security systems

The level of violence and criminal activities we read about in newspapers and internet web sites make us concerned for our security. To be able to lead more secure lives, the more affluent among us choose to live in gated communities. Those of us who are not so prosperous turn to security systems. But even then, there are so many different types of equipment to choose from that it is easy for the cost of security systems to shoot up to prohibitive levels. The good news is that, with a little forethought, most homeowners can afford the type of security system that they need.

Practical Considerations To Keep Security System Installations Affordable

If you automatically opt for security systems with all the bells and whistles, you are almost surely going to spend too much. But if you take the time to assess your concerns and the security equipment required to address them, you are likely to find a security system is within your means.

There is nothing to say that you cannot do the initial assessment on your own. During this assessment you need to list down all types of perceived threats. You also need to make a list of the areas you need to monitor, including areas where vulnerable residents in your home (such as teens requiring a certain level of supervision, the elderly and the infirm) may be. This article provides tips on improving home security.

When you plan your video surveillance equipment, make sure you cover all vulnerable areas without overdoing it. Using a camera which has pan, tilt, and zoom (PTZ) capability is a good way of reducing the number of cameras needed, whether for indoor or outdoor use. Indoor cameras don’t need to be weather proof, but make sure the ones to be installed outdoors are. Make sure to ask only for the features you really need, such as low light video capture capability when the camera will be deployed in a dark area. If you want to increase the deterrent effect, for a few bucks more you can get some dummy cameras installed.

When choosing recording equipment, it may be wise to use digital video recorders. DVR’s use hard drives (the same type installed in your computer) to store video footages. Many DVR equipments can now store in excess of 500GB of video; old recording equipment will require the use of many tapes which have to be replaced frequently.

Remote access capability is a feature that increases the usefulness of security systems many times. It enables you to look into your home and whoever is in it from wherever you are. It also allows you to verify the cause of tripped alarms and coordinate appropriate resolution. This is one area where it is best not to scrimp on because the benefits far outweigh the added cost.

However, 24/7 security systems monitoring should be requested only when your situation really requires it; this will add a hefty monthly fee you would not have with simple remote access.

With careful consideration and a bit of common sense, you can find a security system you can afford.

interactive screens for education

The past decade or so has seen a lot of technological advancements in touch screens. These improvements have also resulted in significant reductions in the prices of touch screens. Now it is very common to see large touch screens used for many different applications, including sales, advertising, information kiosks, registration, etc. Interactive screens for education have the most potential to revolutionize learning. This site contains tips on using interactive whiteboards in classrooms.

How Do Interactive Screens For Education Help Students Learn?

Interactive touch screens are often used as digital whiteboards in many classrooms. Through these screens lessons which previously required reading from a book can come alive in the form of media content. It’s hard to find a kid who would rather read a book than watch a movie. In the same way, when lessons are given in the form of lively presentations or even videos, they attract more attention and interest than any textbook can. In fact students will love having to lug fewer books to and from school.

There is more truth to the statement that learning is a two-way process than most people realize. In the real world, hands-on types of training always trump lectures when it comes to lesson retention. When you use touch screens to teach, you allow students to physically touch the screen for their inputs. Interactive screens encourage students to participate actively in discussions, much more than they would when using ordinary whiteboards. Thus the instructor or teacher is able to draw out students’ ideas. Touch screens let the whole class take active part in the learning process. Students get the chance to support each other and learn the lesson together, which makes lesson delivery an immersive and enjoyable experience. Being able to relate the lesson to a positive experience also helps improve students’ retention.

It is also much easier to get students to collaborate on projects using touch screens. Traditional group project assignments can be hard on students; they may have to mess with lots of materials, perhaps even work on parts of it outside school hours, etc. With touch screen whiteboards, there are plenty of educational apps which allow students to collaborate on projects virtually; that means no mess, no work to take home, and immediate results. Whiteboard images can be instantly saved and printed for later review; students would not have to take too much notes.

The Benefits For Teaching Staff

Touch screens obviously make the job of teaching easier and more enjoyable. But there are other benefits to the use of interactive touch screens as whiteboards. Unlike real whiteboards, interactive touch screens do not require much maintenance; there are no surfaces to erase and clean up after each use. With large format multi touch screens you don’t really need most traditional multimedia equipment anymore. The room need not be cluttered with projectors, projection screens, VCR’s or DVD players.

Best of all you would be using cool new technology which students can readily relate to those on their smart phones. You use the touch screen’s natural wow factor to start your interaction with students in the right foot.
