The Many Uses of Security Cameras

Written By:
Thursday, February 20th, 2014

Cameras have changed completely since their inception. Some of the first images were of a piece of paper with silver chloride. The images were mostly dark shadows with no real details. Nicephore Niepce was reported to be the first person to create those images. Unfortunately his “pictures” would become entirely dark over time. The entire process was very cumbersome. You would need special chemical baths for the film to be developed. This was all around 1786 unfortunately Nicephore Niepce did not live long enough to see the fruits of his labors. About twenty years later the Box camera came to light. Although cumbersome it did start to produce quality images for the time period. The severe downside was the exposure times are very long, 3 hours long to be precise. Through the 1900s cameras of this style were the norm. Most were limited in application.

As you can see these cameras need a serious stand built for them so they can be motionless during the exposure time, and whatever you are taking a picture of would need to be motionless as well. These cameras worked well for people when everything was going a little slower than today. Those pictures are a good fit for picture albums and other typeset print media, i.e. books and pamphlets.

Today cameras are all about where and what you can put them on or in. After a trip to the doctor’s office it is a little unnerving what they can now look at in full color. Cystoscopy is a test that looks at the inside of your bladder to determine if you have any urinary tack issues. Cystoscope is the instrument that is used. This picture is of an actual cytoscope:

This camera allows your doctor to look at what has been bothering you. Now this is as closed circuit Television as it gets. The video feed is piped directly to a monitor for the doctor to look at and any brave family members you have with you. A cytoscope is a water proof camera for obvious reasons, so it is great for wet environments.

Working Length: 370mm
Angulation: 210° Up & 150°Down
Field of View: 120°
Depth of Field: 3mm-50mm
CV-1.5 Insertion Tube OD:

(1.5mm Channel)
4.7mm x 5.4mm

These specs vary depending on where you get the camera scope from, but as you can see it is very small.

Another type of radical camera is a bronchoscope. It is designed to allow a doctor or physician to view the inside of your respiratory tract.

bronchoscope

Depending on the procedure the care provider will go through the patient’s nose or mouth. During the procedure the device will pass though the throat and into the airways of the person. The Scope itself consists of a camera with light attached. It is like your own camera crew only they are in your lungs. Once inside the camera can see any blockages or inflammation the patient maybe having an issue with.

As cameras have grown in popularity people have gone above and beyond as what they will put a camera on. The following picture is a novice that understands the importance of being able to record around their vehicle.

On a professional level UPS has found the need to place cameras on their delivery trucks. There are three main reasons for this straight from the UPS driver. The first and most obvious would be to prevent and track theft. The second reason is to help the driver to prevent getting into accidents. The third reason is to prevent general mayhem from people around the truck, such as people trying to hitch a ride on the back of the truck. Apparently it happens more than you or I would think. Almost weekly people are being booted from stealing a ride on the back of UPS trucks. That is about as bright as skitching a ride on a skateboard by hanging onto someone’s bumper.

Another great use for IP cameras is to use them on rental items such as quads or four wheel drive vehicles. I have a customer that has set up several rental business with IP dome cameras on their equipment and then they sell the video back to the customers too, so not only does it video of any negligence people can get a movie of the crazy stunts they probably were not supposed to be doing as well. Motor cross as a whole has been growing with more widespread use of helmet cams. Riders are now able to share their sick rides through the forests, the dunes, or on tracks. Before all of this was only seen with recording equipment that the television and cable networks had.

Nascar has taken cameras to the next level with putting them on the cars. Nascar has a service called “RaceBuddy” It is very cool if you are into racing. You get six video feeds from the driver. Next you get in and outside views off the car. Also you get the backstretch cam which is amazing being able to see the leader with everybody on his tail. Then you get video from the pit crews and pit road. This is all done over the internet so many users can be logged in to look at all the different camera shots. What makes RaceBuddy so innovative is how they use the video stream on a website. Any camera or DVR has a limit to how many users can log in at one time. Taking the RTSP stream to a webserver so only the webserver actually logs in then multiplies the feed to users on the website is brilliant. This method lets as many people to view without overloading your own network.

RaceBuddy

School busses and regular public transit has been installing more and more cameras for public safety. The installed cameras on busses help resolve differences between passenger and another passenger or issues with the bus driver. There is now a way to make sure the people on the bus and the operator all doing the right thing. This also helps the operator do some of the more important tasks like drive in heavy traffic not mediate a dispute between riders.

