********** - Věda a technologie
you have just explained in 4:24 seconds what it has taken my lecturers 7 weeks to explain. Thanks Eli.
It is great to see that you worked out the sponsor spots in your videos, Eli. Two of those really caught my interest.
Great video! With regards to potential hacking vectors, would it be ideal to keep your devices on a LAN or would that not be possible with the tech?
One thing that is a royal pain in the ass, at least with low end cameras, is changing motion detection sensitivity settings. You can have one menu on the NVR and slide a bunch of bars, or 30 separate cameras with 30 separate IPs and 30 separate logins and ahhhhhhhhhh... scalability on that. What a nightmare when you realize you need more sensitivity. What you said at 16:46 about bad configurations couldn't be truer.
It is worth configuring to some extent. A lot of NVRs that are priced where most will actually pay for them have shit incoming bandwidth. I mean your regular small office or deli. A bank or 100 user organization will pay for good stuff, fuck if a deli is paying for AXIS cameras most of the time. :(
I saw a Hikvision NVR, 16 channel, max incoming bandwidth 100 mbps. That's 6.25 mbps per stream. After overhead, closer to 4-5 mbps, because when you use 6.25 mbps for 16 cameras it claims you run out far sooner.
It advertises 5 megapixel compatibility. You know what 5 megapixel images at 4 mbps look like, with embedded-ip-camera-level encoding... shit :(
Eli, this is a great video. I've been doing Big Data in the modern format since Feb 2014 and lately have been contemplating making a Hadoop cluster of 4-8 Odroid XU4's and a new D-1541 low-powered Xeon server running Hypervisor level1 virtual masternodes on fx. ESXi. Should be awesome in a tight closed network.
I know this video is basically about that "local big data" (or local initial machine learning) and then solving an initial subproblem (or even just zipping the data before sending it) but this exactly what I will be doing down the line. Already doing some Rpi2 motion sensors that does some initial intelligent processing on data picked up and then streams important outliers to Kafka and then on through Spark and into a website that runs an auto-updating JS control to show "live delayed" data from all the Rpi's. Its really neat that a major YT'er (>500k subs) cover this stuff, thanks again!

So helpful.... thanks Eli.
i woud like to hear your opinion, how to get protected from rensomware, dince i know a few hi skilled people just got screwed with this, and i keep thinking i might be next
Thanks for vid man, you helped me get my IT degree
Meaning all videos
Very much informative... Thanks dud...
First!
And these kind of videos really make me stick through the stuff that isn't applicable to me.
Thanks for this video/ I understood better her.
Very COOL! But, I was sitting with an old guard a few years ago, and he was having a hard time getting six cameras to show up on his screen. He asked me if I knew anything about it!
Audio books? LTT reference?
+Mark Murarescu How do you mean?
Pushing computing/intelligence to edge of the network instead of in servers. For IoT so less bandwidth is needed. Example, instead of sending surveillance data to server to compute, we could compute in surveillance camera itself most of time and send the most relevant data to server. Devices can decide when to send data and when not to. Price of technology becoming cheaper which enables edge computing. For example, raspberry Pi just 5 euros. Also, number of devices becoming too much for single server to handle, so we need to distribute computing to devices. Reducing load of network --> reduce load of server. Offers new functionalities that never thought about yet. Problems of edge computing: bad configurations more common. Hacking concerns. License costs because adding functionalities is separate thing.
what is "we are going engine"?
Clicked and looked at all sponser links welcome bro
Sir.....This technology you're talkin about is it implemented? is it working? or it was just an idea??
I like the video camera example
ELI DO A VIDEO ON ACTUAL EDGING
Very good explanation, subscribed . I am computer science student now. What requirement one should have to make a career in edge computing ?
Thanks for your videos, they are very helpful. I have a question for you and hopefully you can answer it because I'm very confused now. I currently work in IT industry(at the bottom), and for the last year I've been studying servers, networking, and all of the Microsoft stuff to prepare myself for a jump into system administration. However, recently I've heard a lot(A LOT!) of talks about the Cloud and how it's going to kill jobs like sysadmin and so on. We just rolled our on-premise exchange server into the cloud(365 platform) and management is now talking about virtualizing all of out desktop boxes. All I hear now is optimization, downsizing the workforce, and new job postings for sysadmin now require a mix a different disciplines(unix, windows, networking, and some coding). So I looks like you will need to be a
master of many trades in order to compete and survive in the IT field. I feel like I just waisted a year for studying obsolete technology. Can you share your 2c about this?
Am I the only one who likes Eli's roomdesk? I wanna have working room like that.
@Eli the Computer Guy, why don't you show your sponsors logo on your computer screen, when thanking them? Or is it something that CZcams won't allow? Thanks.
+TheGray Aviator ... it violates YT's rules...
+Eli the Computer Guy More of a reason to ditch youtube and run your educational videos along side your main website and advertise your sponsors as much as you like.
Even if it were NOT to violate their TOS, they have been changing these things a LOT. Right now, that is on the edge of being against their rules, tomorrow it may be fine, but next month it may violate their terms.
whoa, the 1440p looking nice.
I need to show my friend this he's been looking for something like this forever thank you
Ps:you and grade are so right about CZcams
"We're going edging!"
Hey, Eli!
Did your opinion change on Linux as a desktop OS?
I changed to Linux Mint a week ago and watched your "introduction to linux" video.I dont have any problems hobby progging and gaming, enjoying media of any kind, heck, everything I insert into my laptop works off the bat!
+Michael Govard Yeah, it works off the bat with the three programs that support Linux.
John Doe What programs am I supposed to miss?
Michael Govard The thousands that Linux doesn't support?
John Doe You still havent named one.I surely am more demanding than the average internet-browsing and media streaming type and havent missed anything yet.
Michael Govard Good for you, but I wasn't so lucky. Not even half of the games in my Steam library were supported on Linux.
What do you mean by telephone system :D
What is this please? I am not understanding.
Is the bugcrowd.com a real company? None of the links work!
lolx u had to type bugcrap.com
walk really slow if I ever visit the Harvard campus. Pink Panther cant be stopped!
my wife get addicted and we just finished season 1 ))
Please do a video on Zigbee and Daintree Networks I will marry you.
lolx
Hey Eli, I was wondering, could you make a video giving a bit more information what is the basic job of a DevOps, how to get into that kinda of a job and does it have a future.
Under 301 club
Bugcrap ? ops :p
Huh...don't know what to say
Lmao

they have the same price
thanks
+OUALID OUALIDOS You should these questions ask at the Toms Hardware forums instead. But if you only consider these options, then the 3543, as it has the best CPU and an Nvidia gfx card. The Nvidia cards are great but may burn out in 2-3 yrs time. That said, with patience, screwdriver and care, you can replace it yourself, or just get the insurence.
No matter which laptop you choose ALWAYS get an SSD hard drive, not an iron one, even if there isn't much space on it.
Personally though, I would rather get a laptop from Eurocom dot com (M5 Pro) even if they are in Canada and just keep it on power all the time. Battery and gaming are not good friends.
Thank you sir
Honestly, probably thé worst example thé CCTV caméra sending only when theres motion.... Perhaps its better to wait 6 years before trying to explain what s just out in the hood
will be fun when edge computing will morph into crypto Blockchain computing, and then you will hate us who dont worship money and make technology for the greater good rather than filling our own pockets only.
