Infrared detector is popular motion sensor. The PIR is used for security protection of bed rooms, living room, balcony etc. It is installed with bracket for angle adjustment. The detection area may be horizontal 110 degree, thickness 65 degree of fan-shaped area.
Can you install the PIR according to the instruction manual? Below we will make clearer steps for guidance.
Step1. Using impact drill to make two holes on the wall according to PIR bracket fixing hole. Then fix PIR bracket with screws (included in the PIR package)
If there is no impact drill, using cement nail to fix the bracket on the wall.
Step2. Insert the PIR body to the universal bracket. The PIR level angle and vertical angle can be adjusted for best detection.
It is better to install PIR in the corner of wall to get best protection area. Select installation location, installation height according to PIR instruction manual. Below is the illustration of installation ways and effect.
Door magnetic contact is another essential component of home security. Door contact includes two parts: magnetic switch and emitter. When these two parts are separated by about 1cm, the emitter will send alarm signal to siren strobe or alarm control panel. Magnetic contact can be used for alarm of door windows, fence or other protected objects.
The emitter should be installed on fixed object such as the door frame. The magnetic switch should be installed on moving object such as door. If the door and the door frame is not at the same plane, you can use a small piece of wood to block up the low side.
There are metal door contact, wood door contact and rolling door contact. Please select corresponding door contact for the door security protection. You can use double faced adhesive tape to fix the door contact or use screw to fix the door contact. It is better to use screw fix it. 
The alarm system installing manual will guide how to enroll the PIR, door contact to the alarm control panel. You should read the manual carefully and follow it.

PIR Passive Infrared Detector installing notice
Passive infrared detector PIR is a type of weak signal detection equipment. There are some notices for attention when install it. For example, the installing height and sensitivity are two key points for attention. There are three steps to prepare and install a PIR detector.
Step 1: Well understand the performance characteristics of the PIR detector.
Step 2: Correctly determine the location for PIR detector installation.
Step 3: Carefully adjust and debug the infrared detector.
Below is the details for attention.
A. Installing location:
1. Determine the correct installing height and angle according to PIR installing instruction manual and using requirement, environment. The protection area, sensitivity and pet immunity effectiveness is different with different installing height. Find out the entrance and exit of the building and intrusion routine, install the detectors at places to cover the areas.
2.Do not install the PIR detector facing glass doors and windows.
PIR detector can anti interference of white light but not 100%. And outdoor passing people and vehicle may cause false alarm. PIR and MW double technology detector can be installed at this place without interference.
3. Do not install the PIR detector facing cold and hot air outlets or cold and heat sources.
PIR detector senses object’s temperature change and triggers alarm. So the air flowing from cold or heat outlet may cause false alarm. If you have to install the detector at these places, you can choose PIR and MW double technology detector.
4. Do not install the PIR detector facing a swinging object. A swing object may cause false alarm by Microwave detector as well.
B: Detector choosing and debugging
1.Correct choosing of detector.
There are various types of PIR detector. They are wide angle PIR or curtain PIR with 6m to 60m detection distance, infrared sensor or Microwave sensor, wall mounted or ceiling mounted. It should be correctly chosen according to protection space, intrusion routine characteristics, environment features.
2.Debugging
Debugging is absolutely necessary work after installing of motion sensor. There are two ways for debugging. One way is walking test. The test person walks in the protected area with S routine to check the protected area. The microwave sensor sensitivity and PIR sensor sensitivity should be adjusted separately. Sometimes the sensitivity should be adjusted again in different season. Microwave has penetrability and the sensitivity can not be set too high.
Another way is using instrument to measure. Some detector has noise voltage output interface. Using a multiple meter to measure the noise voltage and adjust the sensitivity.
Is Burglar Alarm System useless?
A survey of housing safety said burglar alarm system is useless. A good lock and scheduled house lighting is more important for home security. Is that right? Will theft pass a well locked and light house without thinking it is occupied or empty?
