160 degree (+- 80 degrees from the center of the moment sensor lens) and up to 12m distance.

Yes, you can use it. Frosty temperatures are not an issue at all.

It is 360 degrees and an distance up to ofop 10m (32 feet). The distance is depending of the modus. Mosquitoes modus e.g. works up to 4m and the modi for cat, marten, rat are at 10m. We work also on an free software upgrade that in future the max. distance can be set via the IRepell app to for example limit the effect an not disturb neighbours animals, … were for example an garden is smaller as 10m long and you want to keep the effect within your own space. 

No, when all modes are designed in a way that cats and dogs hearing do not get disturbed at all . But be aware of course when the no cats mode is on then of course the cat is impacted when it is entering the repellent area!

No, IRepell is designed in a way that humans including smaller kids cannot hear any sound as we are operating in and higher range of ultrasound. This is also the big difference compared to cheap gadget devices you can by at some stores. This is also an patented technology invented by the IRepell Team in Austria.

Currently the marten and cat mode is using flashlights but if wanted from the enduser they can be also turned off manually via the APP. In future more modes will be enabled for the flashlights but that depends on the outcome of our scientific work were flashlights make sense and have an impact on the repellency rate. On rats we see for example in our lab no impact at all with light vs. without.

We use an self controlled hig quality lithium ion battery pack lasting up to several days without any recharge needed as of now. With an free software upgrade during the next weeks the duration will be up to 2 months as we have redesigned the internal firmware power consumption already.
