Guangdong Macro-Video Smart Technologies Limited provides a professional guide to selecting the right CCTV camera. First, determine the application scenario: commercial venues may require high-definition HD-TVI/CVI cameras, while homes can use standard-definition models. Consider resolution: 720p to 1080p is suitable for most needs, with 4K for detailed monitoring. For outdoor use, prioritize IP65+ weatherproof housing and infrared night vision up to 30 meters. Indoor cameras can focus on compact designs. Transmission method matters: coaxial cables for short distances, or HD over coax for extended runs. Ensure compatibility with your DVR, and consider bundled CCTV camera kits that include DVRs, cables, and power adapters for convenience.
