Our company, SecuirtyCameraKing.com, has been doing a considerable amount of business with Washington State’s I-502 applicants, and it has been a very beneficial relationship for both parties. Once these customers send us a floor plan diagram for the location they are trying to get licensed, we offer a recommended surveillance camera layout and then build them two quotes based on that suggested layout. This way we can make sure that the applicant gets the required video coverage and let them choose which type of system works best for them.

The two quotes that we offer as part of this service are for two different types of security camera systems which will meet the legal requirements in Colorado and Washington State. Each of these systems has its own strengths and a fairly equal number of them have been sold to several participants in this industry who have passed their final inspection and are now licensed.

- The first type of compliant system works with analog cameras. It’s the closed circuit TV technology that has been around for decades. Over the years this technology has been improved to the extent that it has pretty much reached the limit of the quality it can provide. This type of system meets the legal requirement because our analog DVRs are accessible through the internet and you can see the live feeds and recorded footage from each of the cameras. This is the least expensive type of surveillance camera system available today.

- The second type of security camera system which will meet the legal requirements uses IP cameras. This type of system offers megapixel quality video. Depending on the type of camera used with this technology, it can easily provide the highest resolution available in the security camera industry. Although this type of system costs a bit more, the reason is readily apparent when you see the difference in video quality.

We are proud to say that every one of our customers that have implemented our suggested camera layouts have successfully passed their final inspection and qualified for their license to grow, process or sell marijuana. The people involved in this burgeoning industry are spending a substantial amount of money in order to get their business off the ground and we take our part in helping them through this process very seriously.

When Colorado first legalized recreational cannabis our service wasn’t in as high demand because it had an established medical marijuana industry in place previously and the businesses involved already had the required video surveillance. However as this industry continues to grow, new applicants need to address this requirement for getting licensed and that’s where we come in to the picture in an expanded role.

We have been helping our I-502 customers to better understand the portions of the law which pertain to video surveillance, to the extent that we have even been working directly with the Washington State Liquor Control Board in order to help clarify the law. We have also done extensive research on Colorado’s Amendment 64 in order to be certain that we’re also able to help the applicants there qualify for their license and remain compliant in order to keep it.

Many of our customers in this industry come to us with the mindset that they are just getting a security camera system because they are forced to by the law. A smaller portion of these customers understand how a CCTV system can help with the security of their property and product. There is a less obvious potential application for a surveillance system in this type of situation – it can actually be valuable in helping to produce a high quality product consistently.

Once a customer has one of our DVRs or NVRs connected to that same router where they have a computer connected, then they can call our tech support team for help with the networking. The tech will be able to remotely log into the customer’s computer in order to get everything set up. After that process is completed the customer will be shown how they can remotely access their camera system from any computer in the world, iPhone or Android smart phones and/or a tablet based on the Android or Apple operating systems from anywhere in the world. Our tech support team is proficient at helping to get this set up and have done so for any customers that want to make use of this feature, regardless of the customer’s networking knowledge. The obvious application of this feature is to be able check on the security at the installation location. This is one of the features that can also help to grow a better product.

If megapixel cameras are installed at a grow location then the high resolution video will allow you to be able monitor the development of the plants during all of the growth cycles and under different circumstances. You’ll be able to notice changes in the plants which aren’t readily apparent when you have daily contact with them, by reviewing daily segments of recorded video over an extended period of time. In this way you can further monitor and evaluate how the plants react when you try different soils or soil substances, water levels, nutrient systems, PH levels, lighting cycles, growing temperatures, clipping frequency, and clipping style in order to optimize quality and production.

Many of the serious problems that marijuana plants can experience will leave visible signs. By remotely viewing your cameras from your preferred device every once in a while you’ll be able to monitor your plants for some of the more severe problems that they can face and be able to potentially correct the issue quickly enough to minimize damage to the crops. With a high resolution camera you’ll be able to monitor your crop for signs of being stressed (possibly triggering a sex change), nutrient deficiency, fungus gnats, spider mites, whiteflies, white powdery mildew, white powdery mold, and/or aphids without even being in the same state or country. Below are some images of the early signs that your crops are about to face some serious problems. These are just a few of the problems that have visible warning signs.

