Motion detection is an extremely powerful tool when it comes to any CCTV setup. There are many benefits to using motion detection over standard or constant recordings:
- The ability to bring a camera into view when motion is detected
Great for businesses that continuously monitor their CCTV or to be alerted to anyone trying to gain access to a building / site
- Conserving hard drive space, due to less footage being recorded
A camera focused on a typically inactive point (such as a fire door or garage) would only produce a few minutes of footage per day, as opposed to a full 24 hours
- Triggering email notifications or audible alarms
Extremely useful for overnight monitoring or warning you when someone has entered an area typically off-limits
- Creating individual events on the hard drive
Making it easier to locate footage for playback or exporting purposes
Before we go into tricks and tips on how to get the most out of motion detection, it’s worth noting how the technology works to help you make better decisions when configuring your equipment.
Cameras contain an image sensor, which is fed light via the lens, and each pixel of the image sensor records how much light it is detecting. The combination of light and dark areas of each pixel create the images that result in the video being produced.
Motion detection systems will compare sequential images to determine if motion has occured – if a certain quantity of pixels detect a change in light conditions then motion will be reported, and that quantity of pixels can be defined by the adjusting the sensitivity level.
The sensitivity considers the change in light and dark levels of each pixel, from image to image. A high sensitivity setting will require few changes to trigger motion recording and a low sensitivity setting will require a large number of changes – such as the lights being turned on in a dark room.
Finding the right balance with your motion detection settings can be a time-consuming experience, particularly if you have several cameras and varying light conditions. Here are a few things you may need to factor in during configuration:
- Is there a road in the image?
You may reconsider the camera placement or simply set up masking to ignore the road
- Are there likely to be animals in the image?
You will need to reduce the sensitivity level to stop them from triggering motion recording
- Are there trees in the image?
Under windy conditions, branch movements will trigger motion recording constantly if the sensitivity is too high
- Are there reflective light sources in the image?
Remember, sudden bright lights may be detected as motion if prominent enough
While there is no one-fits-all solution, by remembering how lighting impacts on motion-detection systems you should be able to configure the system to achieve exactly what you need it to. Having someone walk through, or replicating typical actions in, the focus area will greatly enhance the speed and accuracy with which configuration takes place.
If you decide you need to compromise on the sensitivity setting, always go for the higher option – while you may not want the increased number of alerts, it will be worthwhile when you capture crucial footage that would have been ignored otherwise.
