Camera ElectoTech (Indoor – Outdoor)
- Closed-Circuit System:
- Unlike network cameras (IP cameras), CCTV cameras operate within a closed circuit.
- They are directly connected to a DVR (Digital Video Recorder) or a monitor via coaxial cables or other wiring.
- The video signals remain within the local system and are not transmitted over a network.
- Components:
- CCTV Cameras: These cameras capture video footage.
- DVR: The DVR records and stores the video from the cameras.
- Monitor: Used for live viewing or playback.
- Cabling: Coaxial cables or other wiring connect the cameras to the DVR.
- Analog vs. IP:
- Analog CCTV Cameras: These are traditional cameras that transmit analog video signals.
- IP Cameras: These are network cameras that use digital technology and transmit video over an IP network (such as Ethernet or Wi-Fi).
- Resolution :
- Analog CCTV cameras typically have lower resolution compared to IP cameras.
- Common analog resolutions include 720p (HD) and 1080p (Full HD).
- Night Vision:
- Many CCTV cameras come with built-in IR LEDs for night vision.
- These LEDs allow the camera to capture video in low-light conditions.
- Recording and Storage:
- The DVR records video from the cameras onto a hard drive.
- Storage capacity depends on the DVR and the hard drive size.
- Older systems may use VHS tapes for recording.
- Local Monitoring Camera ElectoTech (Indoor – Outdoor):
- CCTV systems are often used for local monitoring within a specific area (e.g., a store, office, or home).
- They are commonly seen in retail stores, banks, parking lots, and public spaces.
