Security Camera Home Defense

If you’ve ever had a package stolen from your porch or had a car broken into while parked in your driveway, there’s a good chance that the perpetrator was long gone before you even found out you had been victimized. There’s an even better chance that you’ll never know who committed the deed. If this sounds familiar, it might be time to invest in an outdoor security camera.

These rugged smart home devices, designed to withstand rain, snow, and extreme temperatures, typically connect to your home Wi-Fi network and allow you to view live video footage of activities occurring outside of your house. They’ll also send an alert to your phone when someone or something is out there, record video of the event, and depending on features, let you talk to whoever is on your property, all without ever having to open your door (or even be inside your house, for that matter).

Read on to find out what features to look for when choosing an outdoor security camera, and to check out our top picks. Note that a number of the cameras on this list are suitable for use both indoors and out. If you want a model that’s geared specifially for keeping tabs of what’s going on inside your home, head over to our list of the Best Indoor Home Security Cameras.

How Do Outdoor Security Cameras Work?

Most smart outdoor security cameras use a Wi-Fi radio to connect to your home network, allowing you to access them from anywhere using a mobile app. But there are also models that can use wired Ethernet, Bluetooth, Z-Wave, or a proprietary wireless technology to connect to a mobile app or a dedicated hub.

Wi-Fi cameras are easier to install than their wired counterparts because they don’t have to be located near an Ethernet port and don’t require wiring. Battery-powered Wi-Fi cameras are the easiest to install because you can put them just about anywhere (as long as they can connect to your router) without having to snake a power cable into your home to plug into an outlet. These types of cameras typically use rechargeable batteries that can be easily popped out and taken indoors for charging with a USB cable, but they tend to drain quickly in colder weather. Bluetooth cameras are also easy to install, but you have to stay within 40 feet or so to connect to them with your phone.

Look for an outdoor Wi-Fi camera that can connect to either the 2.4GHz or 5GHz radio band to alleviate network congestion. If you’re having trouble getting a good signal outside, try pumping it up with a wireless range extender.

Application range of infrared camera

The development of security technology has received more and more attention from all aspects of society. The scale of the domestic security market has gradually expanded after the new century, and the functional requirements of users for security products have also changed. In the past, only visible light monitoring could no longer meet people’s monitoring requirements. Nighttime no-light monitoring is an indispensable and important part of the monitoring system.

Infrared plays an important role in night surveillance. It is not only used in general monitoring systems, but also in important departments such as treasury, oil depot, armory, library and literature library, cultural relics department, prison, etc. Infrared is also used in TV monitoring projects in residential areas today. In order to adapt to the application in special places such as night or dark light, no light, infrared technology came into being. It has been widely recognized in the entire video surveillance field. Infrared camera also integrates various technologies such as camera and infrared, and its configured components include lens and infrared lamp.

Infrared camera sales have now surpassed the sales of traditional rifle cameras. It has become the main export force of many private security enterprises in China, and we can even see a simple innovation similar to this installation of LED infrared lamp modules. Infrared shooting camera with day and night conversion function. The camera has the ability to sense infrared light and can cooperate well with the infrared lamp to effectively achieve 24-hour video surveillance.

Why use thermometer to measure and calibrate first

The biggest obstacle to real temperature measurement by radiation thermometry is the influence of the emissivity of the measured object. In addition, the reliability of the original measurement, the temperature of the test environment, and personnel operations all have an impact on the measurement results.

Measurement calibration can eliminate the error of the instrument itself and make the measured value as close to the true value as possible.

When performing measurement calibration, if the thermometer has a calibration correction function, the calibration value can be written into the instrument for correction; if it does not have the calibration correction function, the calibration value can also be given for reference in specific use.

The temperature value measured will be as accurate and reliable as possible after selecting a temperature measurement product whose accuracy and accuracy meet the standards, performing measurement calibration, and standardizing the operation of personnel.

“To create value for customers, to provide a platform for the strugglers, to contribute to the progress of society”, make the world more secure, ULIRVISION is determined to be a respected, globally renowned professional company which is leading in infrared thermal imaging, UV imaging as well as gas imaging industry.

What to pay attention to when choosing a thermal imager

The high-quality thermal imager must be a product whose accuracy and precision meet the standards.

At present, there are many brands of thermal imagers on the market, but the technical indicators are uneven. Some have high accuracy and poor accuracy. For example, your actual body temperature is 36.5 ° C, measured three times, respectively 37.2 ° C, 37.3 ° C, and 37.3 ° C. The amplitudes of the three values are not much different. The accuracy is no problem, but it is far from actual The 36.5 ° C is quite different and inaccurate; some have high accuracy and poor accuracy, or the previous example, the actual 36.5 ° C, measured 3 times, respectively 36.3 ° C, 36.6 ° C, 36.7 ° C, and the actual temperature of 36.5 ° C Both are close and fairly accurate, but the direct error of each time value is relatively large, and the repeatability is not good.

