Do you like to install your security cameras in obvious locations to maximize their visibility? Do you often try to make your security cameras as obvious as possible? Have you ever wished your security cameras could warn intruders that they're being watched? Historically, the main purpose of a security camera is to capture evidence should an unfortunate event occur. Other than the deterrent of simply having one, however, security cameras don’t actively prevent these events. But not anymore! We have some new Active Deterrence cameras at LINOVISION. With visual and auditory warnings built right into these cameras, with their bright LED spotlight and loud siren, are designed to stop people in their tracks. you'll never have to worry about your surveillance going unnoticed by intruders again.
Before we jump into these cameras and their awesome features, let's start with the question you might be asking yourself right now: what even is active deterrence?
When you put up a security camera, it's probably because you want to make sure that the areas under your surveillance are crime-free. Because of this, any security camera install is considered an act of deterrence. However, most of the time the security cameras stand by, keeping a close yet silent eye on your property. It will surely capture any criminal activity on video. It may even alert you through a recorder or mobile notification. However, these cameras won't do anything on their own to prevent the crime from happening. They are passive.
Oppositely, active deterrence is any additional measure taken by a surveillance system to ward off potential intruders and to, well, actively deter crime. Our Active Deterrence Cameras will not sit idly by while an intruder appears on the scene. These cameras have the ability to warn potential criminals through a motion-actived strobe light, siren, and voice. It may sound simple at first, but for features like this to be useful, it takes some pretty advanced motion-detection technology.
Active Deterrence Features
When looking for an active deterrence security camera, there are a couple of things to look for. First, and most obviously, the camera needs a way to alert intruders of its presence. Second, and less obviously, the camera needs to be able to recognize human agency and distinguish relevant motion from the irrelevant. Our Deterrence Cameras knock both of these requirements out of the park. Let's take a closer look at how these cameras actively deter.
Visual Warning
When you take a look at the camera, the first thing you will notice is the strobe light right under the lens. When it detects motion, it will flash repeatedly, alerting anyone nearby of its presence. In the camera's web interface, you can adjust the strobe light's duration and frequency. Depending on how you have it set up, the strobe light will flash for anywhere between one second and one minute.
Less noticeable at first glance is the onboard speakers, located on the bottom of the camera. If the strobe light doesn't catch the attention of the intruder, then the audible warnings sure will. You can choose between several different sounds, including a siren, a voice, or a combination of the two.
Intelligent Motion Detection
This camera's motion-activated strobe light and audible warnings are fantastic. But on their own, they're really not that useful. This camera's intelligent motion detection features really hold everything together and make this camera stand out as one of the best active deterrence security cameras available. You see, cameras that use standard pixel-based motion detection are not super reliable, as the motion detection alarm is triggered anytime the pixels move around on the screen. These cameras will consider pretty much anything "motion," whether it's a burglar breaking into your home or a piece of dust floating by the camera's lens. For a normal surveillance solution, this isn't much of a big deal. It may fill up your hard drive with a ton of recordings, but it will still reliably capture all movement.
However, when it comes to active deterrence, these standard pixel-based motion detection cameras just won't hold up. Think about it. If you set your camera up to sound a siren and flash a light every time it senses movement, false alarms are a little bit more of a nuisance than if the camera was just recording video. For this reason, these active deterrence cameras bring a whole new motion-detection technology into our Active Deterrence cameras.
Active Deterrence Motion Detection
The intelligent motion detection on these active deterrence security cameras is pixel-based motion detection on steroids. It is still based on pixel motion, so unlike Passive Infrared motion detection (PIR), it can detect motion for as far as the camera can see. The difference between these cameras and a standard motion detection camera is its smart filters. Using a very high tech and complicated algorithm, these active deterrence cameras can actually tell the difference between human motion and other kinds of motion.
How does Active Deterrence Smart Motion Detection Work?
