The project involved upgrading an existing security system where the client’s old setup used coaxial cable cameras. Due to site constraints, re-cabling would have been extremely challenging. To address this, we recommended the Dahua HDCVI system, which allowed us to utilize the existing coaxial wiring. We upgraded several cameras and replaced the recorder, enabling a seamless transition to higher-quality surveillance. The upgraded system now provides improved video clarity, although some differences in camera quality can be observed due to the mix of old（cam2/9/11/12） and new equipment.
