[QUOTE="Askie, post: 1123135, member: 25982"] Thank you! Given that the NV780's field of vision is only to its sides, I'm intrigued by how it is able to detect someone approaching from its front, albeit at close range? Is it perhaps that, from such a close range, the IR you emit is strong enough to trigger the sensor through the "periphery" of its lens? Something like this: [ATTACH type="full"]18092[/ATTACH] Or might the anti-masking itself have something to do with this close-range detection? Is it something in particular about the BX-80's design that puts you off? Or just the fact that it is an old design? [/QUOTE]
