Modern home security systems include motion sensors as standard equipment. Wondering do motion sensors have cameras?

Usually, motion sensors don’t have cameras. While many believe that these devices’ cameras are essential for capturing motion, sensors work in a completely different way.

Do Motion Sensors Have a Camera?

Motion sensors can have a camera and record if the sensor is tripped. However, these cameras only record when the sensor detects a change in motion or something is detected. The DVR/NVR will not receive any recordings otherwise.

Many motion sensor models can also be integrated with outside camera systems. In this manner, if a motion is detected, you can use an existing camera to start and stop recording. This not only saves you space on your hard drive but also eliminates the need to skip through hours of the recording to find any suspicious activity.

Additionally, motion sensors with a camera can help troubleshoot installation problems.

If you’ve installed or plan on installing a motion sensor for the first time, it can be frustrating. It is necessary to adjust the sensor’s sensitivity, potential triggers, and behavior. The sensor is prepared to detect the proper signals once you’ve completed all three.

Luckily, it would be much simpler to determine what set off the alarm if the motion sensor’s camera functioned. The NVR/DVR would receive the sensor camera’s recording just like it would any other regular security camera system. Ask your storage provider if the model supports cloud-based storage.

How Do Motion Sensor Cameras Work?

Motion sensor cameras, depending on the type of the sensor, pick up signals from objects in proximity and raise alarms. If there is significant motion or a change in motion close to a microwave or infrared sensor, the camera will only switch to recording.

Pictures (or frames) are simply scrolled at a set speed in video recordings. One step further, the sensor selects a frame from the video and then performs a second search to determine whether there has been any change between the two frames. Movement is significantly reduced if both are the same. The sensor would switch the camera to start recording and start detecting movements if the two kept changing.

Users of motion detector cameras can adjust the sensitivity. Suppose that at the moment, your sensitivity is set to 80%.

In this manner, change that totals 80% or more is likely to cause the motion sensor camera to start recording. This is, however, fairly sensitive and prone to picking up signals from things other than people.

You’d have to test the sensor camera‘s sensitivity and see what works for you. The camera may not trigger as much if it is mounted in a remote area. If not, you should change it to a moderate sensitivity recorder so that it will at least only record human sounds.

How to Tell If a Motion Sensor Has a Camera?

It’s likely that the motion detector you already own lacks a camera. This is due to how much more expensive the device would be. Additionally, you would be able to access the camera and be alerted if the sensor were to be triggered.

If you’re unsure whether a motion sensor has a camera, see if an external camera is fastened to it.

If you shine a flashlight at the motion sensor as an alternative, it will blink a red or green light, signifying a camera lens.

Conclusion: Do Motion Sensors Have Cameras

Folks, motion sensors are great on their own. Your best bet for surveillance, however, would be to pair them with a security camera or choose a modern model.

One device is more cost-effective, increases the security of your home, and requires less maintenance than two separate devices.

Choose a model without a camera if you don’t like motion sensors that can record or have cameras. Detections based on alarms are still very effective.
