Home Security Camera Buying Guide

With the increasing need for home security, choosing the right home security camera that meets your specific security needs is essential. However, the challenge lies in the abundance of models available in the market, leaving homeowners needing clarification on the factors to consider when purchasing. This buying guide aims to tell you how to choose best home security cameras and help you understand their different types, innovative features, and installation considerations.

Why Need Security Cameras for Home?

Security cameras are essential for your property for several reasons. You need to buy security cameras for your property for several reasons. First, visible security cameras can be a powerful deterrent to potential burglars and intruders. If they notice the presence of these devices, they may think twice before attempting break-ins or vandalism.

Secondly, security cameras can record events and incidents and provide crucial evidence in case of a crime, accident, or dispute. This documentation can be valuable for insurance claims and legal purposes. Most importantly, home security cameras can help ensure the safety of family members, particularly children, older people, or individuals living alone. They allow you to check in on loved ones and respond to emergencies.

Guide to Choosing Home Security Cameras: Key Factors to Consider

When choosing the security camera for your home, you need to consider several factors to ensure it meets your home defense requirements.


The first thing you should decide is the number of security cameras needed for your home. You should check the size of your property before purchasing. In most cases, larger properties may require more cameras to cover all entrances, windows, and outdoor areas adequately. In contrast, smaller properties may need fewer cameras. Consider the security camera system your first option if you need multiple cameras.

Video Quality

Consider the captured footage's clarity. The video quality of modern security cameras is measured in resolution. Higher-resolution cameras produce sharper and more detailed images. Clearer footage will allow for better identification of individuals or objects within the video footage.

Field of View

The field of view (FoV) of modern security cameras represents the area the camera can capture in a single frame. A wider FoV may capture more space, but it might sacrifice detail, while a narrower FoV may provide more detail in a specific area but cover less overall. Common FoV ranges for fixed-lens cameras are between 70 and 120 degrees. And wide-angle cameras have FoVs ranging from 100 degrees to 180 degrees or more.

Night Vision Capability

Effective home defense should not be limited to daylight hours. Therefore, you should also check the night vision capabilities of the chosen model. Cameras equipped with infrared (IR) LEDs can capture clear footage even in low-light or complete darkness, and some advanced cameras also can capture colors at night.

Recording and Storage Methods

There are two standard options for modern security cameras to record and store video footage: local storage and cloud-based storage. Local storage options for home security cameras without subscription include SD card, Network Attached Storage (NAS) devices, external hard drives, and Network Video Recorder (NVR).

Cloud-based storage means storing the footage on the remote cloud server, and you can access the video clip from anywhere with an Internet connection. But in most cases, cloud storage requires a subscription plan, which may increase your budget.


To realize the daily monitoring and control of your camera, you'd better choose a brand that has its proprietary app. The compatible app lets users conveniently manage and interact with their security cameras using smartphones, tablets, or other mobile devices. You can watch the live video streaming, play back the recordings, and adjust camera settings via the app.


The price will also significantly affect choosing your security cameras. The general rule is that high-quality cameras will cost more, and you must balance cost and coverage. You can set a budget plan before buying.

Placement and Installation

You also need to consider the optimal locations for camera placement and installation. Ideal areas to place security cameras include the front door, back door, garage, driveway, living room, kitchen, and any other areas of security concern. You can choose easy-to-install models, such as wireless home security cameras if you have no installation expertise. The installation of PoE cameras and NVR may require extra time and effort.

Types of Home Security Cameras

Home security cameras can be classified into different types based on specific criteria and have undergone various evolutions. Here are some typical criteria.

But if you search on online shopping platforms, like Amazon or eBay, you can find offerings under $50 and some high-end models over $300. Security camera systems range from $200 to $800, depending on different models and brands.

If you hire a professional team for camera installation, it will cost about $100 more. However, you can install the camera yourself, and all you need to do is gather some necessary tools and read the installation instructions before starting.

Home Security Camera Placement and Installation

If you already have a security camera or are still looking for an ideal model, you may be aware of their ability to deter break-ins and safeguard your property. Nevertheless, the proper placement and installation can significantly impact its effectiveness.

The ideal placement of security cameras in and around your home depends on your specific security needs and the layout of your property. In most cases, security cameras should be placed at vulnerable entry points of your property or some high-value spots. Here are some familiar places to position your security camera for home.

  • Entry Points: You can place security cameras at essential entry points of your home, such as front and back doors, side doors, and garage doors. These are potential entry points for home intruders; for example, statistics show that 34% of burglars enter homes through the front door.
  • Windows: Consider placing cameras near ground level or above off-street windows to avoid potential vandalism. But remember that putting security cameras behind glass windows may result in blurry images or inefficient motion detection. So, it would be better to put cameras outside your window.
  • Backyard and Garden: If you want to keep an eye on your garden grow and watch wildlife, you can place security cameras in your backyard and garden. Choose weather-resistant models for these outdoor spaces and add floodlights to illuminate the area if necessary.
  • Driveway and Parking Area: If you have a driveway or parking area, consider installing cameras to monitor vehicles and individuals approaching your property. These visible devices can help with both security and surveillance.
  • Staircases and Hallways: For indoor security, consider placing cameras in hallways and staircases, which are common routes for intruders within the home. With the help of indoor security cameras, you can also monitor your children's or parents' daily activity.

Installation Tips

Installing a security camera at home is easier than you thought. Here are some installation tips you can use to maximize its effectiveness.

  1. Mount the camera at a certain height: For outdoor cameras, mount them 8 to 10 feet above the ground. This height is ideal for capturing more details while avoiding easy tampering. Indoor cameras should be placed at eye level, around 7 feet above the floor, to capture clear images of individuals.
  2. Adjust the angle and position: You can angle the camera slightly downward to avoid pointing it directly at the ground or too high in the sky.
  3. Avoid glare and reflections: Protect your cameras from reflective surfaces like windows and glass doors. The glass can cause glare and interfere with the camera's view.
