a lot else that I haven't noticed. Also, it...

    a great cheap IMX291 3MP camera

    Version C1.0.10.54. I got it from CMS-Client - Network Camera I can't be certain it's the latest, just the latest I could find. Gives me access to every option on the ONVIF cameras that I have used it with.

    a great cheap IMX291 3MP camera

    Connecting directly to cameras via a browser was much easier in 2013. It's such a hassle now, I just use the latest version of CMS.

    a great cheap IMX291 3MP camera

    "...why folks buy this garbage for surveillance is beyond me." Yes, that's apparent. Perhaps you missed the part where I said I only buy listed Dahua products for myself, that this little system was a gift to a neighborhood association that couldn't afford even the 24" Samsung monitor that I...

    a great cheap IMX291 3MP camera

    " Still pics do not tell the entire tale." Yup, that's for sure. "How does a persons face look when moving through video." I haven't changed any of the cameras' default settings except 24hr color. Before I post any video I want to see the effect of cranking back on NR, etc, though even then I...

    a great cheap IMX291 3MP camera

    For my own system I feel the same way, but this installation (NVR, cameras, power/switching box, cabling, labor) was a donation. Besides, the system has no connection to the Internet. Totally air-gapped.

    higher megapixel camera = less coverage?

    Possibility: the vendor supplied a 3.6mm lens that was intended for a larger size sensor.

    Problem with playback(Dahua NVR4108-8P-4KS2)

    I have a bug of the same description in my nvr4108-4K-s2 using the latest firmware. So I'm waiting on Dahua.

    some cameras to be connected to two NVR's

    Hmm. As an experiment, I tried to set one of the cams connected to my Dahua 4108-4Ks2 to record only substream 1. There was no complaint when I clicked on Apply and OK but nothing got recorded. Any suggestions?

    some cameras to be connected to two NVR's

    Just need some reassurance on this: One CCTV setup: four cameras on a simple Ethernet switch recorded by a generic NVR. Another CCTV setup nearby: five cameras on a Dahua NVR. I plan to run about 60 meters of Ethernet connecting the two switches. I will set the Dahua to view the primary...

    NVR4108-8P-4KS2 delay when switching camera streams?

    I have the same NVR w/o the POE ports. Most of the cameras are Dahua 3 or 4 MP. The only lag I see when switching views is the one cheap ONVIF cam. Very slow to appear, maybe 4 seconds.
