What to Know About Motion Detection for CCTV Systems

Adding CCTV systems and cameras to your overall security system can be a great way to bolster your security, particularly at access points to your property. Motion detection technology has made these cameras even more useful for providing clear and reliable results.

But how exactly does motion detection technology work for CCTV systems in Phoenix? Here’s an overview of what you should know.

About the technology

Motion detection is a common feature on DVR recorders used in security systems. When in use, the DVR constantly monitors the images taken by the camera, and then determines if there is any movement. It accomplishes this by analyzing individual image frames in comparison to previous ones. Based on existing differences in those image frames, it can determine whether or not any motion took place at a particular time. So essentially, it is the DVR, rather than the cameras themselves, that’s searching for and detecting the movement in the area being surveilled.

There are some limits to this technology. DVR may occasionally have a difficult time differentiating between some slight movement in the background, changes in light or someone entering the property. This can result in some false triggers and alerts.

To lower the chances of these false alarms, you can limit where the DVR searches for movement to a smaller area of the screen, or to a certain number of areas; the DVR does not have to scan over the entire screen. In some cases, people will only set the DVR to record footage if motion is detected so they can extend storage time for footage; otherwise it might be automatically deleted before they’re ready to let it go. However, this generally isn’t recommended—motion triggering is better used as bookmarks within 24/7 recording to more easily identify important sections of film, and to prevent an issue where there was motion but the system missed it.

Some of the benefits of using a motion detection camera as part of your security system include:

• Based on when the motion detection system was triggered, you can determine the exact time of break-ins to assist police in their investigation.
• You can get immediate notification from your home security applications when the motion sensors are triggered.
• Because the motion detection technology creates bookmarks in your footage, it becomes easier to sort through your 24/7 footage to find areas of interest where something important occurred on camera.
• The technology is relatively affordable, making it a feasible entry point for people looking to add security cameras to their properties or their existing security systems.
• If set up to only record when they sense motion, they will save you a lot of money on utility bills over other varieties of security cameras.
• Remote monitoring functionality is included with motion video cameras so you can check in from a distance at any time.
