The Tech and Technique Behind Effective Home Surveillance

By Jackie Edwards

The video surveillance industry continues to develop and prosper as awareness for safety grows among citizens concerned for the security of their homes. According to a poll conducted in 2018 by SDM, in which both integrators and dealers were asked about their state of confidence with the current surveillance market, 75% said they believed the market’s state to be excellent. As video surveillance continues to grow in prominence and ubiquity, with more homeowners looking to secure their households, the more technical aspects of home surveillance should be made transparent and readily available. Placement technique and varying types of surveillance systems are being continually innovated and specialized towards fostering intuitive home security setups. Here’s an overview of the current standards for installing CCTV systems and their variant iterations.

Conventional surveillance setup 

A conventional surveillance setup is comprised of either mountable or stand-alone cameras, positioned independently in various areas which work in conjunction with each other to capture consistent video. The collective of cameras send footage to a monitor system; the signal being broadcast from the cameras to the monitors is closed circuit. Viewing of the camera’s feed is strictly observable from connected equipment. The majority of modern surveillance cameras capture high resolution video and are best situated in corner areas of an indoor space, since they are typically capable of wide range viewing. The system itself is conventionally connected by coaxial cables. Inconspicuous and out of reach, wired systems are still commonly used by homeowners to deter potential burglary and more generally maintain consistent observance of their property.

Wireless configuration 

As a means of eliminating the need for cumbersome wire installation, newer surveillance systems are entirely wireless. Composed of a camera, transmitter, receiver, visual monitor, and a supplemental data storage system, wireless setups allow for broader range in regards to placement and proximity from the central monitoring unit. Footage is captured and streamed from a radio transmitter to an antenna; the receivers can either be based within the camera and monitor or separate from one another. Being wireless, these units are able to be disguised as everyday items, or can be totally mobilized and mounted onto a tripod or other peripheral.

Flexibility of location for surveillance

Areas of the home that experience the most break-ins are the front door, backyard, and the ground floor parallel to the house. What should be considered when plotting effective surveillance locations is the camera’s proximity to a power supply and proximity to the home’s router – if wireless. Integration of IoT principles makes it possible to use a smart device for wireless monitoring of the surveillance feed. Some cameras are designed for communication with other smart and IoT outfitted devices. Homeowners are granted the flexibility to place camera’s base on their own concerns for which area of the home is considered a security risk.

Freedom for homeowner’s and how they arm their home is the priority for surveillance companies. As the industry continues to develop along with smart technology’s integration to domestic life, surveillance systems will persist in popularity and normalcy.

The Science Behind Welding

By Megan Ray Nichols

When you want to join two things together, you have a lot of options depending on the two materials. If you attach paper to cardboard, you can grab a bottle of glue. If you stick plastics together, epoxy is your go-to adhesive. If you try to attach two different pieces of metal, glue won’t cut it. That’s where welding comes in. Let’s take a look at the science of welding, as well as the different types of welding and how they work.

The Science of Welding

The science of welding depends on the type of metals you want to join, as well as the kind of filler material you use to attach the pieces. The most common type of welding is known as arc welding, which gets its name from using an electrical arc to melt both the metals and the filler to create a solid connection or joint between the two.

Start by attaching a grounding wire to the welding material. Then an electrode gets attached to the piece you weld and an electrical arc is generated between the two points, creating a high-temperature area that melts the metal and the filler, creating a uniform joint. Welding is tricky because you need to continuously feed the filler into the welding joint at an even rate to create a uniform weld.

Now that you understand the basics of welding, let’s take a closer look at the different types of welding, including the common less common options. There are 30 different types of welding, ranging from simple to complex.

MIG – Gas Metal Arc Welding

MIG welding is a type of arc welding that uses a shielding gas to reduce the combustibility of the materials. This type of welding reduces waste because it uses a high-efficiency electrode that creates cleaner welds. MIG welds are usually found in the automotive, industrial, robotics and maritime industry.

TIG – Gas Tungsten Arc Welding

TIG welding, also known as heliarc welding, uses a tungsten electrode that can be used with or without a filler rod to melt two metal pieces together. Like MIG welding, this style also uses an external gas supply — most commonly a mixture of helium and argon. You’ll usually find TIG welding in the aerospace industry, water pipe joints and motorcycle manufacturing.

Best Tips For Teaching Students To Develop Their Scientific Writing Skills

Writing is not an easy skill, no matter how simple it may seem at a first glance. But, you need it to go through your education with success Everything is based on writing when in school and if you have good writing skills, you will do better in everything. Exams, essays and so on, all have a huge impact on your school results and they all require writing.

As a teacher, you need to help every single student improve their skills and acquire new writing skills. Your students will become better people as a result of this.

But, most teachers don’t realize that they will need to provide a lot of help for their students so that they can develop these skills. They have a responsibility to do this. While your students can improve your skills without working hard, you have to be there to make sure that they are doing a good job.

Follow these tips to help your students learn more and better:

Encourage good and penalize bad writing

Some teachers want to get good results but never want to do anything about it. They never motivate their students properly and if they want their students to work well, they have to ask for the results. Let your students know that they will get a reward for good writing and that they will be punished for bad writing. Let them know that those who make great efforts to write well while being thoughtful and clear will be able to get some extra points and better grades and that those who work less and make less efforts to write well will be penalized with negative points or worse grades.

Build their mindset

Clear rules and expectations are not always enough and they might not work on all of your students. So, you have to inspire them to create great papers by letting them know just how important writing skills are. This is motivating them rather than scaring them. “You can make them understand that good writing extends beyond just school and that it’s crucial for success. Give them examples of people who have succeeded in their life because of writing skills and people who failed because they missed out on learning how to write properly” says Delia Plants, copy-editor at Stateofwriting and Australian help.

Allow them to practice a lot

Every skill gets better with practice. Repetitive work makes it better and more high quality. Small changes in your routine will make it easy for you to organize practice lessons and you can do this every day. Ask for a small amount of words on a specific topic so that they can practice being succinct and brief while still going in-depth on a certain subject. It can be boring and tedious for them at first but their skills will definitely improve. They will start writing so much better than they did before and this will create a huge improvement in their life. Diversify topics and genres. They can write non-fiction one day and then put their imagination to good use and write fiction the next day, Involve them in homework, assignments, exams and so on.

Instruct them through the writing process

When you provide your students with an assignment, you should explain how they can start writing it and how they can make it through all of the elements of good writing. Take some time to talk with them and address their concerns and issues. You can emphasize the importance of creating an outline.

You can also give them a good starting points and tell them about techniques, methods and so on that will help them save time and energy. They will be able to memorize these things and their skills will get better with time,” says Jorge Nesbit, editorial assistant at Oxessays and Academized.

Give feedback

You can also give them feedback during this process. You can share with them many different things about when they did well, what they did wrong, what they can still improve on etc.

Become their role model and mentor and share with them useful feedback.

Help them read a lot

Good writers are also experienced readers. You should give your students plenty of time to read and even create one assignments where they have to read a book every week. This will expand their vocabulary and help them write better.

While writing isn’t rocket science, you can help your students learn better and faster if you know how to do that. Use these tips to improve your student’s writing skills.