The ability to detect and avoid these potentially catastrophic problems early can be a key part of making sure that your business stays profitable. If you need to be away from the growing facility for a family emergency or you just need a vacation, being able to remotely monitor the crops means that you can have peace of mind even though you are unable to be hands on with your plants.

What are Varifocal Cameras and Varifocal Lenses?

Written By:

700 TVL Outdoor Varifocal Bullet Security Camera

So you’re looking for the right cameras to purchase when setting up your home or business surveillance system, and you begin to see all these different terms of tech talk. You wonder to yourself, “What are Varifocal Cameras and Varifocal Lenses?” It’s actually pretty simple to understand but finding the right one for each one of your scenarios may prove to be a bit more difficult. However, with this article, it doesn’t have to be! I will try my best to explain all of the details of Varifocal Cameras and Varifocal Lenses starting with the meaning of a lens or camera being Varifocal and why you would need a Varifocal camera or lens. I will also discuss some of the different lengths of Varifocal available, and then help you understand the basics so that you can decide when to use one, whether or not you’ll need it over a fixed lens, and how to choose the right Varifocal lens for your security system if you decide it’s the right choice for you.

A Varifocal camera will allow you to adjust the lens to different zoom lengths and focal points. The word comes from Variable and Focal combined. Variable meaning that the value can change within the scope given, and focal meaning the focal point or length of the objects in the scene that you are capturing with your surveillance camera. Another easy way to explain it that most people understand right away is comparing it to a digital SLR camera. You can manually rotate the zoom ring on the lens in order to get a closer cropped shot of your subjects and then you may manually adjust the focal ring in order to put that object or person into more of a clear perspective. Normally a DSLR Lens will allow you to set the auto focus but most Varifocal security cameras are going to be fully manual so that you can set the lens to the correct zoom and focal point and then leave it that way after mounting the camera and setting it up in the location of your choice. Also, these Varifocal lenses are not interchangeable like they are on a digital SLR camera. So when you purchase your Varifocal camera, you will have a choice of different focal points and zooms depending on how many millimeters are listed on the lens. Normally, you’ll see something like “2.8-12mm Varifocal Lens” on the description of a camera. This means that you’ll have the choice of setting the lens at a distance anywhere from 2.8mm to 12mm away from the camera’s image sensor where the image is formed. When you have the lens set to 2.8mm there is also going to be 2.8mm distance between the lens and the front of the camera where the light is focusing.

“Why would I need a Varifocal Camera or Varifocal Lens,” you ask yourself. Well, there are a few reasons that come to mind. First, having a Varifocal camera will give you a ton of flexibility when deciding on where to mount the camera and will allow you to have the option to move the camera later to almost anywhere you decide to put it. A Varifocal lens will give you the option to shoot down a drive way by zooming in all the way if you decide you just want to have a camera fixed on your new sports car. Or maybe you want to put a camera in a small room, and a fixed lens is not allowing you to capture everything you would like in that space. A lot of the times Varifocal lenses are rated at 2.8mm which is more of a wide angle view than the standard 3.6mm lenses on most fixed lens cameras. When zoomed all the way out to 2.8mm you’ll have a viewing angle of about 109˚ horizontal, 82˚ vertical, and 136˚ of a diagonal view. If you would like to view all of your choices in camera viewing angle we have set up an awesome lens chart that lets you see all of the distances and angles for cameras with a 1/3” CCD Chip.

A Varifocal Camera and Varifocal Lenses are usually going to cost more than the standard fixed lenses, but most people prefer to have them because of the flexibility you’ll have. They are just as easy to install as the fixed lens cameras are, but the only extra thing you’ll have to set during installation will be the focal point of your lenses. Here are some images of Varifocal cameras so you can see the various ways to adjust them:

Box Cameras

Most of these types of cameras do not come with lenses. You can purchase the Varifocal lenses separately. These are normally c-mount lenses which you can choose the right one for your application. These are one of the only types of surveillance cameras which are flexible with allowing you to choose the correct Varifocal lens for your needs.

Megapixel Varifocal Lens

Even Megapixel IP Box Cameras will use varifocal cameras. However, you need to make sure to purchase the lens that is specifically made for this type of camera because the analog c-mount lenses will not work properly with the megapixel IP box cameras.

