Pet immunity is a stated weight limit, and it is measured at floor level · review
A standalone PIR alarm that needs no hub: 125 dB, a 120° detection field, a remote control, and a switch between doorbell mode and alarm mode. It runs on batteries or USB-C.
The conclusion The right tool for a shed or a shop doorway. It tells the room, not you.
Not everything needs a hub. A garage, a shed, a stockroom or a shop counter needs a noise when somebody walks in, and this makes one.
A chime for announcing arrivals, and a 125 dB alarm for when the place is locked. A shop or a workshop uses the first all day and the second overnight, which means the device is in use continuously rather than sitting armed and forgotten.
Tell you. There are no notifications, no log and no app. If it triggers while you are elsewhere, the sound happens and nothing is recorded. That is the defining limit of a standalone alarm and the reason it complements a system rather than replacing one.
A 120° PIR field, and the same rule as everywhere: mount it so people cross the field rather than walk directly at it. PIR sensors detect movement across their zones far more reliably than movement towards them, and a sensor facing straight down an approach is a sensor that triggers late.
Keep it off walls carrying radiators and away from direct sun through glass.
Batteries or USB-C. In a garage with an outlet, run it on the cable and forget it.
TECKNET states an 8 m (26 ft) detection range, a body that rotates through 360°, a light that flashes when triggered and three sound levels: 90, 110 and 125 dB. The remote reaches up to 100 m (328 ft) in open ground, arms, disarms and switches modes, and its SOS button sets off the alarm from a distance. The warranty is 36 months for registered users.
An outbuilding, a workshop, a shop doorway.

Because for a garage, a shed, a stockroom or a shop counter, a hub, an app and an account are all overhead for a job that needs a noise when somebody walks in. There is nothing to configure, nothing to update and nothing to subscribe to.
Announcing arrivals rather than deterring them. In a shop or a workshop, a chime when somebody crosses the doorway is genuinely useful all day; the same device switches to a 125 dB alarm when you lock up. That dual use is the reason to buy this rather than a plain alarm.
No. It has no notifications and no log. It makes a noise where it is, and if nobody is there to hear it, nothing is recorded. That is the fundamental limit of standalone devices, and it is why they belong alongside a system rather than instead of one.

4–5 m (13 to 16 ft) × 110° PIR · 110 dB · 58 melodies, 5 volumes · 20 sensors per receiver
A driveway alarm expandable to twenty sensors on one receiver, with 58 melodies and five volume levels. BITIWEND states a 4 to 5 meter (13.1 to 16.4 ft) detection range across 110 degrees.
Best for: A property with several entrances that should each announce themselves differently.
Standalone PIR · 125 dB · remote control · low-battery warning · not compatible with the CP8
A standalone PIR alarm with a remote, from a maker with a decade in detection. CPVAN states a low-battery warning that ticks periodically, and is explicit that the CP2 does not work with its Wi-Fi CP8.
Best for: A shed, garage or storeroom where the alarm should warn you before its battery dies.
Two sensors and one alarm unit · 300 ft radio to the receiver, detection about 20 ft — both published, and labeled · 38 ringtones with 3 volumes AND A SILENT LED-ONLY MODE, the only silent option on this shelf · 2 sets of mounting screws · AAA not included · not waterproof
The only detector here with a silent mode — a light and no sound — and one of the few that separates its radio range from its detection range on the same page.
Best for: A household with a sleeping baby or a shift worker, where the alert must be visible and not audible
