With crime rate already on the rise in Tagbilaran City, video surveillance has become a necessity for many businesses and homes to help deter attacks from criminal elements and prevent employee pilferage of company materials and inventory. You bought the video cameras that record the data digitally on your computer. Now what should you do next? It is now possible to view the monitored areas remotely using the Internet as the “path” for the data. A business owner travelling in Manila can open his browser on his laptop, connect to the Internet and then open up the camera’s IP address to view the video stream. However, not all Internet access services will work properly with video stream. An important thing to note is that published bandwidths of most Internet subscriptions are for the download data traffic. Upload traffic is normally very small compared to download traffic. Video cameras upload the video data so at the camera location, you need to get an Internet access service with data rates for upload and download are the same and if you foresee that you will be viewing the video stream for 24×7, you need to get dedicated Internet access service. Otherwise, the video, when viewed remotely, will be very choppy. It is also possible to avoid using the Internet for the video stream path as long as you are able to deploy your own branch office connections within Tagbilaran or subscribe to wide area network services that may be provided in your area. A local area interconnection service will provide a very low latency from the server location to the client...

Probably one of the commonly used yet most misunderstood technologies is the Internet. And perhaps its most misunderstood element is the capacity of a user’s Internet access subscription often termed as Internet Bandwidth. With the proliferation of Internet access services priced at around Php1000 per month or even lower with bandwidths published as “up-to” 2MBPS or even higher, many frustrated users ask why is a 2MBPS connection still slow to load a normal webpage? Internet connection from the Philippines going out to the world is done through submarine fiber optic cables going from the Philippines to Taiwan, Hongkong and other countries that serve as hubs for interconnections. Just image the cost of laying out thousands of kilometers of expensive cables submerged into deep ocean, then include the cost of operating it and repairing any cable faults. That’s not going to be cheap to use this interconnection service. The very large bandwidth specifications published by many Internet Service Providers, including telcos like PLDT, Smart and Globe, is generally a marketing ploy. It gives you an illusion that your connection is going to be very fast. And this is true, when you are the only one using it. When you look at the fine print, most likely you will see a zero committed information rate or CIR, which technically means they are not committing to any service rate at all. So in order to be able to offer Internet access at Php1000/month given that the international connections is expensive, the service providers “share” the connection among its subscribers. A 2MBPS connection with zero CIR is probably shared by a hundred or...
