Sentinel 4K NVR Ultra HD Wired Additional Security Camera

Had to replace 5 cameras at my own cost after professionally installed cameras fried in the first storm (despite protection coverings and proper professional wire). Defender refused to replace - even though I’ve purchased lots prior for rentals. As I already had the other remaining working cameras and nvr I opted to replace the broken cameras at my expense vs purchasing an entirely new system). Will never purchase with defender again though going forward. Terrible customer service and product backing.
