Is there any known or obvious reason why BI is logging in and out of one of my cameras every 8 seconds? It's a 5231E-Z, if that matters.

My BI crashed this morning. It's version 5.8.5.3 which I assume is a stable version because that's what I got from the download link on the BI site a few weeks ago. Windows says it was a blueiris.exe APPCRASH, faulting module name mfc140u.dll. Now I get into all sorts of information that I...

This helps me understand why I'm not as worried about lightning strikes as some of the rest of you. More info and other maps where this came from New maps reveal unprecedented detail of 36.8 million strikes

This is actually a win 10 problem, but BI is saddled with it. If the wired connection from my BI machine to the switch is physically broken, then reestablished, win 10 does not reconnect. Running the network troubleshooter does not help. The only thing I found to get win 10 back on the...

With Dahua's smartPSS utility there's a really nice feature where you can define a screen window layout (2,2, 3x3, etc.), then drag any camera from a list to any of the windows. Really fast and easy to change the camera view on the fly. Is there something similar in BI and/or UI3? (I...

When using a machine with an SSD and single hard disk, I believe the recommended practice is for both NEW and STORED to be on the hard disk. In this situation, is there any point in having both NEW and STORED? Looks to me like it's useless overhead to copy from one directory to another.

With all the old-timers here, maybe somebody knows this. I've been binge-watching The Silent Service. In almost every episode, the sonar operator in the conning tower is almost constantly pushing a lever back and forth with his right hand. What is this lever and what is he doing? The USS...

I don't know much about these bots we're seeing. They are a step up from spam and trolling, trying to look like serious technical conversation. The only giveaways I see are a low post count and language nuances. The language could improve down the road to not be a giveaway. I have a lot of...

Is there a way to listen to camera audio in smartPSS live view? There's an icon to turn on the speaker, but I hear nothing and can't find a volume control anywhere. Works fine on playback. I've doing the live view through the NVR, not with the camera device configured in smartPSS.

I ran into another new big brother thing today for the first time. One of my financial accounts is going to require creating an id.me account to continue accessing it. I don't want my info in yet another database that can will get misused. On one hand I'm thinking of closing the account, on...

Are others of you seeing the same increase that I am? 2023 rate increase 42%, after 16% last year and 9% the year before. This is in Oregon, not in a flood zone, not near the ocean, and not close to the Portland utopia.

Can someone help with a network problem that has me stumped? It's isolated to a single windows computer. It reared its head when I replaced a Dahua 2231 camera with a Dahua 5442 camera. The 2231 was on ip address nnn.nnn.nnn.228 in my network. I changed the 2231's IP away from .228 and...

I'm starting this thread to be a resource for people wanting to use Dahua IP cameras to monitor and view wildlife. If you're among the majority of users who want your cameras to ignore detection of cats, dogs, and other animals, you are fortunate that the newer cameras do this quite...

I echo all the praises of the color-4k-x camera with one exception: Line crossing and intrusion are not working as I'd like them to. People and cars are detected with impressive reliability. Even tiny images in the distance trigger the IVS. On the other hand, it doesn't pick up animals. I...

This is mainly an FYI for anybody using smartPss to remotely connect to a Dahua NVR. I've been doing this using Dahua's P2P function, and was inspired by another post to try remote desktop instead. My main motivation was to be able to access a couple of other monitoring apps while on the road...

I run a Dahua NVR with no POE ports, so don't have any experience how they work, and would like to learn. I think I understand how it works when all of the NVR channels have built-in POE ports, as with a 5216-16P-4ks2: Plug each camera into a POE port one at a time. NVR adds it in...

I found a few related threads, they're pretty old and don't address my primary concern. Context is a small church, wants camera coverage for 3 buildings separated by 80 feet or so, knows I have a camera system, therefore I volunteered to get it done. From my experience with my own system I'd...

Is there any hardware documentation for the alarm wires coming out of the cameras? For the NVR it's in the NVR manual, but I'll be darned if I can find it anywhere in the camera manual. For the alarm out the wires are labeled 'alarm out' and 'alarm out gnd'. For the alarm input it's 'alarm...

The facial recognition company Clearview AI is telling investors it is on track to have 100 billion facial photos in its database within a year, enough to ensure “almost everyone in the world will be identifiable,” Would even George Orwell have foretold this? I find it scary. Some have been...

I assume a lot of you will be getting this notice. I wonder how many people will want to rip out what took so much work to install? Monoprice Voluntary Product Recall

Anybody know offhand what this green dot and number mean? It doesn't show up on the camera or NVR GUI, only on smartPss. Don't bother looking in the manual, already tried that.

I want to make sure I'm not making a bad assumption (never happened before but there's always a first time)! I am assuming that with a Dahua PTZ camera, all of the PTZ control is done over the network interface and no other wiring is needed. Specifically, when the network connection is over a...

In comparing specs of cameras with different sensor sizes it felt to me like the specs were inconsistent. After a lot of number crunching I'm convinced they are. General conclusions listed first. They're based on only 2 specific camera models so it's premature to apply them widely. Corrections...

For all of the various bugs in smartPss, the biggest gripe I have is that it keeps setting itself to high priority, which really gums up the response of other apps on my i7 system. Anybody know a way to block it from doing this? I don't mind changing its priority one time after launching...

The cameras have a long list of features that would seem to be of no use and/or a security risk for a small camera system. I realized that I don't know what a lot of them are, even though they are enabled by default. For example, on this settings page: Do we need to have any of these enabled...

1. I see the trigger highlights in the live view. Is there a way to have them show during playback? 2. On the timeline, is there a way to tell which camera caused a trigger, or a way to display triggers only from a single selected camera?

I wanted to access a camera at its default address of 192.168.1.108. It's for sure online as the Dahua config tool finds it at that address. I typed the following route command: route add 192.168.1.0 mask 255.255.255.0 0.0.0.0 The routing table looks right to me: No response from the...

I have a friend seeking info for something I know little about. He want to set up a single outdoor PTZ camera with remote access, and recording not required. I'm willing to help him set it up but I don't want to have it turn into a huge project or need ongoing support. I could just steer him...

I have a new-to-me Elite Desk 800 G1. I notice that when it's supposedly powered off, the network jack is still active. Is there a BIOS setting to get everything turned off?

(Edited to add findings after 7 weeks of testing and experimenting. Initial post is immediately below) The IVS on my T5442TM-AS won't pick up anything but large objects. It picks up people and deer, while dogs and cats walk right through the tripwires and intrusion boxes without detection. By...
