Communication is initiated from the gate station by selecting a 3 digit code such as 001 or 901 and pressing the # button. Only the selected houses handset will ring and communication is established. Communication is simplex so only one person can speak at a time but the gatestation’s microphone is always active so the visitor does not have to press any key to speak. The inside handset can enter into the conversation at any time by pressing a PTT button.

Multiple handsets can be added for the same house to have internal communication. There is a handset calling button which works on push-to-talk.

An extra gate station (back gate station) can be added for instance on the inside to notify houses when the visitor is leaving or on additional gates. All the same handsets can be called. Gate opening is only possible from a back gate if a call is in progress.

Programming is done manually or via PC. Programming mode is protected by a pin. Names and numbers are entered with the keypad. The PC programming kit is needed for large systems or when a back gate station is used.

Posted by Enenim Asukwo Bassey.

In an online applications, most of the heavy processing is handled by the service provider, which minimizes the requirements on your system configuration. Desktop applications require high memory and processing speed for complex applications like graphic design. The advantage of the desktop application is its independence from internet connectivity and bandwidth considerations. Online applications rely upon the internet infrastructure for data transport and content rendering. Desktop applications offer higher security than online application as it is free from malicious activities of the so-called bad guys and possible virus attacks. Online application can be very frustrating especially when internet connections are slow or unavailable but this is not the case with desktop application.

Why use an online business directory?

Contributor: Adesina Adeola of Covenant University, Ogun State, Nigeria

As the owner of a business, you want to get your business maximum exposure and on a limited budget. The world of business is changing and tilting more and more towards online commerce and advertising, so now is the perfect time to begin gaining an online presence.

Unlike a local business listing, Online business directories will allow your listing to be seen anywhere in the world. This is important, especially if you want to build an international brand. Large global corporations spend hundreds of millions, if not billions on advertising, but you can begin with a free listing and be well on your way to having an online, global presence.

Having a website is a great way to help people find your business but it is often difficult to be recognized by Google and to be placed high in the organic search rankings. Being listed in a directory can help immensely. By being listed, Google will see a link from the directory to your website, this is called a backlink, and it will make your website appear more credible to Google. The more backlinks you have, the more likely Google will list you higher in their search rankings, which can make your website much easier to find and give it significantly more traffic, which in turn attracts more customers to your company.

Also, by being listed in an online directory, people who are looking for your product or service can find your website or contact information through the online directories. Directory listings often come up high in search engine rankings so your listing may appear right near the top, ultimately bringing those people to your website.

So now you can take the first step towards maximizing your web presence and you can do this by submitting your business website to any directory service of your choice so that it can be promoted and advertised globally over the internet.

Why Should Schools Have Their online Applications and their students IT equipped

Composed by Enenim Asukwo Bassey (Unilag)

It has been challenging for schools to manage/store information about their students and staff using the manual files system, especially keeping and maintaining  records of their ex-students and staff, which keeps accumulating year after year. Also, these invaluable records are at risks of  fire outbreak and other unforseen future disasters. These problems and many more can be avoided if records are kept online. 

Also graduated students can go online and print out their testimonials,certificates,results and other credentials. All they need to do is to provide authentication as required by the school administration. Furthermore, knowledge of IT has become so indispensable that students and staff are to be provided with the adequate skills regardless of their interests/discipline. 

Now that you know how useful it is to have your school online application and the need to equipped your students and staff with IT knowledge,the question that arises is where and how to acquire them - the answer, HISPLUS' School Nigeria.
