6. **Analog Camera**
- **Description**: Traditional CCTV cameras that transmit video signals over coaxial cables. They are generally used with analog DVRs (Digital Video Recorders) and are often more cost-effective compared to IP cameras.
7. **Wireless Camera**
- **Description**: Wireless cameras transmit video signals via Wi-Fi or other wireless technologies. They offer flexible installation options but may be affected by signal interference.
8. **Network Camera**
- **Description**: Also known as IP cameras, these cameras connect to a network for video streaming and recording. They offer high-definition video and advanced features like motion detection and remote access.
9. **Infrared Camera**
- **Description**: Equipped with infrared LEDs, these cameras can capture video in complete darkness by using infrared light. They are commonly used for night surveillance.
10. **360-Degree Camera**
- **Description**: These cameras provide a full panoramic view of the area. They are ideal for surveillance in large spaces, such as parking lots and shopping centers.

21. **Motion Detector**
- **Description**: Sensors that trigger recording or alerts when motion is detected within the camera’s field of view. They help in efficient monitoring and reduce unnecessary recording.
22. **Alarm System Integration**
- **Description**: Integrates CCTV systems with alarm systems to enhance security. It can trigger alerts and recording based on alarm conditions or events.
23. **CCTV Cable Tester**
- **Description**: Used to test and troubleshoot CCTV cables, ensuring proper signal transmission and identifying any faults in the wiring.
24. **Surge Protector**
- **Description**: Protects CCTV equipment from power surges and spikes, helping to prevent damage to cameras and recording devices.
25. **UPS (Uninterruptible Power Supply)**
- **Description**: Provides backup power to CCTV systems during power outages. It ensures continuous operation of cameras and recording devices.
26. **Wireless Transmitter/Receiver**
- **Description**: Allows for wireless transmission of video signals between cameras and recording devices, suitable for installations where cabling is impractical.
27. **Camera Lens**
- **Description**: Lenses can be interchangeable or built-in, affecting the field of view and zoom capabilities of CCTV cameras. Different lenses are used based on the specific surveillance needs.
28. **CCTV Enclosure**
- **Description**: Enclosures protect cameras from harsh environmental conditions, such as extreme temperatures and physical damage, ensuring reliable operation.
