Maybe you’ve always been interested in how CCTV works or you’re probably looking to purchase a security system for your home or place of business. There are a couple of terms that you should be familiar with, even if you don’t know all there is to know about CCTVs. Today, we bring to you five CCTV-related terms that you should know.
Motion detection is the analytical process of detecting movement or a change in the environment relative to an object or a change in the position of an object relative to its environment. Devices equipped with motion detection capabilities have sensors that detect a disturbance in the infrared spectrum, after which an image can be captured or an alarm can be activated. It allows you to tag parts of the video to identify changes in the scene that motion was detected. Motion detection is typically used to detect unauthorized entry.
Intelligent Video Surveillance (IVS)
In addition to what motion detection offers, an IVS system allows you to track a moving target, it has license plate recognition, visual detection of suspicious activity, automatic audio, night vision initiated by motion sensors, high definition picture quality, and the ability to count those entering and leaving.
This is a well-known term out of all the CCTV-related terms. Remote Viewing refers to the ability to see the images and videos that your CCTV cameras pick up from an external remote location that is not close to where your security cameras are. With the aid of the internet, users can view live video streams or playback footage of their security cameras on a smartphone, PC, or laptop from anywhere globally, and this is a very common feature of most CCTV systems.
Mainstream refers to one of the viewing streams that your recorder can apply to the incoming video data from your cameras and it is supposed to be the highest quality encoding of your (on-site) cameras. When recording to the hard disk, it’s the mainstream that is written to the disk by your NVR or DVR. In your mainstream settings, you’ll find that you can select the recording resolution that you prefer, as long as it is within the specifications of your cameras.
The transmission of data from your recorder or over the Internet consumes bandwidth when viewing remotely, and from the recorder’s local display, live viewing requires encoding/decoding. The amount of bandwidth used depends on the resolution and bitrate of the camera, so you should have your sub stream enabled and set to a reduced bitrate and resolution. By doing this, less data or bandwidth is used up. Substream basically allows you to reduce streaming quality for remote or live viewing.
