The 5 Best Motion Sensor Cameras (And What You Need to Know About Them)

Sifting through hours of footage to find the suspect who stole a parcel from the doorstep isn’t practical or enjoyable. Hence, one of the most important features of modern security cameras is motion detection. 

Cameras with motion sensors capture footage only when sufficient movement occurs, while AI-based features like person detection can eliminate unnecessary footage altogether.

Discover our top 5 motion activated security cameras below, and find out more about how they work and how they can be used.

Read our in-depth overview of AlfredCam that details everything you need to know about AlfredCam, the first indoor security camera from AlfredCamera.

What Can Motion Sensor Cameras Do?

Motion activated cameras detect movement through a motion sensor, starting to record only when sufficient movement is detected. This makes them perfect for use in a security context, since they are able to notify users of unusual movement and record short clips rather than record continuously.

PIR, or ‘passive infrared’, is used by most motion activated security cameras. It detects infrared energy given off by objects, be it human or animal. If there’s a rapid shift in infrared energy detected as the object crosses the field of view, the smart camera will start recording.

Prefer the idea of recording continuously rather than just relying on motion detection? Find out how to use continuous recording with AlfredCamera.

Can You Turn Your Phone Into a Motion Sensor Camera?

AlfredCamera makes it possible to turn phones into motion sensor cameras.  

Launched in 2014, Founder and CEO Alex Song developed the app to address a major shortfall in the market—ultra-affordable security cameras that boast the features of some of the most expensive available, including motion detection.

Alfred can be used on old phones, tablets, computers, or alongside AlfredCam, a dedicated indoor security camera with infrared night vision. When a viewing device detects motion, the user’s phone will be instantly notified. 

Premium users also have access to person detection, which uses AI to trigger motion recording only when a human is detected, thereby reducing unwanted notifications.

Still not sure if motion detection is for you? With AlfredCamera, you don’t need to spend a dime to find out. Grab an old phone, download the app for free, and try it yourself.

Advanced Motion Detection Features

Some motion detection cameras, including AlfredCamera, do more than just start and stop recording based on movement. Advanced features can make it a lot more useful to users in the long-run. 

Here’s the advanced features to look out for.

Person detection – the most important motion detection feature is person detection. Using software based AI, the security camera is able to recognize  motion caused by humans and ignore motion caused by nature, animals, or other objects. This can make it much more useful for everyday security, significantly reducing unwanted notifications caused by strong wind or animals.

Motion detection notifications from Wyze and AlfredCamera.

Facial recognition – less common than regular person detection is the incorporation of AI that learns, memorizes, and distinguishes faces. Some might find this a little dystopian, but it is a great way to be instantly notified of who is standing at the front door.

Nest’s ‘Familiar Face’ setting (available only with an Aware subscription) learns and eventually distinguishes faces that the user knows from one’s they don’t.

Motion detection zones – cameras facing the driveway might also pick up some of the street beyond the property. In such cases, establishing a motion detection zone is useful in eliminating unwanted notifications caused by people walking down the street. Some devices, including AlfredCamera, allow users to establish the specific areas of the frame that they want motion detection to apply to, thereby reducing pointless triggers.

Motion detection schedules – motion sensing cameras can be made even more useful through scheduling. Schedules automatically arm and disarm motion detection on specified days and times. If leaving for work in the morning, motion detection can be enabled for cameras viewing the doorway while the house is absent, for example. Likewise, some periods of the day may see extensive traffic, in which case continuous recording is preferable to avoid excessive notifications.

Do motion sensor cameras record all the time?

No, cameras with motion detection do not record all the time. They will only start recording when sufficient motion is detected. This motion also needs to occur within the assigned motion detection zone if one has been created, which AlfredCamera makes possible. Likewise, schedules and person detection will also affect how often it triggers.

Do motion cameras need WiFi?

Usually, motion detection cameras require a Wi-Fi connection to send push notifications to phones, meaning the true benefits of motion detection are derived from a camera connected to a stable internet connection. This doesn’t have to be the case, though. They can simply save footage to storage without sending a notification.

What is a PIR sensor?

A PIR sensor (passive infrared sensor) detects infrared energy given off in the scene it observes. Everything that emits heat also emits infrared energy, but infrared is invisible to the human eye. The PIR observes the shifting wavelengths. This information can then be processed to reveal information about movement, depth, size, and heat.

How far can security cameras detect motion?

Generally, security cameras detect motion somewhere in the vicinity of 15 to 25 feet. AlfredCam is able to detect motion up to 32 feet in daylight, and up to 22 feet in night vision mode.

What do motion sensors see?

In the context of cameras, motion sensors see infrared. A PIR (passive infrared sensor) is the type of sensor that detects general movement, but an imaging sensor is needed as well in order to gauge information about who, or what, moved, and these sensors are in all cameras. This compares sequential images from the footage, frame by frame, to determine information based on changes to the pixels.

