Are you running Blue Iris? I run a Dahua DVR and I’m recording 8 cams at 30 FPS and 6144 bitrate with no problem. Could be not enough computer, you may want to head over to ipcamtalk.com and ask about BI Settings, lots of good BI info over there.

You could try backing off the FPS and bitrate and see if that helps.

In Western NY I never solved the lake effect/blowing snow triggering my cameras issue- (until I moved away from the tundra, which isn't really an answer).

Change your compression and don't over do it on the frame rate.
Also if you are running a VMS (software) set the motion detector to camera side control vs server side (controlled by the VMS).
I know bigredfish uses 30fps but it is not necessary, 10 to 15 is standard unless you need it for a fast action area such as watching a cash drawer in a business.

Heavy rain at night gets me. We haven't had snow since mine have gone up but I am guessing it will get me too.

Thanks for the info will give that a try when I get home today.

I have been thinking about doing this when I get a dedicated machine for the cams. For 8 cams what size drive should one have?
I think a 10 save on the video would be fine. I try to clear it out every couple of days manually.

I currently have the following but outside of Frame Rate and Resolution I really don't know what the rest of the stuff means.

Code-Stream Type - General
Encode Mode H.264H
Smart Codec - OFF
Resolution 1.3M (1280*960)
Frame Rate - 15
Bit Rate Type - CBR
Bitrate 1792
I Frame Interval - 30
Watermark Character - Digital CCTV

Any of these I can adjust some to help bring my CPU usage down as well? The Frame Rate was at 25 so I dropped it to 15.

I also switched the motion detection to the camera from the software.
Hopefully BlueIris will still send me alerts.
I chose the box in the triggers tab for camera's digital input or motion from Motion sensor.

Use VBR (variable bit rate).


•CBR stands for constant bit rate, aims for a constant or unvarying bandwidth level with video quality allowed to vary
•VBR stands for variable bit rate and allows the bit rate to vary but maintains a constant video quality level
•MBR stands for maximum bit rate allowing the bit rate to vary but only up to a maximum value, effectively VBR with a cap.

For you Blue Iris folks, I found this on IPCAMTALK.com:

https://ipcamtalk.com/wiki/opt...ue-iris-s-cpu-usage/

Maybe some of this may help.

Hey Black, on your settings

Why running less than 2mp resolution with 2mp cams?
That bitrate is very low. Double it a couple of times and see video quality difference
Rule of thumb is to match Iframe to FPS

I know a lot of Pro installers say to trim back FPS, bitrate etc, but that is due to bandwidth restrictions over the wire. At home should be a non issue. If I buy a Ferrari I don’t put a 60mph governer on it Wink

As to your question on HD capacity:
I run all 8 cams 24/7, at 1980x1080 (2mp), 6144 bitrate, 30fps, and 7fps at 720x480 on the secondary sub-stream for mobile remote viewing.

I use two 4TB hard drives and get 14-15 days recording using H264H

I think most of the concern is for high cpu utilization with Blue Iris (or maybe in general)?
Not so much on bandwidth or storage.
In many cases in you can push the envelope but if you reach the limit (bandwidth, storage, cpu, etc) you just need to address that individually.
YMMV

That makes sense. One of the reasons I like the newer Dahua DVR/NVR's is that they support the full capabilities of the cameras and just work.

There are a few things the BI can do better, but the list is pretty small..

Hard to beat this one, I've two on order, one for me and one for a buddy.

I like the idea of a DVR/NVR especially considering the cost of about $330 after buying a couple of hard drives.
That price is a bit cheaper than any PC one would buy to run Blue Iris.

Here are the issues I think in my case running a DVR/NVR. If I am wrong and there are work arounds please let me know.

One is limited to Dahua cameras with this DVR (Not a huge deal exactly I just would need to replace one Amcrest).

Not sure Dahua has any wifi cameras or they are compatible with this DVR/NVR. Due to location on 1 camera there is pretty much no way I can run an Ethernet cable to it. Not sure running a Powerline kit to an outside outlet is a good idea. That is about my only option.

Each camera has to be plugged directly into the DVR/NVR. My DVR/NVR would have to be in my utility closet in the basement which is a horrible location for me to view and work.

