    How Does an Infrared Alarm Sensor Work?

    • Infrared Defined: Infrared radiation is a type of electromagnetic radiation similar to visible light but with a longer wavelength. Almost everything produces infrared light. The hotter something is, the more infrared it produces. Infrared is visible to some animals, but it can not be seen by humans without special equipment such as night vision goggles
    • Infrared Detection: Most infrared cells use a Cadmium Sulfide or CdS cell to detect infrared light. CdS cells are resistors--elements that resist the flow of electricity. CdS cells are special types of resistors called photoresistors. When they are exposed to light, their resistance goes down. The CdS cell in a motion detector is set up to only detect infrared light. The circuitry inside the motion detector monitors the cell's resistance continuously and uses changes in the resistance to detect motion
    • Active Infrared: In active infrared systems, an infrared laser shoots pulses of infrared light at the CdS cell, which is attached to a detector circuit. As the pulses of light come, the resistance of the CdS cell drops, producing a spike in current. As long as the pulses of infrared light continue to produce pulses of current, the detector keeps the alarm off. If someone steps between the infrared laser and the cell, however, it breaks the beam. The current in the detector circuit then drops, triggering the alarm
    • Passive Infrared: Passive infrared sensors also work by detecting changes in infrared but in a more subtle way. A passive infrared sensor absorbs infrared in a large arc. As the sun rises and sets and the day gets warmer and colder, the infrared signature changes gradually. If a person suddenly walks past, however, the infrared from his body creates a more drastic change in the infrared being picked up by the sensor. The sensor is programmed to ignore gradual changes,but will trigger the alarm if something changes quickly

    How to Buy a Home Alarm System:

    Zrabra Ceiling Mount Wireless Infrared Detection Alarm System XY-WXHWTC

    Each year more than 2 million American homes are burglarized, according to the National Burglar and Fire Alarm Association (alarm.org). Most of them have no alarm system. Electronic security devices provide affordable peace of mind, and recognizes and reacts instantly to unauthorized entry

    • Survey your home and determine how many windows and doors you want integrated into the system
    • Contact your insurance agent, a security system adviser, the NBFAA or your police department's crime prevention department for names of security system companies. Ask each company for an inspection, a recommendation and a quote in writing
    • Decide whether you want to contract with a 24-hour central monitoring station for a monthly fee. If your system detects a break-in, it alerts security professionals to dispatch local police. Less expensive dialer accessories can link sensors to your phone lines and call preselected numbers if security is breached
    • Consider your family's lifestyle. Do people or pets sometimes roam the house at night? Select appropriate sensors and locations
    • Choose a system with a control panel that can monitor all the zones in your home. Each window or door integrated into the system is considered a zone. A basic system (about $400 without monitoring) can control eight zones, but many can be expanded to watch up to 32
    • Determine locations for the control panel and keypads. The control panel commands the system and the keypads allow you to program the system and turn it or its components on and off. A typical setup puts one keypad near the front door and another keypad--and perhaps a panic button--close to the bedrooms
    • Look for systems that connect to lighting controls, smoke and carbon monoxide sensors, and flood detectors. Also make sure system switches won't freeze in cold climates. (See How to Buy a Home Automation System.)
    • Choose a user-friendly code that everyone in the family can remember in an emergency. Try the keypad to assure that it's easy to use
    • Realize that it's difficult to retrofit a hardwired security system. With a wired system, you'll have to drill holes in walls so wires can be routed. If you want to avoid this expense and inconvenience, choose a wireless system

    • 1 x Detection Alarm

works great

We used this to know when people come in the front door when we are in the back shipping room. It works great and we can hear it even though it's in another room!

Absolutely satisfied
00:00:00 06-08-2011
I bought this item with intent to protect my home and this item works great! I have a big covered porch that wraps around my house. I keep certain items on the porch to keep them out of the weather. To protect these items from sneaky night owls. I have discretely placed the driveway alert system on my porch. The only suspects I have caught thus far is my dog and my Son who likes to always put his finger over the door peep hole so I can't tell who it is when the person knocks. Now I intercept him constantly and he is also amazed with the product after I told him how I do it.

It Really Works Well
00:00:00 06-03-2011
It is a great product, but it is in direct sun,so I need to put a cover over it,or as someone suggested,put it in a birdhouse,so the battery lasts longer.Other than that,I am very happy with it!

Ceiling Mount Infrared Detection Alarm System
00:00:00 05-31-2011
This is a great product my second one mount it about 7 inches from the ground to get a better way to catch any one walking through your yard. I rather check on a dog or cat than catch a person in our back yard. Keep it out of the sun trees when the wind blows it will do a false alarm. I will buy from this company again because every time I get one it does the job affordable to. THANKS

Happy with this product. It works well for me, letting me know if anyone enters the garage area at night. Wireless alarm unit works through multiple walls with ease.

Infrared Detection Alarm System
00:00:00 05-17-2011
I live in a town home and use the sensor pointed at my back door with receiver in my kitchen. This does not replace a security system however; it does alert me if someone is coming into the rear of my house to my basement door for peace of mind.

Ceiling Mount Infrared Detection Alarm System
00:00:00 05-05-2011
I bought this as an alarm to alert me when Granny (high fall risk, dementia, frail) gets out of bed in the middle of the night. The volume has 2 levels, both very loud. I wear earplugs at night and it still wakes me up. It's a cheap way to keep the elderly safe.
