SecurityCameraKing is the Amendment 64 Security Camera Authority

Written By:
Tuesday, April 14th, 2015

We here at want to ensure you that when it comes to the needs of your surveillance equipment inspections for the Colorado Cannabis Community SecurityCameraKing is the Amendment 64 Security Camera Authority. We have carefully gone over Article XVIII, Section 16, otherwise known as “Amendment 64” and we have helped numerous Marijuana Retail Shops and growers with their security camera requirements. The following is a reference of what you need to be compliant as well as additional information you might need.

The following is a reference of what you need to be compliant as well as additional information you might need.

Analog or High Definition Cameras

While there are no stated minimum requirements for your security camera system needed for your Marijuana Retail establishment, we wanted to show you the difference between what an analog camera will provide versus a High Definition Security Camera. Both formats will get your inspection passed. Both can record on to a security recorder and can be viewed anywhere in the world you have Internet. Both will potentially deter criminals just for the reason that they will see the cameras and go on to the next store.

However, if you do ever have criminal activity, you would want to be sure you have the best recording possible. The difference is in the detail the camera will capture. The video from an analog camera will distort, or pixelate, when trying to zoom in and see detail. Click on the link below for a side by side video comparison. 

Imagine if someone broke into your store and you presented your security camera footage to the authorities. Having High Definition Secuirty Cameras could mean the difference between an arrest, due to a positive ID, versus not being able to see any detail. This is why we suggest going with High Definition Secuirty cameras such as HD-CVI or IP. Sure, you could get along with Analog to get your inspection passed, but in the long run, just how much is your Marijuana investment worth. Besides outside theft, you need to keep an eye on your employees as well as your crops. HD Security Cameras can also be used to monitor the healthiness of your crops (if you are a grower).

40 Days of 24/7 Security Recording

By law, you are required to have a surveillance system that can record and hold 40 days of security footage recording 24 hours per day non-stop. In order to figure out how much disc space you need for your security camera system, we have created an Online Hard Drive Calculator to help you determine that. Below are two examples of how much disc space you would need for 16 cameras. One of the major differences between an Analog Security Camera System and a High Definition Security Camera System, besides the clarity of the video, is how much disc space is needed to hold information for the 40 days.

Hard Drive Space for Analog
Hard Drive Example for an Analog System
Hard Drive Space for High Definition
Hard Drive Example for a 2MP High Definition System
As you can see it is very important to determine how much hard drive memory you need before you make your purchase so you can prove that your security camera system can record footage for 40 days. It is always a good idea to get more than you need to be sure.

Creating a Site Plan

It is very important to develop a site plan for your Marijuana Store in Colorado or for your Marijuana Growing Facility. This way, we can help you determine exactly where your security cameras should be placed. All entrances and exits, sales areas, growing areas, windows, storage areas, etc. need to have 24/7 camera surveillance, and we are experts when it comes to placement and coverage. All you need to do is provide us with a layout (whether it is professionally done or just scratched out on a piece of paper), and we will assist you with what you need to get you surveillance system inspection passed. Having the cameras configured in the site plan will also make it easy for your installation process. If you do not have an installer and do not want to do the installation yourself, we can recommend one. If you are in the Denver area, we can take care of the installation through our install department.

The image below represents a typical site plan. This is not an actual plan as we do not make public our customer’s facilities. This is just an example, and chances are your site plan will be very different.

Securing Your DVR

According to Amendment 64, your security recorder needs to be secure and in an area where it can not be tampered with. We have the perfect solution for this. Our DVR Lockbox will hold any of our DVRs or NVRs and keep it secure. It locks with a key and has an internal fan to keep your recorder from overheating. You can mount it to a wall or shelf using our optional brackets. Marijuana Inspectors love seeing these units being used. There is no way your DVR can be messed with or stolen, and so the footage will always be available to the authorities if needed.

