While those are all essential components of home security, there’s more to the picture than that. With the best home security systems, you’ll also get monitoring services to keep tabs on your house from anywhere and various other features. Access control might seem like a strange feature for a home security system, but it’s essential for keeping unwanted guests out of your house. A typical system includes magnetic locks for all doors and windows and a keypad or card reader to enter the home. You can ensure that only certain people can enter certain parts of your home by assigning them different keys or codes.
