How Do Wireless Security Cameras Work 2022?

Wireless security cameras are a popular choice for many homeowners and businesses. They offer a number of benefits over traditional wired security cams, including easier installation and increased flexibility in where they can be placed. But how do wireless security cameras work? Check out our post.

How Do Wireless Security Cameras Work?

how Wireless Security Cameras Work

Wireless cameras work by transmitting the video of the camera through an RF transmitter. The video is sent through a radio transmitter to a receiver connected to either a built-in storage device or cloud storage. You’ll be able to view all your video clips and images through your receiver or monitor.

You will need to connect them to power outlets for wireless cameras to function. They do, however, require cables. Only “wireless” cameras don’t require wires. Wireless cameras can communicate without wires.

Let us explain. Most Security cameras can send and receive information via incoming and outgoing messages.

Cameras can receive instructions from the user in incoming messages. For example, you might use your smartphone to move cameras around or adjust their view angles. An additional component of your security system may also send instructions to the camera.

For example, if you have motion sensors connected to your cameras, these sensors can notify the cameras to start recording when they detect movement.

Outgoing messages: Security cameras can also send information. They transmit video. You may be able to receive the video directly via a live stream from your mobile device. They may also send the video to professional monitoring services or cloud storage to allow you to save the images for later reference.

Through a network of cords, wired security cameras communicate with each other and with other components of your security system via cables. On the other hand, wireless cams use one or more of these wireless technologies.

WiFi: Wireless cameras communicate with each other via WiFi networks. This setup allows cameras to communicate with each other and devices outside the home. Cameras can use WiFi to send video to DVR units in the area or to cloud storage. You can also have that video sent to them, no matter where you are in the world.

Cellular: Most home security systems used landlines in the past. It is understandable that most of the best no-landline security systems today still depend on some phone number or connection. These connections can now be wireless and make use of cellular networks. However, wireless cameras are less common than WiFi, many cameras that use WiFi use cellular connections as a backup. WiFi is not always reliable.

Bluetooth: Bluetooth uses the same frequency as WiFi but connects directly via star topology. Bluetooth can only work over short distances because it uses star topology. One controlling device is paired with up to six other devices.

Bluetooth cannot be used to transmit video from security cams outside of the home. If you are not nearby, the cameras can’t be sent instructions. The cameras can connect to security hubs via Bluetooth. If the hubs have an internet connection, the cameras can send signals to the outside world.

Zigbee/ZWave: Zigbee and Z-Wave are two other wireless communication technology that security cameras might use. Engineers created these technologies to enable smart home devices to communicate. Z-Wave and Zigbee do not have sufficient bandwidth to transmit video.

You can only use them to link your home security camera system parts together. Z-Wave and Zigbee security cameras must use other wireless technology to function correctly.

Wireless vs. Wire-free

Comparing wireless security cameras with wire-free cams can help you understand them better. Wire-free cameras don’t require external power sources. These cameras instead use their own batteries to power themselves. They can be “wireless” and have no wires.

These cameras are wire-free, but you cannot set them up for continuous video recording, as they lack enough power to record for long periods.

Wireless vs. Wired Systems

Wireless security camera vs. Wired Systems

Wireless and wired security cameras can capture and transmit video. However, they each have their strengths and weaknesses, so you need to think about which one is best.

Wireless Camera Systems


  • They are simple to install.
  • They are simple to use.
  • They include advanced features such as machine learning.
  • Even without a security hub, you can view the footage from anywhere.


  • They rely on WiFi signals for their work.
  • Clear images can only be transmitted if there is a lot of bandwidth.

Wired Cameras


  • They offer crystal-clear video.
  • They are impossible to jam.


  • Sometimes a wire can get messy.

A security hub with internet capabilities is required for wired cameras to transmit data outside the home.

FYI: Most wired security cameras use wireless technology, despite their name. For example, to transmit live video to your smartphone, a camera must connect to the internet or send signals to security hubs connected to the internet.

