How do you use a wireless security camera and receiver with your computer monitor?

Answer
Hello

you don't want to sue wireless for a number of reason listed bellow.

if you want to view your cameras from any computer just get a DVr with good remote connection then you can connect to it from anywhere that has internet.


I recommend going with a PC based DVR but if you don't want to spend the money I suggest Ascendent's AVP-4120 DVR or Pelco's DX-4000 as they will allow you to view all your cameras instantly from anywhere in the world using either IE. The AVP-8240DVDUSB will also allow MAC platforms as well as PC to remotely view cameras and it uses the new H.264 codec but no standalone will offer the video streaming or performance a good PC based DVR will.

http://ascendentdvr.com/dvr-standalone/standalone-dvr-usb-network-h264.html

Not all CCTV equipment is created equal, in fact there are many options that offer varying performance take cars for example. In the world of CCTV you can find the equivalent of a $2,000 golf cart and a $350,000 Ferrari and everything in between. Both have 4 wheels but that's where the similarities end, itâs under the hood that counts.

95% of all wireless cameras are compete junk and any wireless camera under $400 run on 1.2, 2.4GHZ or 5.8GHZ and wont offer encryption. This is bad for 2 reasons one the signal can easy be jammed, with a laptop you can actually hacked video feeds so a criminal can use it to spy and know a good time to target your business or home.

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. There is a reason these products are 1/10 of the price of good and reliable DVR brand names. The type of seller these products attract are online sellers (ebay) and will make profits margins as low as 3% which means they canât afford to offer good service or allow for RMAs (returns). 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.

Now some products can be made cheaply like ipod cases, screen protectors, and other simple products with no moving parts or electronics. 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.

A true DVR and camera require years of research and development to facilitate the seamless integration of both the hardware and software. DVRs are highly complex systems that must run 24/7, processing millions of images per day and are one of the few products that canât be made both well and cheaply. Cheap and inexpensive products like Q-see, X10, Swan, Lorex, and other low grade DVRâs and cameras sold by Tiger Direct, Newegg, radio shack Sams Club, are not used by any security professional and should only be used by hobbyists.

To be honest the "frys" products are Garbage and are not used by anyone who has worked with CCTV or security products. I They are poor quality especially for IR cameras, due to low quality material, low S/N ratio, and low grade CCD image chips.

Also as far as night vision or IR cameras go most do not give good images in the dark. 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.

Now one option for wireless is using commercial IP radios which are basically wireless routers on steroids and can offer distances up to 40km of wireless with military encryption, this is not a cheap solution but neither is digging a trench. using these radios not only give you a security infrastructure but also communications infrastructures as well for internet and other purposes (LAN network)

Good radio company

now in order to use this wireless network to distribute video you need to buy IP cameras which are similar to IP cameras only they transmit video over networks instead of a cable.

The company I recommend for CCTV products is Ascendent Technology Group they have a large product line and offer better products then Pelco Honeywell and Bosch and are about %20 cheaper and in my opinion have the best IR outdoor camera line up.

In the end you want to buy your DVR from a Brand name DVR manufacture

These brand manufacturers also have a complete line of CCTV cameras and DVR for any application from residential to military and stand behind there warranties.

Compatability of Mac?




LewieG


I have been using a PC for my entire life and I am now considering making the switch to a MacBook Pro.

What is the compatability of files between the 2 systems and can I get the same applications on Mac that I would get on PC.

Really what I should be asking is 'Why should I buy a mac over a PC?'



Answer
There are really no reasons to buy a Mac over a PC, Here are reasons why not. And Mac OS X runs it's own software, not windows compat by default.

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 more 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 either 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 FASTER/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)

**(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: ($700)
CPU: 2.33 GHZ Dell Inspiron QUAD (4 Processor) CORE
SCREEN: 20inch Screen
MEMORY: 4GB Ram
HARD DRIVE: 500 GB hard Drive
OPTICAL DRIVE: 16x DVD/CD Read/Writer
GRAPHICS: ATI Radeon HD 512MB
http://configure.us.dell.com/dellstore/config.aspx?oc=dddwra4&c=us&l=en&s=dhs&cs=19&kc=desktop-inspiron-537s

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 ($1300)
CPU: 2.4 GHZ DUAL (2 Processor) CORE (SLOWER CPU)
SCREEN: 20inch Screen
MEMORY: (upgrade to) 4GB Ram (SAME)
HARD DRIVE: (upgrade to ) 320 GB hard Drive (LESS HARD DRIVE)
OPTICAL DRIVE: 8x DVD Reader/Writer (1/2 speed)
GRAPHICS: Nvidia Geforce 9400M (APPROX SAME BUT LESS MEMORY GAPHICS)
