The internet does not have anything to do with the system, other than remote access IF you set it up. An sd card capable camera allows for redundancy recording to the NVR and the camera as a “local” file. As noted, if something happens like theft or hardware failure (more likely) to a router, switch or NVR hard drive, the camera will save recordings even if part of your network is not working.2) If internet is lost will it still save pictures to the card?
I forget because I do not use this feature but don't you have to manually enable a setting for the SD to work in this manner?If you are using a Dahua NVR, and recording to the SD card as well. If the network goes down, it will continue to record to the SD card, then when the network comes back online, the NVR will download the missing video from the SD.
Most likely, but since I don't use an NVR, I'm just guessing.I forget because I do not use this feature but don't you have to manually enable a setting for the SD to work in this manner?
anyone know how to turn it on?then when the network comes back online, the NVR will download the missing video from the SD.
I have Samsung EVO Select 128GB. Works fine. All reputable manufacturers will work. Stay away from no-name/knock-off brands.and what sdcards dahua is working with (producer/model/size)?
anyone know how to turn it on?
