It is hard to determine how much protection you need without over paying. Home security can be in the form of a security camera as well. You can post a security monitoring camera out side of your home so you can keep a clear visual when you are inside or a record if you are away. You can also post a security camera near your front door so that you can see who is at your door before opening it, or even coming down stairs for that matter. Having a security camera or a set of them installed strategically around your property can be a great convenience in a number of ways. If you have nice cars or items on your property such as tools you can use constant video surveillance that can be digitally recorded in case of the event of a loss or theft.
