    Is a Dahua NVR actually 1U or 2U in a rack?

    Heh, that caught my eye too, but you have a VERY neat and tidy setup there. And Unifi FTW! At least, for everything but cameras. I got my rack last week decommissioned from a business, and it came with a bunch of shelves and PDUs installed… and apparently some genius years ago installed a 1U...

    Is a Dahua NVR actually 1U or 2U in a rack?

    lol, so true. I just unboxed mine to measure. Without the feet - so only the housing - it’s 1.85” thick. I mean… how CLOSE to being able to stick ears on this thing are they? Just shave off 0.15” and we’re good! With feet, it measures 2.06”, which is less than the 2.2” spec, but still more...

    Is a Dahua NVR actually 1U or 2U in a rack?

    Well, they should at least stop using industry standard terms inappropriately! But Ethernet, POE, HDMI, USB, RTSP, ONVIF, h265, ftp, https, the list goes on… there’s a lot of standards-based stuff being used in these NVRs. And the PFH101 shows they are at least passively aware of racking standards.

    Is a Dahua NVR actually 1U or 2U in a rack?

    Definitely looks like it’s 2”. A 1U device can be only 1.75” absolute max, assuming it had ears that could be mounted directly on the sides. (See Unifi switches that are 1.7”). With a shelf requirement, it would have to be thinner, like maybe 1.60”. Dahua should really look at engineering...

    Is a Dahua NVR actually 1U or 2U in a rack?

    Will do! Moved to a new place and it’s my first time doing a proper organized rack. For the last umpteen years I’ve just had various piles of switches and servers, lol.

    Is a Dahua NVR actually 1U or 2U in a rack?

    Well, yeah. Which is why I’m finding it confusing that it’s referred to specifically as a 1U NVR, but then the specs for the model I have (still in box) says it’s 2.2” high. There is also an official rackmount adapter sold for it (but expensive), so it’s not like “1U” could be assumed to refer...

    Is a Dahua NVR actually 1U or 2U in a rack?

    In planning out my network rack, I was checking the size of the shelf I needed to buy... and now I'm confused as to the official specs. It's called a 1U NVR, but 1U is 1.75" high. The official specs say it's 2.2" high. So does it actually end up taking 2U of vertical space sitting on a shelf in...

    Lorex 4K Doorbell

    Good news! The configuration options seem to come up fine in SmartPSS. I was able to bump the UHD encoding bitrate from the default of 2048 to 6144, and change audio from whatever crap codec it was using to AAC, but I can’t seem to change audio bitrate. Can’t remove the Lorex watermark. Does...

    Lorex 4K Doorbell

    Hmm. Haven’t tried SmartPSS (will do that later) but I got it working with DMSS (iOS) on port 35000. It logs in, lets me see the streams (correct aspect ratio, sound, seems like it might allow talking too), view all motion recordings (seemingly a heck of a lot more than the Lorex app gives me)...

    Lorex 4K Doorbell

    I just installed my Lorex 4K doorbell yesterday if anyone has any questions. Previously I had (at a different house) a Ring Pro. Lens/sensor quality seems quite good, but I do wish the bit rate was higher. No adjustments that I can see. Very little lens distortion. would like more than 15...

    How are Dahua doorbells?

    https://www.lorex.com/products/b862-lorex-4k-wired-video-doorbell Quite a bit more spendy than the Reolink 2K.

    How are Dahua doorbells?

    Looks to be US Prime only (I’m in Canada). But they seem to have a coupon going in Canada which brings it down to the equivalent of $88 US.

    How are Dahua doorbells?

    Have to say I’m quite intrigued by the forthcoming Lorex 4K doorbell. Unless the video quality is garbage, it seems to have everything I’m looking for including chime integration, local video storage, no fees, etc. The ReoLink also looks quite good, only I have a real soft spot for mechanical...

    How are Dahua doorbells?

    Ugh. So the Dahua 2K’s video is horrible (and seems to be the only model available). Frankly the Unifi’s video is also completely unacceptable for the high price. And the otherwise excellent Reolink won’t activate a local doorbell chime. Thinking I’m just going to install the old but still NIB...

    How are Dahua doorbells?

    Yeah, sadly POE is not an option as the builder only ran a standard doorbell cable.

