Pet immunity is a stated weight limit, and it is measured at floor level · review
Four sensors and a plug-in chime for thirty-five dollars — on the only listing here that publishes no detection range at all.
The conclusion Four sensors onto one plug-in chime for thirty-five dollars is the largest set on this shelf, and the 15 to 30 second re-arm delay is a real feature that stops a busy doorway chiming continuously. But the page never says how far a sensor sees — the 328 feet in the title is the radio link to the receiver — and no other listing here leaves that out. It is also explicitly not waterproof, on a product called a driveway alarm.
NO DETECTION RANGE. No field of view. No pet immunity.
Not the sensing.
It is how far the plug-in chime can be from the sensor. The title says Long Range Wireless Driveway Alarm, and that is the figure it means.
How far the sensor sees is published nowhere on the page.
Every other PIR on this shelf gives a number: sixteen to twenty-six feet, twenty-three, thirty, thirty-two, forty.
Assume the same class of device — somewhere around twenty to thirty feet — and get it from the seller before trusting it on a drive.
Which the listing says itself.
Not waterproof. Keep away from rain or cover adequately.
A porch, a carport, under a soffit, inside a closed garage: fine. A gatepost in the open: not through a winter.
And mounting it indoors pointing out is not the workaround — another listing on this shelf states plainly that a PIR cannot detect through glass.
Which is the real feature, and the only one of its kind here.
Without a re-arm delay, every crossing chimes. A delivery driver walking back and forth to a van produces a dozen chimes in a minute.
Fifteen to thirty seconds means one chime, then silence until it expires.
The two 125 dB sirens on this shelf publish a siren duration instead — how long it sounds, not how long before it sounds again.
Three per sensor, four sensors, none supplied.
The receiver plugs in, so the chime needs nothing.
Buy the cells with it.
On sale at around $35 on the American Amazon store at the time of checking.

| Supplied | Four sensors and one receiver, stated, with the receiver able to pair with multiple sensors and the sensors installable on different floors or rooms. It is the largest set on this shelf: the next is two sensors and a receiver |
|---|---|
| Detection | NOT PUBLISHED. No detection range and no field of view appears anywhere on this listing, which is unique on this shelf — six of the seven publish a range and four publish an angle. The only distance given is the radio link |
| Range | 328 ft (100 m) between receiver and transmitter — stated, and this is a RADIO range, not a sensing range. The title reads Long Range Wireless Driveway Alarm and the figure is how far the chime can be from the sensor, not how far the sensor can see |
| Trigger | The detection time delay between alerts is configurable from 15 to 30 seconds — stated. That is the re-arm interval: a second crossing within the delay does not chime again, which stops a doorway chiming continuously while a delivery is unloaded |
| Modes | 38 ringtones with a bright LED light — stated. Volume levels are not specified on this listing |
| Power | Three AAA cells per sensor, stated NOT included — twelve cells across four sensors. The receiver plugs into a standard outlet, so only the sensors need cells |
| Mounting | Wall mountable, wire-free, stated. Named for front doors, window frames, driveways and walking paths |
| Ratings | Explicitly not waterproof: keep it away from rain or cover it adequately, stated — on a product named a driveway alarm, which is the tension on this listing |
| Pet immunity | Not published, in any form. No weight, no sensitivity setting and no mention of animals |

The listing does not say, and that is the finding. The 328 feet in the title and the first bullet is the distance between the sensor and the plug-in receiver — a radio link — and no sensing distance or field of view appears anywhere on the page. Every other PIR on this shelf publishes something: 16 to 26 feet, 23 feet, 30 feet, 32 feet, 40 feet. Treat this one as the same class of device, which means somewhere around twenty to thirty feet in practice, and get the figure from the seller before relying on it to cover a drive.
Only under cover, and the listing says so in its own third bullet: this is not waterproof, keep it away from rain or cover adequately. That sits awkwardly against the product name. A PIR in a porch, a carport, under a soffit or inside a window-less garage will work; one on a gatepost in the open will not last a winter. And the glass problem applies — another listing on this shelf states that a PIR cannot detect through windows, so mounting it indoors pointing out is not a workaround.
It stops a busy doorway becoming unbearable. Without a re-arm delay, every crossing chimes, so a delivery driver walking back and forth to a van produces a dozen chimes in a minute. Fifteen to thirty seconds means one chime, then silence until the interval expires. It is a configurable figure on this listing and it is the only re-arm interval published on this shelf — the two 125 dB sirens here publish a siren duration instead, which is a different thing: how long it sounds, not how long before it will sound again.

| Model | Price | Detection | Pet immunity |
|---|---|---|---|
| seanme Long range wireless driveway alarm, 4 sensors and 1 receiver | $35 | NOT PUBLISHED. No detection range and no field of view appears anywhere on this listing, which is unique on this shelf — six of the seven publish a range and four publish an angle. The only distance given is the radio link | Not published, in any form. No weight, no sensitivity setting and no mention of animals |
| BESTOONE MSA-21 motion sensor alarm, 2 sensors and 1 receiver | $25 | About 20 ft of infrared detection distance — stated, and stated in the SAME bullet as the 300 ft radio range and distinguished from it. That is the clearest handling of the two figures on this shelf, where three listings lead with a radio distance and one publishes no detection range at all | Not published, in any form. No weight, no sensitivity and no mention of animals |
| CPVAN CP2 Pro motion sensor alarm, 125 dB, 328 ft remote | $25 | Up to 40 ft, with best performance typically within 10–26 ft — stated, and that qualification is the most useful sentence on this shelf. A PIR's rated maximum is a laboratory figure for a warm body crossing the field; the working range is always shorter, and CPVAN is the only listing here that publishes both numbers | Not published as a weight. CPVAN states PIR sensing that helps identify human movement and reduce unwanted triggers, which is an adjective |
| eufy Security T8910021 motion sensor, 100° × 30 ft | $25 | 100° field of view up to 30 ft — stated as more than enough to secure an entire room. Thirty feet is the longest range among the app-based sensors on this shelf, and a hundred degrees is the narrowest angle published on this shelf, against the hundred and ten of the wired panel detector here and two others at a hundred and twenty | NOT published as a weight. eufy states adjustable sensitivity so that it only alerts when humans are in range rather than a playful pet dog or cat — which is a setting, not a limit. This shelf's introduction and this shelf's tag both say pet immunity is a stated weight, and only at least one of the thirteen detectors here gives 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
