    How much bandwidth does a particular camera use - How do I calculate it?

    scrounge most any old Windows PC with at least a core i5-3xxx just for playing around, get 1 or two cameras to evaluate, I recommend the EmpireTech IPC-T5442T-ZE, and a cheap 4 port PoE switch, hook all this up and install the Blue Iris evaluation copy to play with it and see how it all works...

    How much bandwidth does a particular camera use - How do I calculate it?

    note that the majority 4K (8Mpix) cameras tend to have smaller pixels, so have poorer low light capability at the sorts of shutter speeds needed to prevent motion ghosting. Right now, a 1/1.8" camera chip with 4Mpix, such as the Dahua/Loyota IPC-T5442T-xx series have the best IR night vision...

    How much bandwidth does a particular camera use - How do I calculate it?

    my better cameras are 5 MPixel at 15 fps, and are running around 8000 kbit/sec, which is 1 MByte/sec. I tried lower data rates, but the video looked messy, with pixelation. 10 of these would come close to saturating a 100baseT link.

    Is there a Blue Iris equivalent for Linux?

    I wonder what the NVR vendors use as their basis, surely they don't all write their own from scratch. I am assuming that the majority of the NVRs are linux based

    Is there a Blue Iris equivalent for Linux?

    I just did some googling and stumbled on Shinobi, which runs on Linux (or Mac or Windows). there is a free community edition, and a more frequently updated licensed version. has anyone tried this?

    Swann security systems ?

    Ok, its a 16 channel coax system, the DVR is a Swann DVR-4575, using 16 1080p coax cameras with PIR motion detect, probably PRO-1080MSB. Only 4 cameras are dead, so my first guess is, its just a power supply issue, those 4 cams are likely on their own wall wart with a splitter, so I just...

    Catalytic Converter Theft on Nextdoor

    I've got a couple Ryobi lithium 18V tools, and for my uses they are fine (a drill-driver, a small rotary handheld saw, and a angle grinder). I had an older Dewalt drill (nicad powered) that was a workhorse, but the batteries were dying, and I won the Ryobi drill + saw in a raffle, so I...

    Passive PoE options for SD49225T-HNI and other similar OEM models

    the 100m length for ethernet has nothing to do with PoE, it was baked into the frame timings back when things were 10Mbit on coax and twisted pair, and related to the round trip CSMA/CD (carrier sense multiple avoidance/collision detect) timing window and gap between ethernet packets. signals...

    Swann security systems ?

    ok, turns out, the access my wife has is just an image uploaded to the lodge's website, and not the actual NVR.

    Swann security systems ?

    my wife volunteered me to help the local Elk's Lodge debug their security camera system that died last month. I know nothing about it yet other than that its from Swann, and has at least 4 cameras. I don't know how old, I don't know if the cameras are PoE or analog. I'm going to try and at...

    Losing signal on all cameras randomly after BI 4 to 5 upgrade....

    Is ColorVu any decent or more of a gimmick?

    I've avoided any dome cameras, and so far just have some bullets and mostly turret/eyeball cams. I like the turret form factor but I guess I can't get really long FL in that, because I want a 20mm or longer lens for my driveway entrance camera.

    You guys agree with this guy?

    yeah. I have a couple UB mFi Power plugs. they discontiuneed the whole mFI product line, but it was power management. I have, I think, 3 of the single plugs. one runs the hot water recirculator pump in the garage, and a macro in their mFI controller program shuts it off if its been on for...

    You guys agree with this guy?

    to my naked eye, the LEDs on the Reolinks are visibly much brighter than those on either the Dahua or Hikvision turrets I have. I chase far more spiderwebs off the Reolinks than the others. I guess i didn't word it strongly enough, I was trying to say, the Reolinks pretty much suck at night...

    well, i have bi 5.5.x and a mix of currently 7 reolink, dahua(empire, amcrest), hikvision, and haven't had any issues. i'm using cheap generic 'stupid' POE switches

    You guys agree with this guy?

    A few random comments ... I have a couple cheap ($49) Reolinks, I thnk they are the RLC-410? they work fine with BI, but their IR illuminator is just way too bright and is a total spider magnet, and yeah, the night vision is not very good for motion, and if I turn down the illuminator the...

    if they were using simlpe html forms, paste would work automatically. they have to be doing some weird JScript stuff to break copy/paste.

    Is ColorVu any decent or more of a gimmick?

    its people you want to see, not cars driving by. ok, I like seeing animals, too. to reduce noise, I mostly use 1/60th as my night shutter speed, and tune the 2D and 3D noise reduction til it looks good

    Impressed with HFW5442E-ZE

    I would do night color if I had soft indirect lighting evenly distributed around my drive and walk ways. but as an amateur astronomer, I like the dark, and i'm hesitant to add lights to ruin that.

    oh, let me add this to that. the MicroLight IR illuminators are awesome. even light for exactly the specified cone, with a clean cutoff.

    Impressed with HFW5442E-ZE

    I dunno, IR has always looked plastic to me, but that doesn't bother me, I've seen enough of it to know what is what.. I want to run an IR light tape around my eaves and shut off all the camera illuminators. heh. suppose it would be smart to turn them all on again if there was any alarm

    Why can't drivers with good driving etiquette report drivers with bad driving etiquette to the appropriate authorities?

    speaking of Excursions. last night, an Excursion t-boned a Prius at a rural T intersection not far from here, killed the driver of the Prius instantly. nothing like 9000 lbs smacking into the side of 3500 lbs to ruin someone's day. it was at about 6pm, so hours before sunset, who...

    Dahua cameras and integration with home automation setup

    yes, it has a lot of options, but concentrate on the IP camera profile, which I think is "T", and its not that bad. it does include both video streaming AND event/alarm alerting. as a client user, rather tahn as a device, you only need to invoke the specific functions you are interested...
