Choosing a battery operated security camera with motion detector can be tricky.

Some battery powered motion activated CCTV cameras alert you in real-time when human movement is detected, while some send tons of false alarms each day or can't even send any alerts.

If you are in the market for a battery powered motion detector CCTV camera, read this guide to set yourself on the right path.

How Battery Powered Motion Activated Security Cameras Work

A battery powered motion activated security camera uses PIR (Passive Infrared) sensor to detect changes in the surrounding area's ambient infrared radiation.

When a human or animal body gets in the range of the sensor, the battery operated motion sensor security cameras can sense the infrared energy and trigger instant alerts, like smart siren, email snapshots and push notifications.

Normally the high quality battery motion activated security cameras will allow you to enable or disable these alert options via the camera app, so that you can customize an alarm mode that suits you most.

Unlike the pixel based motion detection, which compares the changes in pixels from one frame to another, the battery operated security IP camera with PIR motion sensor measures infrared light emitted from objects that generate heat.

Working in this way, the battery powered motion detection security cameras can greatly reduce the false positives from wind in the trees, shadows, etc.

Motion Detection Modes How It Works Applications
PIR motion detection Detect the infrared light radiated by a warm object Commonly applied to the battery powered security cameras
Pixel based motion detection Calculate the differences between consecutive frames Widely adopted in the non battery security cameras & systems

Factors to Consider Before Buying Battery Operated Security Cameras with Motion Detectors

Before you buy a battery powered motion activated security camera, make sure you have considered all the following important factors.

1. False Positives

Don't want too many false positives from your battery powered motion sensor IP camera?

Check if the battery operated security cameras with motion detectors allow you to adjust motion detection sensitivity. The less sensitive the motion detection is, the battery powered motion IP camera is less likely to trigger alarms.

Over time, you will find the exact sensitivity in the motion detection battery powered camera that works for your particular location and situation.

Another method to reduce false positives is to place your battery operated motion activated CCTV security camera in a proper spot. If possible, do not allow any moving items to remain in an area where the PIR motion sensor is located.

False Alarms of Battery Powered Motion IP Camera

2. Scheduling

The scheduling feature of battery motion trigger security cameras allows you to set the specific time for motion detection and alert notifications.

This is particularly useful when you only want to be notified in certain situations, say, when you are away from home or when your kids come back from school.

It can also reduce the unwanted alarms of your battery control motion activated security cameras and save recording space.

3. Local Recording

Some battery powered motion activated security cameras are equipped with an SD card slot. If so, you can save the motion triggered events directly on the battery operated motion detector security camera with SD card.

And the battery powered motion activated security cameras with memory card can also eliminate the monthly storage fees (See more home security systems without contract and monthly fees).

4. Resolution

The recorded videos are of little use if they are blurry or distorted, so look for a battery powered motion detection security camera with highest possible resolution that can provide you with more details, like the license plate numbers and human face features.

Now most battery control motion sensor security cameras display 720p images and videos, but some have led the way and come out with 1080p resolution, such as Reolink Argus® 2 and Reolink Argus® Pro. (Click here to learn more about the high resolution battery operated motion security cameras.)

Below is a video shared by a real user of Reolink Argus® 2.

5. Alert Options

When the battery powered motion aactivated security camera detects any human movement, you certainly want to be alerted in real time.

Some top battery operated security cameras with motion detectors, like Reolink Argus® 2, offer multiple alert options, including the voice alert, emails with snapshots and push notifications to your phone.

Besides that, the 4G/3G battery operated security camera with motion detector Reolink Go, also allows you to record your own alert message, so you can get notified with it when motion is detected.

6. Night Vision

Whether you want a battery operated security camera with motion detector for home or for cars, clear night vision is a must-have feature for the battery powered motion activated CCTV security cameras.

Now some battery powered motion security cameras even provide starlight night vision by utilizing the cutting-edge image sensors, like Reolink Argus® 2, which take the image quality in low-lit conditions to a new height and allow for color video recording as well.

Say, you want to catch the car thief on tape at night, the battery powered motion activated security cameras with starlight night vision will be the most helpful tool to recognize the prowler's face.

7. Battery Life

The battery life of wire free battery operated motion activated security cameras is often listed in the product specification. You can make a comparison among some battery operated security cameras with motion detectors and go for the one with longer battery life.

In fact, your actual usage can also impact the camera's battery life. Learn the tips on how to extend battery life of indoor & outdoor battery motion activated surveillance cameras.

Better Idea: The outdoor battery motion activated surveillance cameras that offer multiple powering options can free you from the concerns about battery life.

Taking Reolink Argus® 2 and Reolink Argus® Pro for example, both of them can get continuous power from both the included rechargeable battery and the Reolink solar panel, saving you the trouble and money to replace batteries frequently.

    • Ray Cruz

      I'm looking for a battery-powered motion detection camera that can sense the motion of water leaking through my roof in a completely dark attic. Are any Reolink cameras capable of this level of sensitivity?

      • Yolanda

        Hi Ray, as I have introduced in this post, the battery powered motion activated security cameras work by detecting the changes of temperature in the detecting areas, so they can't sense the motion of water leaking. And for the traditional plugged-in motion detection security cameras relying on calculating the video frame change to work, it is hard to say whether they are capable of this level of sensitivity. It basically depends on whether there are distinctive changes between consecutive frames.

        • Ray Cruz

          If I can turn it on remotely, will it be able to capture the leaking water in an otherwise dark room?

          • Yolanda

            Hi Ray, yes, all of Reolink security cameras can capture clear and sharp images in low-light conditions and even in total darkness. So you can remotely view the camera to see if there is any leaking water in the dark room anytime on your mobile devices.

    • Dov Avnon

      Yolanda -for a large project i am looking for battery-powered camera that will be able to send the motion alerts directly to our cloud server. Do you give API for integration . http://www.excelldirect.eu excell4security@gmail.com
