IR Light Strip for IP Nightvision?
MR2 replied to jdoggg1's topic in IP/Megapixel Cameras and Software Solutions
just a FYI, those LED strips I was testing running 24/7 lasted around 6 months before catching fire -
Picture quality of a 12MP camera - can't even read plate num
MR2 replied to fa355115's topic in IP/Megapixel Cameras and Software Solutions
not many, so much of the sensor is wasted -
Picture quality of a 12MP camera - can't even read plate num
MR2 replied to fa355115's topic in IP/Megapixel Cameras and Software Solutions
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? -

MR2 replied to fa355115's topic in IP/Megapixel Cameras and Software Solutions
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 -
IP Camera System while using Powerline Adapaters
MR2 replied to tcmw's topic in IP/Megapixel Cameras and Software Solutions
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 -
Gigabit Switches or Fast Ethernet Switches?
MR2 replied to tdk1988's topic in IP/Megapixel Cameras and Software Solutions
PoE Gigabit is what I'd do, no-one should be buying 100mbit stuff anymore. -

New Dahua 4K - 12MP camera - IPC-HF81200E
MR2 replied to LittleScoobyMaster's topic in IP/Megapixel Cameras and Software Solutions
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 -
New Dahua 4K - 12MP camera - IPC-HF81200E
MR2 replied to LittleScoobyMaster's topic in IP/Megapixel Cameras and Software Solutions
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. 3mp http://i1056.photobucket.com/albums/t370/mgoodwinmr2/3mp_zpsc5a1t6ug.png 12mp http://i1056.photobucket.com/albums/t370/mgoodwinmr2/12mp_zps8oaksylr.png 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. -

MR2 replied to LittleScoobyMaster's topic in IP/Megapixel Cameras and Software Solutions
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 -

MR2 replied to LittleScoobyMaster's topic in IP/Megapixel Cameras and Software Solutions
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 -
New Dahua 4K - 12MP camera - IPC-HF81200E
MR2 replied to LittleScoobyMaster's topic in IP/Megapixel Cameras and Software Solutions
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. -
New Dahua 4K - 12MP camera - IPC-HF81200E
MR2 replied to LittleScoobyMaster's topic in IP/Megapixel Cameras and Software Solutions
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 -
NVR Server transferred to new Server room 1400ft away
MR2 replied to Alponching69's topic in IP/Megapixel Cameras and Software Solutions
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 -

it was the first post... the OP swiftly ignored it lol -
NVR Server transferred to new Server room 1400ft away
MR2 replied to Alponching69's topic in IP/Megapixel Cameras and Software Solutions
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) -
NVR Server transferred to new Server room 1400ft away
MR2 replied to Alponching69's topic in IP/Megapixel Cameras and Software Solutions
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? -

Can we use the existing company network/bandwidth?
MR2 replied to max_preuss's topic in IP/Megapixel Cameras and Software Solutions
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 -

MR2 replied to max_preuss's topic in IP/Megapixel Cameras and Software Solutions
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 -
