IP video surveillance is a way for you to keep an eye on your home or business from a distance. It works by using a network of cameras that take pictures or videos and then send them to a special computer where you can view them from any device, like a computer, tablet, or phone. This is useful for keeping an eye on areas where you can't be, like when you're away from home or at work. You can set up the system to send you notifications when the cameras detect any movement, so you can be aware of any undesired events as they happen.
