12v sensor Customers Reviews

  • Nice product, with not very good documentation.

    posted by hpopov

    + Everything that you need is in package+ Compact and easy to be mounted, if you have good documentation (see cons)+ Works fine almost all the time.+ Intuitive and simple use, after installation.
    - Can have better documentation, but still in YouTube you can found a superb movie with whole process, just search for "Parking sensors fitted. No drilling required. Invisible from outside"
    - Good value to performance ration, some improvement on documentation is needed
  • Unbelievable low price for top product!

    Very well constructed and very versatile product. Due to the multiturn potentiometers you can set sensivity and time very acuratly. LED gives you indication of the relay state wich makes adjusting to your needs very easy. When LDR detects light the relay will be activated and released when it gets dark. The time is actually the delay before the relay is deactivated. So time is actually the hysteresis.
    The relay on the board makes this useable for almost any project!
    This is a wonderfull product for an amazing price. If you would buy all parts seperatly it would cost you more.
  • Cheap and useful

    - Cheap- Easy to install. 1 hour + 1 beer and.. voilà, enjoy it.- It works quite good- No adjustment / configuration needed
    Nothing to say It´s a cheap and very useful accessory for parking your car, you will not be disappointed.
    Overall is a good product - cheap and efficient. Highly reccommend to anyone that wants this type of back-up distance warning device.
  • 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.
  • A good sensor

    Sensitive enough. Not expensive. Powered by a large distance. A switch inside the sensor sensitivity. Instruction in English. Built-in relays for signal control signaling. The passport is the radiation pattern of 12 meters. Enough for a large room.
    Good inexpensive motion sensor. Adapted for the alarm system on the perimeter. Long range, excellent sensitivity. False positives are not watching.
    Can be taken.
