Detailed Product Description: | Section Lixin home burglar alarm / supermarket clothing store alarm / monitoring of Technology, Zhengzhou, Henan Name: Wang Tel: 15093372949 QQ: 562817342 1416735265 Address: Dongfeng Road, Zhengzhou City 300 Mi Milan West Wenhua Road, Building 4, Unit 1, 1105 the sun Selection of home burglar alarm in conjunction with home area, building construction features, property values, consider multiple factors such as surrounding environment, but there are few common reference standards: a wired communication, reliable, anti-jamming ability, low cost devices, for new and can be reserved within the walls of the building cable; but its poor mobility, inconvenience and products to adapt to changing user requirements, reserved for the maintenance and replacement of cables difficult and costly; wireless way to avoid probe and the connection line between the impact of the host interior decoration, with a flexible, simple advantages, but there are also a variety of factors susceptible to external interference, the device is relatively higher cost disadvantage. Section Lixin home burglar alarm / supermarket clothing store alarm / monitoring of Technology, Zhengzhou, Henan Prevent thieves from the door into the means of mature, namely the use of magnetic reed switch / magnet on the door to detect the open. But we know that there is an immediate alarm and alarm delay alarm is triggered in two different ways, the former can be immediate on-site alarms, the intruder deterrent effect immediately, but if the user did not I open the door to disarm operation such as, will generate false alarms and the user himself and neighborhood harassment. Alarm triggered after a delayed opening in the door when the beeper will sound, indicating forget disarm disarm operation of the user in a timely manner, if in a certain period of time the host has not received disarm signal, and the host alarm. Obviously, the latter approach is more practical. Prevent thieves from window into the current common means is the use of passive infrared sensor, the initial single-Kam (using only a single thermal element)-type susceptible to light, temperature and other factors, resulting in false alarms; more susceptible mice, cats, dogs, etc. false triggering caused by small animals. Later evolved a diverse (with more than one thermal component) type, and Shuangjian (using thermal and microwave two components) type, or three warning (use of thermal and microwave two kinds of dollars through the microcontroller operation processing) type in order to reduce the incidence of false alarms. Section Lixin home burglar alarm / supermarket clothing store alarm / monitoring of Technology, Zhengzhou, Henan In addition to this type of probe is easy to produce false alarms and only once in the indoor environment, there is the problem restricted to use in the home: the defense of such probes is three-dimensional rather than flat area, a master in indoor activities , can not be closed to the room full deployment. The latest method is the use of the infrared beam invisible network security, there are two types of such equipment: outdoor power adapter required; wireless transmission, can be 5 ~ 30m distance outside the walls, doors, the same wall plane the formation of a window or fan-shaped defense mesh plane can be true of the building "completely closed" defense; indoor battery-powered; wireless transmission, can be installed in the balcony room windows, doors, both sides of the aisle , for 1 ~ 8m from the implementation of linear defense; such equipment can be true of the building "completely closed" defense; indoor as more diy (customer installable) convenience, enabling mobile defense, the more practical value. To prevent the robbery, first-aid assistance is Section Lixin home burglar alarm / supermarket clothing store alarm / monitoring of Technology, Zhengzhou, Henan Achieved with the emergency button, burglar alarm in the home should also be essential equipment. If the remote control and emergency button as a whole, should assess the emergency button to prevent accidental triggering capabilities. Fire prevention and anti-flammable gas leakage alarm also evaluate the performance of an indicator. Submitted to the police intelligence methods to evaluate the alarm price / performance ratio and availability of key indicators. Submitted to the most primitive way is to use the scene warning warning to people in the vicinity; more popular way is to submit the alarm host automatically dial the user's default phone number, dialed after the user can play pre-recorded instructions contact the police locations voice; and as a commercial residential district or community defense applications require a network alarm alarm host. Networked alarm receiving traditional means is the use of computer or telephone line from the line data, in comparison, the use of telephone lines to transmit data with a line of high reliability, maintenance-free, easy expansion and other obvious advantages. However, the use of computers to telephone lines to receive the data, it has its shortcomings: difficult to take an ordinary pc-machine around the clock continuous work, such as the use of non-stop continuous work can be adapted to the industrial control computer, and the soaring prices of the products 3 5 times, resulting in a waste of money; the use of computer skills required for operators of high, resulting in waste of human resources; always have to face the use of computer viruses, data loss, crashes and restarts and other fatal flaw. Section Lixin home burglar alarm / supermarket clothing store alarm / monitoring of Technology, Zhengzhou, Henan The distinction between the situation of the police was to evaluate the performance of an important indicator of alarm. Network alarm with the host should be able to distinguish between the police information (such as intrusion, emergency, fire, etc.), district (doors, windows, room location, etc.). Some product features of practical conflict with the standard (such as no power supply), some product features of conflict and defense purposes (such as remote disarm).
