Security cameras can be a great addition to any home. They can be used to deter crime, monitor movement, and keep an eye on pets or kids while you are away.

Unlike wired models, the Best wireless security cameras are easy to install and can be moved around the house. They also have long battery life and record sharp high-quality video.

1. Look for a camera with a wide field of view

A wireless camera transmits data through radio waves, capturing and sending images over a secure connection to a receiver—typically a hybrid DVR or a smart device. The receiver can be accessed over the internet or via a wired Ethernet connection.

Wired security cameras are more reliable and offer a more stable signal, but require complex wiring installations. On the other hand, wireless options allow for simple installation and are less prone to interference from neighboring devices, although they can suffer from limitations of their own.

Look for a model with an impressive field of view, so you can easily monitor your home from all angles. Some models can even detect motion and send you smartphone alerts if it’s detected, as well as have speakers so you can communicate with anyone in the vicinity through your smart app—a feature called two-way audio.

2. Look for a camera with good resolution

In general, a higher resolution (measured in megapixels or MP) means more detail. However, the higher the resolution, the larger the file size, so it's important to find a balance between resolution and storage space.

Ideally, the security camera will be able to capture an image clear enough to make out license plates and faces. However, not all cameras can achieve this, particularly if the camera is recording 24/7.

Another consideration when evaluating resolution is your network's bandwidth and speed. A stable and fast network is critical to ensuring high-quality images and videos are delivered quickly. Wireless security cameras can be connected to your home's WiFi and stream live footage to your smartphone. Some also support smart features like two-factor authentication and geofencing. They can be plugged into an outlet or run on rechargeable batteries, and many are weatherproof.

3. Look for a camera with long battery life

Unlike wired cameras, wireless security cameras can be moved around the house without the need for additional wiring. They also connect to the internet via WiFi and can transmit footage to your smartphone. Some cameras plug into an outlet, while others run on rechargeable batteries.

Battery-operated cameras are easy to install and don't require an electrician, but they also need replacement batteries and can run out of power more quickly. Look for a camera with a long battery life, especially if you live in a remote area or have frequent power outages.

Some models use light amplification technology or infrared thermal imaging to improve visibility in dim lighting, but these features can drain the battery faster. Also, some models store video clips in the cloud, for which manufacturers typically charge a monthly fee.

4. Look for a camera with two-way audio

Security cameras with two-way audio can be a useful way to keep an eye on your property, especially when you’re away. They allow you to see and talk to anyone who comes up to your property, which can be helpful if you’re worried about intruders or want to check in with contractors working on your home or business.

CR recommends looking for a camera that can capture video at a rate of at least 24 frames per second and has night vision capability. Additional features like built-in sirens, monitoring zones and person alerts can be handy too. You’ll also want to look for a camera that offers either local or cloud storage. It’s recommended that you opt for the latter to save money on monthly storage fees.

5. Look for a camera with motion detection

Whether you want to scare off porch pirates or keep an eye on deliveries, wireless security cameras can be a helpful deterrent and provide peace of mind. But it's important to look for features like long-distance motion detection, night vision, and backup batteries when selecting a camera.

Smart wireless cameras connect to your home WiFi network and send alerts to your smartphone. Some have a plug-in base station that remains plugged in while others use rechargeable battery power to stay unobtrusive and can be moved around the house.

They also can integrate with your smart home ecosystem, allowing you to view and control them using voice commands with Alexa or Google Assistant (fewer work with Apple HomeKit). Some models allow two-factor authentication for extra security and privacy.
