Wireless Security Camera Batteries: How Long Do They Last?

Battery equipped security cameras have made setting up our home security as convenient as it can get. But there’s a small catch. The batteries may die without you knowing. This results in you failing to monitor your properties using your security camera/system.

Imagine this. Your batteries have gone out of power. You’re not aware. Your house got robbed. When you investigate why your camera didn’t record anything, you find the battery is dead.

This is why you should be aware of how long wireless security camera batteries last.

This article will give you a general idea about wireless security camera battery life. I will also dive into the details of brand-specific wireless camera models.

Let’s get started.

Wireless Security Camera Battery Life

Wireless Security Camera batteries can last from 3 months to up to 3 years until they become unusable. In a more common scenario, the batteries can last from 1 to 3 years.

This can, of course, depend on your usage, the brand, and even the various models of the same brand.

Let’s look at some company-specific wireless camera battery life


Blink promises a solid 2-year battery life for many of its products. For the Video Doorbell, XT2, and Gen 2 cameras, are based on-

  • 43,200 seconds of motion recording
  • 5,882 seconds of Live View
  • 4,788 seconds of Live View with the two-way talk

For Gen 1 Indoor and XT cameras, these 2 years are calculated based on 40,000 seconds of Live View and Motion Clips.

In CNET’s experiment of Blink XT2, they found the security camera battery still going strong after 1 year.


Reolink states their security camera batteries can last from 2 to 6 months. Another battery life calculation they use is 500 charge cycles.

They also mention the single-charge battery life of some of their models.

  • Reolink Go: 1 – 4 weeks for normal use. About 10 hours in day mode and 7 hours in night mode if the IR light is on for continuous live view. 20 hours for day mode and 10 hours in night mode if the IR light is on for continuous playback.
  • Reolink Argus 3 Pro: About 4 weeks for normal use. In Reolink’s experiment, they got 960 minutes of battery life in the daytime and 540 minutes of battery life in the nighttime for extreme continuous recording.
  • Reolink Argus Eco: About 1 – 4 weeks per full charge.
  • Reolink Go Plus, Go PT Plus, Argus 2, or Argus Pro: 1 – 4 weeks


Most of Eufy’s camera batteries last for one year. The only exceptions they mention are eufyCam 2C and eufyCam 2C Pro, which have a battery life of half a year.

Their Video Doorbell 2K can last for 180 days for a full charge.

The usage conditions include –

  • 10 motion detections per day
  • Recorded for 30 seconds each time motion was detected
  • Standby power consumption is turned on when using


Arlo wire-free camera batteries can go for 3 – 6 months with normal use. The Arlo Go camera batteries can run out a bit earlier and last for 2 – 3 months with regular use.

This battery life is intended for optimized or best battery life settings. Arlo also assumes that you can record for about five minutes per day.


Kami says you can get up to 6 weeks of battery life on their Wire-Free outdoor camera, depending on how much you use the cam. Then you need to charge it.

This depends on-

  • Alert frequency
  • Traffic that the camera faces
  • Amount of trigger alerts
  • Uploading to the cloud or MicroSD card


Wyze mentions their wireless camera battery life as 3 – 6 months, after which, you will need to recharge it again. This is specifically stated for the Wyze cam outdoor.

How Do Wireless Security Cameras Get Power?

Wireless security cameras can receive power mainly in 3 ways –

  • Electrical Outlet: Believe it or not, wireless cameras may need to be “plugged in” for power as well. The reason they are called wireless is that they transmit data wirelessly.
  • Batteries: These are true wire-free cameras. They run on batteries. Some batteries are rechargeable while others are not. Battery life is an important issue for these cameras.
  • Solar Power: Set up a solar panel and connect the camera to it. The batteries get auto-recharged from solar power.

Factors That Determine A Wireless Camera’s Battery Life

All this time, you may have asked yourself about the reasons why the battery life varies so much and why they can be reduced. Let’s find out about some of the main components that affect a camera’s battery life –

1. Battery Capacity

Your camera battery life solely depends on its capacity. So what is the battery capacity? It’s the amount of charge contained in the battery.

When buying a wireless cam, you can check the battery capacity in the Power specifications.

Wireless Camera Battery Capacity

Battery capacity is measured with the mAh or milliampere-hour unit. If the batteries have more capacity, they will naturally last longer.

2. Usage

How and how much you use the camera can drastically improve or harm its battery life.

If you’ve maxed out all the settings, are continuously recording, constantly using the live view, then your battery will die rather sooner.

Using extreme configurations instead of stable and optimized ones can reduce the battery life from months to weeks or even hours.

3. Temperature

Every security camera has an operating temperature level. If the temperature of the area where you’re living is too low or too high than that, this can cause a faster battery drain.

Temperature is one of the controllers of chemical reactions. This means that temperature can either boost or hinder the battery’s performance.

4. Signal Strength

Wireless security cameras transmit data through waves. If there is a long distance between the receiver and your camera, then your camera will require more power to send data.

This is why it is very important that when you’re setting up your camera system, you keep the receiver close enough to the camera. Also, try to remove any kind of obstacles between the two devices.

5. Night Mode

You might have noticed from the battery life comparisons that cameras last shorter at night.

Because of the low light environment, the IR sensors of your security camera needs to work harder to detect object and motion. This drains more battery out of your camera than it does in the daytime.

Tips For Saving Wireless Security Camera Battery Life

We won’t leave you without sharing some valuable tips that you can use to save your wireless security camera’s battery life

  • Buy high battery capacity cameras.
  • Try to go for rechargeable battery cameras.
  • Place your camera near the router for easy data transmission.
  • Avoid high-traffic areas unless it’s necessary.
  • Optimize recording settings to minimize battery drain.
  • Use the battery-saving mode.
  • Keep the surroundings of your camera well-lit at night.
  • Keep the security system firmware up to date.


What Types of Batteries Are Used in Wireless Security Cameras?

Most battery-powered cameras operate on lithium-ion batteries. Lithium-ion batteries are quite stable. They are good for fast charging and lasting a long period. High power density causes the battery life to extend well.

How Often Do You Have To Charge Wireless Security Cameras?

This heavily depends on your usage and the power capacity of the battery. As I’ve mentioned earlier, some brands offer rechargeable batteries that can go 3 months or more if you use them moderately. In fact, you may not want to recharge the batteries too often as it may ruin their health.

Do Wireless Security Cameras Need Charging?

If your wireless security camera is using rechargeable batteries, then yes, they need charging. On the other hand, you never need to if your camera has batteries, these are not rechargeable.

How To Know When I Need To Charge The Wireless Camera Batteries?

Rechargeable battery powered cameras are a great choice if you want to have a long battery life in the long run. Many cameras with rechargeable batteries have an alert function. If the battery is too low, it will notify you for charging.

Final Thoughts

Now that you have a clear idea about your wireless security camera’s batteries and how long they last, you can take corrective measures to keep them healthier and make them live longer.

Proper maintenance of your surveillance cameras and their parts will make sure they serve you right. If you’re buying a new wireless cam, you can use this article as a guide to get a camera with the best battery features.
