I have 4 DVR's F6 series and We just bought 2 new HD 3.0 DVR's We could watch all of our cameras from all of the F6 series through 1 application simultaneously with the HD CMS App but the HD 3. uses X-CMS App . Do I now need 2 Computers 1 for each App?

Asked by: Jonscomputers
Your Night Owl device is not compatible with all of our applications. Rather, it is only compatible with a specific App for remote viewing. We do have several Apps in the App Store and Google Play Store. However, these Apps are intended for specific devices, not universal. If you have two or more systems that use different apps, then the cameras from each system cannot be viewed on one screen at the same time. Thank you for choosing Night Owl!

I have an older system and when the power goes out I have to go through the set up to get the cameras back up and recording. Dose this system re boot and start recording when the power comes back on

Asked by: tcop
Yes, this system should power back on and revert to your saved settings when power is restored. However, you will want to protect against damage that can be caused by power surges and spikes. We would strongly recommend a surge protector for the DVR, cameras and your router! Thank you for choosing Night Owl!
