hello guys, I have few dahua dvrs with firmware 2016-1-23 and i want to downgrade to version 2015-3-17 because the newer version is not working properly on older PSS version. does anyone know if is possible to do downgrade on dahua dvrs ? if yes, can please explain how to do it ? ps. smart pss is not a solution. i want to downgrade the firmware

More details about your DVR model? Hello again, @tomcctv - i will try each software from there. @iTuneDVR - the dvr that not work properly (error images) is HCVR 4104 HS S3 with firmware 2016-1-23. i have another DVR which works OK and is HCVR 4104 HS S2 with firmware 2015-3-17. what im trying to do is to downgrade the eronate firmware 2016-1-23 to 2015-3-17 if is possible.

hello guys, do you know any good alternative software for PSS (pro surveillance system by dahua) ? i need a software which support Dahua Dvr's 4-16 channels. i have overr 550 dvrs online that need to be monitored online and the old PSS it makes troubles sometimes. dahua has another software now SMART PSS, but its worst then the old one. so if you have any software suggestions, please let me know. thank you!

just tell me how to solve this, if you know..

hi again, all dvrs are connected, but i see live only one dvr (4 channels)... after i check that 4 camers, i move on to other dvr. im asking if is any other similar software that support dahua dvrs.

@abdelm01 your questions are irrelevant. @Boogieman it crashes because of pss. it is not made for so many online dvrs.. i just need an alternative software for pss (dahua dvrs). does anybody know to answer to my question please? thank you!

not at one.. i have over 500 dvrs online in pss, but the operators are monitoring maximum 4 dvrs at once (one camera from each dvr). after they check the 4 drvs, they close the streaming and open another 4 dvrs.. anyway.. what i need is a similar software because the PSS is crashing sometimes

it doesnt matter. i just need similar softwares that fullfill my needs, that can handle over 500 online dvrs
