hello i'm trying to record both motion and "regular", so i can scan/playback the parts when motion detected, but when it switching from regular to motion, it cutting/skipping 1-3 seconds here is sample that i combined the 2 files: https://drive.google.com/file/d/0B4zVggF5JuNyM21uWWhxMUJlbms/view?usp=sharing is it the same way in yours too? how to fix this? thanks

And what did you actually expect? You do have more resolution. WHere you have 704x576, now you have 960x576. Did you think that changing the DVR would make your camera see wider? The DVR just turns the analog video signal it receives from the camera into 0s and 1s. You do have more resolution now, so you have more detail. But changing the DVR won't change the angle the camera is seeing. i thought the D1 dvr using part of the sensor of 960h camera, sometimes this exist for example dahua 3mp ip camera using the whole sensor only when using the maximum resolution. i know more cases when cameras cropping part of the image, sometimes in order to remain the aspect ratio(using 4:3 sensor to shoot 16:9 1080P video) or sometimes it's a hardware limitation. why should it not be wider? 960x576 IS WIDER than 704x576. the common sense tell you that if you get a 960x576 native resolution camera, you should get 960x576 dvr. now, you might say that i had before d1 dvr, so it probably made the picture looks "narrower" than real ("make people taller"), but this is the opposite case. the D1 dvr looks natural, real aspect ratio, native, and the 960h dvr looks stretched to wider, even the 960h dvr is matched to the camera resolution and the d1 dvr is not. there are no extra details using the 960h dvr. how can it be that 704x576 capture the exact field of view like 960x576? they are different aspect ratio. if sony claim their sensor and chipset is 960x576 NATIVE PIXELS, and when you use 960x576 dvr it looks too wide, stretched, and not showing any additional details, the conclusion is that sony are lying about the true pixels, they are not 960x576 pixels, they are something else and has been stretched now, where is the "extra details"? those 2 pictures took from the same dvr, one at d1, other on 960h mode. d1 even looks a little more detailed and the natural not stretched: http://i.cubeupload.com/IDnf0K.png http://i.cubeupload.com/nWgGXk.png look also in this review on the 960H field of fiew part http://ipvm.com/report/hd_analog_shootout

yes, but i wanted to switch to 960h dvr and it looks like it's not real 960h because it's the same corners, same photo, just stretched. http://ipvm.com/report/hd_analog_shootout

hello i got today a 960h dvr that's looks like a fake to me what is fake? this is photo that was taken from an older d1 dvr http://i.cubeupload.com/WOMAtF.jpg this photo was taken from the new 960h dvr http://i.cubeupload.com/ETihhx.jpg as you can see, this is EXACT same photo, SAME CORNERS, just stretched now, there are two options: 1. the D1 dvr was compressed the 960h sensor into d1 resolution 2. the 960h dvr was taken a d1 and stretched it into 960h resolution to me, the d1 photo looks more natural and the 960h looks too wide like it was stretched and it's a fake 960h dvr. what do you think? any way to test this? here is a comparison http://i.cubeupload.com/qHBK1W.png

hi i need to get a camera, will be on the street outside my house. it's analog ccd camera. the light at night is not that good. i have option to upgrade the lens from f2.0 to f1.2, a little more expensive. my concerns are: 1. how is the sharpness of the f1.2 (it's china lens, not brand) 2. i live in country with lots of sun. i concern that it will be overexposure at day light what do you think? thanks

i forgot to update. the problem was too large hdd. making 500gb partitions solved it

does all analog cameras fit to all dvr?
akv replied to akv's topic in General Analog CCTV Discussion
thank you -
for example a camera has 960h resolution, can i connect it with dvr that support only d1, so the dvr will accept the camera as d1? or it they will not work anyway? thanks