How can a burglar alarm system well prevent burglary and stop crime? Actually, there are many functions of burglar alarm system people doesn’t know and doesn’t use. Fox example, the linkage output function. When a burglar alarm system is triggered, it can trigger alarm siren strobe and camera recorder or house lighting. So, not timer lighting but scare lighting will be turned on to drive out the theft.
You may do not need a good lock but you can install a door windows barrier to block the burglary before they come near the entrance. Of course, the sensor can turn on the light indoor or outdoor with linkage function of alarm system.
The linkage function is a simple port built-in for easy connection with any equipment which need to be triggered. For example, the FOCUS security has this function named PGM output. The FOCUS PGM output can be programmed with some event for selection. They are alarm, password change, AC power fault, communication fault, arm, disarm. That means you can select the event to trigger siren strobe or other device. For example, you select AC power fault event, then if the AC power line is cut, it will trigger the device immediately. The selection will be made according to your alarm system installing and environment features.
When a CCTV system is connected as the event following device, the defined security camera will make video record as crime evidence and help finding the criminal.
A professional alarm system can well prevent burglary cause the burglary crime will be noted immediately and be recorded. It does not only scare the theft but also stop the crime by warning the theft with listen-in and intercom function. More over, it records the crime scene and punish the criminal if the crime is not stopped.
How to well use the burglar alarm system? Read the alarm system instruction manual carefully and understand the functions. Then enable and set the functions according to your home security needs.
Of course, planning and making a suitable home security solution is the first step.
You can easy add more sensors detectors to your exist alarm system. For example, solar power wireless infrared beam sensor can be added for perimeter security. Smoke and CO detector can be added for home environment safety. Some special detector such as outdoor curtain PIR is used for balcony, door, windows entrance detection and alert. All products are with tamper resistant function and anti destroy.

Home Security Solutions and Alarm System Installation
How to make home security solutions according to individual needs and budget? Below we will give an example to explain it. The house is with 3 bed rooms, 2 bath rooms, 1 kitchen room, 1 study room and 2 balcony.
The principle of making home security solution.
1.Plan and make external security firstly. In security alarm industry, it is perimeter security zones. The security protection areas are fence, wall, gate and house entrances including door, windows and balcony. The connection areas between the upper and lower floors, between house and neighbor’s house.
2.Then plan and make internal security. In security alarm industry, it is interior zones and fire zones. The security protection areas are aisle, hall, living room, kitchen room, bed room, bath room.
3.The alarm control panel installing principle:
A.Install it at place with telephone interface and hide it. Do not install it near the door or where theft can easy find and destroy it.
B.If the alarm control panel can not be installed at hidden place, then a PIR motion sensor should be installed to monitor the alarm control panel.
C.It is best to install the siren strobe outdoor and far from the alarm control panel.
D.If the siren strobe can not be installed outdoor, it is best to use wireless siren strobe and avoid theft finding the alarm control panel.
Step 1: Define the protection range according to the house situation.
From below drawing, we can know the most easy to be invaded place is two balconies, then is the out door. And kitchen room windows, study room windows cause these rooms are always vacant at night time and can be entrance of theft. Bath room, child room, main bed room are listed as protection areas with priority code.
All protection areas are listed with priority code from 10 to 1 as below.
Step 2: Define defense zones and defense way, equipment for each zone.
After protection areas and zone is defined, the defense equipment quantity and types should be defined according to the community security environment and family environment, behavior. The above home security solution design for example, we can use different equipment for different level defense. The equipment can be added or deducted according to budget and needs.
1.Simple type installation:
With lowest budget and good security environment, we make simple type installation. Only gate No.7, balconies No.9 and No.10, kitchen room No.6, study room No.5 are defensed. Wireless door magnetism contact is used for gate No.7, kitchen room No.6 and study room No.5. PIR motion sensor is used for living room and bedroom to against intrusion from two balconies No.9 and No.10.
The alarm system used is 1pc PIR motion sensor, 3 pcs door or windows open contact, one set alarm control panel with 1 PIR, 1 door contact, 2 keypad, remote controller.
The functions of the simple type alarm system.
