Haven't installed it yet

looks like the DS Electric Eye detection system I've installed for years. When setting up the electric eye, bring a flashlight and chair with you to calibrate it. You don't need a second person if you place a chair directly in front of your eyes and have a lantern on the chair facing the other end.

Pros
  • Application: Ideal for installing in a security system in a school, office building, hospital, home yard, etc.
Cons
  • Protection

Works as described

The product is quickly assembled after carefully studying the instructions. The person who wrote the instructions lacked basic English skills, but after some introspection I was able to decipher the intent of the installation guide.

Pros
  • Reliable and safe: Yohii's double infrared laser alarm provides strong environmental protection and minimizes false alarms from falling leaves, birds, etc. etc.
Cons
  • Small things

The Best Limiting Beams for Your $$$

Two of them have been working on our territory for more than a year. They are outdoors in the rain and hot weather. You need to know what you're doing to set up a true perimeter system. This product gives you the ability to have a folding system simply by adding a ground release. I asked the local sheriff's department to confirm how well built it was. I've used many other $200-$800 systems that have failed. I built them as a standalone perimeter system with a rear battery for less than $180…

Pros
  • Powerful Feature: Real-time hologram spot reporting. Unique high power biased transceivers. Full functional test, self-adaptation to the environment and troubleshooting.
Cons
  • Difficult to say

Set up your IR beam - run 2 wires to the UT switch and set the switch to point towards the house or location where you wish to install the receiver. connect to the dakota receiver and assign an audio signal - done. I use this beam IR sensor on the entire front line of the site (100 feet) and use the dakota dcmt-4000 PIR for an open area at a 90 degree angle from the breakout beam sensors. My only criticism is…

Pros
  • Durability: Powerful auto-adjustment design. The transmission power is automatically adjusted according to the environment, which significantly extends the life of the launch tube while reducing power consumption.
Cons
  • Clarity
