Installing active infrared beams detector is harder than installing passive infrared detector. The beams detector is installed at outdoor open space. It is always fixed on pillar or on wall. We should firstly confirm the protection line and draw the installing place on drawing. Then we mark the accurate installing point on fixing object such as wall or pillar by level instrument or other tools.
Installing ways:
Installing the beams on pillar: there are some types of pillars such as pipe and square columns. The shapes are “1” shape, “z” shape or “L” shape. We should choose the correct type of pillar according to installing building feature and security protection requirement. The pillar should be fixed on ground or other objects strongly and without moving or shaking. It is important to ensure the beams detector installing and working properly.

2.Installing the beams on wall: the infrared beams can be installed on wall or fence, windows directly. The Optical lens of the detector has automatic up and down adjustment of 20 degree. Use fixing bracket to install the infrared beams on surface of wall or frame of windows.
Principles of installing infrared beams detectors:
Detectors installed on passageway: It is used to stop illegal passing and avoid false alarm caused by pet or small animals. So, the beams should be installed more than 50cm(from the infrared beams hole) over the ground. The beams blocking response speed should be set at fast rate.
Detectors installed on parapet wall: It is used to stop illegal climbing over the parapet wall. The beam can be installed over the top of the parapet wall or over the side of the parapet wall. It should be installed more than 25cm(from the infrared beams hole) over the top of the parapet wall to avoid false alarm caused by bird or cat etc. animals. And the distance should be less than 30cm between the beams hole and the wall inside part. When it is installed at side part of the parapet wall, it should be installed at outside part of the wall and near the top part.

The installation way should be chosen according to protection requirement and building features. 4 beams infrared detector performed better than 3 beams to avoid false alarm.

In the past, security system means surveillance video system. With the development of technology and people’s awareness of safety and prevention, various security devices have been developed that can predict in advance, intervene as early as possible, and prevent crimes and disasters.
Now, Security system is an integrated system of equipment which is composed of safety protection products and other related products. Security system equipment includes video surveillance system, perimeter alarm, anti-theft alarm system, access control system, parking and storage management system, patrol system. These subsystems used to be isolated from each other and communicate by themselves according to their own protocols. This causes great inconvenience to security management.
Through the security management software, we can easily link up these subsystems. But if there is no management software, the security alarm system can also be linked through the linkage interface. The linkage of the security system can make people more timely and accurate to understand what is happening on the scene. The linkage of the security system can trigger the active defense such as the door closing action of the access control system.

However, not all alarm mainframe can be flexibly linked to other security subsystems. Only the programmed alarm host with complex functions can be equipped with linkage output and linkage interfaces such as RS485 to trigger other security subsystems. Example of burglar alarm link with video surveillance.
The linkage of access control and alarm system is also the active defense of security system. When the alarm system triggers the alarm, the output relay voltage is sent to the access control panel to lock the door from supreme level. So, the burglar will be caught. One the other hand, when fire is detected, the alarm host will send fire signal to access control panel and unlock the door. So, people can escape from fire soon.
If use burglar alarm only, we may only get intrusion notify from email, app, phone, sms. But we do not have video evidence of it. If use CCTV surveillance only, we get video of intrusion, but they have been in your home. So, to build a safety net around your home, you need perimeter security equipment, such as solar break beam and windows solar infrared grating, curtain pir, motion sensor, glass break detector, security camera, door lock, smoke alarm, gas alarm, door magnetic switch and link them together.
Linkage security system can better ensure people’s home property and life safety. Each security subsystem of the new technology is equipped with input/output linkage and programmable linkage interface. Better use of the various functions of the security alarm system can more effectively do a good job of home security protection.

How to test and install solar beam system

June 9, 2021

 

