In a world of 3G, 4G, and mobile hot-spots, DSL, cable, and braodband, it’s easy to get caught up in acronyms without actually knowing which method is the best connection. Any portable internet enabled device that supports 3G or 4g broadband connection and Wi-Fi (like the Yardcam) actually has three different methods of accessing the internet.

Wifi connection to wired Access Point.

The first method is a true Wi-Fi scenario in which a physical cable from the Internet Service Provider is attached to a wireless router. The router in turn broadcasts the signal to any Wi-Fi enabled device in its proximity, such as a camera. When you access Wi-Fi in your office, you are connecting to the same connection that a wired device would, but in wireless form. If you are connecting to Wi-Fi at a public “hot-spot” like those offered at coffee housess or libraries, you are sharing wireless broadcast of a wired Internet Service Provider connection at that location. Unlike the office, “hot-spots” at these locations do not offer the same protection that the secure, firewalled environment at your office most likely provides. It therefore behooves a user to limit public Wi-Fi usage to non-confidential information. That is not to say that every time you open a document your information will be stolen, just that you are more vulnerable to security threats at public locations.

Portable Internet

When using a 3G enabled device like a smartphone, tablet, or the Yardcam, which are not connected to Wi-Fi, the devices are connecting to the internet though a cellular connection. Instead of receiving a signal from a wired Internet Service Provider, the device receives data from a cellular company in the same way it receives a mobile phone connection. 3G as it is called, allows a user to access internet anywhere they receive signal, eliminating dependence on public “hot-spots” for mobile access. Unfortunately, this method is normally noticeably slower than a Wi-Fi connection. Though it is safer than a shared public “hot-spot”, it is not as safe as the firewalled environment in an office or home computer.

The Yardcam uses uses a portable Internet connection which allows the camera to be installed outside of Wifi range, which is usually about 100 feet or so. Walls, trees, bushes, fences, and moving objects will shorten this distance considerably, It is truly portable. You can unplug it at onr location and plug it back in a thousand miles away and it will automatically connect itself.
