The device price is a bit steep but when you get it setup the quality shows, the optical zoom is a good feature but not something you will use a lot once all setup, compared to the G4 Bullet this stands alone for night time quality, the bullet doesn't even come close and if you have motion sensor lights then the night quality is almost like daytime, the field of view is great for driveways and open spaces like courtyards, the smart detect for vehicles and people saves a lot on storage space, if these were cheaper I would buy more.
