Guardian Expert: Smart Alarm Phone Alarm Theft alarm system is a kind of intelligent alarm device that uses the telephone line communication network to transmit alarm information. It consists of an alarm controller, a wired detector, a wired magnetic switch and a camera.
If the thief breaks open the door and window, the system can immediately call the previously set alarm telephone number by telephone, such as the property, the owner's office, etc. At present, it is recommended to use passive infrared detectors for home burglary. Once a person's infrared radiation enters the warning zone, the detector will issue an alarm. It is understood that the price of such detectors ranges from two to three hundred to seven hundred and eighty yuan.
In addition to infrared detectors, you can also use the redundant interface on the alarm controller to pull a wire around the window to form a loop. As long as someone touches the wire, it will alarm, so that “the enemy is outdoorsâ€.
You can also set up a live alarm or set up a telephone alarm. Metal wire is an enameled wire that can be purchased in a hardware store. The finer the better, the best it can be to break the wire and connect it directly to the two interfaces of the alarm controller.

This kind of anti-theft device will also have some additional functions similar to the smart home system. For example, the owner can automatically start the water heater in his home at an hour before he works.

However, at present, this service requires consumers to apply to operators and charges are still high.
The COVID-19 Antigen Saliva Test kit is a lateral flow immunoassay intended for the preliminary screening and qualitative detection of nucleocapsid protein antigen from severe acuterespiratorysyndrome coronavirus SARS-CoV-2which causesthe Coronavirusdisease(COVID-19),in direct saliva sample from individuals suspected of coVD-19 by their healthcare provider within the first seven days of symptom onset.The COVID-19 Antigen Saliva Test kit is for professional use only and is intended to be used as an aid in the diagnosis of SARS CoV-2 infection.
SARS-CoV-2is anenvelopedsingle-stranded RNAvirus ofthe Baenus COVD-19 is an acute respiratory infectious disease. People are generally susceptible.Currently. the patients infected bytheSARS-CoV2are the main source ofinfection:asvmptomatic infected peope car also be an infectious source Based on thecurrentepidemiologica investigation, the incubation period is 1to 14 daysmostly 3to 7 days The main manifestations include feverfatigue and drycough.Nasa congestion, runny nosesore throatmyalgia and diarhea are found in a few cases.
Results are for the identification of SARS-CoV-2 nuceocapsid protein antigen. The SARS-CoV-2 antigen is generally detectable in upper respiratory specimens during the acute phase ofinfectionPositive results indicate the presence of SARS-CoV-2viralantigenshowever cinicai corelation with patient history and other diaanostic information is key to determine status of infection.Positive results don't preclude bacterialinfection or co-infection with other yiruses.eaatveresuts To patients with symptom onset for more than seven days should be treated as presumptive and confirmation with a molecular assayand patient management may be performed according to local regulations as needed.
