Setting up your first home security system can seem intimidatingly complex. The first question you’ll likely ask yourself is, “How many security cameras do I need?”.

Security cameras are an integral component of any effective home security plan. Of the 1.4 million burglaries in America last year, 67.2% occurred inside residential homes. Cameras can deter burglars and help keep your house secure.

They provide home security, enable you to monitor your children and pets, and enforce house rules while away.

It would be best to have enough cameras to cover all corners for your home security system to be effective. You must decide what kind of camera and features they should include.

Indoor Security Cameras

Indoor cameras allow you to watch what’s happening in your home via live feed. They’re ideal for monitoring family members, pets, and sitters/nannies while you’re away. Recorded footage can be used as evidence that someone is breaking in, stealing from you, or vandalizing.

Night vision lets you watch what’s happening even when it’s dark outside. Your surveillance camera will activate only when motion detection detects action, and HD resolution provides a crystal-clear picture of what’s taking place.

For added convenience, consider making your indoor cameras accessible via an app. Ensure it has WiFi connectivity so you can easily sync with other devices.

Outdoor Security Cameras

These home security cameras are ideal for deterring criminal activity. An analysis of convicted burglars revealed that outdoor cameras could deter burglars, providing them with a risk they don’t want to take.

Video footage may also be used as evidence of vandalism or intrusion, helping authorities and you identify the perpetrators.

Outdoor cameras are not only beneficial for security, but they can also allow you to keep an eye on your family members and pets. You can keep tabs on children or animals wandering off into the unknown with outdoor cameras.

Outdoor cameras require the same features as indoor ones, including night vision. Motion detection helps the cameras capture any actions that take place outdoors.

HD resolution is essential if you want your evidence or feeds to be crystal clear. Your outdoor cameras must also be weatherproof and resistant to temperature changes and other elements like rain or snowfall.

Where Should You Install Security Cameras?

Before installing your home security system, the cameras must be placed strategically. Cameras should monitor areas where most activity takes place and those most vulnerable. Once you determine how many cameras you need, ask which sites they should be on for optimal coverage.

Front Door

Refrain from assuming that intruders always use side entrances to escape. According to statistics, 34% of burglars enter through the front door, often where package thieves strike out.

You can keep tabs on who enters and exits your home by installing a camera at its main entrance. This applies to family members, sitters, maintenance personnel, and others.

Back and Side Doors

Due to their often inconspicuous location, secondary doors can be vulnerable to unintentional entry. To monitor who enters and exits your house more securely, consider installing a security camera if secondary entrances are used more frequently than the main one. This way, you will always know who is entering and exiting your property.


Installing a camera outside your yard allows you to keep an eye on any intruders. You may also use it for monitoring children’s outdoor activities.

Garage and Driveway

This security camera system enables you to monitor vehicles, tools, and personnel handling them.

Connecting to the outside world with outdoor security cameras is easy. If your garage is part of your house, a video feed can be provided to keep everyone secure. In some cases, additional cameras may even be necessary at the gate to catch intruders as they enter.

Common Areas

With cameras installed in high-traffic areas like the kitchen or living room, you can monitor everyone’s activities. Check if your children are playing or doing homework and whether the babysitter is paying attention. You also can check on household repairers and helpers for added peace of mind.

Main Hallway or Stairway

Install cameras in all main areas of your home so that uninvited persons cannot avoid detection. Surveillance and detection systems will stop intruders who attempt to break in without being noticed.

Areas With Valuables

Consider installing an indoor camera in the area – including your primary bedroom- if valuables are present. This is where thieves often search for safes, jewelry pieces, and cash.

How Many Security Cameras Do I Need?

Your priorities and other factors will dictate how many security cameras you require. If you want to deter burglars and intruders, more outdoor cameras may be necessary. Conversely, if you wish to watch over family members, pets, and sitters inside your home, more interior cameras may be required.

Other factors to consider when deciding include the size of your property and home. More cameras may be needed for larger structures, and you should also protect any outbuildings with valuable items.

Here are some examples of cameras you might need for various areas:

You can add certain areas to your current set if they require additional cameras.
