This means you can quickly respond to any suspicious activity, whether you're at home or away.

Not only do they offer improved security, but they also save energy and storage space by recording only when motion is detected. Easy to install and available in many different styles and features, motion activated security cameras are key to modern security systems, giving you peace of mind and helping to protect what matters most.



Understanding Motion Activated Security Cameras:


Motion activated security cameras are an essential part of modern home and business security systems. These cameras are equipped with sensors that detect movement within a certain range. When motion is detected, the camera starts recording video and sends an alert to your smartphone or other devices. This allows you to quickly respond to possible security threats, whether you're at home, at work, or on the go.

There are two main types of motion detection tools used in these cameras: Passive Infrared (PIR) sensors and image comparison. PIR sensors detect body heat, which triggers the camera when a warm object, like a person or animal, moves within its range. Image comparison works by looking at video frames one after another to spot any movement.

One of the key benefits of motion activated security cameras is how well they work. They only record when movement is detected, saving storage space and making it easier to review footage. These cameras can combine with other smart home devices, improving overall security and convenience. Features like night vision, two-way audio, and high-definition video quality increase their effectiveness.

Overall, motion activated security cameras provide a reliable and proactive way to monitor and protect your property, giving you peace of mind and a higher level of security.

What is the difference between a motion sensor and a security camera?


Motion Sensor:

  • The primary function of a motion sensor is to detect movement within a specific area. When motion is detected, it triggers an alert or activates another device, such as lights or alarms.

  • Motion sensors typically use technologies like Passive Infrared (PIR), microwave, ultrasonic, or a combination of these to detect movement. PIR sensors detect changes in infrared radiation (heat), while microwave sensors use electromagnetic waves.

  • They are often used in security systems to trigger alarms, turn on lights, or activate security cameras. They can also be used in home automation systems to control lighting and other devices.

  • Motion sensors do not provide visual information. They cannot record or capture video footage; they only detect and respond to motion.


Security Camera:

  • Security cameras are designed to capture and record video footage of a specific area. They provide visual surveillance and can be monitored in real-time or reviewed later.

  • Security cameras come with various features such as high-definition (HD) resolution, night vision, two-way audio, and motion detection. Some cameras are equipped with AI capabilities to differentiate between humans, animals, and other objects.

  • They are used for continuous monitoring and recording, providing visual evidence that can be used for security, monitoring, and reviewing events. They can be part of a larger security system and integrated with motion sensors for enhanced functionality.

  • Unlike motion sensors, security cameras can provide visual and audio evidence. They can record events, provide live feeds, and store footage locally or in the cloud.



  • Many modern security cameras come with built-in motion sensors. When motion is detected, the camera starts recording or sends alerts, combining the functions of both a motion sensor and a camera. This integration allows for more efficient monitoring and storage, as the camera only records when motion is detected.

In summary, motion sensors detect movement and trigger responses but do not capture visual information. Security cameras capture and record video footage, providing visual surveillance. Many advanced security systems integrate both technologies for comprehensive security coverage​.



Are motion sensor cameras always recording?

Security cameras can be set up to record continuously or only when motion is detected. The continuous recording will capture all activity in the camera's field of view, regardless of whether there is movement or not.



Do motion cameras need Wi-Fi?


Yes, it is possible to use your security cameras without internet. It's a good option if you have poor service or lack high-speed access. Many of the cameras that don't use the internet connect through a closed system, such as a CCTV or mobile setup.
