synaesthesia

With some luck, they've updated and fixed them It still seems odd that they'd deviate away from the UI's used on other devices; simply enough to do even with differing operating systems, but when nomenclatures differ it gets confusing. From what I remember, it was the PVID and native vlan settings which were really odd!

Decent quality and performance; absolutely diabolical UI! The VLAN configuration is enough to make you give up IT, relocate to nepal and live as a goat.

I quite enjoy the senior tournaments, because there's some proper humans involved. People with personalities, people who enjoy a laugh and don't take it too seriously. I have all the time in the world for the likes of Jimmy White, Dennis Taylor, Ken Doherty, Mark Williams et al. Have played Shaun Murphy a few times, although granted we were both in our very early teens! (Yes, I was thoroughly spanked!)

Looking at the design of the sensor posted above, if they're now also using fans that will falsely keep heavier particulates in the air for longer which seems counter intuitive. Vapour doesn't need to be drawn in, it's just there.

Right, I've reported my original posts for deletion as I've had an email from SMF Systems/Vapeguardian keen to answer some concerns. No data is sent to China. All data is apparently kept in the UK, with some anonymous & encrypted air readings do go via the Tuya API. They confirm the boards are manufactured in China by Airbath. He states they are designed in the UK, however from my own contact with AirBath this actually means they specify what they want here and Airbath make them to order (which they will do for anyone with suitably sized orders). I don't want to vilify anyone but as I've told them, I have a huge bee in my bonnet about misinformation and I'm keen to kick it out where I can. Marketing is just another word for bovine poop, so there will always be a bit of leeway there but that's another story. I've given some feedback regarding false positives and domains/cross website functionality not being there, and I don't know if their app is now available on the App stores yet. Again, personally if an app isn't on the Google play store or Apple store, then it's not yet trustable. Testpilot isn't meant for any sort of deployment outside testing, and the less said about random APK's the better. I have suggested transparency - liaising with their actual customer base outside of marketing and the newspaper articles they've been mentioned in (https://www.thetimes.co.uk/article/vaping-is-causing-chaos-in-school-loos-can-this-gadget-fix-it-6rs7wvn3n and https://www.dailymail.co.uk/health/article-11891095/How-purposely-installed-vape-detectors-set-22-TIMES-day-schools.html ) will be a lot better for them. They are apparently working with Southampton University regarding getting the formulas right for detection which sounds interesting. I'd love to see some information regarding this, case studies etc.

Reading them is of little importance. Accepting them however, is. (Whether that stands up in court, disciplinary hearing, expulsion hearing etc is something else though!)

A very wise idea @Ditto - Arbor have already shown willingness to communicate and listen, and that could certainly help prioritise areas that they perhaps may not view as important as a school.

"I'd like to buy this Ford please?" "Are you sure? Vauxhall's legal team would like a word...." (sorry, couldn't resist)

Depends when you bought/ordered them - I think we got lucky as they were recent orders, just prior to being announced EOL. Either that or our trust procurement team are miracle workers. And yeah, our MAC's are the same. They are reporting twin MAC addresses though at points on our dhcp server. It may also be a larger combination of hardware. The other mac's pick up as B8:27:EB. They're certainly intriguing devices and keen to know more about how they work - compared to the chinesium devices we have, there appears to be a lot going on.

As I put in my original post, I imagine it will be a combination of the sensors and the software doing the grunt. I wouldn't mind knowing what's in the Halo sensors for their prices. We tested a chinesium device based on an "Air Bath®" with a senseair.com detector and "WBR3" combi bluetooth & wifi. Parts that literally cost £8 and the "UK Company" shifting them are charging 10 times that. They're in generic plastic boxes which would otherwise house ethernet switches, routers, usb hubs and connect with those awful home smart apps. It's not always technical too - you need to think legally. Let's say you exclude a student where part of the evidence is as a result of one of these devices. With 2 of the big names, you'll have support should you need it in a review hearing. Will not be that easy otherwise, it could be made entirely inadmissable.

For the verkadas? Not a chance. As said above, it's way more than just a VOC sensor, because that alone isn't sufficient for reliable vape detection.

Yes. Take the stolen remotes off the students that have them!

Indeed, and soon I think the clicky clacky yellow/red handled ones which I'm suprised I've yet to find dotted around the nuclear wastelands in the Fallout series intact, as testament to their build quality.

Unsure on the cameras, we've only got 6 sensors in (SV11) working alongside our existing CCTV. I haven't had the SV11's apart but they picked up on DHCP and their mac addresses show they are RPi3 based. I can't go into costing specifics but ours were WAY less than £510 a unit. Worth asking around, there's quite a few resellers of the gear in the UK.

Indeed, there's a small scope for this to work reliably - so if there's more than 2 cubicles, you'll need another sensor. Make sure they're synced with the same time server - we don't have any issues with timing.

Verkada are Raspberry Pi based but VERY much worth the money. The SV11 are on sale at the moment - they're not as expensive as you think. It's pretty much the software you're paying for, but the hardware is very well built and runs on PoE. Halo is the other name worth looking at. Do not get sucked in by fly by nights like SMF Systems who are flogging chinese whiteboxes worth £18 for 10 times their worth, using consumer grade "smart device" software to manage. Verkada at least has PM2.5 and TVOC separate from vape detection so false positives are mitigated, plus with motion and noise detection it makes it worth while. Addition: Hopefully this helps show the difference a little - here's the difference between the PM2.5 detection and specific Vape detection for the same sensors, so you can see the distinct correlation. You'll be able to do it with just PM2.5 but expect the vape is a mixture of that and the air quality index. TVOC doesn't flag for vape. This is the Vape index: And the PM2.5: And air quality: Looking at pm2.5 alone, you will be getting constant false positives from female scents - perfumes far more than male deodorant trigger this highly.

I'll give you that - specifically the 7800 controller Had them for my Atari 800. Ergonomics that would make Razer proud.

Been a while...

Individually for me, although only have 5 of them for a large primary. Don't think there's anything but there are MIB files available so no doubt some third party stuff should do it. Not sure what's available these days, HP's Procurve Manager used to be able to use MIB files to manage 3rd party switches.

Indeed - I can't see the point myself, our repro team lodged a call with Konica believing our devices to be faulty going through toner so quick.

Anyone else still having ongoing issues? We're now being sent half-full toners (model numbers have H on the end to signify this) due to demand. Surely that can't be right?

Although Dynabook's support/after sales has been good to my infant school, out of 6 devices supplied last year, we're on our 4th failure. Same model as above.

Any half sensible people will reject this daft idea. Do those camps also use Windows to administer? Ban Microsoft products from school. Do they search with Google? Same applies. Do Hikvision run those camps? Why are they being targetted for this oddly far fetched reasoning?

Any ONVIF compatible camera will work - we have or have had brickcom, unifi and AXIS on them without issue.

They won't be able to put a ban on use, that's more than clear. I don't think the cameras themselves are likely to be an issue - there's very little that are better options, and I don't think anyone would lament the loss of the NVR's in favour of better NVR/storage solutions - most of which will handle all the features the HV NVRs do.
