Turbo HD 2MP refers to a high-definition surveillance technology that delivers 2 megapixel video resolution, typically equating to a resolution of 1920x1080 pixels. This technology is often used in security cameras and DVR systems, enabling the capture of clear and detailed images in both day and night conditions. Turbo HD systems utilize coaxial cables to transmit video signals, allowing for longer distances compared to traditional IP cameras, while still providing high-quality footage. This makes it a popular choice for both commercial and residential security applications.