So let's say a bird hops across the parking lot, right down the middle of your deterrence camera's field of view. The camera will register the change in pixels and know that motion is happening. But before it does anything, it's going to analyze whatever it is that's causing the change in pixels. It will take the shape of whatever is moving, in this case, the bird. It will compare that shape to the thousands of shapes in its database. It will then classify the moving shape into one of three categories: human, vehicle, or other. Our little bird here will fall into the third category, and the camera will completely ignore the motion.
If, however, the camera decides that the moving object is either a human or a vehicle, it will register the motion as important. You can actually see this process directly from the live view on the camera's web interface. You can see in the images and video below that the green box around the human and the vehicle turn red once the camera registers the motion as important.
But wait, there's more! This amazing technology puts control in your hands. Would you like your camera to only target human motion and ignore vehicles? You can do that. The camera will still register vehicle motion as important, so the lines will still turn red. But the camera will not sound the alarm or start a recording. Want to target vehicles and not humans? Or both humans and vehicles? Whatever it is you have in mind for these cameras, you can easily accomplish in just a few clicks.
How Accurate is Active Deterrence Smart Motion Detection?
Here's the big question that I know you're probably asking right now. This technology sounds great and all, but does it work? How accurate is it? Will it really cut out all false alarms? Well, like all technology, it has its limitations. It's not going to give you accurate results 100% of the time. For instance, sometimes the active deterrence security camera installed in our back parking lot thought this yellow pole here was a human and registered some irrelevant motion as important. Sometimes it thought these people walking in front of cars were actually cars themselves. So I'm not going to sit here and tell you that you're never going to have a false alarm again. But here's what I can tell you with confidence. These active deterrence security cameras will reduce the amount of false alarms you experience from standard motion detection cameras by at least 90%.
Active Deterrence Camera Uses and Examples
So far, we've talked about the theory behind these cameras, their deterrence features, and their smart motion events. Now we're going to get practical. If you're wondering how you would use one of these cameras, here are a few ideas to get your creative juices pumping.
● Looking for a way to prevent copper theft from your air conditioner unit? Scare off copper thieves with your deterrence siren and strobe.
● Do you manage a no parking zone? Throw one of these cameras up there and watch the illegal parkers flee the scene.
● What about boat docks or other restricted areas? These cameras are a great way to keep people out.
But even if you're not interested in the deterrence features of these cameras, the smart motion detection still makes them insanely useful. If you disable the sounds and strobe, you can still benefit from these cameras.
● Want to set up a standalone camera with an SD card? Cameras can't hold as much space as a recorder. With their smart events, these cameras will save you tons of storage by only recording important motion.
● Looking for a way to receive push notifications to your cell phone based on activity on your property? Install one of these cameras and you'll only receive important push notifications. Install a standard motion detection camera and it'll blow up your phone day and night with false alarms.
● Do you want to see long distances in the dark? Okay, this doesn't have to do with smart motion detection. But our Active Deterrence bullet also has a super long IR range of 50m, perfect for any nighttime scenario.

Before COVID, employees usually cared only about maintaining a comfortable temperature and lighting in the office. Now, with the proven connection between air quality and transmission of viral diseases, office buildings are rushing to improve their HVAC systems to ensure their tenants have a safe working environment.
Monitoring and maintaining good air quality is more than a temporary practice. There are a whole variety of reasons why it should be routine. Air quality is an important factor in the improvement of the workspace, as it directly affects the health of employees, as well as their work productivity and mood.
The average person takes up to 23 thousand breaths and exhalations every day. According to studies, the air quality inside buildings can be up to 5-10 times worse than outside.
The connection between indoor environments and people’s mental health has become a hot topic among leading academics. Several years ago, Harvard and Stanford launched new academic programs focused on “Healthy Buildings”. These programs study the intersection between buildings and health sciences and conduct various studies on the relationship between air quality and our cognitive abilities.
