What is the best home security camera?




Dragonfly


I am looking for a system of 3 cameras, that can record directly onto the internet. I would like to have something that is good in the dark and also has a good resolution.

Does anyone have any suggestions, because I have no idea where to start. Thanks so much!



Answer
Hello

CNB cameras are not high end and are made in china,

Spyville just sell products made in china and are also quite low quality.



Most IR cameras do not give good images in the dark specially cameras under $200. Many companies claim good night vision but there are only a handful of brands who give night vision over 30 feet out doors. normally if a cameras is rated 150 feet of IR it will give you ok images at 30 feet at night and good images at about 20 if rated for 60 feet you might get 15 indoors and will be useless outdoors.

Economical DVR's
Two good economical DVRs I would recommend are Ascendent's AVP-4120 DVR or Pelco's DX-400. The AVP-4120 uses the latest H.264 codec to improve streaming and recording time, and will allow PCs and smart phones to remotely view and control your cameras. These are the DVRs I would recommend that are good quality and affordable from companies who stand behind there products.

Always buy DVR and security equipment from a good brand name manufacturer like Pleco, Bosch, Honeywell and Ascendent: http://www.ascendentgroup.com

Unfortunately many people buy very low end systems which have poor frame rate and bad image quality because they buy from Amazon, "spy stores" Lorex, Q-see, NCIX, new-egg, and other online retailers who sell cheap products for china there were never intended to be anything more then a nany cam and should never be used to provide security.

Not all DVRs are created equal, in fact there are many options that offer varying performance much like the automobile industry. In the world of DVRs you can find the equivalent of a $10,000 Kia and a $350,000 Ferrari and everything in between. Both have 4 wheels and windshield but that where the similarities end, itâs under the hood that counts. Just like any other consumer electronic in the end you get what you pay for.

The smaller the files size the more images are able to be sent, and the faster they can be processed improving both FPS and speed. File size is the heart of any DVR and goes far beyond just its streaming capabilities, as it also determines the recording storage time, how much you can back up at once, how fast it renders and searches video. The file size of a DVR impacts the performance of the DVR in just about every aspect from speed to longevity and is often the most important spec of any DVR.

If you are buying a DVR and streaming is a high priority I suggest you ask for a demo and connect to the DVR to make sure it is able to stream fast enough for your needs. Most DVRs say they have remote viewing but it is often too slow and laggy to be of any use especially if it is a standalone.

Just like any other consumer electronic in the end you get what you pay for. Most retailers and sellers make about a 40-80% profit margin, this is after costs like shipping and overhead. That means when you buy a product that costs $100.00 the manufacturer usually has only spent $30 to build it which simply means itâs not a good product and will probably have a working life of about 2 months. Cheap products are like disposable razors they are NOT designed to last for a long time and you will end up replacing them every 2 months.

DVRs need to be good quality as they run 24/7 (20X more than the average electronic device) and process anywhere from 30-480 frames per second which in a year is over 15 billion images, and a good DVR should last 3-5 years.

Again if you are going to buy no name products save money and get dummy cameras they are just as affective and you will be less disappointed.

Hope this Helps,

Why are CCTV / BNC security cameras such low resolution?




Anomoly


I'm sure that if your going military grade there might be much better but it seems that 'high resolution' security cameras for the most part are '480' which seems quite low compared to 1080 cameras out in the world today. (i.e. the WII vs PS3 resolution).

Am I just way of and ignorant here?



Answer
They are low res because:

-it is cheaper

-that is all that is needed in most cases

-low res can be recorded more time and take up less memory space

You can get a high res camera but it will take up a lot of memory in your hard disk recorder - security cameras record 24/7.

I bought a wireless 4ch DVR Security Camera system?




Kompolaga


I bought a wireless 4ch USB DVR Security Camera system from eBay. But after all I got a camera system I didn't want.

Because it does not record all four cameras at the same time and can't hear the sound from the mic of the cameras.

SO I am wondering If I can use another receiver/dvr software on the wireless cameras to record all four cameras?!

(btw I have Windows 7-64bit)

Please take a look at the cameras from eBay.

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rt=nc&nma=true&item=110592707059&si=qVqvXTpfKQcKFk90%252FtNWkrWSOoM%253D&viewitem=#ht_4236wt_882







HELP! :(



Answer
If you know the manufacture of the camera look for their homepage on the net and then give them a call. They should be able to help you.

Mac or Windows (Snow Leopard or 7)?




R.B.


Ok I know that this question has been asked a Billion times but I need help and this one is a bit different. I have been with windows since Windows 95 and I can personally vouch that it is an innovative contraption. Performance wise my personally favorite would have to be 2000 (no seriously, I had no anti-virus software and I never once got a virus) but XP is good to as it's my second favorite. I have used Vista, its not as bad as everyone says it is but it's not as good as the money that I spent to upgrade from XP to it and then throw it out the window (metaphorically of course)(Glad I bough Home Premium instead of Ultimate). So I recently discovered from my friend that Windows is releasing 7 and that my friend had downloaded the Beta from there website. It was pretty good (fastest startup on a PC I have ever seen in a while, my laptop starts up in 48 seconds), and it loaded up fast. But I also heard Mac is coming out with Snow Leopard which is improving on performance(Me likey). And the regular Leopard is good as well on performance and eye-candy.

So which one do you think will be better for ease of use with similar specs (i.e. faster start-up, least program crashes, performance of regular program, etc).



Answer
I would get a PC and dual boot with Linux, then you get the best of two worlds (Security on Linux and free software and Windows for its support advantages).

PC=Variety of specs, options, quality, prices, vendors, support
Mac=One vendor, limited options, still more expensive. Look below for more information..