Varifocal Bullet Security Cameras

Bullet security cameras are also known as cylinder surveillance cameras and have a great design for easy mounting and weather resistance. They are normally the choice for cameras that are going to be mounted in a high out-of-reach area outside of a building. The varifocal lens on most of these cameras will allow you to zoom in close to get better detail on an area or you can keep it zoomed all the way out for a wide angle. The camera shown below have two large screws on the bottom for focusing and zooming. You may use a flat-head screw driver or a coin to set the varifocal on these models.

Varifocal Vandal Dome Security Cameras

Vandal domes are great for protecting your home or business. These vandal domes can be installed indoor or outdoor and have a weather and vandal resistant dome. They can usually take a decent amount of impact from a vandal and the way their enclosures are designed, most of them make it very difficult for anyone to adjust their settings once they are mounted. Some of the better built vandal domes have the Varifocal screws inside of their protective housing and a vandal would need to take apart the camera in order to mess around with the focus or digital on screen display (OSD) settings.

Last but certainly not least, there are some things to be aware of when shopping for cameras that have the ability to zoom and focus. There are Pan Tilt Zoom (PTZ) cameras available too which have optical lenses that are capable of zooming in and out and auto-focusing paired along with a motor that will pan the camera up, down, left and right in order to capture a full 360˚ view around the camera. These cameras are usually at least double the price of what you can get a Varifocal lens camera for, and depending on the application, a PTZ camera may be overkill. Many people may think that it’d be fun to have a PTZ to play around with but the reality is that it may not be needed. Also, you’ll need to have a DVR which has the ability to remotely control the camera, otherwise you’ll also need to spend extra money on a controller. Also note that the image sensor size on the camera will affect the view. If you test with the same exact lens, a camera with a larger image sensor will capture a wider viewing angle and will capture even more light which is great for situations where you may have low light. Be careful and do some research when purchasing your camera because some manufacturers and resellers will list their camera with the wrong chip size. They may list the camera as having a 1/3 inch CCD when the reality is that they have a 1/4 inch. This will cause your view to have a much narrower viewing angle. The main thing to remember is that having a larger image sensor is going to not only be great in capturing more light, but also having a sharper image and more vibrant color saturation when compared to another camera which may have a small image sensor. Sometimes you’ll see a very large camera with a small image sensor, so do not judge the size of the camera and expect it to have a certain size sensor in it without doing the research first to make sure what you’re getting.

I hope that this article helped you in learning and choosing the right camera for you. If you have any questions or concerns, always feel free to leave a comment below and we will help you with anything you may need. We also have an awesome forum with techs that answer pretty quickly!

How to Configure a PTZ (Pan Tilt Zoom) Security Camera

Written By:
Tuesday, November 11th, 2014

Pan Tilt Zoom (PTZ) security cameras have become one of the more popular types of surveillance cameras that are on the market today. There are many different types of security cameras available today which can fill a wide range of the roles that their owners can ask of them. Even with the wide variety of cameras today, PTZ cameras are arguably the most versatile security camera that you can find. This article will go into how to configure a PTZ and what a PTZ can do.

The basic functions of this type of camera enable it to pan horizontally, tilt vertically and zoom in and out to various magnification levels. These cameras allow you to remotely control them from a DVR or over the Internet provided the DVR has been connected to a network. Depending on the particular camera, it can be zoomed in to a maximum zoom level of anywhere between 3x and 40x magnification mechanically. Some of the models of PTZ cameras will even have a digital zoom function built in to them that will extend this range of magnification. These PTZ functions allow the user to be able to log in to your DVR from a computer while away from the location where it is installed and take a look around. This can give you some extra peace of mind while you’re on vacation or just away from the location that you have protected with security cameras. You can also leave the camera pointing at whatever area is considered to be the most likely place for potential trouble.

Different models of these cameras can pretty much offer every feature that you can get in any other security camera in addition to a few that are only available on a PTZ camera. These cameras can include the ability to compensate for every conceivable lighting condition and be mounted to nearly any surface with an array of different types of mounts. Some of the features that are exclusive to PTZ cameras are the ability to automatically track a moving object, have a custom pattern which the camera will continuously follow and they can also be set up to return to a custom home position after a certain amount of inactivity. Many of the newer models of PTZ cameras that are available today will let you modify the settings for these features from the camera’s OSD (On Screen Display). Increasingly you can also adjust the settings for the basic functions of a PTZ camera through the OSD; these settings include the camera’s protocol, address and baud rate.