    How are Dahua doorbells?

    So, I’m really opposed to monthly fees to view cloud camera feeds and whatnot. I’ve used Dahua for well over a decade now, and everyone’s always amazed the quality and ease of use of my cameras in DMSS. I’m looking to get away from the monthly fees of Ring, and had been considering a Ubiquiti...

    IPC-T5442T-ZE picture issues

    Honestly, the green screenshot looks like whatever I get when I try to view the RTSP feed on my cams - however the native Dahua feeds are perfect, as are recordings. Did you try h265?

    Dahua best cam 2021? (Now 2023!)

    Okay, slight topic shift. My father-in-law had an attempted break in early this morning (only thwarted by a neighbor calling him while it was in progress), and I've finally convinced him he could use some cameras. However, unlike myself where image quality and discreteness is key, here I'm...

    Is my SD49225T-HN dead?

    My SD49225T-HN PTZ seems to have died. My recordings stop at Sunday March 12th, 1:00 AM exactly. There was a weekly reboot scheduled at that time. Prior to that everything with the recordings were fine, no glitches or issues. Currently when I plug the cable in, the PTZ portion goes through the...

    Can you mount to standard electrical boxes?

    Can you mount to standard electrical boxes?

    Is there any way to mount a Dahua turret camera to a standard single gang or 4” round ceiling electrical box (for under soffit mount)? I can’t tell if the PFA130-E can do this or not.

    Dahua best cam 2021? (Now 2023!)

    It’s just hooked up to one of the 5216’s POE ports, which are POE+ rated. I always use quality solid copper CAT6 cable. The ends were re-terminated, but I suppose there could be an issue with the actual run (like a kink or something). I know back in 2018 this particular hardware version...

    Dahua best cam 2021? (Now 2023!)

    Thanks for the advice! I won’t push the resolution then. Probably just upping the bitrate would give me what I’m looking for. I’m currently running an original SD49225T-HN PTZ and the thing has been an utter nightmare. Constantly locking up and requiring the power pulled through years of...

    Dahua best cam 2021? (Now 2023!)

    Thanks! But also, ugh. Preferred just to get whatever the current version of the 5216 was - but it seems like they’re all 2-3X or more expensive? I guess I’ll standardize on 5442’s around the house as I do know they work well in zero light, although I find their daytime HDR sometimes a bit...

    Dahua best cam 2021? (Now 2023!)

    Three quick questions: How's the T5842 versus the T5442? I saw a review comparing these and the sharpness seems stellar, and night IR performance... similar? Though it's hard to tell. For these cams, are there ever feature differences between the vari-focal and fixed lens versions? The price...

    Dahua best cam 2021? (Now 2023!)

    Is there a reason why those cameras are choosing to use visible light illumination instead of IR? It seems a bit weird that my cameras would be constantly illuminating my exterior all night long.

    Dahua best cam 2021? (Now 2023!)

    So, the 4K model definitely requires ambient light? The house is in a new rural development on largish lots, and I’m not sure there will be streetlights. Lots of moonlight, though, since there’s like zero trees around. I’m happy with the 5442, but you can never have too much resolution. The...

    Dahua best cam 2021? (Now 2023!)

    So, it's 2023 now - and I'm moving to a new house, so it's time for an all-new camera system! Two years ago I added two of the IPC-T5442TM-AS to my system and they've been doing very well (although I think the microphone quality was better on the HDW5231R-ZE). But I'm looking to see what...

    Dahua SmartPSS Crashing in Windows 10

    Good call on that one! Brand new Asus Z690 Hero setup in Windows 11 and after a clean, fresh SmartPSS installation with zero customization besides adding my NVR, it would crash instantly on live view if software decoding was selected, and after 5-10 seconds with hardware decoding selected. I...

    IPC-HDW2231R-ZS IPC-HX2X3X-Rhea_MultiLang_PN_Stream2_V2.800.0000013.0.R.191202.zip

    It’s a NVR5216-16P-4KS2E (2018). Previous firmware I had on these cams showed the correct model, and it does so for 4 other different Dahua models I’m using. (All with firmware updated yesterday). I’ve seen this before on this and at least one or two other models, and I thought it was more...
