MR2

just a FYI, those LED strips I was testing running 24/7 lasted around 6 months before catching fire

right application

not many, so much of the sensor is wasted

a very long time ago I asked some industry professionals about their thought's on the Fisheye's, generally they came back and said they were crap

The night's pretty good, a lot better than I've seen some cam's

yeah that looks about right, how does it go at night?

it's a Fisheye (so think pixel density) and the 12mp you got is one with a 1/2.3 sensor...

I find the Dahua 1/1.7" sensor is way better than the Hik one, there are quite a few 4k cam's running around with 1/3 or near enough sensors which are absolute junk

the powerline adapters are in pairs, so one would be installed near your NVR the other near the camera, I'm using it for a few and it works just fine

PoE Gigabit is what I'd do, no-one should be buying 100mbit stuff anymore.

What VMS are you using with the 12MP Dahua?

Milestone

 

Curious what lens you went with for this camera.

it comes with a good Varifocal, the FOV and focus can be adjusted in the camera's web interface, so no need to spend time getting everything right while your up a ladder etc

ok these things are crazy... there is a HUGE improvement, you want to download the two BMP's I've uploaded, then zoom in on an area to get an idea.

going to see what the Night vision is, and then I'll see what I can do about a youtube demo...

going to be moving this thing around between a few sites demoing, so I'll get some views.

when I get some time I'll post up some thoughts too.

FYI the unit arrived at my normal site yesterday (it got here in 3 days... nice!) I'm overnighting it to the site I'm presently on to play with should have some sort of demo's or screen dumps tomorrow arvo

Damn, I hate it when I try to make honest comparison test, standing on -10oC freezing my ass off and everyone is suspecting some kind of manipulation or marketing action

well, I appreciate the effort, both to deal with the people who make "no good deed goes unpunished" happen, and to reply to this thread I'm actually a bit surprised there is so few enthusiasts playing around with this 8+mp stuff so (almost) anything from anyone is most welcome

we have some 2CD-3332/2332's around so I'll see if I can throw up a direct comparo when mine turns up

Maybe Dahua will use same sensors?

I really hope so... I'm really hoping that one of the big two get it right eventually...

the Dahua gets the ability to use the full sensor right (IE a 4:3 12mp setting), but then it has the IR sensors under the dome which will have that reflection issue

Dahua also told me that to get H265 encoding will require new hardware, so that's a bummer too.

if I have the choice between 8mp + H265 and 12mp + H264 it'll be a close call, probably come down to Lens if they are a similar Sensor.

I'm honestly a little surprised we don't have more people testing this stuff.

should ship today, it seems they are not sending many out, so we might be one of the first, if it arrives end of next week I'll pop into work and pick it up to play with

run at least 12 strand fiber you then have spares plus you could expand you other network. Cost it out we have installed a lot of armored fiber that was very inexpensive compared to intermediate switches.

 

 

minimum quantity of fiber from sellers over here is 500m, price per meter is $4... he won't have his own terminating gear so there's another $1k if it's got lots of cores, the media converters will be around $250 each if he does not have switch's with transceivers in them...

 

not disagreeing that fiber is the way to go in most situations, but if he's being cheap and nasty (you getting that Vibe? I'm getting that Vibe)

 

as opposed to a few boxes of cat 5 at $100 a box (for 300m per box) and a few cheap $70 switch's.......

 

Don't get me wrong, I think the whole approach is wrong, but what he's got is what he's got!

 

$4 a foot? You can get 50/125 fiber for .50 a foot and you can order it pre terminated for an additional cost.

that's there price here in AU you lucky buggers get everything cheap

Hi. I would also say go fibre ....

it was the first post... the OP swiftly ignored it lol

if we put a switch every 90 meters.. will it work??

It'll work...

if you use high grade cable you can probably get 150m between switch's (we've done a few very long ones and have not had any issues with years of heavy use)

I assume that at 1400ft away they will already have a network connection through to their origional network? or are you doing that thing where the NVR is on it's own network?

we just bought one to play with ipc-hdbw81200e-z

you'll be fine if it's just the internal network as long as it's all gigabit, when you get several hundred devices you'd maybe need a 10gig backbone, but then when you have that large a network you will likely have IT intergrators who will be actively monitoring your IP Cam systems impact on the network.

maybe if all the cam's were in Casino mode you'd see some decent traffic, with normal H264 you'll find even 20x 3mp cam's are using maybe 10% of a gigabit connection combined (we register under 100Mbps for each 20 pack of cam's on constant record)

if you find any 100mbit switch's they should be replaced anyway

You will have no problem.

 

I would suggest you do a Step by Step approach, rather than saying it'll be fine, how about saying "lets try this, but keep an eye on if things slow down and if you have a quota limit"

 

then if they notice anything just look at increasing the speed of their connection slightly or increasing quota if they are on that sort of link

Because "you will be fine" is the correct answer based on the information provided. What you are stating is "i have no clue so why dont you test it and see. If it doesn't work get faster internet." That doesnt help the OP.

There are substream settings on the NVR to address this issue.

Sure, use a blanket statement then

You will have no problem.

So what your saying is you have nothing useful to add to this thread?