A study conducted by a group of researchers led by Joseph Allan, a Harvard University professor and director of the “Healthy Buildings” program, showed that working in well-ventilated offices with low levels of indoor air pollution and CO2 leads to significantly higher cognitive functioning scores among employees. In 2015, for six days, 24 participants – designers, architects, engineers, marketing professionals, and programmers – worked in controlled office environments and passed cognitive tests.
Every day the conditions changed, but the participants weren’t aware of it. First, the researchers tested people's response to normal ventilation and doubled it, which is in line with the increased “gree” standards of buildings. On other days, they artificially increased the carbon dioxide and VOC levels. The VOC sources were common office items such as markers, building materials, cleaning products, and clothes after dry cleaning.
The results of the experiment were impressive. Volunteers performed 61% better on tests when air quality met “green” standards, and at higher standards, the so-called Green+, cognitive performance showed a 101% increase. Measuring different cognitive functions, the researchers observed the greatest effect on the areas of strategy, new information usage, and crisis response.
But to feel the negative impact of polluted air, there is no need to arrange experiments. These conditions often occur naturally. In meeting rooms and conference rooms, carbon dioxide levels skyrocket, as employees usually don’t open windows and doors so that noise from the street or nearby offices doesn’t interrupt work processes. As a result, people leave meeting rooms tired and with headaches.
In general, poor air quality is associated with increased fatigue and decreased concentration.
Higher productivity
Maintaining clean air has a direct economic effect on a company’s performance first of all due to its impact on employees’ productivity. The study found an increase in decision-making performance when the ventilation rate in offices was increased from 20 cfm/person to 40 cfm/person which would result in annual costs of less than $40 per person per year. This change in cognitive performance corresponded to a $6500 change in a typical office worker’s productivity: basic activity, information usage, breadth of approach, strategy, and crisis response.
Fewer sick leaves
Low levels of pollutants are associated with fewer triggers for people with asthma, allergies, and other respiratory conditions.
In the past, there were a number of studies regarding the effects of air pollution on influenza-like infections. Some of the studies pointed out that despite adults aged 25-59 being the most affected, all age groups are susceptible to flu during peak concentrations of PM2.5. In poorly ventilated buildings, the rate of respiratory diseases such as flu, influenza, and pneumonia leads to an increased number of sick leaves.
The costs associated with implementing green building strategies at the workplace might become a potential barrier for employers. However, the School of Public Health at Harvard University discovered that medical costs fall by about $3.27 for every dollar spent on wellness programs and that absenteeism costs fall by about $2.73 for every dollar spent.
Caring for air quality has a positive effect on employee retention, as it increases job satisfaction and improves the employer's image.
The World Green Building Council conducted a study on improving occupants’ satisfaction through realizing green practices such as working on acoustics, air quality, office materials, and lighting, which all affect economic performance.
For example, engineering and consulting company Cundall, with 170 employees in London, has focused on improving air quality, including regular monitoring of carbon dioxide and VOCs (volatile organic compounds). Together with other measures to reduce noise, it reduced absenteeism by 4 days per year per employee, reduced staff turnover by 27%, and, according to the company report, saved £ 200,000.

]]>LoRaWAN is defined as Long Range Wide Area Network and is a LoRa technology derived from LPWAN advancements and IoT’s need for reliable long distance networking capabilities.
LoRaWAN is considered a wireless communication standard that connects IoT devices to a network to communicate informational data sets over a long distance using minimal battery power. Consumer and industry demands for efficiency dictate the rate of LoRaWAN sensors expansion, the application of wireless sensors or IoT sensors grow as more devices come into demand to deliver more results effectively.
While the idea behind wireless sensor networks and IoT sensors are considered complex, we are going to break down the information and redeliver it in a clean and simple way.
LoRa and LoRaWAN are technical terms oftentimes used interchangeably with another, but are not by definition the same. They different and we’ll explain how.