 |  No Comments

Solar beam wireless perimeter security system is popular used for security protection of factory, community, warehouse, villa etc. It is easy to install without any wiring. It is easy to maintenance with fault, low battery report and tamper-resistant. It is easy to be added to exist security system with wireless signal adapter. It is easy to use with CMS security service management software.
How to test and install the solar beam system?
1. Test Method
To test the quality of wireless solar powered alarm beams, we should test 4 parts of the system. They are battery, infrared distance, wireless signal transmitting distance and solar panel charging capability at cloudy and rainy days.
A. Test of battery
The rate voltage of the battery is 4.2V. If the solar powered wireless beam works at illumination under 1600Lx for continual days and the battery voltage is down to 3.8V, the product will activate battery protection system. It will protect the battery from overusing and the solar powered beams don’t work now.
After the battery is recharged to 4.1V, it restart to work. At normal working environment, the battery starts to recharge when voltage is 3.9V and without low voltage protection.
Test 1:
Working time without sunlight
The solar powered beams can work for 20 days without sunlight.
Put the beams with battery installed at place without illumination such as drawer, box, then trigger it. The day before receiver terminal indicator doesn’t light on is the last work day.
Test 2:
Battery recharging time
At normal sunlight environment, the battery recharging time is 1 day. (from low voltage to full voltage)
Put the beam with battery installed at place full of sunlight, take down the battery and test its voltage after 1 day.
B. Test of infrared distance
The infrared distance of wireless solar powered beams is 100m
Install the batteries in beams, aiming and then enroll it to alarm panel. Take the transmitter and receiver beams to 100m distance, aiming again, receiver terminal indicator flash slow then flash fast and then light off. Trigger the beams, the alarm panel send out alarm signal.
C. Test of wireless transmitting distance
The distance between wireless beams and alarm panel is 100m (can reach to 1 km with high power)
Put the alarm panel at a place, enroll the wireless beams to the panel, put the beams at another place which is 100m from the panel, trigger the beams, the panel will alarm. Repeat to trigger the beams to test the stability.
D. Test of solar panel charging capability at bad days
Amorphous silicon solar panel is used for the beams. It enables the beams to be recharged at cloudy and rainy days.
At cloudy or rainy day, put the beam outdoor without battery installed. Place the solar panel towards outside. The beam indicator red LED will keep flashing. That means the solar panel is charging.
The solar panel works via absorbing UV light and can work at illumination level is over 1700Lx. The illumination can reach to 2500-2700Lx with sun light and reach to 2000Lx without sun light.

Notes of using the solar powered wireless beams
1. Trigger way
Only all beams are blocked, the product will trigger alarm. To avoid false alarm by animals and falling down things, the product is designed with required blocking speed. A thicker object such as a book is required for test. Not too fast speed is required to test. Please make sure the receiver indicator lights on when it is triggered. When the product is triggered, the receiver terminal indicator will light on, then light off. Only after it lights off, it will be on work status again for next time trigger. If the indicator is lighting on and now trigger it again, it will not send alarm signal.
2. Aiming
If transmitter terminal and receiver terminal are not aimed, the indicator of receiver will keep lighting on. When they are aimed, the receiver terminal indicator will flsh slow, then fast and lights off at last. Now, it is at work status.
3. Alarm Panel
Antenna of the alarm panel should be pulled out totally to ensure the receiving distance.
Remember to enroll the test beams to the alarm panel and arm the panel before test.
Avoid to test and use the wireless alarm products at places which is with high magnetism, high voltage equipment or metal objects.

Driveway Alarm System

August 2, 2021

 

 |  No Comments

A driveway alarm is a household reminder. Install an outdoor detector in the driveway or aisle entrance to your house. When the detector detects that a person or vehicle is entering the area, it immediately sends a wireless signal to the indoor receiver, which receives the signal and sends an alarm. Driveway alarms can also be used to protect backyards, garages, farms, etc.
What are the common types of driveway alarm system? Driveway alarm systems come standard with an outdoor wireless detector and an indoor receiver. Indoor receivers are mostly simple reminders with sound. Driveway alarm detectors, however, come in several different types.
1.Passive infrared detector
Passive infrared detector is to detect moving objects with temperature, such as human body, animals, and started vehicles that cross the protection area of the detector will be detected, and then send alarm signal to the receiving host. Conventional passive infrared detectors require frequent battery changes and the false alarm rate is high.
Solar passive infrared detectors use solar energy to charge, without frequent replacement of batteries. By optimizing the detection Angle and intelligent detection analysis technology, the solar passive infrared detector can effectively solve the problem that the passive infrared detector is easy to give false alarm outdoors. Solar passive infrared detectors are easy to install and are popular driveway alarm systems.

2.Metal detector
Metal detectors work by giving an alarm if a metal object is present in the detection area. The metal detector on the driveway alarm is basically divided into two parts, one is a metal detection sensor, generally buried in the underground near the driveway or corridor, the detection range is generally a circle with a radius of 1-3 meters. The other is a wireless signal transmitter, which is connected to a metal detection sensor by a wire. When a metal object is detected, the wireless transmitter sends an alarm signal to the receiving host in the room.But metal detectors only detect vehicles. Metal detectors are cumbersome to install and maintain, require digging trenches to bury them underground, and the wires are vulnerable to rodent damage. So metal detectors are not commonly used as driveway alarms.

3.Active infrared beam system
Active infrared beams work in pairs and include a transmitter and a receiver. The transmitting end sends out infrared beam, and the receiving end receives the infrared beam. When an object completely blocks the infrared beam, an alarm signal is immediately sent out. Solar wireless infrared beam with built-in LCD calibration device, is easy to install and not affected by outdoor wind and rain, it is with high detection reliability. Solar break beam system is a good choice for driveway alarm system.