Installing a PTZ camera is a relatively simple matter that is only slightly more difficult than installing a fixed camera. The majority of these cameras have the standard wires and connectors for power and video transmission that all surveillance cameras have. They also have another pair of wires that either just have bare wire at the end or have a small post connected to the end. The purpose of these wires is to make it possible to establish control of the camera’s movement from the DVR. If you are installing one of these cameras you will need use a pair of wires from a CAT5 cable, 18/2 power wire or another similar cable to extend these wires back to the RS-485 connection at the DVR.

Here at SecurityCameraKing.com we carry several different models of PTZ cameras in order to suit your requirements and budget. Now we’re going to take a look at how to set up one of more popular models, the PTZ-LX700L12X-E, and access some of the features that this camera has built in to it. The first thing that you should do with any camera is test it by setting up completely while it’s un-mounted and close to the DVR. When you’re doing this it’s a good idea to get the camera to the point where you can see video on the DVR from it. In the case of a PTZ camera you should also get to the point where you can control the camera movement from the DVR.

When you take a PTZ-LX700L12X-E out of the box you’ll notice that there are four wires coming off of it. There is one for power, one for video transmission and two for establishing control of the camera (as shown in image 1).

PTZ Wires
Image 1

The power and BNC video connectors need to be hooked up in the same manner that you would use with most analog security cameras. When you first power a PTZ camera up you should see it automatically rotate though it’s range of motion. The two control wires will need to be extended so that they will reach the RS-485 port in the back of the DVR. If you are connecting this camera to one of our DVRs then the positive control wire will need to be connected to the “A” slot in the RS-485 and the negative control wire will need to be connected to the “B” slot of the same terminal. This type of physical set up is pretty common for the installation of most PTZ cameras.

It’s a good idea to connect the power to the camera last. Once this camera powers up you will see some information about it displayed over the camera’s view at the DVR. There are three parts of this data that will be useful in the initial setup – the protocol that the camera is set for, the camera’s current address, and the baud rate that camera is set up to use (as shown in image 2). This list of information will also tell you two ways that you can access the camera’s OSD through the DVR – by hitting the plus iris button or entering preset 95 from the PTZ control interface of our DVRs. You won’t need to get into the OSD for the initial set up unless you need to change the protocol, baudrate or address of the camera.

PTZ Baud Rate Settings
Image 2

Once you have the camera connected correctly you will need to make some setting changes in the DVR in order to be able to establish control of the PTZ camera. When you are in front of the DVR this is done by right clicking anywhere on the screen, then select Main Menu. Once you’re on the Main Menu, click on the setting button and then the pan/tilt/zoom button.
It’s important to realize that there is a different version of this page for channel that your DVR has. The first thing that you should do on this page is select the channel where your PTZ camera is connected. Next you will need to set the protocol, baudrate or address of the camera. The will be the same information that was provided on the information screen when you first powered the camera up (as shown in image 2). You will not need to make any changes to the data bit, stop bits or parity settings.

At this point you should be able to control the camera from the DVR’s PTZ interface. To get to this interface you will need to start with just your live camera views on screen with no menus being displayed. Then you right click anywhere on the screen and select pan/tilt/zoom from the small menu that appears. This will bring the PTZ control interface, which has eight outward facing arrows that is arranged in a circular pattern. This is also the menu that allows you to access the camera’s OSD.

Monitoring Gun Safety with Security Cameras

Monitoring Gun Safety

Let’s face it. Gun safety is an absolute must. Whether it is a standard .40 caliber handgun, or an assault rifle (AR) firing deadly .223 rounds down range, the need for proper use skills is monumentally important. Any range you may go to, there will be range officers on duty to help teach and protect everyone. However, the job of a Range Officer comes with great stress and responsibility, so it is impossible for them to see everything. This is why the use of security cameras inside the gun range is vital. The cameras will catch any misuse by shooters, whether it is dangerous or not, when the range officers happens to be elsewhere. This article I will explain some ways of monitoring gun safety with security cameras.