That NVR like most nowadays will run any ONVIF compliant camera. That said, mixing brands may mean you lose some proprietary features of a given cam, but most will work fine.

On the Wifi connecting to the Dahua NVR, I'm not honestly certain. Doubtful. Dahua does make some Wifi Cameras, but They are fairly new and I cant find much on them. Wifi just drops out too much to be reliable. If you have line of sight, many praise the Ubiquity Nanos as being very reliable. pricey though. Here's good info on them:
https://ipcamtalk.com/threads/...ss-ip-cameras.21907/

If you are running IP cameras no need to home run each cable back to the NVR. You can add POE switches and run many cams to one spot or various spots with only the cable to the switch running back to the NVR. (If you get a POE NVR then yes, but most have the choice of models allowing use of your own external POE switch)

Well we may be on to something here then.

Is it possible to fully control the DVR/NVR from a PC on the network?

If that is the case I could easily Home run the cams to the DVR/NVR in the closet in the basement and run it from my PC in the office.

Yup sure can.

My DVR is 40ft away from my router and my laptop on my desk. Laptop connects to router via Wifi and so does the DVR using a Netgear WNCE 3001 Internet adapter that sits at the DVR providing network access on my LAN.

The Dahua DVR has a web interface so you just log into say 192.168.1.101 via browser on the laptop and walla, you are into the DVR... or cameras for that matter as they will all have their own IP on the LAN as well.

I have a Netgear Nighthawk router that comes with free OpenVPN (I think the Asus routers do also), so I use VPN to connect into my system from outside my network, like with the Dahua iphone app (iDMSS) to view cameras and get alarms etc... I can also VPN in on my laptop and control the full DVR remotely like I can from my desk.

Since clearly I am a novice with this stuff how difficult is the DVR/NVR to get up and running?
In other words how much am I going to be bothering you?
I like Blue Iris and works very well. It has just maxed out my PC pretty much with 2 cameras so I I need a new one. And the OP here has built one heck of a PC and still has a ton of CPU usage and he spent a pretty penny building his PC.
You seem to have zero issues running 8 cameras, I will likely be fine with 6, with the DVR/NVR that costs about the same as the processor alone to build a PC to make Blue Iris shine.

Seems kind of silly to stick with Blue Iris.

Ha! No worries man, that's what they make TeamViewer for Wink I do this stuff as a hobby so no problem dialing in and helping you out.

Seriously if you can figure out BI you'll not have too much trouble learning the NVR. I'm about 1/2 IP networking challenged and old, if I can figure it out you can.

There's a huge thread on that specific machine over at the ipcamtalk forum
Dahua NVR5216-4KS2 / NVR5216-16P-4KS2

It and the 5231 Starlight cam are the most widely used and regarded pieces of Dahua kit over there so lots of info and lots of folks smarter than me to help out if we get stuck. There was a problem with firmware when they first came out, and of course with tens of thousands of video surveillance nerds poking around, inevitably someone will break almost anything if they try hard enough Wink Dont be the first to upgrade firmware on cams or NVR's. Let others be the Beta testers.

I'm on an older Tribrid DVR currently, but I'm ordering one for me and a buddy. Mine wont be installed for a while as its for the HOA and will be after some construction work is done in the neighborhood so we can play with yours till then Wink

Look, plenty of folks are very happy with BI and it does have a few features not found in NVR's if you like tweaking and playing with computer settings. There are also a number of other higher end VMS systems out there to run on a PC. I quickly decided that the important thing is settings and placement of the cameras themselves, lighting, sensors, and focusing on getting that money shot ID for LE. I'm way over the tweaking for the sake of tweaking phase.

I understand your concern.
However, if you have a configuration problem where something is inadvertently out of whack or just misconfigured, would you think a NVR is going to solve the problem?
These NVR's are just cheap ass computers with some other cheap built in components like a poe switch.
They COULD (just be the softaware).
From what I've read Blue Iris is more cpu intensive than other software.
It may be in the VMS software as the DVR's usually have a basic software embedded as well.
Perhaps try another software package.
Normally, if properly configured it does not take a lot of computer power.