Users can choose the appropriate driveway alarm system according to the actual use environment and demand. Driveway alarm detector is not only a simple reminder device on the driveway now, more and more users have begun to use these detectors as their outdoor anti-theft alarm products.

https://vedard.com/blog/the-three-elements-of-security-precaution/

 Home Security precautions include human precaution, physical precaution and technical precaution.

Human precautions include closing doors and windows, keeping house keys and door codes well, leaving valuables in a safe place before leaving your home, and personnel patrolling etc.
Physical precautions include strengthening doors and Windows, adding protective railings, fences, and locks.
Technical prevention means detection and early warning through the assistance of advanced science and technology such as sensor technology, electronic technology and computer technology. Technical security precautions include installation of anti-theft intrusion alarm system, video monitoring system and access control system.
The anti-theft invasion alarm system is equipped with three layers of defense on the outer wall, the doors and Windows of the outdoor courtyard corridor and the indoor space. Indoor and outdoor alarms are with different alarm technologies, such as active infrared alarm, passive infrared alarm, microwave alarm, dual technology alarm, cable alarm, laser alarm, etc.
The three basic elements of security prevention are detection, delay and response. Detection means to perceive the occurrence of explicit and implicit risk events and send out an alarm. Delay refers to the process of prolongs and postpones the occurrence of risk events. Response refers to the rapid action taken by the organization to prevent the occurrence of a risk event.

Three means of security prevention work on these three elements. The technical security system can give early warning in time, prevent effectively and dispose quickly. The digital security alarm system can accurately inform the alarm location and alarm type and send alarm information to the mobile phone and alarm center of the security personnel. The alarm system in conjunction with the smoke generator can make the scene of the crime shrouded in smoke, delaying the crime.
Taking home safety measures is the most effective way to prevent fire and burglary injuries. Intelligent and easy to operate technical safety protection equipment is a necessary appliance for home life. There are many kinds of family security alarm systems, some of them are combined with household appliances such as audio equipment, which are convenient to use. Home users can choose suitable security protection system according to their needs. At-home users can opt for a driveway alarm doorbell. Users who are not at home can choose to remotely monitor the APP alarm host.

A life-saving smoke alarm in a fire

 Why are so many people trapped in an indoor fire? According to statistics, more than 80 percent of those who died in the fire were smoke-choked. Fire combustion products contain a large number of toxic components, such as carbon monoxide, carbon dioxide, hydrogen cyanide, sulfur dioxide, nitrogen dioxide, etc., these gases have different degrees of harm to human body. One of the most toxic gases is carbon monoxide. Carbon dioxide is non-toxic, but when it reaches certain concentrations, it can stimulate a person’s respiratory center, resulting in shortness of breath, increased smoke inhalation, headaches, confusion and other symptoms. The vertical flow rate of flue gas is 3-5 meters per second, which is 8-10 times the horizontal flow rate.When the toxic smoke fills the entire evacuation channel, people may faint if they stay 1-2 minutes, and people may die if they stay 4-5 minutes.

Electrical and living fire carelessness is the two main causes of residential fire. The specific causes of electrical fire include line failure, electrical equipment failure, heating appliances used for a long time or too close to fuel, etc. The specific causes of careless use of fire in life are oil pan fire, baking, improper use of stoves, smoking, spontaneous combustion, playing with fire and so on. There are a lot of flammable objects in the room, some furniture, plastic combustion will produce a lot of smoke. The smoke would have lowered the line of sight so much that it was hard to see from a meter away. After the occurrence of an indoor fire, the escape time is limited. Under normal circumstances, the ordinary residence fire will deflagration in about three and a half minutes, and the chance of escaping after deflagration is very low.

The following measures can effectively reduce the occurrence of residential fires: timely replacement of aging and damaged electrical lines, replacement of old electrical appliances, regular inspection of gas lines, no smoking in bed, teaching children not to play with fire, keeping away from combustible materials when baking and heating, checking the use of electricity and gas before going to bed or going out, etc.
In addition, fire detection and alarm equipment should be installed in the home for early warning and early detection. Once there is a fire, the alarm device will trigger the alarm, even in the middle of the night people can evacuate and call fire police. Smoke alarms are the most commonly used fire alarm detectors. According to fire protection association, A smoke alarm should be installed in every bedroom, a smoke alarm should be installed outside the bedroom where the alarm can be heard through the door. At least one smoke alarm should be installed on each floor of the residence. The closer the alarm is to the fire, the faster it will work.Therefore, as many fire smoke alarms as possible should be installed in the residence.

There are many types of smoke detectors. Refer to another article at Fire safety cannot be ignored.
