Can this be done WITHOUT paying a subscription to a security company? The purpose of the video security system is to keep an eye out on the business after hours. Any info, links or suggestions will be appreciated.Thanks.


Answer
Hello

You do not need to subscribe to any service as long as you have internet and know the user name and password of your DVR you should be able to connect to from anywhere.

I suggest you buy a PC based DVR has they have more processing power and normally have a much smaller file size and offer more features then Standalone DVR's. I know many people buy a cheap standalone DVR, only to upgrade to a PC based in 6 months especially when they are using it to manage a store remotely. Also PC based allows you to record up to 64 cameras where a standalone will have a limit of 16.

File size is crucial to streaming because most DVRâs on the market record at real time performance (30FPS per channel) so on a 4CH is trying to send 120, 8CH 240, and a 16CH 480 images per second which requires way too much bandwidth even for the most extreme internet connections.

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. Some good DVR brands that I recommend are Bosch, Pelco, Honeywell and Ascendent. These brands are what security professionals use, Q-see, Swan and Lorex are only used in residential applications because they are sold by Tiger Direct, Newegg, Sams Club, Costco and other retail outlets but are not used by any security professionals also their tech support rarely speaks English as their first language...

These brand manufacturers also have a complete line of CCTV cameras for any application from residential to military.

I have done projects that required cameras to stream over satellite and cellular networks and the only DVR that could provide the video streaming was Ascendent Technology Groupâs X3 DVR. To give you an example of what a good DVR should stream like, below are instructions on how to connect to Ascendent's X3 DVR using Internet Explorer.

This makes a great demo as it is up 24/7 and camera 1 is a PTZ camera which allows you to Pan Tilt and Zoom in real-time over the internet using the controls located to the right.

Instructions on how to connect to Ascendentâs DVR with Internet Explorer:

1) http://connect.ascendentgroup.com/ (Must be Internet explorer)
2) Install active X control
3) Hit âConnect)
4) DVR type PC
5) DVR code SITE-100
6) User ID Demo (case sensitive capital D)
7) Password demo (all lower case)
8) Hit extend config
9) IP address: 24.66.224.223
10) And hit connect

Again 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-4120 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.


Hope this helps

Is it true that Mac Books do not get infected with viruses?







I have never used Mac but I've heard many times that one big advantage of Macs over Windows PCs is that Macs do not get infected with viruses so I don't have to buy anti-virus software like I do with my PC. Is that true? Why is it that Macs are immune to computer viruses?


Answer
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".

http://www.macsimumnews.com/index.php/archive/poll_have_you_noticed_an_increase_in_malware_viruses_etc_on_your_mac/

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.

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.


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 $$$)