How far can security cameras detect motion?

Generally, security cameras detect motion somewhere in the vicinity of 15 to 25 feet. AlfredCam is able to detect motion up to 32 feet in daylight, and up to 22 feet in night vision mode.

Why is motion detection not working?

Issues with motion detection could be down to a number of different things, including incorrect settings/setup, lights or other obstructions confusing the sensor, or even a damaged circuit board.For more on troubleshooting motion detection, check out our dedicated guide and FAQ on motion detection issues. For a more general guide, learn how to tell if a security camera is on and recording.

Can a mouse trigger a motion sensor?

A mouse is unlikely to trigger a security camera motion sensor, but in theory, it could. The factory settings of most commercial security cameras with motion sensors would purposely have the sensor ignore something so small. It would trigger it if it came very close to the lens.


Improving safety and security isn’t just a matter of installing any old camera. The tech we choose must be truly useful to us, and that requires convenience. With that in mind, motion detection is a vital feature many users will need to get the most out of a security setup.

Motion detection means efficient surveillance, streamlining and significantly improving the security of a space.

Motion detection in video surveillance systems: how it works and what features it has

“Hello! Let’s play?” – a chilling voice was heard in complete darkness and an empty closet. The doll with round eyes woke up from the movement and smiled predatoryly. The man screamed in fear and ran away. No one else stole anything at this plant.

It is possible to scare an intruder who has made his way to the territory of the object. But it is much more effective to react in a timely manner and prevent an offense. If improvised means can be used in private houses, then such methods will not work when protecting industrial enterprises, municipal and housing complexes. Spending large sums on round-the-clock video surveillance is not always wise. Is there a solution? Yes. Today we will tell you everything about motion detection and its benefits.


Features of cameras with a built-in sensor

The principle of operation of such devices is simple – a highly sensitive detector activates recording if a previously recorded image has changed in its field of view. For example, there was a movement of the vehicle or someone passed. In this case, the camera is in sleep (offline) mode all the time. It is turned on, but consumes energy resources at a minimum level. You can find out all the features of video surveillance in our article.

Which cameras have motion sensors?

All modern cameras have built-in motion sensors. This is one of the most important conditions for the production of such equipment. For the first time they were installed in analog cameras. However, before they did not have a recording function, which is why the introduction of a motion sensor was an extremely dubious undertaking. But in modern analog cameras, this problem is solved.

IP and AHD equipment may still not have a motion sensor in their device. Therefore, it is strongly recommended to separately pay attention to this nuance when buying. Otherwise, you will have to allocate additional hard disk space for storing recorded materials. However, such devices have a notification function via SMS if something happened at a given point.

How does motion detection work in video cameras?

If we analyze the issue more deeply, then there are two methods for detecting a moving target: hardware and software. In the second case, the camera constantly monitors the image as it is being formed on the matrix. Another way is possible – when detection occurs directly on the server that performs the processing. Then a computer with a special video card analyzes the image capture data and compares how much it has changed.

Hardware detection is carried out by a sensor and occurs using infrared rays from a detector built into the camera body. When an object is in the tracking zone, the rays are refracted. This is a signal to the device to start fixing the actions of an unidentified object. As soon as the situation levels off and the movement stops, the recording stops and the devices go into standby mode.

The choice of surveillance system in your company depends on the tasks, characteristics of the object and device. Detailed information can be requested from our employee at a free consultation. Write your question in the chat. We will contact you.

The breadth of choice makes it possible to choose components for a video surveillance system for almost any task. Adapt it to the location and specific wishes. We are ready to offer not only equipment, but also to mount cameras or mount a complex with detectors for the enterprise. We will select devices of any functionality:

  • a video camera with a sensor and saving to the card memory;
  • simple model plugged in and with battery;
  • analog equipment, motion detector + IP video camera;
  • outdoor device with modem and transmitter;
  • is a modern tracking device with remote control and broadcasting of signals via web resources.

External and built-in motion detector

In the past, the sensor was a remote infrared module. He reacted to the heat source and transmitted a signal to activate the shooting. Today, the detector works in the same way, but with one key difference – it is installed inside the chamber. Thanks to the achievements of modern microelectronics, this has become possible. Moreover, the installation of the sensor inside the device has significantly reduced the cost of production and the final price of video equipment.

What are the motion detector settings?

Each camera manufacturer provides its own set of adjustment functions. They may differ even from the same company, depending on the model. However, there are general settings for all cameras. These include:

  • zone setting;
  • size setting;
  • sensitivity setting.

Zone allows you to define the desired area on the image, which needs to activate the motion sensor. By adjusting the size, you can prevent the equipment from responding to glare, drops, rain, foliage, etc. Sensitivity is measured as a percentage, it affects the conditions under which the detector will turn on. If you set this indicator to a minimum, then the device will not respond to movement, and if you turn it on to the maximum, the sensor will begin to pick up the slightest changes in the picture.