A.When the gate or kitchen room window, study room window is opened, (door or window is leaving more than 1 cm from the door frame or window frame) or someone is entering into living room or bedroom from the balcony, the alarm system will go off and siren strobe makes sounder and lighting for warning.
B.Backup battery is built-in and can work for 8-16 hours at AC off time.
C.PIR motion sensor is used for zone 9 living room and home arm can be set when someone is at home. So, the living room PIR will not trigger alarm when someone is at home.
D.If no one is at home, away home arm should be set and intrusion is detected at living room, the alarm goes off.
The cons: When magnetic contact is used for windows security, the windows can not be opened even at summer time.
2.Basic type installation:
Use wireless door windows magnetic switch for all doors and windows. Use 1 PIR motion sensor for addition of living room security protection.
The functions of the basic type alarm system.
A.When the gate or kitchen room window, study room window, bathroom window, child room window is opened, (door or window is leaving more than 1 cm from the door frame or window frame) or someone is entering into living room or bedroom from the balcony, the alarm system will go off and siren strobe makes sounder and lighting for warning.
B. Backup battery is built-in and can work for 8-16 hours at AC off time.
C. PIR motion sensor is used for zone 9 living room and home arm can be set when someone is at home. So, the living room PIR will not trigger alarm when someone is at home.
D. If no one is at home, away home arm should be set and intrusion is detected at living room, the alarm goes off.
Cons: When magnetic contact is used for windows security, the windows can not be opened even at summer time. When someone is at home, home arm should be set.
3.Practical type installation:
Cause the basic type alarm system using windows contact for windows protection and the windows can not be opened at arm status, the curtain PIR is used to replace windows contact. The curtain PIR is with direction recognition and alarm goes off if theft entering from outdoor. The alarm will not go off if home owners is walking at home.
Cons: The balcony security protection is not enough. The theft can enter into balcony without alarm going off. It alarms until theft goes into the house.
4.High grade type installation:
Use infrared fence as balcony and windows intrusion prevention security equipment. The infrared fence is installed outdoor and can stop intrusion outdoor. Smoke detectors and gas leakage sensors are used as well for fire prevention.
Solar power wireless infrared fence can be used. It is easy to install and there is wireless to wired transceiver for connection with any third party alarm control panel.
Smoke alarm and gas alarm should be set as 24 hours zone and not controlled by arm disarm setting.
5.Complete type installation:
With infrared fence installed outdoor for windows and door entrance prevention. And add outdoor PIR detector as well at balcony to ensure the alarm going off when the theft is at balcony. Add wireless siren strobe for warning and neighbor notice. So, home is more secured.
6.Thorough security solution with smart home
Smart home house appliance switch is added to complete type installation alarm system. The house appliance such as air conditioner, electric cooker, electric heater can be remote turned on or turned off by mobile phone, remote, smart home app or telephone calling.

Combustible gas leakage disposing
Natural gas, LPG is used for home cooking, heating. But the gas is with dangers if it is not used properly. So, people should know how to use the gas source correctly. A gas detector is not enough for home gas security. A connected solenoid valve is better for gas source leakage shut off.
What should we do if gas leakage is detected? The fire fighting person said:”When we are at gas leakage spot, we even dare not kick the door or knock, smash with a metal tool. Because that may produce spark and detonate gas.” We should remember what we must not do at gas leakage spot.
1.No fire is allowed, no smoking, no lighter. Otherwise the leakage gas make be detonated.
2.No turning on/off of house appliance. Because that may produce spark and detonate gas.
3.Do not dial telephone at gas leakage spot. Because that may produce spark and detonate gas.
What should we do then when we find gas leakage?
1.Shut off gas source. Tighten the LPG bottle valve. Open the doors and windows for ventilation. Can use a broom to disperse gas leakage in air.
2.If the LPG bottle is with cracks, it should be gently moved to the outdoor ventilation place.
3.If large amount gas leakage is found, please leave the spot immediately. Cut off the power supply. Extinguish all fire. Go outdoor and call for help.
4.If gas leakage is found from neighbor home, please knock the door to notice it. Do not press the door bell.
