  • very very good one

    posted by msoulforged

    - Two remotes and both have batteries inside; ready to use.
    - Unit has DC input
    - Easy to use: hit arm once (button on the remote) and green led is on. This is the exit delay, after 10 seconds the unit is armed. If it detects a motion, the red led blinks 5 times (once a second), and if disarm is not pressed it screams (really loud, it states around 105 dB)
    Very good product. Cheap and absolute alternative to very expensive alarm systems.
  • Great sensor - easy to retro fit

    This PIR does the usual 12v NC connection thing. Very well labelled connections, and very easy to retro fit into a legacy alarm system, or to build your own.
    Can be flush or corner mounted. LED inidicator can be disabled, and is above the sensor (Previous ones were below). I pulled out 4 different ones when refurbishing my alarm - nice to have them all the same!
    Great price, and a very useful sensor. Can be daisy chained in the usual way, and connects via standard 4-wire cable.
  • Good price. Dual Technology. PIR and Microwave

    posted by Nicotk

    Dual Technology. PIR and MicrowaveMicrocontrolled.The alarm is triggered when both detect. That avoids most false alarms often occur especially with sensors outside.
    Little documentation on the Internet.Documentation of similar equipment but do not exactly match.Even the Chinese user manual didn´t have several diference.
    Good product, shame the lack of documentation in English or Spanish.If one knows the subject can get by without documentation but do not get the maximum benefit.