Therefore, when choosing, try to choose products of manufacturers with strong technical strength and high social recognition. At the same time, it is also necessary to calibrate the temperature measuring instrument to improve the accuracy and reliability of the temperature measurement.

ULIRVISION has more than a research team of more than 100 researchers in optical design, electronic technology, image algorithms, information processing, precision machinery, system integration, remote control, etc.

Infrared temperature measurement, which instrument performs best

Handheld thermometer is an application of infrared thermometer. At present, there are many infrared thermal imagers used in areas where people flow is concentrated. This kind of equipment can measure temperature in large quantities at the same time, with high efficiency, and basically does not affect the speed of crowds.

Infrared thermal imager converts the thermal radiation on the surface of the object into a visible image, which can accurately measure the surface temperature and temperature distribution of the object, and is more suitable for the comprehensive monitoring and measurement of the body temperature of mobile personnel.

In addition, there is an infrared human body temperature screening system, which is a little more complicated than infrared thermal imagers and has better functions. During the measurement, the crowd can stop the measurement in front of the big screen. Compared with the general measurement method, in addition to the advantages of high accuracy, high efficiency, anti-cross infection, green safety, etc., this temperature screening system can also achieve the traceability of suspected infection.

Is infrared temperature measuring the real temperature of the human body?

Radiation thermometers now have photoelectric pyrometers, infrared thermometers, full radiation thermometers and other types. Due to the problem that emissivity cannot be eliminated, the temperature measured by these radiation thermometers is not the real temperature, but the brightness temperature or radiation temperature of the object.

In order to solve this problem, the concept of apparent temperature was introduced in radiation thermometry. This allows the temperature measurement of the actual object to be directly related to the law of blackbody radiation without the emissivity of the object.

The infrared thermal imaging technology currently used is to measure the temperature by detecting the thermal radiation on the human surface. Based on the human body temperature measurement big data, the heat radiation data on the human surface is mapped to the internal temperature of the human body through the temperature measurement algorithm. Through the detection of the surface temperature of the human body, quickly find individuals with abnormal body temperature.

Is non-contact temperature measurement reliable?

Temperature measurement methods can be divided into two types: contact method and non-contact method.

Among the contact temperature measurement methods, thermocouples and resistance thermometers are the most widely used. This method is simple to operate and measures the real temperature of the object. The disadvantage is that the dynamic characteristics are poor, and because of the need to contact the measured object, the measured object The temperature field distribution will have an impact, that is, it will affect the temperature of the measured object.

Non-contact temperature measurement method is still dominated by radiation temperature measurement method. For quite a long time in the past, the reliability and anti-interference of the radiation temperature measurement method are not very high. However, in the past two decades, due to the development and application of technologies in electronics, semiconductor materials, computers, etc., the radiation thermometer has a fast response speed, does not contact the measured object and thus does not affect the measured temperature field. The advantages can be fully reflected. Wen technology has also made great progress, and its application has become more and more extensive.

AR glasses measure the temperature of tourists in seconds

With the improvement of the epidemic prevention and control situation, Xixi Wetland Hongyuan, a 5A-level scenic spot, has received 10,000 visitors per day. The scenic area introduced a high-tech intelligent temperature measuring glasses, real-time, efficient and convenient to measure the temperature of the mobile people in the park, using black technology to escort tourists safely.

At the entrance of the Xiyuan Wetland Hongyuan Scenic Area, security guards are wearing smart temperature AR glasses to check the temperature of people entering and leaving. From the appearance, this glasses is very similar to everyday sunglasses. However, when the wearer scans the person in front of the field of view in real time, the temperature value of the other party will immediately appear in front of the lens.

Brother Hong, a security guard, said with a smile: “It’s very light. This kind only needs people in the near future and can basically be detected.”

It is understood that this smart temperature measuring glasses were originally developed by local AR companies. The glasses are equipped with an infrared temperature measurement module, and the accurate temperature measurement time does not exceed 0.2 seconds, and can detect up to 100 people in 2 minutes. When encountering personnel with abnormal body temperature, the glasses will automatically alert and prompt, and save the personnel information records.

The person in charge introduced that its farthest (temperature measurement) distance can reach 3 meters. The epidemic prevention personnel and the inspected personnel are at a relatively safe distance. The second is that the experience is very good, you don’t need to hold the ear thermometer to his face, the third point is that he can move, it is patrollable.

Intelligent temperature measuring glasses have small errors and are easy to use. At present, the security personnel in Hongyuan Scenic Area and Xixi Art Collection Village have been equipped with this glasses to enhance the staff office and tourist play experience.

Shi Tianzi, the person in charge of Xixi Wetland Hongyuan, told the editor that it would not interfere with tourists or the normal working conditions of the staff. AR glasses measure48
