Security System Supplier | Security System Installer | ATSS Technology Solutions Provider | 2023, All Rights Reserved. I still experience the delay in SMD. It is necessary to control the noise and implement a better-controlling strategy for video encoding. Some Cameras & VMS allow for I-Frame insertion request to be sent to demand an I-Frame immediately. How to set up the Dahua IVS Tripwire SecurityCamCenter.com The smart codectrend continues, with Dahua adding Smart H.264+ to many of their models in new firmware. It really all comes down to how quickly/effectively Smart Codec ramps up the bitrate and iframes in those situations. on the syno side what does your config look like ? Better adequate for slower network speeds Here is an comparison of Main Stream vs. Sub Stream: MainStream Sub-Stream This page was last modified on 30 June 2016, at 05:23. are you running it with generic dahau or the cam specific selection ? Dahua Smart H.264+ Tested - IPVM Legislation passed on May 24th 2018, Deklaracje zgodnoci UE w jzyku polskim/ EU Declarations of Conformity Documents in Polish. Most existing hardware and software can play its bit streams. Tests were performed at 10 FPS, ~28-30 quantization average (before turning smart codecon).

Even distanced vehicles at the edge of a 5442 FOV (i.e. Note that despite this, the Dahua camera's bitrate is still lower than Hikvision. I'll give it a go. Smart Codec. Is this an out-of-band request that operates on an existing RTSP stream, or is this made when creating a new socket? Brand new camera too.. 1) Did it prompt you to download the new webplugin ? Tried other browsers. Step 3. The traditional noise reduction strategy is generally to take the video scene as a whole and intense noise reduction techniques can delete some video details during noise reduction. The link to the Surveillance Codec Guide is now working. 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. Smart H.25+ technology is a collection of intelligent encoding algorithms developed by Dahua Technology based on H.265. If a keyframe is missing, then the video stream from that specific time cannot be restored. (e in b)&&0=b[e].o&&a.height>=b[e].m)&&(b[e]={rw:a.width,rh:a.height,ow:a.naturalWidth,oh:a.naturalHeight})}return b}var C="";u("pagespeed.CriticalImages.getBeaconData",function(){return C});u("pagespeed.CriticalImages.Run",function(b,c,a,d,e,f){var r=new y(b,c,a,e,f);x=r;d&&w(function(){window.setTimeout(function(){A(r)},0)})});})();pagespeed.CriticalImages.Run('/mod_pagespeed_beacon','https://www.dahuawiki.com/News/H.264_Plus_vs._H.264','82dtZm2p5Q',true,false,'2xxUpsmPOQI'); Wind's blowing pretty good today, and the patio camera has a lot of trees and bushes in its view. Smart H. 265+ encoding technology which Dahua is also promoting, smart codec is more suitable for large scenes, especially for static scenes where it can achieve a larger proportion of compression. Functions Smart(H.265+ & H.264+) It effectively improves video encoding efficiency while guaranteeing video quality at the same time. During the specified period, the background of the surveillance video is static, or has minor motions. In this test we see how it performs and how it compares to Dahua's key competitor Hikvision and their H.264+ smart codecin day and night scenes, both lowand high motion. In this way, it can not only reduce the noise but also guarantee the ROI of video quality. Panasonic is now announcing 'smart coding technology'. 'Smart' codecs change one, two, or all of those, reviewed inside. My other 5241-Z12 had a build date of October 2019. It supports SD card storage, waterproof function, dust-proof function , complying to the standards of IP67. It still needs to get enough frames to compare. 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. I searched. The following firmware versions were used in this test: Firmware was also confirmed working in the Dahua HFW44X1S. 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. I expect a reduction of 20-50% in bandwidth over H.264. Dynamic GOP is great for continuous recording but be very careful on motion based recording. Last Updated Dec 13, 2022 11:10 AM "Smart Codec" was once seemingly a marketing buzzword, but in 2023, almost all new camera models include this technology. 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? As described in figure 3, a typical surveillance system implements fixed GOP, which means the interval between 2 I-frames is fixed, generally sets as 2 seconds. *** ****, *** ********* *** (******* ***** *********) *****. Figured out I could test the question w/o another camera out on by the street. During the day, the Dahua 4MP camera's bitrates were significantly lower than its Hikvision equivalent, with Smart H.264+ both on and off. here are the models of cams i'm using.[snip].

