What Is a Surveillance Camera?
Surveillance cameras serve as electronic eyes, providing continuous monitoring in locations where constant human supervision is impractical. These cameras capture video footage for security and monitoring purposes, often utilizing digital storage to record events over time.
Applications of Surveillance Cameras
Surveillance cameras are essential across various settings, from retail stores and museums to power plants and control rooms in process factories. Their primary function is to enhance security, monitor operations, and ensure safety in both public and private spaces.
Principle of Surveillance Cameras
Modern surveillance systems comprise three main components: the camera itself, transmission wiring for signal relay, and a recording device for data storage. Transitioning from analog film to digital data storage has significantly improved efficiency, allowing for broader application and easier management of recorded footage.
How to Choose a Surveillance Camera
- Monitoring Range and Viewing Angle: Select based on the surveillance area, opting for wide-angle or zoom-capable cameras as needed.
- Resolution: Choose a resolution that meets your detail requirements, from 720p HD to 4K Ultra HD, depending on the need for clarity.
- Day/Night Capability: For 24/7 monitoring, ensure the camera performs well under varying lighting conditions, considering IR cameras for low-light environments.
- Security Features: Advanced features like motion detection and facial recognition enhance monitoring effectiveness and crime prevention.
- Reliability and Durability: Durability is critical for long-term operation, so look for cameras with environmental resistance and a solid warranty.
- Compatibility and Extensibility: Ensure the camera integrates well with existing systems and offers the flexibility to expand your surveillance network.
