Welcome to c/news! Please read the Hexbear Code of Conduct and remember... we're all comrades here.
Rules:
-- PLEASE KEEP POST TITLES INFORMATIVE --
-- Overly editorialized titles, particularly if they link to opinion pieces, may get your post removed. --
-- All posts must include a link to their source. Screenshots are fine IF you include the link in the post body. --
-- If you are citing a twitter post as news please include not just the twitter.com in your links but also nitter.net (or another Nitter instance). There is also a Firefox extension that can redirect Twitter links to a Nitter instance: https://addons.mozilla.org/en-US/firefox/addon/libredirect/ or archive them as you would any other reactionary source using e.g. https://archive.today . Twitter screenshots still need to be sourced or they will be removed --
-- Mass tagging comm moderators across multiple posts like a broken markov chain bot will result in a comm ban--
-- Repeated consecutive posting of reactionary sources, fake news, misleading / outdated news, false alarms over ghoul deaths, and/or shitposts will result in a comm ban.--
-- Neglecting to use content warnings or NSFW when dealing with disturbing content will be removed until in compliance. Users who are consecutively reported due to failing to use content warnings or NSFW tags when commenting on or posting disturbing content will result in the user being banned. --
-- Using April 1st as an excuse to post fake headlines, like the resurrection of Kissinger while he is still fortunately dead, will result in the poster being thrown in the gamer gulag and be sentenced to play and beat trashy mobile games like 'Raid: Shadow Legends' in order to be rehabilitated back into general society. --

Any given shelf is generally visible by like 6-8 cameras.
Oh, I see. That's fucked. Over here stores have like...3 cameras total? Giver or take? Positioned in a way that multiple aisles are covered by a single camera. We don't really have a lot of fearmongering about shoplifting though.
It's not really about shoplifting, the cameras are a core component of the system, and if they could use fewer they would. Say what you will about the concept, but the cameras themselves aren't really the insidious part, in my opinion.
I'm assuming these cameras all have to be wired, right? If they were wifi, a concentrated deauth attack could take the whole store down.
Yeah they're wired, larger grocery stores were kind of a problem because they need up to like 10gbps connection, which is pretty abnormal for a grocery store. Because yes, almost all of the video is processed in the cloud, although they are trying to shift more of it to processing on devices in the stores.
