Based on the Current H.265 Video encoding standard, Smart H.265+ adopts some available video encoding techniques and integrates these key techniques with Dahuas advanced video content analytics technologies. Figured out I could test the question w/o another camera out on by the street. Bandwidth-savings-wise, Smart Codec wasn't really doing anything for me, anyway. However, in a very high motion nighttime test (generated by using a stage laser), bitrate actuallyincreased when using Smart H.264+, unlike other scenes, as well as other smart codecswe have tested. I also have IVS for entering and leaving my parking slot, but IVS is not neccessary for me. IPVM is the leading authority on physical security technology, including video, access, weapons detection, and more. 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. The noise of the surveillance video is usually high when the application area is uncertain and the light condition is poor. Tests were performed at 10 FPS, ~28-30 quantization average (before turning smart codecon). I made some settings changes regarding which streams are used for.

The changes are primarily on the encoding / camera side with decoding remaining the same for the VMS.

Special equipment is required to take advantage of H.264+ Smart Codec. After smart codec is enabled, the device would stop supporting the third bit stream, ROI, and smart event detection, and the actual interface shall prevail. Setup Suggestions. All, as promised last night, here is a quick clip showing the difference between SMD 3.0 vs SMD 2.0 with regards to IR (Auto vs Smart) on a 5442 Vari Turret. JavaScript is disabled.

I believe they're independent of each other so yeah test SMD not IVS. Generally, only I-frame can realize the random add/insert function. My other 5241-Z12 had a build date of October 2019.

SmartPSS - Dahua Technology USA Inc I never messed with it because IVS was soooooo much more reliable than motion detection (at least for my scenes), it wasn't an option to lose it. SMD 3.0 dahua | Page 3 | IP Cam Talk Smart Codec works fine for me. In the case of the 11/23 FW its exactly the same settings except Smart IR is on. Maybe you can set that to a large enough value to cover the GOP length. Accoring to Dahua "Smart H.265+ technology is a collection of intelligent encoding algorithms developed by Dahua technology based on H.265. JavaScript is disabled. 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. This camera adopts the latest starlight technology and displays better colorful image in the environment of low illumination. *** * ** * ***** Impact). For different motion surveillance environments, Smart H.265 can generally enhance the compression rate. Dahua Releases Smart H.265+ Encoder - A1 Security Cameras Legislation passed on May 24th 2018, Dokumentacija Deklaracije o usaglaenosti Evropske Unije, Statement on adding Dahua Technology to the entity list, Declaration of Metal Conflict-Free of Dahua Technology. To reduce the bit rate and guarantee encoding video quality, compared with the single frame reference structure of standard H.264 and H.265, Smart H.265+ adds a more flexible reference frame structure. For surveillance video, since the moving object only appears in the specified period and lasts for short time, Smart H.265+ can remarkably enhance compression efficiency. With the surveillance operators pursuing/moving to HD/UHD, the surveillance video of high resolution and large bit rate has become one of the main challenges. During the day, the Dahua 4MP camera's bitrates were significantly lower than its Hikvision equivalent, with Smart H.264+ both on and off. of course if you have the camera set to smart codec and the Syno SS set with smart codec off, things can get wonky. are there any downsides to using Smart Codec? IPC-HFW3549T1-AS-PV-0280B. then you are having a better experience with DS Cam (iOS) and SS client (OSX) then I am. Bitrate reductions with Smart H.264+ on vs. off varied from about 35% in some scenes to ~90% in still, well lit scenes, seen in the chart below. For example, human visual perception of indoor objects is more sensitive than outdoor objects. ******* *** camera ******** ** ** ********, ** takes **** ********* (***** * *** more *********). To meet the characteristics of video surveillance, Smart H.265+ adopts some key video encoding techniques that can be flexibly added/deleted or combined according to different applications and products. I still experience the delay in SMD. PDF Dahua AI Coding Technology Following the differentiated encoding strategy described in figure 2 can be adopted to improve the overall performance: quality of moving object F needs to be guaranteed and the quality of background area B can be lowered, thus reducing the bit rate of background area and as a result to lower the overall system transmission bit rate. *** *******, ******* ** setting *********** ** '******' *** *** whole *****, ** ***** ** *** hallway ***** *****, *** ****** ******* compression ** *** ****** ******* ** low (****** *******), ** ******** ******* quality, *** ********* *********** ** ****** background *****.

When I brought up Live View on the Synology SS the two cameras set for Smart Codec would take 2-3 seconds before video would appear. Even distanced vehicles at the edge of a 5442 FOV (i.e. To meet the characteristics of video surveillance, Smart H.265+ adopts some key video encoding techniques that can be flexibly added/deleted or combined according to different applications and products. The I-frame has a much bigger storage load in the video bit streams compared with P-frame. Make sure to select minimum of HD although I did upload native res which will be available when YT finishes processing as 2K. You must log in or register to reply here.

Smart H.265+ is not a new technology, but an optimized implementation of H.265. It further adds to the storage and transmission cost and increases the whole cost of the surveillance system.

Many Techniques of Smart H.265+ are beyond the video encoding standard framework which ensures the Smart H.265+ technology does not conflict with the H.265 encoding standard. Please first review our: 'Normal' codecs, like 'regular' H.265, set one compression level, one I frame interval, and one frame rate. What I haven't tested thoroughly, and really what will make or break it, is how it behaves in high-motion scenes. Just like proper gain control smart codecs is another 'smart' initiative meant to reduce network traffic while optimizing video streaming. What I haven't tested thoroughly, and really what will make or break it, is how it behaves in high-motion scenes.
