A complete CCTV system needs cameras (IP or analog), a recording device (NVR/DVR), storage (HDD/Cloud), power supply, cabling or network setup, a display monitor, and software for management. Optional features include motion detection, remote access, analytics, and backup power (UPS). Proper placement ensures full coverage.

Cameras can be wired or wireless. Wired cameras use cables for power and video transmission, offering stable connections but needing extensive cabling. Wireless cameras transmit data via Wi-Fi, making installation easier but relying on a strong network and regular power, often with battery backup for flexibility.

To choose the right camera, consider the area size—wide-angle cameras work well for small spaces, while PTZ cameras are ideal for covering large areas. Opt for higher resolution (e.g., 1080p or 4K) for detailed images. For low-light or nighttime surveillance, select infrared or low-light cameras. Dome cameras are better suited for indoor use, while bullet cameras are ideal for outdoor environments. Lastly, decide between wired or wireless based on installation ease and connectivity requirements.

Yes, you can connect a CCTV camera to your computer. Most IP cameras support direct connections via network cables or Wi-Fi, while analog cameras require a DVR. Use camera-specific software or web interfaces to view and manage footage. Ensure your computer meets system requirements and has adequate storage if recording locally.