Without Smart Codec enabled they're instantaneous. We have not seen any issues integrating with VMSes to date. But please tell me. This supports the results of the experiment showing lower bit rates and also lower storage rates. However, Hikvision offers H.264+ on a broader selection of cameras (nearly all current models), including low cost and high end models. 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. Los DVR Dahua cuentan con la funcin de Smart Codec lo cual te permite ahorrar mucho espacio en el disco duro para almacenar mas cantidad de das gracias a la potencia de H264+ y el codec H265 con lo cual podrs almacenar hasta el doble de horas de video con el mismo espacio de disco duro.Si tienes dudas puedes dejarlas en la seccin de comentarios.Si quieres adquirir productos Dahua o Saxxon al mejor precio puedes visitar https://webyservicios.comDiferencia entre H264 plus y H265 en DahuaConfiguracin de H264+ vs H264 I don't think AI Codec is helping to save more space. Hopefully, as the technology matures cameras will be able to decipher noise from movement to reduce unneeded bandwidth consumption. Note that Smart H.264+ is available only on Dahua's mid-range "Pro" series, not their lowest cost or highest performance models. "Smart Codec" Yes or No? | IP Cam Talk This page was last modified on 19 May 2017, at 17:36. In the surveillance video, most of the time the video is static and the moving object/motion appears at the certain periods. but you don't seem to feel the need to confirm such things. After that, click on the lightbulb icon to enable the IVS feature. It can enhance the accuracy of the evaluation and raise compression efficiency. It is not in any way a new video encoding standard but an optimized implementation of the H.265. SMD 3.0 dahua | Page 3 | IP Cam Talk The software provides efficient device management, video monitoring and playback, alarm and analytic configuration . In the Video bit Stream, the frame size of the I-frame is usually times the P-frame size in order to guarantee the video quality. 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. 279 Share Save 20K views 4 years ago Los DVR Dahua cuentan con la funcin de Smart Codec lo cual te permite ahorrar mucho espacio en el disco duro para almacenar mas cantidad de das gracias. GOP length was get to ~300. Setup Suggestions. An advanced compression codec like H.265 results in a lower bitrate and less need for storage. Server side or camera side VMD? This started out as me asking about Dahua's. News/H.264 Plus vs. H.264 - Dahua Wiki IPVM is the authority on physical security technology including video surveillance, access control, weapons detection and more. 4MP Lite IR Vari-focal Bullet Network Camera > 4MP, 1/3" CMOS image sensor, low illuminance, high image definition > Outputs 4MP (2560 1440)@25/30 fps, max. 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. Ordinary surveillance video encoding only takes a single frame (I-frame or previous frame) as a reference frame. That's a terrible side effect!

Additionally, bandwidth actually increased in high motion nighttime scenes, an issue not seen in other smart codecswe have tested. Keep in mind that in surveillance video, most of the time the video is static and the moving object/motion appears at certain periods, Enlarging the GOP could effectively reduce the amount of I-frame in a set time-period. In addition, the Smart H.265+ and the Smart H.264+ cannot be used simultaneously with either an Analytics+ or an IVS feature. Enter your email address to receive the latest news & products information Enable javascript to view IPVM. 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. At some point, when the wind got to gusting pretty well, the image pixelated. The results have shown H.264+ does save storage and stream rates more or less around 20-50%. (function(){for(var g="function"==typeof Object.defineProperties?Object.defineProperty:function(b,c,a){if(a.get||a.set)throw new TypeError("ES3 does not support getters and setters. Dahua Oman on Instagram: "IPC-HDW2831TM-AS-S2 8MP Lite IR Fixed-focal Shifting of shutter settings you mentioned between SMD & IVS, Do not see delay in SMD detection across FOV (although as mentioned above, Human detection need work AI wise). The following table shows the real test results of encoding efficiency with Smart H.265+ enabled compared with Smart H.265+ Disabled. Video stream recording will not start until Surveillance Station receives the first keyframe. *** visible ***** ***** *** ****** ********* significantly. The higher the bit rate the more space it will take unless more heavily compressed in which case the quality will suffer. granted I used h.265 on everything. Only if I turn it back on and do a screen video capture. Smart Codec works fine for me. It had a chance to do so. 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.

I'm using motion detection (human and car). "Smart Codec" Yes or No? | Page 2 | IP Cam Talk I also have IVS for entering and leaving my parking slot, but IVS is not neccessary for me. The trade off has not shown any signs of failure in the video stream as they playback just as well as h.264. not the central point of focus) have picked up very well, quicker in most cases and on point i.e. What's the difference between them? Smart H.264+ is competitivewith Hikvision's H.264+, with lower bitrates on similar models in our tests, neutralizinga key advantage of Hikvision's in supported Dahua models. The more it's discussed the more questions arise on the technicalities. Yes, by default, IIRC, SS has everything set to "balanced" and "balanced" is set to the main stream. Dahua has optimized H.265 with their Smart H.265+ codec, providing up to 80% savings on bandwidth and storage over standard H.264. Resolution. //. SSA automatically regulates the exposure parameters to improve image quality in a backlit scene, especially in scenes with trac lights or headlights. 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. 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. In the case of the 11/23 FW its exactly the same settings except Smart IR is on. Wholesales IPC-HFW2531T-ZS/VFS - DAHUA DH-IPC-HFW2531T-ZS/VFS 5MP WDR In my limited testing, Smart Codec uses WAY less data with little to no loss in quality in low-motion scenes.
