My house didn't have a door bell when I moved in, and people just knocked. That seemed OK, until recently when I had repeated failed delivery attempts. After I'd installed a surveillance camera, it showed that, rather to my surprise, on the most recent failure, the guy had actually come to the door. Presumably, he knocked, but not loud enough.
So I installed a door bell. Tested it. It worked fine.
Then the very first time a delivery guy used it, it jammed in the on position. Apparently, the bell push wasn't designed with delivery drivers in mind.
Yeah, I had two packages sent via DHL on the 23rd, one from the USA and the other from Singapore. They both arrived in Melbourne within the week, the Singapore one a day or two earlier as you'd expect. On Monday I picked up the USA one at the post office, still waiting on the Singapore one. You can't apply logic to these things.
But DHL use Aus Post for the delivery within Australia, the courier services used by RS and e14 don't (for me).
not quite, they are delaying their vans picking up parcels from online retailers in syd/melb only, until they clear a massive backlog. In Brisbane, I just got a parcel from WA in 3 days, so no go slow there :)
I have a wireless doorbell with the push-button on the door flame. Nevertheless, most knock on the door instead. I guess they just don't see it.
BTW
there have been four occasions where a recording camera covering my door at a previous address would have been invaluable. On one such it would have avoided my being falsely charged with a crime. Recommended.
**SNAP! Same here. I wouldn't "most", but I reckon 50% still knock on the door, despite the faux antique finish Ring doorbell button, which has this neat illuminated ring around the button. It is impossible to miss. Yet they still knock.
**OUCH! I am chuffed with the Ring doorbell. Before I purchased it, I consulted a guy who spends his working days installing professional video intercoms (stuff that costs between $2k ~ $10k+). He told me that he had installed a few Ring devices and found them to work flawlessly.
I might have to design a knock detector. Obvious issues are responding to other noises, and in particular responding to the door being opened and closed.
** A crazy situation exists for many people living in strata blocks: Most such blocks have an external door bell and intercom system. Inside each unit is a pretty loud sounder that residents soon get to accustomed treating as their door alarm. Unique sound, nothing else like it, audible in each room. Hearing it will get you out of bed in the morning, to see who the heck it is.
But one or two mornings each year, the "fire safety inspector" arrives. They do not use the external bell system at all, cos they have a key to the main doors of the building. Instead they tap, tap on each door. Maybe at 7am.
This does not wake anyone or even remind them of anyone being at the door - since that is not the right trigger sound. In unit blocks, one hears random tapping noises all the time and learns to ignore them. So your unit gets missed by the inspector and you cop a letter from strata with a nasty threat of a $2000 or more fine.
To avoid such NON EXISTENT fine you are to arrange a call back and pay a cash fee of $150 or more.
This nonsense is entirely as intended by the inspection company. Backed up by assholes in strata management.
You can buy knock sensors, they might work on doors :) or build something, eg: a normally closed leaf switch with one leaf soldered to nail in the door and the other soldered to a weight
Door slamming could be perhaps cured by a reed switch with a timeout
Perhaps a fast reed switch and a slow one in series, (a slow reed switch is a regular reed switch inside a copper block)
