CCTV cameras serve not only as a deterrent against petty criminals and intruders but also offer the capability to monitor your home remotely. Recorded video feeds enable you to review activities around your home or business daily or weekly, while smart analytics can activate an alarm and warning siren upon detecting suspicious activity. In cases of crime or accidents, CCTV cameras provide recorded evidence that can support criminal investigations or insurance claims.

Sure, here's the paragraph rewritten in Australian English:

The number of megapixels required depends on where the camera is placed and its intended use. Lower-resolution cameras are typically more effective for capturing images in low-light conditions. Image quality determines how sharp and clear video signals are, as well as the ability to zoom into recorded footage later. Several factors affect the image quality of a CCTV system:

• Camera Capture Quality: Measured in megapixels (MP).
• NVR Recording and Output: Measured in both MP and digital video formats (e.g., 1080P HD and 4K UHD).

For instance, our Dahua 6MP IP CCTV package includes 6MP cameras and a 4K UHD NVR capable of capturing and outputting resolutions up to 8MP, ensuring your system remains up-to-date and future-proofed.

The night vision capabilities you need will depend on the available light in your area, your budget, and specific requirements. When selecting a CCTV camera, remember that night vision performance is influenced by the camera's resolution. Higher-resolution cameras (8MP or 6MP) typically have poorer night vision capabilities compared to lower-resolution cameras (e.g., 4MP).
