Wireless home security systems use battery or solar power. They can cost anywhere from $200 to $2,000. Prices vary depending on the features and number of cameras installed in and around your home. These systems are much simpler to install, and you can control them with a smart device.

Not all security cameras require the internet, but without it, you miss out on remote control, notifications, and other features of smart cameras. While these days, most security cameras are connected to the internet, there are a number of wireless options that don't require the net to function.

Many people mistakenly assume that wireless burglar alarm systems operate using internet-like wireless frequencies, but this is not the case. Wireless alarm systems actually use much lower frequencies than the standard 2.4 GHz that is used for WiFi.