How to turn on and off an IP camera using Smart Devices | Getting more of your Smart Devices

Written By:
Monday, January 19th, 2015

smart bedroom


Many of you are installing cameras inside and outside of your homes and there are many times where you wish you could turn off your camera (at least the one in your bedroom) with the push of a button. Maybe by just giving a verbal command or simply pulling out your smart phone and using that to turn the camera. With “Smart”  items coming out for your home that are basically interconnected with your network, this is possible. I recently got a customer asking why there were no solutions to do this with his security system and after a brief pause I got a Eureka! moment. I figured that I already have some of these items and I can add them to my system. There are some items that you will need to accomplish this task. We are going to showcase some items that you will need and optional ones that will help you make your Home a Smart Home. Just follow this easy document on “How to turn on and off an IP camera using smart devices”

Items that you will need:

Single port Power Over Ethernet Switch POE-1G



Belkin WeMo Insight Switch


ivee – Sleek Voice-Activated Smart Clock [Optional for voice Command]



The main items would be a Single port PoE Switch POE-1G which will power the camera via an Ethernet cable and that would get connected to a Wemo Insight Switch.

The Belkin WeMo Smart Switch communicates with your  IOS or Android Device to turn the power on any 15 amp 120V AC device on or off. This can be used to to control lamps, Christmas lights or anything that will use a 120VAC power source. We will be connecting the PoE single port switch to this device allowing us to power the device or turn it off, but I always like to push things even further. Why not add a Siri like device to operate not just this but any other Belkin WeMo Switch or Nest Thermostat devices? Well for this we need a device called ivee which doubles as a Smart Clock that connects to any smart device. I found myself needing to change my alarm from time to time and found this smart clock that also allowed me to turn up or down my temperature using my Nest Thermostat as well as turn on of off the lamps or even open or close my front door making my life a little bit easier since in times I forgot if I set my alarm correctly and also if my front door dead bolt was in the locked position, a simple command to the ivee from the comfort of my bed allows me to do this as well as allow me to turn off the camera in my bedroom when I decide I need some privacy.

There are so many things that can be done with this type of device that people do not realize it. For example you can add a command to enable one of these Smart Switches and on this smart switch you can have a relay that will accept any high or low voltage device, lets say you want to turn off a non smart device such as a fan. If you are a techie you can have this device restart a router or any network device that does not have the ability to be accessed or the manufacturer failed to add a shutdown feature to it.


One big project that I will be integrating this would be to add this as Do it Yourself Pet Feeder where I will be ordering one of these and dismantle it and use it to operate a stepper motor that will have an auger drill with a hopper that will have a “V” shape. This will enable me to command Ivee to feed my cats in the morning while I get ready to go to work relieving from doing so as well as giving me the ability to feed them once I get home.


This gentleman here has a Feeder for his fishes, You can see how it works. You have a drill that will be used as an auger and a hopper that will have the feed. You can time the feed for my cats I would say 3 minutes or so for each cat once it has does its thing it should turn off , a simple time that resets itself should do the trick for this now keep in mind that for indoors you need to enclose this device so that any children or pets do not mess with the device since it does power using alternate current. As well as adding fuses to protect the circuit.




Smart Home Devices should not only allow you to enjoy Media but assist you with the smaller tasks that take so much of your time. Having these devices will enable you to view you home from anywhere in the world, open or close your front door when ever you wish to do so, like when you are at work and all of a sudden something breaks in your home there is no longer a need to call in off because you need your washing machine fixed , you can simply have the Handy Man work on the washing machine while you view him or her on your Surveillance system and allow him entry using your Smart Lock. Since I have cameras all over my interior and exterior I can monitor anything that happens in my home as well as allow anyone entry. Another example is if you are renting your Home or Apartment,there are times where landlords do not know they are not allowed into your apartment or home, knowing if your landlord is coming and going at times they are not allowed will help you in a situation where the landlord or any individual has entered without your consent.

So next time you are buying or have an item laying around look at what else you can do not just what the manufacturer designed it for, Keep in mind that these and any hack can lead to voiding your warranty but if you are aware of this and the item is already out of warranty go ahead and learn , Trust me you will enjoy it. One big example is when I helped a Customer use an Auto tracking IP camera to track deer and other wild animals in here property and have the video footage go to her webpage as well as her Youtube account. She was happy with her setup as well as I was happy after I had completed this task. 😉



Some Not So Obvious Things to Consider, When Choosing a Security Camera System

Covert or Overt?

governmental, personal and commercial security
When it comes to governmental, personal and commercial security, one might wonder, is it better to be Covert or Overt.
In other words is it better for a cop to sit hidden on the side of the road waiting to catch someone speeding, or would it be more advantageous to wait in plain sight, sporting a bright orange police car that could be seen from miles away?

