    I have an NVR 8 channel (RLN8-410) with 2 RLC-410-5MP attached. I have noticed that, after connecting my camera's to the NVR I am unable to access the cameras directly.

    In each camera I have installed a 128GB MicroSD card for 24 hour recording which runs in conjunction with motion recording on the NVR. How do I view the video on the MicroSD or have I wasted my money buying the cards and putting them in?

    The reason I ask is that we have recently had a theft on site and using the motion sensitive recording, the exact moment of the theft has been missed due to the recording not starting quick enough. I have therefore had to switch the NVR onto 24 hour recording which I didn't want to do given that the HDD has moving parts whereas the MicroSD doesn't and therefore more robust.

    I look forward to your reply.

    Just an opinion here but I believe an SD card has a limited number of write cycles whereas the HDD may not work forever it will surely outlive an SD card when considering write operations. Also, the HDD is spinning all the time anyway so not recording 24/7 will not extend its life significantly IMO. The major consideration with regard to recording 24/7 is how many total hours of recording will you have based on the capacity of your HDD.

    So are you suggesting to just record 24/7 on the HDD and do away with the MicroSD card? I thought the HDD would spin down when not used for a significant amount of time (like 30 minutes or so) so perhaps someone from Reolink can confirm which is the case; constant spin or spin down when not in use?

    I would also prefer to only use the HDD for motion as this will reduce the number of writes and consequent seeks when searching for data and it's also easier for exploring for when something does go missing whereas with the SC card I thought there's no choice, it's 24/7 but I maybe wrong here and until I get my alternative PoE so I can reference the cameras individually through my own internal network (which I can't through the Reolink NVR) I can't reassess my options.

    I hope Reolink monitors this forum and will give a definitive answer about whether or not the HDD will spin down if not being accessed. I would be surprised if that were true. I saw another post here about the apparent inability to access a camera's SD card if the camera is attached to an NVR. I have 5 cameras in which I had installed 64Gb SD cards. I later connected them to an NVR. I'm actually hoping that the SD card is not written to at all once the camera is connected to the NVR. It would be a waste of the SD card's useful life. So far I haven't gone to the trouble of climbing up to my cameras and unmounting them to get access to the SD cards and removing them.
    You can actually search for motion events on individual cameras using the NVR monitor – but it's pretty tedious. You can also search for events by connecting to the NVR using your computer and browser. I haven't really done any of that nor have I experimented much with motion sensitivity and masking settings in an attempt to make motion events more definitive. But it is something I will be investigating.

    Yes, I know you can do this but the playback is ONLY what is recorded on the NVR. There is no way of getting access to the SD card once connected to an NVR (Reolink's anyway) as the IP address is not internally accessible.
