Security Cameras to Keep Your Home Safe

Home security is a top priority for many homeowners today. With crime rates fluctuating across the country, many are turning to security cameras as an affordable and effective solution to deter crime and monitor their homes. This comprehensive guide will walk you through everything you need to know about installing, using, and maintaining security cameras to keep your house safe.


Home security cameras, also known as CCTVs or closed-circuit television, have become an increasingly popular home safety solution. Advances in camera technology along with WiFi connectivity and remote monitoring capabilities have made security cameras more accessible and useful than ever before.

What Are Security Cameras?

Security cameras are surveillance cameras used to remotely monitor and record video and images of a location. They can be wired or wireless and are composed of a camera, housing, lens, and recording device. The cameras connect to monitors or video recorders to view and record footage in real-time or when motion is detected.

Why Are Security Cameras Important for Home Safety?

Security cameras are an important part of a comprehensive home safety system. Benefits of security cameras include:

  • Deterrence of crime – Outdoor cameras visible to intruders may dissuade criminal activity.
  • Home monitoring – View live footage on smartphones to monitor children, pets, housekeepers, etc.
  • Evidence collection – Footage can provide evidence and aid police investigations.
  • Peace of mind – Security cameras allow homeowners to check on their home anytime for added comfort and security.

This guide will take an in-depth look at the types, features, installation, and usage of security cameras to help you choose and set up the right system to protect your home.

Benefits of Using Security Cameras

Installing security cameras provides many advantages beyond basic home monitoring. Understanding the benefits helps highlight the value cameras can add to your home.

Deterrence of Crime

Outdoor security cameras and warning signs can deter potential burglars from targeting a home. Many thieves seek vulnerable targets of opportunity, so visible security measures thwart unwanted attention. Outdoor cameras also hamper criminal activity in surrounding neighborhoods.

Monitoring of Home Activities

Cameras allow homeowners to monitor babies, children, pets and elderly relatives when away from home. They also provide oversight of housekeepers, contractors and maintenance workers that enter the home when unsupervised.

Evidence Collection

Security footage provides a record of events if a crime does occur. The evidence can help identify perpetrators and aid police investigations. Cameras can also exonerate innocent people accused of crimes.

Remote Access

Homeowners can check live feeds and recordings using smartphones and mobile apps for on-the-go monitoring. Traveling homeowners can peek inside to check on pets or just for peace of mind.

Added Peace of Mind

Cameras allow homeowners to verify their home’s safety at any time. Homeowners gain comfort knowing they can easily look in if they hear a suspicious noise while away or are concerned about severe weather threats.

Installation and Setup

Proper security camera positioning and setup is key to an effective system. Consider these factors when installing cameras:

Location Selection

  • Outdoor cameras should cover entryways, driveways, yards, and vulnerable areas like back doors or windows. Avoid pointing cameras at public spaces.
  • Place indoor cameras in entryways, atriums, hallways, and areas prone to intrusion like basement windows.
  • Don’t position cameras in private spaces like bathrooms or bedrooms.

Mounting Options

  • Outdoor cameras mount to eaves, soffits, exterior walls, or freestanding posts.
  • Indoor cameras can sit on shelves or side tables or mount to walls or ceilings.
  • Adjust viewing angle to best capture important areas. Point downwards at 10-15 degrees.

Power Source

  • Wired cameras use outlet power or low-voltage wiring from central unit.
  • Wireless cameras use battery packs or outlet adapters. Solar charging options are also available.


  • Wired cameras connect to DVR or NVR recorder via Ethernet or coax cabling.
  • Wireless cameras connect to WiFi network via router or mesh system.

Recording and Storage

  • Local DVR or NVR records from wired cameras and stores video internally or via external hard drive.
  • Cloud storage uploads recordings offsite via WiFi for wireless cameras. Cloud plans provide varied storage terms.

Maintenance and Upkeep

Regular system maintenance is advised to keep cameras functioning properly. Follow this basic maintenance routine:

Cleaning and Maintenance
