Q: Where is the recording data stored?

A: All recordings and data are stored locally on the recorder's hard drive, ensuring privacy and no ongoing fees.

Q: How close do the cameras need to be to the home base in order to connect and record? I am looking to have one camera about 200 ft away from the home base -- will it still connect?

A: Thank you for the question and happy to help. Our systems are tested up to 250 feet with line of site, but as you add structures, trees, etc the distance shortens. More dense obstructions like brick and concrete limit that further. You might confirm Best Buy return policy on opened boxes and then test the setup knowing you may return. We also offer wired solutions that can run that distance with extension cabling. Thanks, Night Owl SP Digital Support Team
