Dahua Storage Calculator Download

A member is asking about using lower cost cameras with on-board storage. To that end, does anyone have experience using Dahua or Hikvision cameras with on-board storage? How easy / hard / complex is it to access recorded video, etc.?
I found it pretty easy, just put the micro SD card in, log directly into the camera, setup the storage just like it was a hard drive. To access recorded video, just go to playback and you can access it pretty easy, almost like you were using the NVR.
Agreed with others - we have used them as local recording whilst also sending a stream to Milestone (something we do with Axis but did not think the Hikvision would have the power) so far its worked well and the software is a "back the front" but it works. I have not tested it with proper VMS edge storage though, this is just isolated site connected via wireless, one stream goes to SD card locally (in case wireless goes down) and the other goes back to Milestone server a few kms away. My only suggestion is use good quality SD cards, saves a lot of problems later and improves playback performance.
We have used SD storage in certain situations with Dahua over the past three years and have found that the SD cards stop recording and are eventually not found on a high percentage of cameras. We can take the cards out reformat them and they will start working again. On one installation we had four cameras with two different models and in less than a year 3 failed. We have taken them out and tried them in a Mobotix camera and they will work fine. We only use class 10 Sandisk. We no longer offer the option for the Dahua product. If you still wish to go this route it is very easy to setup and access the video, just be prepared for failures.
Dual-stream can achieve two different bandwidth stream requirements for local and remote transmission. The mainstream can be used for local transmission to obtain clearer storage video. The substrate can be used for remote transmission to obtain smooth images and recordings due to bandwidth limitations.
In general, the mainstream is larger with higher definition and higher bandwidth. The substream reduces the image format under the image environment of the mainstream, and it has a lower resolution and smaller bandwidth than that of the mainstream. In general, the mainstream is used for storage and the substream is used for network transmission. The mainstream is stored locally while the sub-stream is suitable for image transmission on low-bandwidth networks.
We have already known the difference between the mainstream and the substream. Therefore, how to calculate the daily storage capacity of the camera? This is a frequently asked question. We will draw a summary and find an easy method.
The camera code stream or the bandwidth of the monitoring video stream is divided into mainstream and substream. The mainstream is used for storage, and the substream is generally used for preview. Therefore, the video that everyone sees during playback has higher quality than that seen during the preview. Also, the bit rate varies with different resolutions/frame rates and picture effects.
Different coding and compression algorithms lead to different H.264 and H.265 bitstreams. The current mainstream encoding is H.265, which can save nearly half of the transmission bandwidth and storage usage compared with H.264.
Hard disk capacity refers to the storage space of the hard disk. In general, there are 1T/2T/3T/4T/6T, 1T=1024G, 1G=1024M. It should be noted that the actual capacity of the hard disk for video storage is 90% of the total capacity with a capacity factor of 0.9. Why?
Smart H.265+ is the optimized implementation of the H.265 codec that uses a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structure and intelligent noise reduction to deliver high-quality video without straining the network. Smart H.265+ technology reduces bit rate and storage requirements by up to 90% when compared to the H.264 video compression standard.
The HDCVI DVR uses Smart H.265+ video compression to reduce bit rate and storage requirements by up to 70% when compared to standard H.265 video compression. Smart H.265+ is the optimized implementation of the H.265 codec that uses a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structure and intelligent noise reduction to deliver high-quality video without straining the network.
QVR Pro, the professional surveillance solution on QNAP NAS, includes 8 monitoring channels, allowing users to quickly build a home surveillance environment hosted on the QNAP NAS without any extra software required. Businesses can easily expand the number of monitoring channels up to 128 by purchasing QVR Pro licenses to deploy a large-scale surveillance project. QVR Pro uses an independent operating environment on the QNAP NAS, and by leveraging the storage expandability of the NAS, surveillance videos are safely stored for on-demand playback. The enhanced QVR Pro Client cross-platform software allows for rapid multi-channel playback and can support simultaneous play multiple 4K network cameras. Synchronous playback can focus on moving objects, while the diversified event notification setting ensures all urgent events are delivered. QVR Pro Client is available for mainstream operating systems on desktop and mobile, making surveillance management more convenient.

Log on to the device, click the Setup tab, you can configure the DVR settings. As the DVR has built-in storage, old footage could be cached in the local storage. The DVR may upload old video/image files, making it hard to verify whether your configuration is correct. If possible, please disable or remove DVR's local storage first. You can also delete all old footage and set the local disk to be read-only. You can change it back after you have finished configuring cloud recording.
The Bit Rate is a little tricky. Setting it too high will use too much bandwidth, thus dramatically slow down your network, causing failed uploads; setting it too low will affect the video quality. You can use our bandwidth calculator to estimate the bandwidth. Visit www.cameraftp.com, click Pricing, and then customize a service plan. See the screenshot below.
The above two screenshots have very similar functionalities. You can click Encode to set video/image parameters; click FTP to configure FTP settings; click Video Detect to set video motion detection settings; click Storage to set storage devices.
As the DVR has built-in local storage, and it can cache a lot of data. This may cause the DVR to keep uploading old footage. In order to make it easy to configure for cloud recording, we recommend disabling the local storage, or delete all local files and make the disk read-only while you are configuring the DVR. After you have finished configuring the DVR, you can re-enable the local storage. You can try to disable the local storage from the following screen:
For video recording, you need to configure the video parameters. For the Stream Type dropdown, please select "General" if you want continuous recording; otherwise, select Video Detect (or Motion Detection). The video parameters should be based on your CameraFTP subscription. The bit rate is a little tricky, please refer to the bandwidth calculator in Section 2 of this document. For image recording, please click "Snapshot".
