Solar Motion Siren + Strobe (110dB)
A solar-charged motion siren with a red strobe, for the shed, the side gate and the corners of the yard where no outlet reaches.
- Sound and light, right where they walkA PIR sensor on the front reacts to a warm body moving across it. When it does, the 110 dB siren sounds and the red strobe flashes at that spot. The person at the shed door knows they've been noticed, and so does anyone in earshot.
- Charged by the sun, not an outletThe panel on top charges it during the day, so it goes where there's no power: a shed wall, a fence post, the far side of a detached garage. No extension cord, no electrician. There's also a 5V charge port on the back.
- Four modes, one buttonSound and strobe all day, strobe only all day, sound and strobe at night, or strobe only at night. Press the button on the back to step through them. The full siren suits the shed out back. The quiet strobe suits a spot near a neighbor's window.
- Hangs on a wall or a postA metal bracket with two keyhole slots sits on the back, and the screws come in the box. It's 120 mm tall and 69 mm wide, small enough for a fence post, in a waterproof case made to live outside.
Why the far corners get skipped
The places with no outlet are the places with nothing on them.
Most outdoor security starts at an outlet. Cameras want power and a signal. Floodlights want wiring. So the front door gets covered, and the shed at the back of the lot, the side gate, the detached garage and the fence line stay dark and quiet. Nobody decided to leave them open. There was just no plug out there.
This one doesn't need a plug. The solar panel on top charges it by day. The sensor on the front watches for a warm body moving across it. When it sees one, the siren sounds and the red strobe flashes at the spot itself, so the person who walked up to the shed door is standing in noise and light. The warning happens where they are, not on a screen somewhere else.
Two limits are worth knowing before you order. It doesn't record anything. It makes the spot loud and bright, and that's the job. And a motion sensor can't tell a person from a deer, so where you point it matters. Aim it across the path to the door, not over open lawn, and pick a night-only mode if the yard is busy all day.
Nobody decided to leave the shed open. There was just no plug out there.
Loud where it helps. Quiet where it wouldn't.
A siren is the right answer at the shed at the back of the lot, and the wrong one under a neighbor's bedroom window at 11pm. That's why the modes matter. Two run all day and two run only at night, and each pair has one with sound and one with the strobe alone.
Press the button on the back until you reach the mode you want. Full siren and strobe for the detached garage. Strobe only by the side gate, where a flashing red light says the same thing more quietly. Night only if the kids and the dog have the yard all day.
On the wall in a few minutes
Pick a spot with sun
The panel on top charges it, so choose a wall or post that gets daylight. Face the front across the path someone would walk: toward the shed door, the gate or the side of the garage.
Hang it on two screws
Drive the screws from the box into the wall or post, spaced to match the two keyhole slots on the metal bracket, and hang the siren on them.
Choose a mode
Press the button on the back to step through the four modes: sound and strobe all day, strobe only all day, sound and strobe at night, strobe only at night.
Walk past it
Walk across the path it's watching. It should sound or flash. If it catches too much, like the street or a neighbor's yard, angle it down and across your own path.
The shed, the side gate, the garage out back
Anywhere outside that holds something worth taking and has no outlet nearby. The garden shed with the mower and the tools. The side of the house where the trash cans live and the gate doesn't latch well. A detached garage. The fence line of a big lot. Put it where someone would have to walk to reach the thing, high enough that the panel sees sun, and that spot stops being the quiet one.
The siren covers the yard. The alarm covers the glass.
Out back, this one fires when someone walks up. The house itself needs its own layer at the windows. The TremShield Vibration Alarm sticks to the glass and fires 125dB the moment someone pries or knocks on the pane, before they're through it. Most homes have more than one pane worth covering, which is why the 6-pack comes to $99 for 6, $16.50 each.
