Here's my sad tale of rebooting redux...
I purchased by first four Hikvision DS-2CD2032-I cameras from Costco (rebranded Swann units) for $350.00 a pair. But it wasn't long 'till the AliExpress siren sang her sorry song to me and it went like this: at $90.00 each, the AliExpress units were essentially 2-for-one when compared to the Costco units.
So I was seduced and I ordered one DS-2CD2032-I unit from AliExpress as a test. It worked fine! So I ordered another two more units from the same AliExpress seller; again no problema! So I ordered four units from the same seller and, once again, they functioned like champs!
Thusly -- having NO FEAR -- I ventured forth unto the hinterlands of China and ordered three Hikvision DS-2CD2332-I cameras from the same AliExpress seller; opps! Big problems this time. After initial configuration each of these 3 cameras seemed to be caught in an endless reboot loop, where each camera would be fine for 4 or 5 minutes and then there would be unreachable...then each camera would come back online and seem to function perfectly...but only for 4 or 5 minutes...and then they rebooted yet again.
Each of these cameras arrived out of the box with firmware 5.2.8 (build 141201) installed and (although the serial numbers indicated that these were Chinese market cams) each camera allowed selection of English (along with many other languages) at the login screen.
Henceforth consigned to a seemingly Sisyphean task by the Camera Gods I spent A LOT OF TIME trying to resolve these random reboots, yet despite many hours of labor I failed to make any progress. I GAVE UP. I had had it. Done. Finito. Kaput. Dejected and forlorn I ultimately chose to pay CBX to install 5.2.5 firmware on each camera. I could have done it myself but I was sick of looking at those f#$%kin' cameras and I didn't want to take a chance that I might screw up one of the units...I didn't want to hassle with the seller...I just WANTED IT TO BE DONE AND OVER. CBX logged on with Teamviewer and used PUTTY and
TFTP utilities to install 5.2.5 over 5.2.8.
As a result, installing 5.2.5 over 5.2.8 did the trick and I now have 3 fully functional DS-2CD2332-I cameras. But despite purchasing and receiving 7 fully functioning cameras from the same seller on AliExpress the last 3 were probably rendered defective by a bad firmware hack.
I did end up filing a dispute and the vendor's rebuttal stated "I don't know your usage is correct!" As a result of this comment I'm wondering if...maybe...I lost my ability to configure Hikvision cameras which I had honed so well while configuring THE FIRST SEVEN CAMERAS I BOUGHT FROM THIS SAME VENDOR.