LoRa alone stands for Long Range and is considered the physical (PHY) or first layer standard. Radio Bridge’s LoRa devices and wireless radio frequency technology is a long range, low power platform that has become a wireless standard for IoT sensors and networks globally.
LoRa technology enables the deployment of smart IoT applications that are tasked with solving worldwide challenges like energy efficiency, pollution control, infrastructure productivity, disaster prevention, and many other applications. LoRa refers to the physical implementation for transmitting radio signals using a multi-symbol chirped format to encode the information before transmission through a proprietary system. This is slightly different than LoRaWan.
LoRaWAN, on the other hand, uses LoRa and includes an additional MAC later consisting of application standards. LoRaWAN is a popular wireless communication standard that could be placed in a category with 3G, Bluetooth, GSM, LTE, etc., although it’s not the same. LoRaWAN has similar or greater range than a smartphone, the flexibility of Wi-Fi, the battery life comparable to a watch, and costs only a few bucks. LoRaWAN has many desirable features that make it an attractive standard for IoT sensors and devices.
What are the featured characteristics of LoRaWAN?
LoRaWAN is rooted in the physical LoRa layer and has a raw max data rate of 27 kbps. Given the low-power long-range capabilities of LoRaWAN wireless sensors, a single sensor or network of wireless IoT sensors can remain powered for roughly a decade before needing maintenance. Here are some key features of LoRaWAN:
· Bidirectional
· Long battery life (up to 10 years)
· Low cost
· Low data rate (0.27bps – 50kbps, avg. daily 10 kB)
· Long range (urban areas less than 5km, suburban areas less than 10km, VLOS less than 80km)
· Operates in unlicensed spectrum
· Secure (AES encryption)
As stated above, LoRa allows the three L’s, two of which are positive and the third subjective. The low power, long range, and low data rates allow wireless sensors and other LoRa technology to have many use cases in several industries. Gas/electricity/water wireless sensors metering can send current usage information a couple of times a day, while SMART parking can be configured to send messages when parking spots fill or open up, requires no cabling and is low maintenance.
LoRa technology can also be seen in SMART lighting to control and optimize traffic flows by observing streetlight status and operation. Environmental monitoring uses like observing humidity, pollution, radiation, sound, temperature, etc. This type of use can establish vital insights when coupled with geolocation.
This type of technology can also serve a purpose in asset management by reporting the status and location of certain specified assets like control lights, locks, etc. Tracking industries are able to streamline and effectively track goods, delivery vehicles as well as package status and delivery route alerts. Healthcare stands to see the benefits of LoRa networks.
Think about activity detection and fall monitoring sensors in hospitals and nursing homes. There is no charging needed, it’s long lasting and has strong network coverage.
For sake of simplicity LoRaWAN networks can be primarily illustrated by the following diagram:
Devices<–>LoRa radio <–>Gateway<–>Network Server <–>End Application
Looks linear, simple, and yet confusing and mysterious. How does this work and what does it mean? Upstream messages (data sent from the device) are encrypted and sent over LoRa radio through transmissions. The message is received by one or more gateways who then transfer the encrypted data over a network (typically IP cellular/Ethernet) to a network server. The network server is the software that authenticates the device and decrypts the LoRaWAN payload. The server then delivers the data packet to the appropriate end application.
This process can also happen in the inverse, better explained, messages can be sent downstream which allows the application to reconfigure the end devices. With this being said, LoRa was designed to use low energy, which means some devices are limited when listening for incoming data transmission. This factor is device dependent as described in the next section.
A LoRaWAN sensor device is anything that sends or receives informational data and is commonly carried out by devices like wireless sensors, detectors, and actuators. These devices come in 3 classes and are essentially a step up from the previous class.
For instance, a Class A device is only able to receive a message during a small window after it has sent an uplink message and then returns to a low power sleep state where it cannot receive new messages.
Class B is similar to A, but instead is able to listen for incoming messages following predetermined intervals.
