Nice..now I finally understood..bought one but the manual is in chinese..I only got two questions..do I use the usually close terminal? And how do I connect an alarm ? Thanks
You repeat the same things a lot but the reason I came here, is only touched very minor. Which version should I buy as in detection lenth. Should I buy a 30 meter version if I have to cover 30 meters or can I better buy a 120 meter version for 30 meter? The stronger the better? or not?
As long as the detection length specification is rated for outdoors then its fine. Some give specification of indoors which is higher. If your distance is 30m and the beam max is 30m for outdoor this is a question of quality. Since there are many companies who make this, i can only comment on the ones i have used and if you install 30m its fine. To be on safe side get 60m ones if you install over 30m. But no you don't need to get 120m for 30 meter distance. Here is an install ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-U9N5ho-L3mM.html
Hi sir.. Your video is very informative. I would like to get a suggestion, between PIR or Laser beam sensor which should I choose for residential security purposes ?
there is no best single option for a whole house system. The point of alarms is to detect intrusion. Since intruders try different ways of getting in (crawl, walk, jump, slow walk, masking), the best is to use multiple systems. So to answer your question, if you can use more than one method is better than one alone. Beam is good if the intruder cannot see the sender and receiver. PIR is good as it covers wider spread. I first do PIR, then i add beams to increase security.
I need these to cover a distance of around 7m however ive read that exposing them to direct sunlight can trip them. Further reading suggests you have to "out power" the sun light hitting the receiver. Do you if the difference between the 60m outdoor range and one say with a 180m outdoor range is a more powerful ir emitter? Do you think the longer range one at a short distance will be powerful enough to "out power" the sun light entering the receiver? Thanks
