10. Monitor your home
If you want to keep an eye on your home or office, your Wi-Fi network can be the key to your security needs. By adding a so-called IP camera, you’ll be able to monitor your property either from a device on the same Wi-Fi network or via the web.
Most cameras can send you an email if motion is detected. Although wired network IP cameras are still available, they’re not ideal in many cases. Models with built-in Wi-Fi start from about £35; if you want a high-quality picture with sound, you should budget for at least double this. For extra features, such as motorised pan and tilt (even zoom), prepare to spend hundreds.
Wi-Fi IP cameras differ in their resolution but, in reality, if your application is purely surveillance, the VGA resolution of 640x480 should be adequate.
More important is a remote-controlled pan-and-tilt capability, which will allow you to look around a whole room from a single viewpoint. You can now get this functionality in even some entry-level products.
Something else to look out for and, again, for which you don’t have to pay a fortune, is night vision. This is provided by a ring of infrared LEDs around the lens.
A waterproof housing for outdoor use will command a substantial price premium. Some manufacturers, including Y-cam, provide free apps that allow you to easily view the video feed on your smartphone or tablet via Wi-Fi.
