Nice site! But Visio wasn't the recommended one for larger sizes, just "The Best TV Around $500" 43" model: "The 43-inch Vizio uses a VA-type LCD panel while some other displays (including the 49-inch M-series) use an IPS panel. While IPS panels offers wider viewing angles, making them good for a bar or restaurant, their black levels and contrast ratios are much worse. The VA-type LCD panel on our pick offers very good black levels. The local dimming features improve on that. So for most people, the sizes that use VA-type panels will look far better in your home, unless you usually watch from off to the side." Their "Best TV" was the Samsung JU7100 at $1598. They also review receivers and speakers...

There's pretty much no such thing as a "dumb" TV in today's consumer market. If you find one, it'll be an off brand. I bought the Vizio M55 last month and like it. It's GUI is simpler and thus less cumbersome than the Samsung TV we have. It's also 4K if that matters to you.

The site my cohorts keep pointing me at is the wirecutters... who recommend the Visio M##-C1 where ## is 43,49,50,55,60... I've also heard of people who are quite happy with Samsung TV's though honestly I have a Roku so I'd rather spend the money on picture quality then on smartness.

Hey Gang, After 17 years, my venerable 27" Panasonic tube TV finally died. Now... what to replace it with? So far I'm looking at the Visio TVs, but I'd peoples like/hates with their current TV's etc. I like won't be using it as a monitor and will only be watching streaming stuff. I figure this is midly linux related because most modern TV's are running linux! Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

The camera(s) will likely fire a shot once every 20-30 second interval, so its not a continuous stream. Infrared is desirable for when the store is closed and visible light is low. Thanks, - brad A few random thoughts, based on the much larger scale surveillance system we run here: * Cameras are useless without storage. I would strongly recommend against storing the images on the Pi itself, as then someone could very easily walk off with them. Instead, check out a centralized video storage system like Zone Minder. * Think carefully about what kind of images you want - resolution, image quality, and frequency. Set up a test camera, walk around, do stuff in front of it, and see how much really gets captured. 30 seconds is a long time in between frames. With something like Zone Minder, you should also be able to set data retention and long term compression policies, giving you more flexibility. Once you have some settings you can live with, you can then translate those to actual disk sizes. * Assume wireless will stop working, because at some point it will. Wire is pretty cheap (you can get good prices on bulk wire at Monoprice), and it will more than make up for it's cost in reliability, performance, and security. This is doubly true for the 2.4GHz only wifi on the Pi3. * Are those pictures important enough to back up?

At some point you may decide that one shot every 20/30s isn't enough, so having a fast reliable network will become more and more important, as you add cameras and start increasing frame-rates. Depending on the size of picture you want to store (once again think about Frank's other list items -- image resolution & quality) you can saturate a low throughput network. If you're doing multiple cameras, or having multiple pictures coming into the server per second, post-processing of the images on the server end, you will end up with a CPU bottleneck. Look at the low-light performance of your cameras also. You don't want to record a blur ... you want a useful picture of a person that you can show to the authorities. Make sure the target area is well-lit. --MCV. _______________________________________________ Wlug mailing list Wlug(a)mail.wlug.org http://mail.wlug.org/mailman/listinfo/wlug

I'm glad this topic came up because I've also been asked to setup four wireless security cameras. My thought would be to use a raspberry pi 2 (or 3!) and have it connected via USB to a external 250GB SSD then to use zone minder to capture the video. The questions I have are: 1. Knowing the USB's all share a single interrupt... will the pi have enough throughput to capture and storage the video? 2. How many cameras can a pi reasonably support? 3. Does zone minder have retention policies? Thanks, Tim.

