CÁCH TÍNH DUNG LƯỢNG Ổ CỨNG VÀ THỜI GIAN LƯU TRỮ CAMERA HIKVISION

Đăng bởi admin 15/12/2019 53 Bình luận Hướng Dẫn,

Bạn đang tìm cách tính thời gian lưu trữ camera, hệ thống camera lưu được mấy ngày, Camera Hikvision lưu được bao nhiêu ngày hay Camera Dahua lưu được bao nhiêu ngày? Bài viết dưới đây chúng tôi sẽ hướng dẫn bạn. 

cách tính thời gian lưu camera hikvision

HƯỚNG DẪN SỬ DỤNG TOOL HIKVISION DISK CALCULATOR 

Để đơn giản. Chúng ta hãy làm một ví dụ cụ thể. Cần tính thời gian lưu trữ của Trọn Bộ 4 Camera Hikvision 2.0Mp 1080P. Bạn khởi động phần mềm Storage And Network Calculator 

cách tính dung lượng ổ cứng camera hikvision

#Giải thích việc chọn các tham số

  1. Chọn chuẩn hiển thị hình ảnh: PAL (Chọn NTSC đối với các sản phẩm phân phối tại bắc mỹ và canada)
  2. Chọn số lượng camera là: 4 Camera vì chúng ta có 4 camera trong hệ thống
  3. Chuẩn nén: Chọn H.265+ (Vì đầu ghi DS-7104HQHI-K1 hỗ trợ chuẩn nén H.265+, mặc định chuẩn nén của đầu ghi là H.265, Để đạt hiệu quả quan sát tốt nhất chúng ta cần Enable H.265+ trên cả 4 channel trong đầu ghi)
  4. Độ phân giải: Chọn 1080P (1920x1080) là độ phân giải ghi hình mà đầu ghi hỗ trợ
  5. Tốc độ khung: Chọn 15fps (Vì mặc dù camera ghi hình đạt 1920x1080 pixel ở 25fps. Nhưng đầu ghi chỉ hỗ trợ ghi hình ở 15fps@(1920x1080) vui lòng đọc thêm datasheet thiết bị để có thêm thông tin. 
  6. Bitrate mặc định: Tham số này sẽ tự động hiển thị khi chọn xong 5 tham số ban đầu. Đây là tham số khuyến cáo của hãng để đảm bảo hình ảnh chất lượng không bị suy giảm khi nén. (Bạn không nên thay đổi tham số này). Mặc định ở đây bitrate sẽ là 832Kbps. 

CHỌN ADD ĐỂ BẮT ĐẦU TÍNH TOÁN

tính toán thời gian lưu camera hikvision

Như vậy. Bộ 4 Camera Hikvision 2.0Mp Gắn đầu ghi DS-7104HQHI-K1 hỗ trợ chuẩn nén H.265+ với ổ cứng 500GB sẽ lưu được dữ liệu trong vòng 13 Ngày. 

Tương tự. Với hệ thống camera IP hoặc các dòng đầu ghi khác của Hikvision. Bạn có thể dễ dàng tính toàn thời gian lưu trữ của hệ thống camera cũng như xác định được dung lượng ổ cứng cần trang bị cho hệ thống camera của mình 

 

VÌ SAO BẠN CẦN BIẾT CÁCH TÍNH THỜI GIAN LƯU TRỮ CỦA HỆ THỐNG CAMERA

Như các bạn biết rằng, Camera ngoài chức năng xem trực tiếp camera trên các thiết bị như điện thoại, laptop, tivi… Còn hỗ trợ xem lại những hình ảnh được lưu lại ở 1 ngày trước, tháng trước thậm chí 1 năm trước. Các bạn không có thời gian xem trực tiếp camera mọi lúc mọi nơi, nhưng khi có sự cố bạn có thể trích xuất dữ liệu của camera trong quá khứ. Có khi nào bạn tự hỏi rằng, hệ thống camera của mình sẽ lưu trữ được bao nhiêu ngày ? Rõ ràng, đây là việc rất quan trọng khi lắp đặt camera nhưng khá nhiều khách hàng thường ít quan tâm tới vấn đề này mà phó mặc cho đơn vị lắp đặt chọn dung lượng ổ cứng chỉ quan tâm đến số lượng camera và giá của bộ camera bao nhiêu càng rẻ càng tốt. Hậu quả là. 

Khi có sự cố xảy ra, cần xem lại camera thì phát hiện ra dung lượng ổ cứng quá ít, camera chỉ ghi hình được 1-2 ngày. Dữ liệu camera đã bị ghi đè mất và không lấy lại được, không xem lại được, không trích xuất lại được. Lắp camera mà khi có sự cố lại không xem lại được

Do đó, Chúng tôi thành thật khuyên bạn. Khi quyết định lắp đặt camera phải tìm hiểu xem đơn vị lắp đặt camera đang chào ổ cứng loại gì, dung lượng bao nhiêu và thời gian lưu trữ là bao lâu. Để tránh các trường hợp đáng tiếc xảy ra sau này.
