黎巴嫩采购需求：监控系统制造商，闭路电视摄像机系统，IP摄像机系统，Ptz闭路电视摄像机，NVR套件，IP AI摄像机

I'm looking to purchase a comprehensive NVR solution that can support up to 64 cameras. It's crucial that the NVR can handle high-quality video feeds and provide reliable storage capabilities. Additionally, I need a hard disk that has sufficient capacity to store all the footage from these cameras without compromising on performance. Please provide me with details on the available options, including specifications and pricing for both the NVR and the hard disk. I'm also interested in any recommendations you might have based on similar setups. If you could include information on warranties, support services, and any bulk purchase discounts, that would be greatly appreciated. Looking forward to your prompt response!
