I am trying to figure out / tune two of my front cameras with regards to motion triggers using AI. Most of the settings are under each camera Trigger/motions sensor/configure. I think this issue is common, applying to many people’s BI-AI setups. There are a few things that I haven’t been able...

I am in a death spiral on my BI 5 computer. It stopped getting trigger captures about 6 weeks ago. I restarted the machine and then I realized that the BI version was 6 months old, but I was unable to update it due to expiration of update (part of support). So I wasted $35 on a BI update that...

I try to largely leave thigs alone that are working, but perhaps i have been asleep at the wheel over the last couple of months and didn't notice some stuff changing in the BI/ DS world. Today, i tried to see what went on on one of my cameras early this morning/late last night, and was stymied...

I just tried exporting a short clip from BI (latest 5.5.7.8 x64). Both live and snapshot playback are fairly smooth (10fps) on the server (headless) with low CPU (<35%), However, if i try to play the mp4 file locally or on another laptop, it stutters quite a bit. see attached file.

My best camera, the Ultra Starlight HW8232EP-Z, is dying or is nearly dead. It is off line for most of the time, only powering on for about 8 to 10 seconds every 2 minutes or so. I thought that it was the RJ45 female oxidized and weak pins force, so after failing to get better with some...

I seem to be too dense to figure out a simple back and forth recorded viewing option in BI. I would appreciate a bit of help with this trivial issue. example: Lets say i expand the time line below the real time all cameras live view (green clock icon). If i want to look at one feed from the...

I need a bit of help with regards to BI Clips and Archiving setup, mainly dealing with New and Alerts. I am using DeepStack as a trigger. I have my cameras all setup as dual stream (main and sub D1), and use direct-to-disk. Does this mean that I should be creating two file sets in the “New”...

I am slowly ramping up my BI + DeepStack game. I added dogs and cats to my objects (and removed cars and buses from my indoor cameras). One odd thing is about 70% of the motions made by my dog are flagged as CAT, and about 70% of the motions made by my two cats are flagged as DOG. It is...

I have one Hikvision camera from a few years back (DS-2CD2142FWD-IS) that i want to bring its firmware more up to date, now that i am implementing Blue Iris as an NVR. I found the latest HIkvision provided firmware on their site and downloaded and expanded the zip file on my laptop, but when i...

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...

Did some version of firmware improve the hysteresis / light sensitivity switching (BW to color) of the IPC-HDW5231R-Z? I ran across this last year. I "fixed it" by going to all color with a bit of extra light. I no loner want to leave the light on in that location. I had forgotten how bad...

I am thinking of installing a motion light system in my large open office space. The primarily goal is to encourage a perpetrator of a window break in attempt to chose to exit vs grab. I will gladly eat the cost of a window vs losing stuff. The secondary goal would be to increase pixels on...

Does anyone have a good feel for the light output per LED at some useful distance as it relates to camera shutter speed? I am not sure that LUX is a good measure at 850nm, as I expect that the camera is way more sensitive to 850nm than to visible light of the same lux rating (just a guess), but...

Has anyone found a good solution to a professional video doorbell for a small business? GRANDSTREAM IP Video Door System seems promising at first glance, but others don’t seem to like it. As far as I know we are still suck with the Ring lineup, which is decent for various situations, but does...

It appears that my DH-IPC-HFW5231E-Z5 does not support a 90 (or 270) flip to corridor mode. Am i missing something, or is this a feature drop? Flip mode 1 and 2 fail and in the browser interface i only see 0 and 180). The data sheet shows 90 and 270 however, and it is the same firmware as...

Does anyone know what the setting in the Dahua encode section of Smart Code "open" vs "closed" does? Isn't H265 already a smart codec?

How does the Dahua H.265 series fit in the mix of ecosavy 3.0 and lite series? They all support H.265?

Is there a decent way to use a remote of some sort to go between 2 or three presets on a Dahua camera? I am up for trying almost anything, so long as the end result is fairly clean and robust. Thoughts are programmable RF remote to a IP gateway, cell phone app, wall buttons with or without...

I am just starting to set up BI. I think i am missing something very obvious in the setup process. I think it is not recording 24/7 (direct to disk). It is however recording clips. It is also generating files in the "new" directory. The reason i think it is not recording, is two fold...

I am still dragging my feet in my home setup NVR. For one thing i figured that memory prices would come back down, but they have not, and another thing the availability of low priced I7 6700s is poor, likely due to the prevalence of laptops in the workplace now. As i look into this move again...

I have wondered for quite a while why the IPVM forum site is so expensive at its lowest price tier. I would think that many times as many people would subscribe to a forum that had person service prices that were a fraction as high. Who can justify $200/year besides a successful multi-person...

Has anyone tried running BI on the i7 NUC with either an external USB-C Thunderbolt or SATA drive (open case) connection, with the OS on the internal M.2? I would think that it would work pretty well. Not really cheaper, but smaller...

This is probably a dumb question, but i just stated messing with the Dahua NVR5216-4KS2 that i put in our small office. How do i review the video remotely in high speed? I can use the web interface, and i discovered that I can add it a device in SpartPSS 2, where it shows up as a device type...

I am confused about what is happening to the pixels and bit rate when i display live feeds. If i run something like SmartPSS on my computer (ex main stream) from one camera full screen on a 1080P monitor, i see a bit rate (ex 1900 kbps) and a resolution of 1080P. when i reduce it to 1/4...

I hope someone can help shed some light on this for me. I do not understand why the lens range and the zoom range are so far off, according to Dahua's data sheets. For example, for the DH-IPC-HFW5231E-Z5, i see that the zoom range is from 7mm to 35mm (5 to 1), but the actual zoo is from 35...

I am wanting to set up a couple of cameras in corridor mode in a small office (indoor). Does anyone here have experience with having done that? My thought was to either use the turret or the dome version of the 5231 Dahua, and place the camera as far away as i can at maximum zoom in corridor...

I suddenly find myself being pulled in to a side job of helping select security cameras to watch the various entrance doors in an office space. All of the cameras will be looking down hallways at 36" wide doors. At 100ppf a 2MP camera covers 19 ft, so there is no shortage of pixels on...

What is the difference between the E-Z and the R-Z model numbers? like in the HDBW5830E-Z and the HDBW5830R-Z? I couldn't see any difference, except for some reason the E-Z is 1" larger. Is there a Dahua cheat sheet?

It seems like the new Z5 zoom cameras are a good value, at least in the StarLine lineup. I don't think we have any Z12's yet to see if that trend continues. So far it seems that there is only about a $10 difference to the Z. The PTZ seem to be another matter however. Going from the 4x zoom...

Are there any reviews of the newer Stavis 8mp (4K) Dahua cameras? They would likely have less than 1/4 of the low light performance of the starlights and maybe 1/16 of the U starlight, but i think they will be way better than older 3mp and 4mp non- starvis models, and of coarse there is 2x the...