Is it better to catch a person who committed a crime or prevent the crime from happening in the first place?


  1. Not openly acknowledged or displayed.
    “covert operations against the dictatorship”
    synonyms: secret, furtive, clandestine, surreptitious, stealthy, cloak-and-dagger,hole-and-corner, backstairs, backroom, hidden, under-the-table,concealed, private, undercover, underground;


  1. Done or shown openly; plainly or readily apparent, not secret or hidden.
    “an overt act of aggression”
    synonyms: undisguised, unconcealed, plain (to see), clear, apparent, conspicuous, obvious, noticeable, manifest, patent, open, blatant;

This is something you might want to consider when choosing your CCTV security system and cameras.

Do you want the cameras to be noticeable? That might make potential criminals think twice and hopefully deter them compliably before even committing a crime?

Do you want your cameras to be inconspicuous or even totally hidden?

scary cam bot
There are arguments for both, but it really depends on what you are trying to achieve.

Many people like for their security cameras to be very visible or overt. They believe that the noticeable presents of the cameras, is the first level of their security system, and will aid in preventing a possible theft or vandalism.

Although there are many styles of cameras available today, some people prefer to choose cameras with a very “Traditional Security Camera” look. This is usually a good option for retail stores or marketplace type businesses.

A good example of an overt security camera is the OB-EF700IR100L2812D-W Varifocal Bullet Security Camera sold by

On the other hand there are people who are not only concerned with security, but the aesthetics of the cameras. This may be the case if you are a home owner or the proprietor of a business that caters to luxury, like a fancy boutique or restaurant.

In cases like this one may choose a more sleek and covert security camera like the 1.3 Megapixel IP Network Indoor Dome by Tech Pro Security Products.

Another situation may be when you are not necessarily trying to prevent a crime, but one where you absolutely want to catch someone RED handed. Maybe that sneaky babysitter or catching you’re cheating husband! If so you might need a hidden security camera. These are cameras that are totally hidden from view or disguised as other items completely.

Popular models may look like, smoke detectors, motion detectors or even a stuffed animal like the popular, teddy bear security camera. Here are a few more that you might find interesting.

Should You Just Fake It?

Maybe you are the type of person that feels a deterrent is good enough, or you just don’t have the cash for a full blown security system. Don’t fret, you have another option. You can get fake or dummy security cameras.

At first you might think this is a ridiculous idea, but think about it. You could give the appearance of being protected by security cameras, for a fraction of what it would cost for a full (working) security system. On top of that, installation is a snap.


  1. a thing that is not genuine; a forgery or sham.
    “the painting was a fake”

    synonyms: forgery, counterfeit, copy, pirate(d) copy, sham, fraud, hoax, imitation, mock-up, dummy, reproduction;

Should I Hide My DVR or Even Lock It Up?

Another thing you might want to think about is the placement of your DVR (digital video recorder) or NVR (network video recorder).
Most people might say, that’s easy, I will just put it near the rest of my electronics or in a place that is easily accessible.

lockdown security DVR

If you using your cameras to keep an eye on the kids, or see who’s at the front door, that might be fine. But think about this, what good is catching a thief on camera if he decides to steal your DVR/NVR along with your brand new, 60″ LED smart TV? No recorder, no way to review the recorder video.

For this reason many people prefer to keep their recorder in an inconspicuous place, like in a bedroom closet on the top self. Another option is to use a lockbox. DVR or NVR lockboxes are exactly that, a metal box that encases your recorder. They can be locked and permanently mounted. This will ensure that the recorder cannot be easily stolen or tampered with. Both the lockboxes and mounting brackets can be found on

How will I view my Live or Recorded Video?

Many of the newer model recorders have VGA, HDMI and BNC video outputs built-in. You can simply hook up a monitor directly to the unit as you would any standard computer or laptop.

As a matter of fact this is the most common method used for the initial setup of the recorder. Once the setup is complete, you may want to leave the monitor connected. Then you will just manage the recorder or view your live or recorded video directly at the unit.

If your recorder has a network card and supports remote viewing, you can also disconnect the monitor and view or manage it remotely. All TechPro Security Products DVRs and NVRs have several options for remote viewing.

These options include using a web browser on your computer or laptop, as well as being able to use mobile devices such as iPhones, iPads, Android phones and tablets.


