The main purpose of a surveillance system, for a home, is to push your security perimeter outside the home. You want to be alerted to the presence of a dangerous or unwelcome individual, far before they enter your family's living space. Windows that can be broken into windows that are small enough not to fit a person or which have bars on them can, sometimes, be ignored. A Garage door is often forgotten as a potential entrance for your home.

You should have cameras in front of your garage door and inside your garage where your garage opens to your home. Outdoor places where your store expensive items like your parking spot, tool shed, and pool areas should also be covered. Areas where employees work should be recorded to monitor productivity and to reduce the likelihood of workplace violence, bullying, employee policy violations such as not following important safety procedures and sexual harassment and to provide evidence in the case of any false claim such as workman's comp fraud.

Places where you store product or money especially cash registers and warehouses, but also all retail space should be recorded to reduce the likelihood of theft and shrinkage. You also want to monitor for things like water leaks or other environment damage that can ruin your investment. Areas where customers are present should be recorded to monitor staff customer service level engagement with customers, as a protection from false claims like slip-and-fall fraud , to protect employees from consumer-on-employee violence or harassment, and customer-to-customer arguments and assaults.

Also, just like a home, you want to push your security perimeter as far outward as possible. So, you still want to monitor all entrances windows and doors to your property. Some areas where your security camera system will be located simply do not need to covered or, legally speaking, should not be covered. In a home , most people do not worry about the sides of a home, if there's no way of getting into the house doors or windows.

Many people also consider the indoor areas of a home to be private and can also be omitted, if you create an effective security perimeter. A security perimeter is only useful if you are only allowing secure individuals inside it , however. If you have in-the-home activity that requires accepting semi-trusted individuals into your home, you may want to install cameras indoors. For example, if you believe that you or your loved ones are at risk of elder abuse or the abuse or neglect of a child by an in-home caregiver, such as a nanny or medical aide, or are worried that your cleaning company may be stealing from you.

Please be aware that installing security cameras in a place where people have an expectation of privacy can be illegal and result in fines or criminal charges.

Under no circumstances, should you use security cameras to monitor a bathroom or to record areas where you expect sexual activities to occur.
