Wireless Motion Activated Security Camera


The best alternative to the conventional security camera is the motion triggered security camera. Unlike normal security cameras, motion activated cameras do not save the video images 24 hours in secondary devices. This turns out to be an advantage where you can save disk storage up to 90 percent when compared to normal security cameras.

The most common approach that we use today to save the video captured is to use hard disks. However you can imagine how much disk space will be needed to store the video data recorded every minute for 24 hours!!

The main theory behind the motion activated security camera is that, the video is only captured and stored if a motion is detected. This thus saves a huge amount of hard disk space and is especially when the video captured is of very high quality and good resolution which effectively increases the amount of data. Moreover, when you save a lot amount of disk space, you can save your video data for a longer amount of time. You need not much worry about hard disk space running low or spending huge cash on hard disks!

Motion detection cameras are a blessing especially where motion can be inferred as a danger or a sign of intrusion. For example some area which are monitored at night (warehouses), your home or office buildings.

Further, some motion activated security cameras come with motion tracking. These cameras has built in mechanism composed of stepper motors, tilting and panning capabilities and fixed software which makes the camera to follow the target movements. These cameras therefore require certain amount of computing by the software, most motion activated cameras are IP cameras which are strong enough to handle their job.

How are the cameras triggered?

There are two methods in which this is achieved. First an optical sensor is used (very much similar like the ones used in day-to-day security systems) to activate the camera and start recording the image frames. Second the IP camera software will compare the recorded frame (a constant comparison is carried out) based on the input provided. The video is saved if the captured frames are different (a captured frame will only be different if there is some movement). There will be no recording if the two consecutive frames are same (i.e. there is no movement at all).

Thus we can see that motion activated cameras are quite useful when want them for a long run.
