iray e2n v1@50hz > infiray ap13 > hikmikro le 15. Ap13 much better than LE15 for detecting animal signature. I use myself hikmicro LH15, and it's almost best unit with wide angle of view, that you can use without lens adjusting. And it rarely have normal working wifi (often there are a lot of disconnects and theare not long range of wifi range on other devices). I think, that there is no reason to buy new device with 256*192 in 2024-2025. It's much better to find device that was alredy used on secondary market.
