VEDARD SECURITY ALARMS

Carbon monoxide is a flammable gas and a toxic gas as well. According to the requirements of the design code for detecting flammable gases and toxic gases in petrochemical industry, only toxic gas detectors should be set up. Therefore, when choosing a detector where carbon monoxide is likely to leak, you should choose a carbon monoxide poisonous gas detector. Carbon monoxide detector can be used as a detection device for the poisonous gas carbon monoxide.Connect it to the combustible gas alarm controller in the combustible gas detection and alarm system. https://vedard.com/blog/co-carbon-monoxide-detector/ https://www.vedard.com/forum/smoke-and-heat-detector-relay-output-t15.html

Monitor Net centralized comprehensive management platform is a comprehensive business management platform with alarm video as the core, network as the transmission link, and Internet thinking, big data, cloud computing and intelligent technology system integration. It has the functions of unified storage, centralized display and centralized management based on the platform by connecting the subsystem devices in the security system. It includes video surveillance, alarm, fire safety, access control management, patrol, intelligent analysis, intelligent control, information management and other security technology systems and equipment. https://www.vedard.com/forum/cms-server-operation-t7028.html

As we know, mobile phones and other wireless electronic devices are generally prohibited in flammable and explosive dangerous places such as oil depots or gas filling stations. Because gasoline is a volatile substance, oil and gas tanks and natural gas pipelines may leak and form a combustible gas danger zone, the radio frequency spark generated by mobile phones is easy to cause explosions, leading to disasters. Is there also a risk of explosion if wireless electronic alarms are installed at the perimeter of such places? Flammable and explosive places such as oil depots or gas filling stations must avoid the connection of conductive cables, so as to avoid the generation of strong electricity or electrostatic sparks. Solar Wireless Intrusion Detector Infrared beam is designed according to industrial and commercial security standards. It can be used at gas station or oil depots cause of following features. https://vedard.com/blog/can-solar-beam-be-used-at-gas-station-or-oil-depots/

Larger security projects require the linkage of alarm system and video surveillance. But the anti-theft alarms and video surveillance equipment are made by different manufacturers.Their communication protocols are different.Therefore, a certain way is needed to set the linkage of these two devices. There are three linkage modes of burglar alarm and video surveillance system. 1.The linkage of alarm device and DVR/NVR (relay output signal linkage) The alarm panel has 485 communication interface, it will send alarm data to linkage module when it receives alarm from wired and wireless detectors. The linkage module (always 32 channels) will be connected with DVR/NVR and transfer the alarm data to DVR/NVR (the DVR/NVR should have alarm linkage input interface). The linkage function can be set on the DVR/NVR software. https://vedard.com/blog/linkage-of-burglar-alarm-and-video-surveillance-system/

Beam system is active infrared detector. It is consist of transmitter terminal, receive terminal, Optical lens, LED indicator for light intensity etc. The system works as invisible light wall. When someone is entering into the light wall, it blocked the beams. Then the detector triggers alarm for warning and notice. The beam system keeps working 24 hours. To avoid false alarm of blocking by falling leaves, flying bird or small animals, the blocking time should be set not too short. But to ensure no missing alarm of quick passing theft, the blocking time should be set not too long. So, the blocking time or named sensitivity should be set accurately according to the environment. Factories may make the sensitivity adjustable at set value. https://vedard.com/blog/what-is-beam-system-and-how-does-it-work/

Sound and light alarm is needed for intelligent parking lot. It is installed on site and when dangers are found and confirmed, sound and light alarm will be triggered by alarm control panel. Loud sound and strong light will alert people on site. It has two functions: 1.Alarm prompts intelligent parking direction and speed When the vehicle is driven from the ground to the underground, sudden vision fainting and the downhill section of the road will cause the speed increasing. At this time, if the speed is not well controlled, it will directly hit the wall or pedestrians. So, a sound and light alarm device is needed. The sound and light alarm device is installed at the entrance of the underground parking lot. When a vehicle is entering into the parking lot, the sound and light alarm device will sense the vehicle and immediately send out the sound and light alarm to prompt the driver to pay attention to the direction and slow down.