Wired cameras are better for people with poor WiFi signals or are particularly concerned about reliability. However, wireless is the best choice for those who want simplicity and convenience.

Different Types of Wireless Security Cameras

There are three types of security cameras available, each slightly different function.

Outdoor cameras: These cameras are installed on your exterior. These devices provide images of any person or thing moving within your home’s perimeter. Outdoor cameras are not recommended for apartment dwellers. They come with IP ratings which indicate how much weather they can withstand.

These devices must have an IP rating of at least 65 to ensure they are dust-tight and can withstand water spraying from a nozzle. Many homeowners conceal outdoor cameras to make it difficult for thieves to disable them.

Indoor cameras: Also known as “nanny cameras”, indoor cameras are installed inside your home. These cams let you know when someone is trying to enter your home or apartment. Some indoor cameras can be mounted like outdoor cams, while others are placed on flat surfaces.

Doorbell cameras: Since they guard your primary entry, doorbell cameras are one of the most widely used home security devices. Video doorbells are usually placed on the exterior of your home, right next to your front door. They allow you to view what’s going on at your doorstep.

FYI: Doorbell cameras technically aren’t wireless cameras. They can draw power from either a battery or from the wiring in a home to be either wired or unwired.

Wireless Home Security Cameras: Does it Work?

wireless security camera: Does it work?

Protecting your home is easy with wireless home security cameras. You can get alerts from motion sensors, window sensors and glass break sensors if someone attempts to enter your home. But security cameras only let you see what’s going on so you can deter criminal activity.

Wireless cams allow you to view live images and record video. Recordings can be vital for police to track down home intruders and serve as evidence when recovering stolen property.

Wireless security cameras aren’t required to capture any footage to be effective. They can deter criminal activity just by being present. According to the University of North Carolina Department of Criminal Justice & Criminology, the presence or absence of a camera was a significant factor in burglars entering a home.

Wireless Home Security Cameras: Who Does it Matter?

Wireless security cameras can be used by anyone but are particularly useful for those in the following groups:

Renters: Renters require surveillance systems just as homeowners do. There are many security systems available for renters. Security systems are available for apartment dwellers, too. Your landlord won’t let you tear down walls to install a hardwired system. Wireless camera systems can be installed without any permanent modifications to the property.

Landlords: You might think about installing wireless security cameras to ensure your tenants are protected. Wireless security cameras are simple to set up and can be moved quickly to accommodate tenants. Wireless cams offer security without bulky equipment that could ruin your property’s curb appeal.

Families: Security cameras can be used to prevent break-ins. They can be used to monitor your family’s health while you are away. Two-way audio allows you to soothe a crying baby or let an injured parent know that help’s on the way.

Smart homeowners: Smart homes can be wireless. Unlike wired cameras, wireless security cameras can communicate directly with the internet of things (IoT). Your house can talk to your security camera system, and you can use voice commands for zoom adjustments, repositioning, or pulling up footage on your TV.

Your bright lights can be programmed to turn on when your cameras detect motion on your lawn. Find out how to create a smart home.

Wireless cams are great for anyone looking to expand their security system.

Buying Wireless Home Security Cameras

Buying Wireless Home Security Camera

The first decision is whether to buy a wireless or wired security camera. The next step is to decide which camera brand and model to purchase. This decision will require you to take into account many factors.

Motion detection: Your wireless security camera can start recording when it detects movement.

Cloud storage: Some wireless security cams come with DVRs, but most of them now record directly into cloud storage. You can view your videos anywhere, anytime. This extra storage will cost you, so think about the costs.

Remote control: Remote control allows you to view live images on your smartphone, adjust the lens, and reposition your camera.

Lights: Wireless security cams often have lights. These lights can be motion-activated LEDs that are bright enough to guide you in the dark. Floodlights and flashing alarm lights are also options for cameras. If you are looking for an outdoor wireless camera that can be used with a spotlight, check out our Ring Spotlight Cam Battery Review.