Shooting Range

I have had personal experience with these very scenarios of cameras catching misuse when the range officer has not. I grew up around a variety of firearms so I was introduced to proper handling at a very young age. But, with this particular incident, it was my first time at this gun range. My friends and I were welcomed into the range and debriefed about the rules that could vary from other ranges. We were told that we could have as many guns out at once, but that we could not walk a weapon out of its case from where we shot, to the benches behind us. I misunderstood and thought we had to leave them on the benches, open them, and walk them uncased to the firing position. The range officer was in a different section of the range, so he did not witness our improper behavior. However, a separate employee came through the door and signaled me over to him. He explained what we had done wrong, and told us to grab our things and leave. He pointed to the little camera in the corner, indicating what had notified him of our misuse. After I explained that it had been a simply misunderstanding, he agreed to let us resume shooting.

Bullet Security CameraThe camera in the corner that the employee had referred to was, ironically enough, a “Bullet” camera. SecurityCameraKing.com offers several different types of Bullet cameras. Some particular Bullet cameras that would benefit a gun range would be the IP based, analog, or HD-CVI cameras. One of the most suitable cameras could possibly be the OB-LX700IR100L2812-W, as it is an outdoor, analog, Bullet camera with a varifocal lens. This would be an ideal choice for an outdoor pistol/rifle range that has over 25 lanes. This camera, along with several others, would greatly increase the safely levels of any range. Also, cameras are of high importance in the entrances of ranges, in order to detect anything and everything that steps through the door.

Gun SecurityWhen it comes to gun safety, a gun range is not the only place a camera is necessary. Here at SecurityCameraKing.com, we provide the Boca Raton Police Department with a great majority of their security systems. Envision a gun vault in a police station; this would have be to be monitored around the clock to ensure there would be no unidentified people stealing any of the weaponry. In order to increase the security even more, SecurityCameraKing.com offers explosion proof cameras. If an intruder was to try to blow off the doors to the vault, the cameras would still be fully functional and all video evidence would not be lost. These explosion cameras exist on securitycamermaking.com, as the Explosion Proof PTZ Surveillance Camera With Wiper. The wiper accessory on the camera is great, as it will wipe away any debris that might happen upon the camera.

Gun SafeHome owners that own their own gun safe or gun cabinet should most definitely consider this as well. Just because they are locked does not mean they are completely 100% safe from the family members that may or may not know where they are. To all the fathers out, there think about it. Yes the safe is locked, but say you were cleaning a gun used recently and go to the kitchen for a drink. God forbid your little girl or boy wander in and find what’s in daddy’s now open, and accessible gun safe. If you had a mini alert alarm on that door (also offered here at SecurityCameraKing.com) you would know when that little boy or girl walked in that room and you could prevent anything bad from happening. Also if you have a teenage kid and he/she likes to sneak off in the woods by the house and shoot random things, if there was an alarm contact on the door to the safe it could trigger your DVR to record and this is also a great way to utilize the TechProSS App for IPhone and Android.

TechProSS Apps

The second that alarm contact is triggered and the DVR begins to record, you could get an alert on your phone and now you know it is time to handle this situation. On the contrary, an IP-based camera system may be more effective, even though the app is a great tool to monitor home away from home. If you have an IP-based system you don’t even need the NVR. All you would need to do is have a monitor set up at work or wherever you spend most of your time while away from home and watch a live feed of all your cameras through the IP (Internet Protocol) address.

Those are few out of several ways Gun Safety can be monitored using security camera systems. Whichever you believe will work best in your benefit, I’m positive we can take care of you at SecurityCameraKing.com. Do yourself a favor and visit us online at www.securitycameraking.com to get started monitoring your gun safety.

