Sony sử dụng công nghệ nén video mới nhất, cung cấp hình ảnh chất lượng cao nhất với bit-rate chỉ bằng phân nửa so với yêu cầu ở thiết bị thường. Điều này làm giảm tắc nghẽn băng thông và chi phí sử dụng, mang lại lợi ích cho điểm có băng thông hạn chế hoặc trong tình trạng mạng không ổn định.

Thông số kỹ thuật:

- Bộ thiết bị HNTH PCS-XG77 bao gồm:

- Đầu Codec x 1, Camera chất lượng FullHD x 1

- Micro đa hướng x 1, Remote điều khiển x 1

- Độ phân giải: 720p

- Truyền dữ liệu trình chiếu: Đã kích hoạt sẵn

- Kết nối đa điểm.

- Hỗ trợ lưu trữ qua USB lên đến 128 GB
