It deters, records nothing, and everyone should know which · review
A pair of dome shells with semi-transparent bubbles and a red warning LED, each running on three AA cells. VisorTech publishes the dimensions and weight; there is no camera inside either of them.
The conclusion Two shells for the price of one real accessory. Fit them dark and away from close inspection.
A pair of dome shells, each with a bubble, a molded lens and a red LED. Neither contains a camera. Nothing is recorded, ever, and if an incident happens in front of one there is no footage of any kind.
VisorTech describes a semi-transparent housing, but the listing title speaks of a transparent dome: check the photo before relying on it. On a real dome camera you cannot see which way the lens is pointing, and that ambiguity is most of the psychological effect. A decoy with a clear bubble and an obviously hollow inside loses it at three meters; a smoked one does not.
Three AA cells per shell, not supplied, to run a blinking LED. It is a recurring cost for a feature that arguably makes the decoy less convincing: real cameras rarely flash while recording. Fitting them dark loses nothing.
High, at a distance, and away from anywhere somebody can stand and study them. A decoy works on a glance from the pavement and fails on inspection. Anything within arm’s reach should be a real camera or nothing.
A property with two secondary corners and real cameras already covering the approaches that matter.

Because a real dome camera is hard to see into, so the eye cannot tell where it is pointing. A shell with a clear bubble and an obviously empty inside gives itself away instantly; a smoked one keeps the ambiguity that makes the deterrent work at all. On this model the listing says both — a semi-transparent housing in the description, a transparent dome in the title — so check the photo before relying on it.
VisorTech publishes no runtime. It is a recurring cost for little benefit, and the shell is arguably more convincing with the LED off: running it without batteries loses nothing.
Only if you have two places to put them. Two decoys on one small frontage look like what they are; one decoy at a side gate and one at a rear corner, alongside real cameras at the front, is a coherent arrangement.

Two dome shells · blinking LED · indoor or outdoor · fixings included · records nothing
The two-shell box of the same BASI dome. Identical housing, identical blinking LED, identical absence of any camera — and a lower price per unit than buying two singles.
Best for: Two secondary corners on the same property, when the single has already proved good enough.
Dome shell · blinking LED · indoor or outdoor · fixings included · records nothing
A dome-shaped shell with a blinking LED and a molded lens, sold by a German lock and security hardware maker. It records nothing at all, and this page will not suggest otherwise.
Best for: A low-value approach already covered by a real camera elsewhere, where a second housing costs nine euros instead of ninety.
Four dome shells · red blinking LED · four warning stickers · records nothing
Four dome shells with red blinking LEDs and, more usefully, four warning stickers. DODUOS states wall, ceiling or door mounting; none of the four contains a camera.
Best for: A larger property or a small business frontage where several corners need marking cheaply.