As you can see when choosing a security camera system, there are several factors to consider beyond just the basics. With a little extra thought and planning, you will be sure to choose a solution that will fit your needs for the long term.

A Common Sense Guide to Buying Security System Cameras

A Common Sense Guide to

Buying Security System Cameras

A Common Sense Guide to Buying Security System Cameras by Matt          Today’s security market is going crazy!  People are scrambling to protect themselves, their families, possessions, businesses, etc.  The economy has created a whole new wave of crime and out of control is only the start of the description of what’s going wrong.  This craze has in turn created a new type, style, and breed of consumer.  Oblivious, and its not their fault.  Most retailers confuse the average guy or girl so badly that “up” isn’t even a direction anymore.  Well, I’m going to sort all of that out for you.  By the time you’ve gotten through this brief read, you’ll be armed to the teeth with information that your average reseller isn’t even going to have.  Let’s get into it!

First things first:  TVL…  Television lines…  The grandaddy of bull.  I always hear people talking about it.  “My cam has 500TVL”  “My cam has 700TVL”  “My cam has 1,583,295TVL”   blah blah blah…. Who cares?  Ya, that’s right…  LA DI DA….  six bazillion TVL….  Who freakin cares?   What’s a TVL?  Why do you even care?  NO…  IT IS NOT REALLY RELEVANT.  Just stop…   Recorders can’t take advantage of ANYTHING over 480TVL.  That’s right 480…  you’re neighbor who’s clamouring over his brand new $8,000 1.65 gazillion TVL cams; he’s an idiot (and has probably been raked over the coals by a security company looking to make a quick buck).  Only until recently, most recorders couldn’t even record over 240TVL.  480!  That’s your magic #.  Anything over that, means NADA.  The only exception is High Definition, and they don’t measure that in TVL.

So now that I’ve pooped on your parade route about what you THOUGHT was important, let me bring you up to speed on what is ACTUALLY important: Chips, lenses, housings, illumination, features, and control.  These factors are what you need to be paying attention to.  This difference between cameras is great.  Not simple.  To decide what camera is best for you, you must first understand what you expect of the camera.  Do a thorough survey of each of your camera’s potential location on your site.  Know what you expect for the cam, and then start your research.  Also understand that cameras DO NOT work miracles.  If your recorder sucks…  No camera in the world will make it better.  In addition to that; cameras do NOT increase your recorded resolution.  If you like the way your picture looks when its small, and you hate the way it looks when you go full screen…  DO NOT waste your money upgrading your cameras.  That is your recorder that you’re not happy with.  On the other hand: If you’re not crazy about something in the image no matter how big or small (blurry, unclear, fuzzy, too dark, too bright, wrong colors, glare, etc etc etc), then you are looking at new cameras to make it better.  I call it “test your resolution”.  This small intelligent test could save you from blowing some major cash.

So now you’ve decided that you need to upgrade your cams, or perhaps its a completely new install and you want to make sure you buy the right thing.  Where do you start?  For me, its the physical requirements.  Are you mounting to a wall?  A soffit?  A Pole?  Having the most awesome dome cameras does you no good at all if they are blocked by a fascia board or you have to crank them to a perfect ninety degrees and get Infrared reflection in the view from it.  Housings do make a difference, but its completely from the install point of view.  Choose a camera design that works with your application first.  Then you can worry about everything else.

Once you have a housing and mount style in mind, you can then begin to consider what it is that you need, and the quality levels you are willing to pay for.  Yes, that makes a difference.  Lets get real here.  I’m always hearing someone tell me that they want to capture a license plate on a moving car from 50 feet away, but they only want to spend $1000.  Get real people.  You buying a multi-camera system.  You want it to produce CSI like results for under the price of one cameras they used to shoot the program.  Not to mention, not even those cameras do that. If you’re shooting a long wide area, and you want to be able to zoom in on the pic, be prepared to spend some cash.  You need a high resolution camera (megapixel) with amazing clarity and shutter speeds.  If you’re not prepared to spend thousands on your system then don’t even bother thinking that way.  That kind of technology exists, but its expensive.