Today, Macs use a subset of PC hardware. Why spend extra to get the same CPU chips, graphics cards and OS X isn't as secure as you think..

Don't believe the lies that Macs are better than PCs at graphics/animation.. Dreamworks Animation http://www.dreamworksanimation.com/ under studio click on Technology of Animation, an independent film maker I know uses PCs, a graphic artist I used to know uses PCs also.

A number of PCs can also run OS X (Mac OS) http://www.google.com/search?hl=en&q=os+x+on+pc&btnG=Google+Search&aq=0&oq=os+x+on+ as well just that Apple makes it illegal in order to get Market share.. The reason why Mac can run native Windows is because it is using a subset of PC hardware,

If you decide to buy a Mac for running Windows, you will still have to get the same virus/spyware protection, and run into the same issues as a regular PC.

Now is a Mac worth buying for OS X?

I say: NO... for the following reasons...

ADVANTAGES WINDOWS :
Aprox 90% of the market is Windows and most PCs have windows already pre-installed.
1) Some websites require Internet Explorer, to run IE on Mac you really get ies4osx which is the Windows version of IE running really buggy and illegal if you don't have a legitimate copy of Windows.
2) Supports devices (printers and other things you hook into the computer).
3) More business software/games
4) Want the dock on OS X (Mac)? google/yahoo rocketdock, objectdoc.
5) Used by businesses.

ADVANTAGES LINUX :
1) FREE (most versions are)
2) Install software by eitjher 1) Synaptic Package Manager, 2) Add/Remove 3) Opening a .deb or .rpm file (depending on distribution)
2) Like the Mac OS X effects? go yahoo/google COMPIZ FUSION which can do any cool effect a Mac can do and many ore....

http://www.youtube.com/watch?v=N3gkX9HDfEE (there is no flickering when you use it like on the video, not sure why the person has the flicker)
3) Mac OS X Doc? google/yahoo Avant Window Navigator.Cairo Dock, http://www.dailymotion.com/video/x3rf5q_cairo-dock-mac-os-x-leopard-dock-on_tech
http://www.youtube.com/watch?v=p0hzi22g2DE
4) It is FASTERr/MORE SECURE to surf on the internet
5) Some Windows programs work with Wnehq/Crossover (also avail on Mac, but why pay $$$)

SECURITY
Mac OS X was hacked in 2006 less than 30 minutes, and within 2 minutes in a contest in 2008, and within 10 seconds in 2009. In 2008, Linux and Vista were not hacked until another day when restrictions were lowered. Vista was next, and then Linux. In 2009 Windows 7 fell shortly after the Mac but Linux was unscathed.
Macs are standardized with Cameras, if your Mac gets hacked, the hacker can turn on your camera with more ease.
Please Note: All OS's have vulnerabilities.

VIRUSES
Mac OS X has viruses (and significantly on the rise), a friend of mine has a virused Mac. As more users use Macs, more viruses will come out for it. Especially when users think "they are safe".

QUALITY/PROBLEMS
Contrary to belief, Macs are not better quality. Apple also has been changing suppliers to try to "lower the price" and thus lowering quality. Even with the lower prices, Macs still cost more, they spend a higher percent of budget trying to make it look pretty, and marketing.

Sample of problems: Overheating Macbooks, OS X- not responding to keyboard, some units with 16bit screens, etc. Apple statistics are misleading since Mac users with problem machines are more likely to go out and buy a new computer than PC users. Apple is lowering prices which means you can expect lower quality than in the past. Apple had switched the manufacturers producing parts. OS X also has problems slowing down.

Repairs are more expensive than PCs since the IMac, Mac Mini are compact units, and Apple charges a premium for their services. Some repairs can be done by another repair service but the compact design of the computer causes problems.
With an IMac, if the problem is with the monitor, the whole computer would have to be brought in.
IMac and Mac mini lack expansion.

PRICE
A similar equipped PC is much cheaper to purchase than Mac. Lets use Dell (but you can compare with another PC Brand if you like)

**(LAPTOP)
Dell Inspiron Laptop $849 dropped to $799
15" Screen
CPU: (upgrade to) 2.1GHz Intel Core 2 Duo

**(DESKTOP)

PLEASE NOTE: I compare Apple Mac's vs Dells best deal. If you really want an all-in one the Dell all-in-one has more ram, wireless keyboard and mouse and equivalent to $400 for free making the Imac still more expensive when you matching specs. Personally I don't think the All-in-Ones are a good choice, and consider them overpriced, lack expandability and repairs both more expensive and require the entire computer.

PS: Apple knows that they need to make Macintosh look different than PC so all Macs except the Mac Pro will not have a tower option. Apple's low end lacks expandability but it makes the Mac "look different", if Mac had a tower for low-end, more people would realize the similarities between the two.

Dell: (At The Moment) Specs Below costs $809
CPU: 2.4 GHZ Dell Inspiron QUAD (4 Processor) CORE
SCREEN: 20inch Screen
MEMORY: 3GB Ram
HARD DRIVE: 500 GB hard Drive
OPTICAL DRIVE: 16x DVD/CD Read/Writer
GRAPHICS: (upgrade to ) ATI Radeon HD 2400 PRO 128MB

The Mac Mini since it has no monitor, keyboard, mouse, very skimpy on options and setup and is not the best deal... The IMac is better price than the Mac Mini.

IMac ($1400)
CPU: 2.4 GHZ DUAL (2 Processor) CORE (SLOWER CPU)
SCREEN: 20inch Screen
MEMORY: (upgrade to) 2GB Ram (LESS RAM)
HARD DRIVE: (upgrade to ) 500 GB hard Drive
OPTICAL DRIVE: 8x DVD Reader/Writer (1/2 speed)
