Good point. DO NOT power your camera both ways at the same time using POE and with a DC power line. One or the other. Lotsa ppl use poe to create a DC power line for the non-poe camera. ie: use POE injector near the start of the cat6 cable run (near the NVR or BI computer. The cat6 cable...

For external mic, @looney2ns provided a great link. It's a long thread, but lotsa info, esp on how to use a poe splitter to provide power for a mic. Regarding the connections, bare wire (without connectors) is actually nice in some installations. If using a mounting box of some kind, where...

Interesting idea. You say you'd The thing is, you don't have much choice in selecting a fixed lens for your camera. eg: 2.8, 3.6, 4.0, 6.0, 8.0, 12.0 If your calculations show you need a 3.25mm, that size lens isn't available in off-the-shelf fixed lens cameras. That granularity in...

And the close visual examination should include looking for burnt components (esp capacitors) or pcb traces. And I'd suggest doing a "sniff test". That can find blow parts also. Good luck! Fastb

That skill will be useful to skip to the front of any line....

A starlight owl! Lookit the size of those image sensors! Many Hobbyists on this forum dream of great nighttime performance. "Who? Who?" "Starvis?"

The NVR manuals are typically not consumer-friendly. English is poor ("Chin-glesh?). One manual covers many, many models. Terms are less than ideal. ("delay" can mean debounce, duration, and yes, delay). When learning this stuff, I sought out better information, so I didn't need to rely...

Sounds like an application for RFID tags. Like Gen2 RFID. The tags are often used at the Pallet Level. As pallets are unloaded from the truck's trailer (with maybe a forklift or pallet jack) and into the warehouse or distribution center, the tags are read at the portal (the big door into the...

As any Doctor will tell you (and Honorary Dr Looney2ns, lol), there is a risk with any surgery. That said, replacement joint surgery is pretty invasive. Infections were a major concern (as well as blood clots). - I missed my brother's funeral because my Dr refused to let me fly for weeks...

We're all getting older. Joints are wearing out, especially if you engaged in activities like running, basketball, soccer, etc. And add to that the sneaker "technology" from back then. Converse sneakers, THE go-to basketball sneaker back then, only had a thin foam inner sole. Thin. Not...

I also hail from Seattle. N Seattle. Like Tony said, Welcome to IPCT !

"NVR in his bedroom " Some customers love the sound of NVR fans, esp on the poe models. (sarcasm... ) Search this site for threads on noise, changing out the fan, sound insulation, etc. The NVR could be anywhere, with a monitor in the bedroom. eg: who really cares where the cable modem is...

Interesting theory! My drive is an conventional HD, specifically, Vivotek WD20PURX 2TB Surveillance SATA Hard Drive - 2TB, 5400RPM, 64MB Cache An SSD, which is faster than a conventional HD, may have less lag. My theory is the lag is due to the NVR closing a file and starting a new post-IVS...

I was involved early in this thread. I still have the problem. I've never heard of a solution or workaround....

I remember the doorbell prank from the old, innocent days.... And I remember making prank phone calls. "You got Phillip Morris in a can? Ya? Well, let him out!!!" Then hang up, and then laugh, laugh, laugh....

Compliments on your English. At least, I haven't been confused. I did try to be very clear in my messages. Reminds me of the old joke: Q: What do you call someone who speaks 3 languages? A: tri-lingual. Q: 2 languages? A: bilingual. Q: 1 language? A: American.

I've used mail settings in the NVR & cameras. For me, both worked. Email from the cam had a benefit, in the the SUBJECT line of the email could be different. From the NVR, all email gets the same SUBJECT. From cams, the SUBJECT could be specific for each cam, so I could tell at a glance of...

Yes, the interface on our two NVRs differ. I bought mine in 2015 or so. My model info is below, in my signature file. So far, we see the underlying required items are in place: email "TEST" is successful. The NVR can send out emails. IVS events are properly scheduled to be recorded...

Hmmm. Here's my settings, for comparison: My 2 cents: I notice you aren't storing regular video (green). But more importantly, your screen doesn't show that you're recording IVS. And your screen only has 3 "types" of recording. Mine shows 4, including IVS. Likely, that's a symptom/clue for...

I can't answer re: ftp. I never used ftp. Re: email: TEST, under the EMAIL tab of NETWORK does work. Good. All settings, the port, email p/w, etc is correct. But emails aren't generated for an IVS Event. Is that accurate? I think that's what you're describing in your brief note... If...

@th182 , I just checked. YouTube shows 33 viewed today. So I think it's okay.... Sorry you're having a problem viewing it... Fastb

A GetVideo link instead of that YouTube playlist link? Why is Get Video better? Did you have a prob playing the video? Maybe instead of the YouTube "playlist", (which simply showed 3 separate YouTube videos of the zombie), Get Video would combine them into a single video, to simply things for...

A Zombie walked up my long driveway. The video shows maybe 1/4 to 1/3 of the length of it. I never saw this guy before. I don't think he's looking to steal stuff. He'd have a hard time carrying anything. And he probably couldn't run away, lol. I sometimes let my dog run loose, since our...

An IVS event can trigger a snapshot or a short video. You can also have the pic or video mailed to you. Those pics and vids are stored in a directory that you can define in the NVR cinfigured under "Storage"

For now it works. It feels like 'borrowed time' though. Until when there's no browser (with or without extensions) that is Dahua compatible.

Year's ago, as a young man, the job required breaking post holes through a thick concrete driveway. The boss rented an electric jackhammer. Shit. The thing was much heavier than a pneumatic (usually the case w/ air vs electric tools). AND it had much less power. My back ached for days....

In a pinch, I've used a pressure washer. Messy, but can cut slices in the glacial scree we have here (dirt/clay that's as hard as concrete). The slices (slots) I cut w/ pressure washer can be used to break away the dirt between the slices. And a bar helps. Like I said, in a pinch. Not for a...

@FlipNJ, Yeah, it sucks. Dahua doesn't treat the homeowner/hobbyist well at all. In fact, our headaches drive people towards Dahua's primary market, ie: resellers and installers. Making it easier for us is counter to their market approach. I just got a new laptop, and am dealing with this...

From my experience, things to consider: Auxillary IR illumination close mounting is best, obviously, but I worry the barely visible (to humans) ir leds in the cam might spook them? Tho 10ft away (my latest captures) didn't seem to bother them. Note: my cam was mounted AFTER the nest was...
