Review: Works well and not that hard to set up. - This review is for a "Dahszhi Dual Laser Detector Alarm Beam Sensor Indoor 300m Outdoor 60m Infrared Detector" This is a reliable alarm that doesn't give false trips and its not tripped by cats, dogs etc. (unless they are over 3 feet tall). The internal NC/NO switch is rated at only a few milliamps so you'll burn it if you try to drive a load directly. A few basic components have to be added for a complete circuit. A relay, transistor or triac, alarm buzzer or equivalent (depending on application) and a power supply at both ends. My installation has the receiver and transmitter about 60 feet apart. The setup isn't hard and tools are provided to simplify it. A small mirror assembly helps with aiming and a signal strength test point (VDC) makes it so you can tell when the beams are properly aligned. The most involved part is running wires. === Update: Had one of these running almost a year now, 24/7 with no problems. I bought a second set that establishes a beam across the entire width of our front yard and rings a door bell. Visitors don't have to press a doorbell button because they trip this beam and it does the same thing. And anyone approaching the carport trips it as well. These units are well sealed from weather and I've found them to be very reliable. I was using one with a 12V 30 milliamp relay coil for a while, but that may be pushing the operational limits so I added a simple transistor circuit to reduce the current through the normally open contacts to about 4 milliamps. A cat was able to trip the doorbell by jumping off the car hood -- through the laser beam, but aside from that, no false alarms. :) I don't see any issue about how well these units are constructed. They are built well for the application. The entire electronics assembly is easy to completely remove from the housing for maintenance if it ever becomes necessary. Very good product.
Review: Indoor :excellence prorformance - Installed 40 of this puppies. They have no issue with distance. 4 of them shoot through a cut out in a wall halph way from the receiver. They work as advertised. Each shot was 260 to 310 feet.

## Features

- Reliable & Safe: Yohii laser alarm with twin infrared beams provide reliable perimeter security, minimizing false alarms from falling leaves, birds, etc. Lensed optics reinforces beam strength & provides excellent immunity to false alarms due to rain, snow, mist, etc.
- Principle: This is Alarm Two Beam photoelectric infrared detector ABT: 60m. Install them at the opposite positions. Then there is a infrared area between these two detector parts. When someone passes the infrared region for an adjusted response time, the detector will send alarm signal to the security alarm host (which not included here) work with 2pcs power apater
- Powerful Function: Holographic spot real:time report. Unique displacing receiving, transmitting parts with big power. Full function checking, self:adaption in environment and trouble locking
- Durable: Powerful Automatic Adjustment Design:The transmit power will be adjusted automatically according to the environmental conditions, which greatly extends the life of the launching tube, while lowering power consumption
- Scope of Application: Great to be installed for security system in school, office building, hospital, home yard, etc.

## Questions & Answers

**Q: Does this make a noise when the beam is broken ?**
A: No.  You must use a relay to power a siren or strobe.   All the beam sensors operate this way.   You have open or closed contacts.   I use 4 of these sensors connected to a niles ipc6 intelligent power controller to turn on an electric fence, a 135 db siren, strobe lights, a laser show and multiple light beams.   All trigger on in a programmed on and off sequence when the beam is tripped.

**Q: Minimum Spacing between sensors?**
A: 6 ft was the shortest distance I achieved

**Q: What is the signal output when a person is detected?**
A: Good day,this item the signal output when a person is detected is 100 meter

**Q: Are they just IR sensors,  what are power supply they need ?**
A: Need 12v power supply,have a Positive and negative

### ⭐⭐⭐⭐ They work well--- Eventually
*by L***Y on June 11, 2025*

After I finally got it working it performs well. Instructions are a clear detriment. The alignment mirror device is not clearly explained, and in the end, a useless component. Just align the two unit by eyeball and use a voltmeter to confirm sufficient accuracy. I needed these to alert intrusions by javelinas, coyotes, and donkeys in my Arizona back yard. They are positioned about 100 ft apart and operate correctly. However, I had setup the trial in my garage, about 10 ft apart. Here, I could never get them to function consistently. After hours of messing with settings and connections, I realized that the lenses needed considerable dampening. The darkly tinted housings accomplish this, which became apparent after I covered one pair of lenses with masking tape. I had put the masking tape there so that I could use a laser to assist with alignment. To my surprise, that is when they started to function as desired. I never considered putting the housings on in the trial setup, since I was still dealing with wiring issues and internal adjustment mechanisms. Hard to do with covers installed. Again, this could have been mentioned in the instructions. Seems that not everyone is as persistent as me and simply return them to Amazon out of frustration.