Security Camera Comparisons

Written By:
Friday, November 7th, 2014

Security cameras are becoming significantly more prevalent in our society every day. This increase is due in part to the technology behind them getting better and better all of the time. As these improvements take place, the cost is also coming down at about the same rate. Because of all of these improvements in security camera technology there are far more types and styles available to the consumer today then every before and this variety can easily confuse even a tech-savvy buyer. In this article we’re going to take a look at the assortment of designs and features that are offered with some of the surveillance cameras on the market today and provide you with some useful information that should help you make the decision of which camera will work best for you. It will serve as a useful guide on security camera comparisons

That first thing that you should consider when you’re buying a security camera is whether it will be mounted outside or indoors. All security cameras are designed to work inside a structure but only a portion of them are designed to work outside, in the elements. Indoor cameras are usually less expensive, weigh less and are made with lighter materials. Surveillance cameras that are designed to be mounted outside are usually made of a stronger material, such as metal or a thick plastic, and sealed in such a way that they will keep moisture and debris out of the delicate internal electronic components to varying degrees. There is a rating system, called the IP code, which will help you determine what level of protection that a camera provides and allow you to choose the camera that will work best in the environment of your installation. This rating system is too complicated to explain in detail here but it’s a good idea to make sure that you use a camera that has an IP66 rating for outside installations. This means that the camera’s housing will protect the more delicate parts of the camera from dust and jets of water.

There are variations in the way that security cameras are built, both functional and aesthetic, that are a consideration when deciding what type of camera will work best for you. There are basically four different styles of cameras: box, bullet, dome and PTZ. There are a few differences in these types of cameras in the manner in which they can be mounted and where they can be installed.

A box camera is usually a rectangular camera that needs to have a separate lens attached to it. These lenses are available in a wide variety of zoom levels and are usually larger than those in other types of cameras. These larger lenses allow more light to be processed by the camera, resulting in a higher quality image. If box cameras are installed in an outside environment, they will also need to be mounted inside a housing to help protect them from the elements. These cameras are highly noticeable and because of this, they are effective in the role of a criminal deterrent as well as providing high quality video footage. The lenses for these cameras can be built with a varifocal lens, which means that you can manually adjust the level of zoom to suit your needs.

A bullet security camera is a surveillance camera that has an oblong or cylindrical shaped housing, which is fixed to the mounting surface by some sort of an arm. These cameras allow you to easily mount and adjust them to the desired field of view. Bullet cameras are often designed for indoor and outdoor installations, but it’s still a good idea to check the IP code rating if you’re planning to use them outside. Unlike box cameras, bullet cameras can be designed with infrared (IR) lights around the lens of the camera. This IR lighting is triggered with an internal light sensor, so that the camera will be switched to IR mode once the lighting levels drop below a certain point. Once the camera is in this mode it will be able to show video in complete darkness.

A dome camera has a bulbous shape to it and can be mounted on most flat surfaces. This design offers the highest level of vandal resistance, which means that these security cameras make it very hard for anyone to tamper with them after they’ve been mounted. This type of camera is also available with infrared lighting built in to it so that it doesn’t need a visual light source to be able to record video for you. Dome style cameras are available in models that are designed to be mounted indoors exclusively or models that can be mounted indoors or outside.

Another type of surveillance camera that is very popular these days is a called a Pan Tilt Zoom camera or PTZ. This type of camera allows you to get the camera to pan around horizontally, tilt up and down vertically, and zoom in and out. All of these abilities are controlled from the DVR or over the Internet depending on the type of DVR you have and how it’s configured. These cameras are available in indoor and outdoor versions with widely varying magnification levels that can include both mechanical and digital zoom functions. PTZ cameras offer you the ability to have a look around the area where it’s mounted while you’re away from it. Some of them even have an auto tracking feature which will let it follow movement automatically.

All of these styles of security cameras are available in two different signal standards that have been around for years – Analog and IP. There is also a third signal standard that has arrived on the scene recently that is called HD-CVI.
Analog cameras have been around the longest of the three types and are still the most common. These cameras have BNC connectors for video, and they can use a few different types of cables to connect them directly to a DVR and some form of power supply. BNC connectors are circular with two small posts that lock the connection in place.

IP cameras have also been around for years now, but they are still newer than analog cameras. They are connected to a network through a standard network cable, either a CAT5 or CAT6 cable. These cameras are capable of megapixel resolution but can put a stain on a network’s resources unless the network is designed to handle significant bandwidth or a separate network is built for multiple cameras of this type.

HD-CVI cameras are the newest type of signal standard. These cameras are capable of delivering megapixel quality video footage and the video signal doesn’t go through a network. The cameras for this type of security camera system use BNC connectors and RG59 to transmit the signal to a DVR specifically designed to work with this type of camera. You can learn more about this amazing technology and the specifics of what HDCVI is here.