Unlike Classes A and B, Class C is able to continuously listen for new incoming messages without entering sleep mode, however, this feature comes at the expense of higher energy usage and for that reason, many Class C devices are not battery operated.
The LoRaWAN standard uses two different message types: MAC messaging and data messaging. MAC messages are used as commands to control the radio and networking message. Data messages are the actual payload that is sent/received and is application or device specific. Since these sensors have limited messaging capabilities, MAC commands/messages are able to ride alongside data messages similar to piggybacking and numerous MAC messages can be released at one time.
LoRa uses radio frequency (RF) signals to communicate and operate in the unlicensed ISM spectrum. This means that anyone can openly use this band without paying or getting a license so long as regulations are followed as determined by the FCC in the US. Although LoRa operates in the ISM (Industrial, Science, Medical) band, the ranges within ISM fields vary greatly depending on geographical region.
LoRa provides the necessary ranges and data rate within the following geographical frequencies for specified wireless sensors: Europe: 868Mhz and 433 Mhz, US: 915Mhz and AUS: 915-928 Mhz. These differences prevent US devices and gateways from being compatible with European or Australian devices. There are several techniques LoRa uses to improve data reliability, however, the two most important ones are Spread Spectrum and Adaptive Data Rate (ADR).
Spread Spectrum: Originally developed for military applications increasing resistance to interference from noise and jamming. It does this by taking raw information and is spread across a larger frequency.
ADR: This allows augmentation of the data rate and transmit power to adjust the functioning of signal quality and distance to the gateway. A slow transmission will have a higher spreading factor that achieves longer and more reliable ranges.
A gateway can be thought of as an access point or modem. It’s receiving all LoRa radio messages sent by devices within range. If the gateway has a network server built in it will process the data payload locally, and if the network server is located in the cloud the gateway will simply relay the encrypted packet to the server.
Once a LoRa gateway has received a transmitted data packet (message), it will then continue upstream to a network server, considered the most intelligent or sophisticated area of the LoRaWAN network. Network servers are responsible for carrying out a list of various tasks that include:
· Decrypt LoRa payload data
· Provision devices to speak to the network
· Grouping incoming messages from all LoRaWAN gateways within its network and sensor range.
· Direct/advance incoming data to the appropriate end application.
· Regulate LoRa radio settings to the gateways.
· When there are multiple gateways, the best gateway within range is selected for downlink messages for that particular device.
· Data buffering: stores downlink data (messages) until a class A or B LoRa device is able to receive messages specified during configuration.
· Filter/Eliminate duplicate messages/data sent from a single device appearing across multiple gateways where devices are unknown by receiving gateways. Since there is no distinction, multiple gateways can receive the same data.
· Assess/monitor gateways and devices.
The network server in most instances will direct messages from a particular ID and port to a specified or predefined application. This typically happens by sending it to a web service (HTTP(S)) or by placing it in an MQTT queue to be sent to the right place at a determined interval.
The final step of data transmission in a LoRa network is the data sent to the actual end application. This is where manufacturers and developers will create code to parse messages received by devices relevant to the application being used. This is where the raw data is assembled into digestible information for the end user’s interpretation.
We’ve simplified the flow diagram so you can visually compare how these areas work with each other.
Lastly, security comes to mind. Since networks themselves do not need to be able to interpret the data received unless it pertains to network infrastructure or is relevant to the network itself. A network session key (NwkSKey) encrypts the messages and payloads in the event a MAC command is sent. This key signs the message allowing networks to verify the sender’s identity.
A second key is known as the application session key (AppSKey) and is responsible for encrypting the payload (actual data) and does not need to be recognized or known by the network server in order to forward the message where it needs to be. The application server will then decrypt the message to extract the information by using the same key.
There are two secure ways to join a LoRa network. They are referred to as Activation by Personalization (ABP) and Over the Air Activation (OTAA). This determines how LoRaWAN devices connect to networks, but does not involve upstream-downstream communication flow as we’ve detailed above.