If you want anything more than an overview camera to see what’s going on in a area, your best bet is to talk to someone that knows how to get it done.  You could fiddle faddle around guessing and adjusting and buying dozens of cameras trying to get it right, or you could just talk to someone that knows.  Yes, learning about cameras DOES help…  But until you get the thing into your hands and play with it, you’ll never really know.  Every company claims their product is the best.   Get on the line with them and ask them why.  If they seem like they’re mumble-bumbling and spewing vague bullcrap, they probably aren’t qualified to help you.  Its the guy that actually says something like “we use only the top components in our equipment” and can name what that is and why its so awesome that you want to talk to.

If you’re still bent on doing it yourself, here are a few factors that will actually make a difference:  Super WDR/True WDR (or 3DNR, or DWDR, in that order important), Super ATR (or standard ATR), megapixel lenses (which are relative to clarity, not image resolution), warranty length, infrared distance, motorized mounts, user-controlled on screen display, white balance, shutter speed adjustment, lowlight enhancements, headlight compensation, etc.  Features and capabilities are what make a high end camera worth it, not resolution (or TVL).  The trick is to understand what you expect the camera to do, and find one with the features that will enhance the situation.  Its fairly obvious that headlight compensation is not going to be very useful in a basement cam, nor will wide dynamic range glare resistance outdoors overviewing a field.

In essence, if you just look past “the easy route” and do a little research into what you are buying, and the individual features of the camera, you should really be able to do a fantastic job finding the right cameras for your situation.  Spending time learning the equipment will pay off big.  Finding self help videos is also a great way to see what a product is all about.  Remember to test a salesman for the basics before taking his word on the advanced, and if they really know the product don’t be afraid to take their advice.  They most likely know it better than you do.  A good salesman will be more than glad to let you know when you’re over buying, and that’s critical.  If you’re going to spend money on something you don’t need, chances are there’s something you DO need that you aren’t spending on.  The perfect camera system is a balanced camera system.


Understanding FPS and Resolution Sizes and What They Mean for You

FPS and ResolutionUnderstanding FPS and Resolution Sizes and What They Mean for You

Let’s delve into the world of resolutions and the pixels that they consist of. First what do you know (or understand) what a picture is? I’m sure you’ve been inundated with the term of “1080P”. Or “10 Mega Pixel on the go everyday activity camera” but do you really understand why this is so? Now that I have you questioning yourself, do you wonder if these terms truly mean and represent a higher standard of quality youre hyped to expect? Let’s begin with trying to grasp how our quality comes into play, it’s known as PAR (Pixel aspect ratio). It is a mathematical ratio that describes how the width of a pixel in a digital image compares to the height of that pixel (Very similar to square feet in units of measurements for buildings). There are a number of articles and tutorials online about this subject. To make the matter even worse there is a complicity of the PAR/DAR/SAR terminology but I will try to present the problem as simply as possible, and in regards to display monitors and DVR exporting instead of motion film cameras. After all, were all here to obtain knowledge in our security devices and how to choose wisely.

Most digital imaging systems display an image as a grid of tiny, square pixels. The ratio of the width to the height of an image is known as the aspect ratio, or more precisely the DAR (Display Aspect Ratio). The aspect ratio of the image as displayed, for TV, DAR is traditionally 4:3 (both analog and digital). There are several complicating factors in understanding PAR, particularly as it pertains to digitization of analog video:

Analog video does not have pixels, but rather scan lines, and thus has a well-defined vertical resolution (the lines of the scan) but not a well-defined horizontal resolution, since each line is an analog signal. Because of the over scan, some of the lines at the top and bottom of the image are not visible, as are some of the possible imaging on the left and right. Also, the resolution may be rounded (NTSC uses 480 lines). As well, analog video signals are interlaced – each image (frame) is sent as two “fields”, each with half the lines. Thus pixels are either twice as tall as they would be without interlacing, or the image is deinterlace. So, in a nutshell, aspect ratios allow you to “stretch” videos during playback using that aspect ratio number as a guidance as to how much the video should be stretched. For example, both the NTSC Standard 4:3 and NTSC Widescreen 16:9 resolutions are 720×480. For PAL both are 720×576. What’s different between Standard and Widescreen is the pixel aspect ratio regarding their horizontal size. On NTSC for example, the DV Widescreen aspect ratio is set by the DV consortium as 1.2121. If you take NTSC resolution of 720×480 and you do a 720*1.2121 you will end up with a number that’s 873 (872.712 actually). And that’s the actual rendered resolution of the DV Widescreen on a PC monitor: 873×480. That’s how many pixels of your screen will be used to display your DV footage, even if the actual resolution that was shot by the camera was 720×480. The Europeans (who use PAL) are a bit luckier, they have higher resolutions (720×576) and different aspect ratios.