Two-way Audio: This is a handy feature for wireless doorbell cameras as it allows you to talk to anyone at your door. Even guests can speak to you at the door even if you are not there, giving them the feeling that you are home.

AI: The more intelligent your wireless security camera, the less you need to worry about security at home. Smart wireless cameras can distinguish between different types of moving objects. They won’t notify you just because a squirrel passes but will inform you if there is a prowler in your yard.

Smart integration: You’ll need to integrate your security camera system with Alexa and Google if you want to make your home smart. You can use your voice to control your wireless cameras the same way you handle intelligent lights or smart locks.

App: A mobile app may not be necessary if you install wireless cameras as part of a home security system. An app is helpful if you are installing the cams yourself. It allows you to adjust, stream live feeds and review recordings.

Video specifications: It’s essential to see your camera’s video. An intruder can’t be recorded if it just appears as a blurred blob. Pay attention to video resolution and field-of-view. We prefer at least 1080p HD resolution. However, we are most happy with 4K security cameras. We insist that the field of vision is at least 120 degrees. Also, test the camera’s night vision capabilities and determine if it can focus on particular activity areas.

Prices: Last but not least, price is a consideration when it comes to security cameras. Wireless cameras such as Wyze can be as low as $20. Vivint’s Outdoor Camera Pro costs $399. This is primarily due to the features that each camera offers.

An excellent wireless camera should cost between $100 and $200. Please read our Wyze camera review and our Vivint Outdoor Cam Pro review for more information. You can also dive into the costs at our Wyze pricing page or on our Vivint pricing webpage.

Installation of Wireless Security Cameras

Although some people are hesitant to install security cameras, it is possible to do it in minutes and doesn’t require any tools.

Install the Cameras

You might need to place indoor cameras in flat areas and plug them in. Mounting your cameras is a little more complicated, but the process is still simple.

  • You should mark the areas where you intend to install security cams.
  • Locate the screws in the packaging of the security camera.
  • Attach the camera to the ceiling or wall using a drill and screwdriver.
  • Connect the power cord to the outlet.

Decide Where To Place Cameras

Most likely, most of your installation time will be spent selecting locations for your cams. You should keep in mind some things as you work through the installation process.

Power sources: Wireless cameras do not require wires for communication, but you will need to plug them into power outlets.

Hubs: Make sure your cams have a hub close enough to communicate.

WiFi: WiFi cameras must be within range of your router to receive strong signals. You should do the same with other types of wireless technology. For instance, for Bluetooth, the devices dependent on the controlling device must be close enough to allow them to connect.

First floor: If you have more than one-story homes, put indoor cameras on the top floor. This is where burglars most often enter.

Chokepoints: Install indoor cameras at choke points. These are places where burglars must travel to reach one area of the house.

Corners: Indoor cameras placed in corners provide the best view of a room.

Outdoor cams should be placed at the entry points. Begin with the front and rear doors. If possible, add off-street windows.

Direction: Make sure that your outdoor cameras point at your property. This will ensure you don’t record your neighbors and make your security cameras illegal.

Do You Need Professional Installers?

Wireless security cameras have the advantage of being easy to set up. For example, you don’t need to reach the wiring in your home or open walls. It’s as easy as plugging the cameras into power outlets.

If you’re installing cameras in difficult-to-reach places, such as outside second-story windows or other areas, you may want to hire a professional.

Can You Install Wireless Security Cameras in Apartments?

Wireless security cameras are great for apartments because of a variety of reasons.

Equipment: A doorbell camera is not necessary. Your front door should be your only entry point if you live on the second floor. You may consider a Ring Peephole Cam if your front door has a peephole.

Installation is easy: Indoor cameras can be installed without hardwiring. You can place multiple wireless models on flat surfaces. You can simply place them on a flat surface and plug them in.

No structural changes are required: Wireless cameras won’t force you to modify your apartment.
