Know the moment someone walks in. From 500 feet away.
The Trevo Sensors wireless motion detection system alerts you instantly when movement is detected — at your front door, your driveway, your stockroom, or anywhere you need eyes when you can't be there.

Choose from 58 ringtones, set 1 of 5 volume levels, and expand up to 20 sensors per receiver as needed.
No wiring. No subscriptions. No WiFi required. Just batteries, a wall outlet, and instant peace of mind.

I put the sensor on my detached garage door and the receiver in my kitchen — about 150 feet apart with two walls in between. Works flawlessly every single time. I know within a second when someone walks up to the garage. Setup took 3 minutes. Ordered 2 more sensors for the back gate and driveway.

I bought this for my small boutique. It chimes when customers come in so I don't have to stand at the front all day. I set it to a soft doorbell tone at medium volume — professional and subtle. The 58 ringtone options were way more than I expected. It's exactly what I needed without any complicated camera system.

Works great as a driveway alert. Picks up cars and people reliably. The alarm on maximum volume is seriously loud — 110 dB is no joke. Only reason for 4 stars: the sensor batteries last about 3–4 months with regular triggers, so you'll want spare AAAs on hand. But for the price and simplicity, it's hard to beat.

I'm a caregiver for my elderly mother and this gives me peace of mind when she gets up at night. I put a sensor outside her bedroom door and the receiver by my bed. When she gets up I hear a gentle chime and can check on her. No cameras, no complicated apps — just a simple alert. She doesn't even know it's there. Exactly what I was looking for.

Frequently Asked Questions
Does it need WiFi or an app?
No. The system is completely standalone — no WiFi, no app, no smartphone required, and no monthly subscription. The sensor communicates directly with the receiver over radio frequency. Plug it in and it works.
Does the signal go through walls?
Yes. The 500-foot range works through standard walls, doors, and floors. In most homes and businesses, you'll have no issue placing the sensor outside and the receiver anywhere inside.
Will it detect animals or pets?
The PIR sensor detects body heat and movement, so it can be triggered by larger pets or animals walking directly in front of it. Mounting the sensor higher (about 6 feet) and angling it slightly downward helps reduce false triggers from smaller animals.
How many sensors can I add?
Each receiver supports up to 20 sensors, and you can mix and match as many transmitters and receivers as you need. Start with one sensor and expand over time as you identify more zones to cover.
How long do the sensor batteries last?
The sensor runs on 2 AAA batteries (included). Battery life depends on how frequently it's triggered — in a typical home setup, expect 3–6 months before needing to swap batteries. The receiver plugs into a wall outlet, so it's always powered.
How do I change the ringtone?
Press the volume or down button on the receiver to browse tones. Hold the volume button for 5 seconds (or press volume + down briefly) until the receiver dings and the LED flashes. Then wave your hand in front of the sensor to confirm the new ringtone. Takes about 10 seconds.
Can I use it outdoors?
The sensor can be mounted outdoors in a sheltered location (under an eave, porch, or overhang). Avoid direct exposure to heavy rain or extreme weather. The receiver should stay indoors plugged into an outlet.
Can I assign different tones to different sensors?
Yes — each sensor can be paired with a unique ringtone on the receiver. That way you know which zone was triggered just by the sound. Front door gets a doorbell chime, back gate gets an alarm tone, etc.
What's your return policy?
30-day money-back guarantee, no questions asked. If it doesn't work for your setup, reach out and we'll take care of it.