Motion detection functionality in video surveillance systems

Video cameras with a detector are in most cases autonomous. They do not have additional power – they function due to the built-in high-capacity battery. Therefore, they are able to work for a long time without maintenance. The engineering solution is implemented in such a way that it is easy to move the camera to a convenient place or relocate the entire tracking system. But the advantages of cameras with a detector do not end there:

  • work in sleep mode, which means energy saving;
  • light weight;
  • mobility;
  • unpretentiousness in service;
  • is suitable for large objects.

Another key difference between fixed and wireless camcorders is how the image is broadcast and saved. The first option is rather outdated. The second requires an uninterrupted source of remote Internet connection. It will ensure a constant flow of information and its protection.

When installing a video surveillance system, pay special attention to the Wi-Fi adapter. The quality of transmission and image saving depends on its operation and stability of the connection. Remote access to cameras via the Internet connected to the network occurs by installing a special extension for a regular browser. No other software or pre-installed programs are required. It is enough to configure the camera software. An experienced specialist installs and adjusts the video surveillance system in a short time.

What can the camera do?

Hardware capabilities, as well as settings, vary by model and manufacturer. They are determined at the stage of automation and dispatching of engineering systems, with the help of which it is possible to control technological processes throughout the building. However, in addition to individual opportunities, there are mandatory ones. These include:

  • record activation;
  • save screenshots;
  • sending data to mail or phone;
  • connection to external devices (eg sirens).

Also, many cameras can work with preset settings. If necessary, in a certain period of time, the device will change its viewing angle. This feature is optional. However, it is found on almost all cameras.

Where are cameras equipped with a sensor used? With their help, video surveillance is carried out both within industrial zones and in private areas. For example:

  • Retail outlet or large chain stores – security and recording of events at night, as well as for monitoring the surrounding area and the work of personnel. Video cameras with different functionality are relevant in the cash register area, self-service halls and the entrance group.
  • Offices – placement of motion detectors at checkpoints and checkpoints, in meeting rooms and utility rooms. Events are recorded in accordance with the wishes of the customer. The inclusion of video image capture allows you to respond to emergency situations in a timely manner.
  • Installation in industrial and commercial enterprises of various types of ownership and type of activity to ensure the safety of the facility and property.
  • Municipal institutions, kindergartens, private and public schools – you can track all movements in real time and throughout the territory. In addition, motion detectors help ensure the safety of not only staff, but also visitors.
  • Entrance and entrance to the territory of cottage settlements and apartment buildings – motion detectors integrated into security and fire-fighting complexes will become a convenient tool for preserving property.
  • Parking lots, gas stations and individual stations, rest areas, repair shops, service stations — allows you to monitor entry and exit zones, and control compliance with the rules at the facility.

In addition, there are special micro-cameras with a motion sensor. They are used in monitoring what is happening in vast street areas. The model is imperceptible, so damage is unlikely, and the sensor will help weed out the whole hours of unnecessary footage that appears in any case when using a conventional device. A smart device guarding property and human life.

Quality control

Video surveillance cameras with motion sensors can significantly save hard drive space, increase archive depth and storage time, and reduce power consumption. As soon as a moving object enters the camera lens, the motion sensor is triggered and the picture recording starts. Some devices may have an image buffering function that allows you to save information that precedes the movement (for ten seconds). This increases the information content of the archive and makes it possible to understand the situation in more detail. Unlike analog video cameras, IP cameras with motion sensors are able to inform about the appearance of a moving object via SMS, email or local network. If you are at a distance, you can always connect to the camcorder via the Internet using a mobile application, for example, and control the situation. In addition, if the motion sensor is set to a specific area of ​​interest to you (a car in a parking lot, an entrance door, or something else), the video surveillance camera will only record when you move in this area, and not in the entire frame.

If, in addition to the motion sensor, the device is equipped with IR illumination, they are triggered simultaneously. That allows you to effectively use such cameras for night video surveillance.

There is a fine-tuning to exclude false alarms of the motion sensor. The user can set parameters such as an alarm response when moving objects that look like a human figure or have a certain size are detected.

If you decide to buy a video surveillance camera with a motion sensor, you should know their advantages and disadvantages.

The advantages are that the device allows you to record in high quality only when it is needed, thereby saving not only electricity (or an autonomous battery), but also hard disk space. Often these cameras have compact dimensions (less noticeable) and slots for memory cards (savings on buying a DVR).

Minus – if the setting is incorrect, frequent false positives can occur, which nullifies all the pluses. Therefore, a specialist in this field should set up a video surveillance camera with motion sensors.

Conclusion: These devices are great for indoor and outdoor monitoring with little traffic.
