Frame vs CIF - Digital Video Recorders - CCTVForum. com Frame, in this context, is abbreviated from 'Full Frame' and is the higher resolution setting, equivalent to 4CIF It will offer you a higher picture quality from each camera, but at the sacrifice of hard drive space and or recording frame rate (also referred to as IPS Images Per Second by some developers in China)
HikVision FPS vs i-Frame vs Disk Station performance I tried setting my FPS and I-Frame settings to the same (6 FPS and 6 for I-Frame interval) and my Diskstation (DS-213J) started to peak on CPU usage hovering around 90% (or more) most of the time I then left my FPS settings at 6 and changed my I-Frame settings to 12, and the Disk Station CPU seems to be in the 50-70% range most of the time
I-Frame intervals settings - IP Megapixel Cameras and Software . . . Changing I-frame intervals can affect the size of the P-frames and actually result in higher bitrates and or lower picture quality My suggestion is to experiment Note the original settings, then change encoder settings and observer the result
High resolution low fps or low resolution high fps - IP Megapixel . . . What is an acceptable Frame-rate? The standard frame-rate for video systems is 25 fps (PAL) or 30 fps (NTSC) The human brain processes images perceived by the eyes at 24 fps as fluid motion As the frame-rate keeps dropping the brain registers stutters to the fluid motion, with the stuttering becoming more pronounced at 10 fps and below
Hikvision skipping frames when playing back recordings For the reference frame by four, every 4th frame is to be used as a reference frame for encoding 1,2,3, and 4th frames Then only 4 th frames need to be decoded and reconstructed, skipping 1,2,3rd frames at the NVR side Thus 8 and 16 fast forwarding can be achieved without clocking much faster
Shutter speed AND frame rate - Test Bench - CCTVForum. com I'm still hazy about the shutter speed and frame rate If 1 shutter cycle produces 1 image = 1 frame and you have the shutter speed cranked to 100,000 (100,000 frames per second) but the camera only sends 30 fps how does the camera know which 30 of the 100,000 to send? I just haven't seen anything that explains it
Advice on front door camera placement - CCTVForum. com This is a tricky spot, due to the long, narrow entrance to the door, and the window above the door limits how far down you can put a camera If you could mount one between the door and window, or just to the right of the top of the door frame, that would be ideal from a face capture perspective, but it's not so aesthetic or wife-friendly
Milestone and hikvision dropping frames problem. . . Make iframe on the camera the same as the frame rate, so if it's 20, make iframe 20 Try increasing the max bitrate, maybe to 6144 (lower compression means less CPU work needed) Last thing it could be is your network, so you Task Manager, Resource Manager to see the network on Win7 of just the performance tab in Win8
IPS v FPS - Digital Video Recorders - CCTVForum. com From what most high compression ration codec does is they encode key frames or full frame only at interval, and then record the changes inbetween these key frame, thus achieving high compression e g out of 25 images, only 1 image is save in full, and 24 images only save the moving differences Mpegs (1,2,4), H 26x, wavelet, etc
Bit Rate Settings? - IP Megapixel Cameras and Software Solutions . . . Bit rate is the h 264 way of specifying compression Back in the old days, like 3 years ago, most cameras were MPEG or MJPEG and you specified compression as a percentage but with h 264 you do it by bitrate and the lower the number, the higher the compression, meaning the camera and NVR work harder to decode the compressed stream, but takes up less network bandwidth and space, but you get
