    I bet a lot of you belong to the "HVAC crapped out at the worst time" club.

    I grew up in one of the hottest parts of Los Angeles. Until 1973, we had swamp coolers that maybe brought the temperature down to the 80s. When I was a kid, we didn't really notice, You don't sweat when you only weigh 60 pounds or so, and there wasn't a lot of A/C around, certainly not in the...

    BYOB - Build Your Own Beijing | Crazy, game-changing things you can do with latest AI

    I took a little time to see what Qwen does. Wow. Unbelievable. Here's a general video: , Apparently it's good at OCR. So instead of trying to extract a license plate from three or four frame grabs from a four second video, as BI/Codeproject AI is doing, Qwen can look at every frame. It...

    BYOB - Build Your Own Beijing | Crazy, game-changing things you can do with latest AI

    One thing I love about algertc's alpr database is that I can run it, Blue Iris and Codeproject AI all on a very low power pc, though I may have to add a gpu. I wonder how much bloat would be involved in making the analysis more powerful?

    A little digging suggests some methods: Levenshtein distance Description: This algorithm calculates the minimum number of single-character edits (insertions, deletions, substitutions) required to change one string into another. You can set a threshold to determine if two license plates are...

    BYOB - Build Your Own Beijing | Crazy, game-changing things you can do with latest AI

    I'd like to send the computer through the database to clean up misread plates. Things like Bxxxnnn which should be 8xxxnnn. This should be easy for ai given that a common pattern for recent plates is (7, 8 or 9) xxx(letters) nnn (numbers). Also, if it saw 10 reads of a plate, say 8xxxnnn...

    Unshielded CAT5 cable in EMT conduit outside?

    If you have time, haunt the government liquidation sites. They almost give it away, but I don't see it that often within a driveable radius. If you don't need a whole reel, look on Craigslist. Some guy who bought 1000 feet has 700 left he wants to get rid of. There's always a few of those...

    What could be the role of old-school motion-detector lights in the security camera world?

    Your neighbors will hate you if the wind makes your lights flash on and off all night.

    Firmware update – if to do, and how

    There are a lot of horror stories about cameras losing features etc. and plain old bricked cameras with updated firmware. Consensus says don't update without a good reason. I'd trust an Andy update over a factory update, as he is responsive in a way Dahua isn't. Also, search the update in the...

    Unshielded CAT5 cable in EMT conduit outside?

    Also, use Cat6 or better. Even if some corrosion starts, it will take longer to disrupt the signal with thicker wires than with wimpy cat 5.

    Algertc ALPR database and VPNs

    Just a post mortem comment to help anyone in the same boat. When I ran the first command: psql -d postgres -U postgres -f /docker-entrypoint-initdb.d/schema.sql I got a bunch of messages telling me that a bunch of files were already there. When I ran the second command: psql -d postgres -U...
