Dormitory party's simple security device experience (out of the box + video)
As a hostel party, how did I think of buying a security device?
One morning last month, I struggled to get up and go to work I didn’t find the pants that I took off on my chair last night.
. At this time, I shook my roommate. "Did you take my pants...
(Just the logic of God), roommate opened his eyes: "You are crazy! ! â€
I saw it again. Hey, I didn't have the bag on the table! Thief! !
2. How do you see? Which one? Due to the company dormitories that lived, naturally, there was no money to seal the balcony to install anti-theft windows. The thief climbed up from the balcony and even stole 3 (I could live on the 3rd floor! )
When summer comes, the 40-degree Yunnan (four seasons like spring) says that if you close the window, my roommate will be steamed...
However, if he comes back, my kidney 6 and aliens are swollen! !
————————The picker is based on the above conditions————————
According to the above conditions began to pick security, first pick this kind of:
Infrared grating, on both sides of the cast more than one infrared beam, if there is a beam block, alarm. Perfectly meets all the conditions I want.
A look at the price: 200~300 This is not finished yet. We have to add a host to use it. The host computer is the cheapest. It's more than 200...
Then found this: curtain infrared sensor wireless detector! It works like this, stealing the seller's map:
Projecting a curtain-type infrared in a region, if live objects pass by, oh!
The key point is that you don't need to use a host or an alarm, you can use it alone and alarm, and the key point is that the price of 50+ will be paid directly.
In order to avoid advertising suspicion, I will not let me pick up the link, and there are many sellers of such devices, the richest man found a search.
3, out of the box (bao)The courier arrived just this afternoon and actually received two couriers. One was the alarm and the other was the last.
I picked one of the extraterrestrial stars to be a little bitter (tian) ran 力 ( ( , , , , , , , , , , , , , , , , , , , , , , , , , , , , ,.
Unpacking!
A total of these things: instructions, host, remote control, battery, screws, double-sided adhesive.
It's really easy to get started. It's a bit different from the imagination. The plastic shell feels crunchy... However, at this price, we have to take a bicycle.
Here is a small mouth, in addition to the battery, you can also use an external power supply (searched for the box, no power cord ... ... the seller said to buy another Good pit). I will use the seller’s battery first.
The milky white below is the part of the infrared projection.
The angle of this thing can be adjusted by itself and can adapt to a variety of circumstances. This is not a good shot, I will once again steal the seller's map:
The screw that can be used when installing, can also use double-sided adhesive (very light, can stick steady): Physical map that I install:
Mounted on the balcony sliding door top. (Consciously ignores the ribs)
The following is a video scene test that has been tested several times and is very sensitive. Even if you walk from the side, you will be alerted. The voice is also very loud, no longer need to worry about the thief coming in and putting my trousers out. I don’t know yet.
This is a remote control, slightly wider than the U disk. The circle above is the "start protection". When pressed, the detector will ring three times. After 15 seconds, the protection will be turned on.
Once someone breaks in, alarm 30s. The first "Unlock Pattern" below is "Stop Alarm, Stop Protection". Get up in the morning to cancel the protection.
The second lightning pattern below is an emergency help button. Whether your machine is on or off, pressing this one will start the alarm. It may be an intimidating effect on the thief.
The bottom one is the "doorbell mode." Someone passing by will "click" and "owner mode"?
5, use experienceNo thief has ever entered, but with roommates for many simulations, the police can be very sensitive. But the curtains drifted without alarm, and I didn't know how this was done.
Workmanship, detection of the host, plastic, and workmanship are a little rough, but this price is also worth the function.
If you want to change the battery of the remote control, you must use a screw to open the back cover to change it.
In general, more than 50 pieces of alarms, dormitory party, enough. If it is your own home, it is worthwhile for you to invest more in safety and choose more advanced equipment.
6. Chatting Say back to the above package. Actually received two parcels, one is a pickpocket, the other is?
Hey, a roll of toilet paper and a small cloth bag, what? Friends of the basic gift?
This... who sent it? ! You are thick!
