Video surveillance systems
CCTV (Closed-Circuit Television) systems are video recording systems used to provide security and monitoring at facilities, public places or special areas. These systems are used for various purposes such as security, crime prevention and data collection by recording or monitoring events in real time. Below is detailed information about the main components and features of CCTV systems:
Main components of CCTV systems:
Cameras:
IP cameras: These are cameras that work over the Internet and transmit images digitally. It provides quality images and allows remote control.
Analog cameras: These are cameras based on older technology and transmit images over coaxial cables. It may have a lower resolution than IP cameras.
PTZ cameras: These cameras can move (pan, tilt, zoom) and monitor a large area. They can focus on specific areas remotely.
Night Vision Cameras (IR Cameras): Equipped with infrared lights that can record images at night and in low-light conditions.
Image Compression Technologies:
H.264 and H.265: These technologies help reduce the size of video files, allowing you to store video longer using less memory. H.265 provides more efficient compression.
Recorders:
DVR (Digital Video Recorder): Used for analog cameras and stores video in digital form.
NVR (Network Video Recorder): Designed for IP cameras. Collects and stores video in digital format over the network.
Cloud Recording: Storing video on remote servers using cloud technology. This method does not require additional physical storage devices.
Monitors: Screens used to view images from CCTV cameras. It is used to view live footage or review past videos.
Network Equipment: CCTV systems require devices such as routers and switches to connect to the network. This is especially important for IP cameras and remote monitoring.
Storage devices: Hard drives, SSDs or cloud storage systems are used to store videos. The amount of storage varies depending on the number of cameras, the quality of the recording and the length of time the video is stored.
Features of CCTV systems:
Motion detection: With this feature, the camera automatically starts recording video or sounds an alarm when motion is detected. This helps save memory and record only important moments.
Real-time monitoring: CCTV systems provide real-time viewing. This allows security services to intervene immediately.
Mobile compatibility: Most modern systems are compatible with smartphones and tablets, allowing users to control remotely from anywhere.
Two-way audio. Some cameras support two-way audio. This means you can listen to the audio and send voice messages in the same location where the camera is located.
Scheduled recording: Some CCTV systems can be programmed to record during a certain period of time (for example, only during working hours).
Alarms and Notifications: Notifies the user when motion, sound or other abnormal activity is detected. These notifications can be delivered via email or mobile apps.
Sites of Use:
Commercial Facilities and Enterprises: To prevent theft, vandalism and other illegal activities.
Home Security: Monitoring the home environment, being aware of potential threats.
Public Places: To ensure safety and order in parks, streets, transport hubs and other crowded places.
Educational Institutions: To ensure safety in schools and universities.
CCTV systems play an important role in ensuring safety and control in the modern world. The protection of the territory is ensured by selecting cameras and systems that suit the specific needs of each location.
