Q. Just trying to get input from someone that has an antique mall of similar business. I want to purchase a camera system that I can set up in "EACH" booth or atleast every other booth. Some can be dummies but I would like for atleast half of them to be the real deal. I ahve heard of dealers using globes and dummy cameras to deter thieves; does this work?
What system would you recommend and please don't say a 10,000 one, I cant afford that at the moment.

A. Hello
Dummy cameras are the worst possible they don't provide security and if someone is injured or claims to be injured in your store they can sue for providing a false sense of security. No professional security installer uses dummy cameras.
Here is a DVR that will work perfectly for you.
http://www.ascendentgroup.com/x4s.htm
I would recommend a Standalone DVR as they are more reliable and since they are linux based they are virus ans spy ware free.
The X4S Series DVR is an intelligent and professional CCTV management solution, integrating the latest technology and the most advanced features while maintaining a simple, intuitive, and graphical interface. The X4S Series DVR is a 24/7 turn key solution that meets demanding security needs to suit industrial and commercial applications. The X4S DVR is compatible with the X4 platform, allowing it to act as an IP server, while still remaining a standalone solution and allows you to view your cameras instantly over the internet with a PC or cell phone like the I-phone.
also here is some information on DVR and cameras you may want to read before buying a CCTV system.
Not all DVRs and security equipment 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.
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.
Many people have the misconception that a PC-Based DVR is simply an off-the-shelf PC with video capture (encoder) cards, display (decoder) cards and some generic OEM software. A true DVR requires 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. This makes consumer-level hardware inadequate for DVRs which is why Ascendent uses custom-built PCs with performance-level hardware.
My personal favorite DVR is Ascendent X4 series: Ascendentâs Tri-Fusion Hybrid Platform allows for the creation of a true hybrid surveillance system by utilizing the advantages of Analog, Megapixel, and IP technologies for unparalleled customization and expandability.
The X4 also uses the latest H.264/SVC codec offer video substantially better quality,. While its file size sizes is 30% smaller than MPEG-4, 60% smaller than MPEG-2, and exponentially smaller than MJPEG.
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.
I recommend Ascendent as they are less expensive because they cameras for companies like Bosch and Pelco and offer better performance but any of these 3 brands will work well.
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. You want to get a good bran name otherwise you will likely buy a product that work and cant be returned.

Where can I learn more about Linux?
Q. I'm only in high school, but I'd really like to learn more about Linux, specifically securing servers, networking, and command line stuff. It's hard for me to learn on my own. Books are helpful but I'm looking for more of a classroom environment with other people I can work with.
My school does not offer any classes in Linux.

It doesn't get any simpler. And, of course, there's Linux for Dummies at your local bookstore, the For Dummies series of books runs around $20 each and is usually the best bet when starting to learn from scratch.
And there's probably a Linux user group in your town -- Google it.

Best programming language and software to learn first?
Q. Hey all.
I have no experience with programming, but I'd say I know a decent amount about computers and how they work, and I on them quite a bit. I really want to learn how to program and write code.
What's the best language and software to start from? Any good tutorial books to go along with this? Like a Dummies guide to C++ or something?
Thanks.

A. Well there is a "C++ for Dummies" book out there (as well as an "More C++ for Dummies")...
Your question is a difficult one, as it very much depends on what you intend to program... and if you're willing to learn some extra languages just to learn good practice or a concept.
For general-purpose programming I would recommend C++, but be sure to also learn some of the "pure C" (structured) part of the language before you start in on object-oriented (or you could learn C first). There is a short way from C to C++... and a short way from C++ to Java or C# ; so it's an excellent start.
That said, if you have the time, starting with Pascal (which admittedly is on the endangered-list as far as programming-languages goes) will force you to learn good programming practices -- like that all parts of a program (constants, declarations, functions) have their place, and always declaring before using -- which you can take with you to other languages (or not). Naturally it also introduces branches, loops, functions/procedures, types, pointers and object-orienting. The Pascal language is also used in Borland Delphi, which let you make Windows-program (it's similar to VisualBasic, but uses Pascal instead of BASIC).
If you really want to sink your teeth into the beauty of Object-Orienting, I would suggest trying SmallTalk to really understand the concept of OO -- before you dirty yourself with one of the "lesser" OO-langauges; like C++, C# or Java (C++ is basically C with some OO glued on top of it. C# and Java are both heavely influenced by C++, and carries some "bad things" because of this. SmallTalk on the other hand, is all OO... even the language itself consist of objects in a well-defined hierachy).
+++
If you intend to make programs for MS Windows only, C# is excellent.
If you want a RAD (Rapid Application Development, where you first create the window with it's widgets, and then assign small programs for what will happen when the widgets are manipulated), then Delphi and the simpler (and more primitive) VisualBasic are good for making Windows-programs.
If you intend to program GUI-programs for different platforms or for Linux/Unix, then the Qt-library and it's RAD -- Qt-Designer -- may be worth a try. This is a C++ library (ie. extension), so you program in C++.
Java also let you make GUI (Windows-like) applications that can run on different platforms, but they tend to be a bit "sluggish".
+++
If you're thinking more of making small usefull scripts to help system administration; Perl and Python -- and perhaps Tcl/Tk and Ruby -- are better suited.
If you're thinking about application for web; Java and JavaScript are good for the client side... while Perl, PHP or ASP -- together with SQL -- is good for making programs to run on the server-side.
If you're thinking about Artificial Intelligence and making programs that makes conjunctions based on a list of facts and a set of rules; then LISP or Prolog may be languages you shold look at.
+++
As I said it depends on what you want to program. But the best for all-purpose programming is probably C++... maybe together with Qt to make better Windows/GUI programs.
