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. Dynamic GOP is great for continuous recording but be very careful on motion based recording. Sadly, a 5 time factory reset did not fix the changing of shutter and gain switching back and forth between SMD and IVS. By taking reference frames and applying them to refreshed frames the Smart Codec eliminates the need to transmit data for an unchanged image, or parts of the image where there is no movement. During the day, the Dahua 4MP camera's bitrates were significantly lower than its Hikvision equivalent, with Smart H.264+ both on and off. In both cases I look directly at the camera. I'll give it a go. For a better experience, please enable JavaScript in your browser before proceeding. Because the cam is doing the detection but the VMS is getting the metadata to tell it to records. The I-frame has a much bigger storage load in the video bit streams compared with P-frame. they usually just either stream garbage images or they fail to "active" after you change something on the SynoSS side, the camera always stays to what I left it at. The surveillance environments usually need 24/7 recording, the noise is generally high, and especially at the night the noise is extremely high. IPVM is the authority on physical security technology including video surveillance, access control, weapons detection and more.

Which one I should use on my camera? However, it was less effective at night, with reductions of 35-60%. Smart H.25+ technology is a collection of intelligent encoding algorithms developed by Dahua Technology based on H.265. Combined, these features can effectively provide a substantial bit rate reduction (the number of bits per second that can be transmitted along a digital network) in the recorded video. A Comprehensive Guide to CCTV Camera Installation, Dahua Cameras and IP Surveillance Systems. Note that despite this, the Dahua camera's bitrate is still lower than Hikvision. (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. 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? It's hard to say. I'm curious about this too. In the above figure, the 2nd P-frame references both the IDR (frame 0) and the 1st P-frame. 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. This keyframe compression technology can be used to restore video streams from different points of time.

IPC/Camera Configuration - Dahua Wiki 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. Keep in mind that traditionally, I-frames are every second or two so the wait is not normally that long. 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. I also have IVS for entering and leaving my parking slot, but IVS is not neccessary for me. The firmware automatically adjusting iframe rate to "intelligently" optimize performance. Smart H.265+ is a collection of intelligent encoding algorithms and contains many encoding techniques. Range of 4 - 16.67 (1/60 to 1/250), no Auto Iris, gain left at 0-50 (default) and In the case of SMD 3.0 FW IR is set to Auto.

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. This started out as me asking about Dahua's. Brand new camera too.. 1) Did it prompt you to download the new webplugin ? Tests were performed at 10 FPS, ~28-30 quantization average (before turning smart codecon). after that what other options to do you have configured ..etc. For a better experience, please enable JavaScript in your browser before proceeding. SSA automatically regulates the exposure parameters to improve image quality in a backlit scene, especially in scenes with trac lights or headlights. Firmware is available on each camera's individual page (see the HDBW54X1 page for example). And if we add the variant of ROI to the entire screen to everything discussed. When using a VMS to switch between streams have you noticed any unusually long delays? We have not seen any issues integrating with VMSes to date. Only if I turn it back on and do a screen video capture. I have no idea what you're looking for, but I'm hardly going to wade through God-knows-how-many pages of SS configuration to find and report every last setting change I might have made. 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. In this Guide, we explain what smart codecs attempt to do and the most common implementations, covering: To understand this, you must have a good understanding of codecs, compression and bandwidth variations. 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? not the central point of focus) have picked up very well, quicker in most cases and on point i.e. When there is no motion, the bitrate goes down to the double-digits. Results have shown that most h.264 compliant recorders can take advantage of this technology. Step 3. Third-party cookies may collect data outside our websites as well. It includes many key techniques of encoding technology. IPVM is the authority on physical security technology including video surveillance, access control, weapons detection and more. On Smart Codec I set. Smart H.264+ reduced bitrates by as much as 90% in still, well lit scenes and about 30% in busy daytime scenes. 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). In my limited testing, Smart Codec uses WAY less data with little to no loss in quality in low-motion scenes.

Please first review our: 'Normal' codecs, like 'regular' H.265, set one compression level, one I frame interval, and one frame rate. This camera adopts the latest starlight technology and displays better colorful image in the environment of low illumination. //]]>. Compared with other video files, typical surveillance video has the following characteristics. IVS - Dahua Wiki Off / On (4 Zone) Electronic Image. 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. Support. "Smart Codec" was once seemingly a marketing buzzword, but in 2023, almost all new camera models include this technology.

Dahua H 264 vs H 265 vs H 265 Smart Coding use IR mode ON 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. 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. The following firmware versions were used in this test: Firmware was also confirmed working in the Dahua HFW44X1S. I'm using motion detection (human and car). I just did a test with some fast motion in front of one of my 5231 cams (all with VBR Best, bitrate maxed out, and 15fps): I can't playback any recorded footage with H265 Smart Codec in. I made some settings changes regarding which streams are used for. However, Hikvision offers H.264+ on a broader selection of cameras (nearly all current models), including low cost and high end models. The smart codectrend continues, with Dahua adding Smart H.264+ to many of their models in new firmware. 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. Dahua's Smart H.265+ takes this one step further, reducing bitrate drastically. I could see lower bitrate in static scene and higher when car appears.

Dahua's new H.264+ Smart Codec does save bandwidth compared to H.264, and the only special equipment required is a camera that can take advantage of the H.264+ Smart Codec. 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. Smart H.25+ technology is a collection of intelligent encoding algorithms developed by Dahua Technology based on H.265.

We expect to see more and more manufacturers to do similar as the bandwidth benefits are obvious and significant. An advanced compression codec like H.265 results in a lower bitrate and less need for storage. It is hard to find the balance between these two factors in traditional noise reduction techniques. Scene adaptive encoding strategy is to implement a differentiated strategy based on smart scene analysis which includes the analysis of light/noise/motion conditions and enjoinments. After purchasing a new PC running Windows 11 Pro, installed Smart PSS, imported the exported database from the old PC, and all the cameras and NVR show expected settings, IPs, etc. AI CODEC vs Smart Codec? | IP Cam Talk DAHUA IP 2 MP Dome Camera, Fixed Focus Control, Smart Codec, CBR/VBR, Buy Online with Best Price. Finally, as discussed above, the Dahua camera's bitrate increased in our high motion low light scene with Smart H.264+ on, while Hikvision's bitrate drops by ~12 Mb/s, about an 80% decrease.