Hi, One thing you might think about is how to supply power to all your cameras, computers, etc. If the electricity is turned off in your house, unless you have battery backup, you are out of luck. If you went the route of hardwired ETHERNET you could have a UPS at your main control computer and use Power Over Ethernet (PoE) to deliver up to 90 Watts of power to each node, plenty of power to run cameras, LED infrared lights, computers or other small devices. Most UPS devices can deliver a relatively huge amount of power by today's "Pi" standards, and you can buy switches that can power the leads going off. md On Wed, Mar 2, 2016, 09:27 brad <bkn(a)ithryn.net> wrote: > > > On Mar 1, 2016, at 09:30, Michael Voorhis <mvoorhis(a)cs.wpi.edu> wrote: > > > > On 03/01/2016 09:20, Frank Sweetser wrote: > >> * Assume wireless will stop working, because at some point it will. > Wire is > >> pretty cheap (you can get good prices on bulk wire at Monoprice), and > it will > >> more than make up for it's cost in reliability, performance, and > security. > > > > At some point you may decide that one shot every 20/30s isn't enough, so > > having a fast reliable network will become more and more important, as > > you add cameras and start increasing frame-rates.

It sounds as if the PI is a good platform. The wired/wireless is a tradeoff like any other. I’m not sure i have any network drops in the area the camera would be mounted. If only i had the foresight it would have have network/power drops put on at the top of wall which we just installed this summer. If i can find a way do it nicely w/ wires i will.

At some point you may decide that one shot every 20/30s isn't enough, so having a fast reliable network will become more and more important, as you add cameras and start increasing frame-rates. Depending on the size of picture you want to store (once again think about Frank's other list items -- image resolution & quality) you can saturate a low throughput network. If you're doing multiple cameras, or having multiple pictures coming into the server per second, post-processing of the images on the server end, you will end up with a CPU bottleneck. Look at the low-light performance of your cameras also. You don't want to record a blur ... you want a useful picture of a person that you can show to the authorities. Make sure the target area is well-lit. --MCV.

A few random thoughts, based on the much larger scale surveillance system we run here: * Cameras are useless without storage. I would strongly recommend against storing the images on the Pi itself, as then someone could very easily walk off with them. Instead, check out a centralized video storage system like Zone Minder. * Think carefully about what kind of images you want - resolution, image quality, and frequency. Set up a test camera, walk around, do stuff in front of it, and see how much really gets captured. 30 seconds is a long time in between frames. With something like Zone Minder, you should also be able to set data retention and long term compression policies, giving you more flexibility. Once you have some settings you can live with, you can then translate those to actual disk sizes. * Assume wireless will stop working, because at some point it will. Wire is pretty cheap (you can get good prices on bulk wire at Monoprice), and it will more than make up for it's cost in reliability, performance, and security. This is doubly true for the 2.4GHz only wifi on the Pi3. * Are those pictures important enough to back up?

W - luggers, I plan to rig up a security camera for my wife’s store. Recently a drunk person stumbled in and gave the sales associate a bit of a scare, fortunately nothing happened. A company quoted $4k, which i thought was unnecessary, so linux powered i will go. I recall hearing on the list about a linux security camera potential a year ago with a PI, and a search through old list messages confirms that. The market for these PI-like devices seems to be fast moving. The PI 3 was announced recently, and the wifi option is attractive b/c less wiring is desirable. I know of other similar devices such as, beagle bones, other PIs, and ODROID (mentioned on the list). These devices are out of my domain of expertise and there are many of them. I thought the PI 3 would make for a good choice, but i thought i’d ask the list if there is anything else to consider. Price is not really an option since all these devices are so dang cheap. The camera(s) will likely fire a shot once every 20-30 second interval, so its not a continuous stream. Infrared is desirable for when the store is closed and visible light is low. Thanks, - brad

The existence of Windows malware on a disk doesn't make your linux system infected. Additionally, the "malware" seems to be a malware sample from an anti-virus vendor: http://www.tekdefense.com/downloads/malware-samples/

A few days ago I watched a Matthew Moore You tube "Mythbusting Linux" (Https//www.youtube.com/watch?v=y_lhqg_p21k) and he shows how he got malware and his Arch Linux was hacked. I am using Linux Mint 17.3 and now have an antivirus program. I used Comodo for my XP and have it here. So now I guess we should have to buy an antivirus. I'm also looking for better ways to email and since I now have Yandex and Zoho as well as Gmail perhaps there is one even safer. I would also like to give kudos to Apple for refusing to give up the master key codes to NSA, DHS and the FBI though they have reasonably cooperated with these agencies in the past. All this from a newbie. Thank you.
