Dahua H 264 vs H 265 vs H 265 Smart Coding use NIGHT COLOR MODE Select Smart Plan from the menu on the left. Hopefully, as the technology matures cameras will be able to decipher noise from movement to reduce unneeded bandwidth consumption. However, Hikvision offers H.264+ on a broader selection of cameras (nearly all current models), including low cost and high end models. Which one I should use on my camera? 'Smart' codecs change one, two, or all of those, reviewed inside. The virtual I-frame technique implementation ensures the P-frame can appoint the previous IDR as the only reference frame (In the above figure, the 5th P-frame can only reference the 0th IDR) so that it can be added/inserted whenever necessary instead of relying on the previous P-frame to decode. I haven't experienced any problems with dithering, grayed out frames, and other encoding problems when viewing live streams. No way to access stream on the camera. The big question in my mind is, if we use Smart Codec and maximize the bitrate, is the resulting quality in high-motion scenes comparable to something like VBR-Best with a similar bitrate and iframes every second? ***, ********** ******* is ********* *** ******** ** ***** and ****, ** ******** ** **** specialized ****** ***** ***** ** ****** bandwidth (**** ********* ************** ********' *******) *** ******* ****** ***********. Based on the video analytics technology, the Smart H.265+ technology generally separates/distinguishes the motion area from the background area and adopts different noise reduction levels for motion and background (see figure 7).

Bandwidth-savings-wise, Smart Codec wasn't really doing anything for me, anyway. Video stream recording will not start until Surveillance Station receives the first keyframe. Smart codec is a function in most Amcrest cameras which aim to reduce bandwidth consumption without losing visible image quality by intelligently increasing compression where it will not make a visible difference in the scene. What VMS were you using? Generally speaking, the improvement rate of compression efficiency is high if the contents in the surveillance scene are simple and the amount of moving objects is small. PDF Dahua AI Coding Technology For a better experience, please enable JavaScript in your browser before proceeding. Smart H.265+ is not a new technology, but an optimized implementation of H.265. Smart Coding technology encoding deploys Group of Picture (GOP) Control; Frequency Divided Filter (FDF); and 3-D Multi-Process Noise Reduction (3D-MNR) to achieve a lower bit rate for recorded images without degrading the captured and transmitted video stream. Generally, only I-frame can realize the random add/insert function. I was trying to tell you to go into the ". Normally only the moving object (F) is the main interesting area and the image quality need to be guaranteed. ********* * hallway *** ** ***** *** ** hour. I'm using motion detection (human and car). We leaned the hard way that VMD does not work when your I-frame interval is too high, we had an incident and no video because there where not enough frames to compare for VMD to kick off recording. If it is highlighted in yellow that means IVS is selected. How to Add a Dahua IP Camera and NVR to a Switch Encode Settings Overview How to Setup Encoding Making the Most of Bit Rate Need More Recording Space Understanding the Condition Settings Some of these settings are better left alone in order to keep a consistent image quality; Brightness Contrast, Saturation, Sharpness, and Gamma. On Smart Codec I set. that modifies the encoding compression algorithm in standard H.264 video streams, yielding up to 70 percent improvement in bandwidth reduction to reduce bandwidth has been released. The Scene adaptive encoding strategy can not only guarantee the human visual perception of the surveillance scene but also improve the encoding efficiency. There has to be a trade-off for the performance increase. Once you have logged in, navigate to the Setup tab. Just like proper gain control smart codecs is another 'smart' initiative meant to reduce network traffic while optimizing video streaming. Is this an out-of-band request that operates on an existing RTSP stream, or is this made when creating a new socket? Dahuasecurity.com uses cookies and similar technologies. Yes, by default, IIRC, SS has everything set to "balanced" and "balanced" is set to the main stream. Ordinary surveillance video encoding only takes a single frame (I-frame or previous frame) as a reference frame. I am trying bench test a similar cam but have. The I-frame has a much bigger storage load in the video bit streams compared with P-frame. Theory: Utilizing a cognitive encoding method, Smart Codec uses several technologies in order to reduce the amount of space and bit rate a video feed consume. Enable javascript to view IPVM. We have asked Dahua whether there are plans to bring Smart H.264+ to other models, such as the Lite or Ultra lines and will update this report if/when they clarify. ** ****, ****** *** ***** ************* include ***** ****** ** ** ***** some ** ***** *******, **** **** implementing **** ** *** ******** ** their ****. What I haven't tested thoroughly, and really what will make or break it, is how it behaves in high-motion scenes. Note that despite this, the Dahua camera's bitrate is still lower than Hikvision. In the case of the 11/23 FW its exactly the same settings except Smart IR is on. Dahua Technology - Leading Video Surveillance Solution Provider with CCTV Products, IP Camera, PTZ, HDCVI products, NVR, Intelligent Building, Intelligent Transportation and Software - Dahua Technology. I think it still works even with SC, but user manual says otherwise. As you can see, Smart H.265+ decreases storage and bitrate up to 90% over H.264! JavaScript is disabled. Since typical surveillance video is static or has minor changes for the majority of the time, Smart H.265+ adopts the strategy of dynamic GOP and only inserts I-frame when there are big changes and an additional I-frame is necessary.

I did this on my more recent 5241-Z12 though and the settings for the same location are completely different, so there could be differences in the hardware between an older 5241-Z12 and a newer 5241-Z12 that has a build date of October 2020. Or the other hand, its key techniques can be applied to H.265. but you don't seem to feel the need to confirm such things. Smart Codec is the optimized implementation of standard video compression (H.265 & H.264) 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. ************ ******* *** ****** ************ ** distinguish ******* **** ******** (* ****** walking, * *** *******, ***.) In both cases I look directly at the camera. Keep in mind that traditionally, I-frames are every second or two so the wait is not normally that long. According to the JND model (Just a Noticeable Difference Model), the human visual perception of an object is different.

The big question in my mind is, if we use Smart Codec and maximize the bitrate, is the resulting quality in high-motion scenes comparable to something like VBR-Best with a similar bitrate and iframes every second? The Smart H.265+ technology does not require a hardware upgrade or replacement, but a firmware upgrade which can greatly enhance the product features without adding additional cost.
