LOL. For me it's the height. Where I would have this my E1 Outdoor is already low enough that somebody could jump and grab it. With the 823 they probably wouldn't even need to jump.
I would love it if they eventually came out with a PTZ dome cam. Just give it a broad base to fit all the electronics, something like this, which is half the height of the 823: https://www.amazon.com/Hikvision-DS-2DE2A404IW-DE3-2-8-12MM-International-Upgrade-able/dp/B07MLJJ357