Are you guys still with me? If so here’s the part you probably came here for (or eagerly waiting for).

There are a TON of Digital Video Recorders out there. A lot still peddling inconsistent qualities demanded by today’s consumers. I think of a lot of them as the old cliché term “wolves in sheep’s clothing”. So many devices advertised in either a false terminology or deceptive venue of capabilities. There is some confusion in the naming of high-quality video resolutions used by several video surveillance systems on the market. This confusion has allowed less-than- scrupulous system designers to fool unsuspecting customers. Here’s what you want to understand while weeding through these false prophets.

Allow me to denounce a specific misconception (these numbers are for NTSC video):

  • D1 is not the same as 4CIF
  • D1 is an aspect ratio of 720×480 pixels
  • 4CIF is 704×480 pixels
  • 2DCIF is not the same as 4CIF
  • DCIF is 528×320 pixels
  • 4CIF is 704×480 pixels

Specifically, DCIF is the same number of pixels (168,960) as 2CIF, but 2CIF is stretched horizontally. Now there is 960H which is a new standard for security cameras and security DVRs that provides high resolution images using advanced image sensors. Security cameras capable of 960H produce an image that is 960 horizontal and 480 vertical pixels large (960×480). OK now, lets review:

  • 960H is 960×480 pixels
  • D1 is 720×480 pixels
  • 4CIF is 704×480 pixels
  • DCIF is 528×320 pixels
  • 2CIF is 704×240 pixels
  • CIF is 352×240 pixels
  • QCIF is 176×120 pixels

FPS (Frames Per Second)

Frame rate (also known as frame frequency) is the frequency (rate) at which an imaging device produces consecutive images called frames. The term applies across the board for film, video cameras, computer graphics, and motion capture systems. Frame rate is most often expressed as FPS (frames per second) and is also expressed in progressive scan monitors as hertz (Hz).

30p is a progressive format and produces video at 30 frames per second. Progressive (non-interlaced) scanning mimics a film cameras frame-by-frame image capture. To the human eye this is known as REAL-TIME. There are a lot of variation of ways of presenting these numbers, many of which are misleading (Like our US Government system about taxes and national debt). Remembering that 30 frames per second is real-time, but that is for a single video stream. So let’s say you wanted to accommodate 4 cameras simultaneously, all in real-time, you need 120 frames per second available and its full unshared resources. To delve even further you have to question at what resolution is the real time image being displayed. Many systems can only record real-time if the resolution is lowered. With this new found knowledge, do you want to sacrifice frames over quality or vice versa? I wouldn’t!!! It’s much simpler to find and procure a system that can accomplish both simultaneously. To reiterate, let’s review:

One thing you need to be careful about when analyzing specifications of a DVR with respect to “frames”, “fields” or “images” per second capabilities is what do they all mean and how they are relevant in your pursuit of quality:

  • The total number of frames/images per second for the entire card to be spread across all cameras (cumulative total)
  • The total number of frames for each individual channel
  • The maximum frame capacity of the hardware not taking into account software switching, simultaneous functions, etc. (rated hardware capacity)
  • Display speed
  • Recording speed
  • “I” frame or “P” frame calculation
  • A combination of all of the above

Ask yourself, Is it really images or are they even calculating frames which also provides misleading figures. The frame rate issue is a very tricky one. The fact is the speeds that manufacturers quote are usually the “maximum” obtainable, meaning under ideal conditions, and does not take into account anything else the DVR, software, or video card might be doing. To add further to the confusion are some manufacturer quotes “IPS” (image per second) and “FPS” (frames per second). Why do they do this? Because 2IPS=1FPS. Therefore, in another math quotation, it takes 60IPS to equal 30FPS or a single real-time image. It becomes more convoluted because in “images” per second there are “initial” frames and subsequent frames which refresh only changed portions of the image. The DVR’s video card “captures” the image and records video, but what plays back and displays the video on the screen? The answer is the video card. Even though it is “capturing” (encoding) the video, it also handles the video display on the card (the decoding process).

I hope I was intuitive and insightful in this matter. Until next time guys, stay awesome.