Not that our loving children are doing anything wrong on the bus while going to school, but it is always good to be sure especially in a court of law.

Cameras are getting smaller and smaller as the technology matures. From the medical field to racing, and law enforcement cameras are making every picture worth a 1000 words. The scope of a camera has changed from entertainment to tools of the trade and these tools are getting more precise as time goes on.

How to Setup a License Plate Capture Camera

TP-LP700 License Plate Capture Camera

I often get asked how to best capture a license plate from a vehicle with a camera system. I generally tell the customer that it is done with magical leprechauns, the tooth fairy, and a dash of pixie dust! Then when I get serious I will go into the long explanation of the proper setup to capture the image. With license plate capture there are several things that need to be considered and in place to be able to capture a license plate on a vehicle. You need to be between a certain height and angle, need to be focused on a concentrated area, need speed control of the vehicles, and need the proper camera.

The Right Height and Angle

With any camera, the right angle and height are very important when trying to achieve specific shots. A license plate capture camera is no different, and actually it is more important than most. There are several schools of thought as to what is the idea height and angles for this application. The one that I have found works the best, is to ensure the camera is between thirty six inches from the driveway up to ten feet. The height of the camera plays a big role in how clear the image will be, if the camera is too high and the vehicle has some sort of plate cover on it, you can get an image that is too distorted to make out.

If you think about it, most vehicle license plates are between twenty inches and forty eight inches from the driveway surface, so you don’t want to create a crazy angle to try and capture a license plate from. Another important thing to remember is how far off the lane of travel the camera is situated, this plays into the angle created on the capturing of the image. Typical rule of thumb is to have the camera as close to the lane of travel as possible. So the closer to the curb the better!  Now, I know you are asking yourself, “what if someone comes up and vandalizes the camera?” Well, the way to help protect this is by having a camera that watches over the location of the license plate capture camera.

Focused Area of View

Another big factor in license plate capture, is not trying to do everything with one camera. In order to properly capture a license plate, the camera needs to be focused on one lane of travel. So, if you are trying to capture multiple lanes of travel you will need as many cameras as lanes you are trying to capture. A good rule of thumb is to have a camera per lane and a camera that gives overviews of the area. The overview camera will give you the description of the vehicle, while the license plate capture camera will get the license plates. If you try to do too much with one camera you will fail at doing anything useful except get a description of the vehicle. It may cost you a little more upon initial setup for the extra camera, but what you will gain with useful information is priceless!

Speed Control

A very important factor to be considered is the speed the vehicle will be going. If you have a vehicle that is traveling at a high rate of speed and you expect to capture it’s license plate you better plan to spend some very very big dollars on a camera. Now if you are realistic and have an area where a vehicle has to slow down or even better stop, you will be in tall cotton. The most ideal way to capture a license plate from a vehicle is to have an area where the vehicle will have to come to a complete stop. Whether that is at a stop sign, a severe speed bump, or a gate that has to open does not matter, as long as you can get a vehicle to stop. The next best solution is where a vehicle has to slow down extremely, ideally under ten mile per hour or so. Now if you do not have the ability to slow the vehicles down, you are going to have to look into the cameras that most interstate systems use which generally cost in the thousands of dollars per camera.

Proper Camera

Barring needing a specialty high speed camera that interstate systems use, you can generally find a good camera with a reputable company. The right camera will depend on several things. The first and foremost is the distance from camera to target. Why this is so important is because you need the right lens to narrow down on your target. If you are at thirty feet and trying to use a 2.8mm – 12mm varifocal camera and narrow the shot down to a eight foot by eight foot area, you will fail. This is because at a thirty foot distance to target and the camera zoomed all the way to it’s 12mm setting, your area of view is going to be over ten foot by eight foot. This generally will be too wide of a shot to capture a clean enough image. I personally would suggest going with a 9mm – 22mm lens for anything over twenty feet to about forty five feet. For any shot that is from about fifteen feet to about one hundred and twenty five feet you should use a camera with a 6mm – 60mm lens. If you are unsure of the millimeter lens that you will need, you can always use the lens calculator on Security Camera King’s website.

If your project meets all of these requirements, your license plate capture should occur with minimal issues. With every job and every location there are different obstacles that will be needed to be overcome, no two jobs will ever be identical especially when it comes to license plate capture. The best thing you can do for yourself is to survey the area, taking lots of pictures and measurements. Find any possible available power source and possible areas to burry conduit to get to the camera location. Keep in mind to always obey local codes and pull the necessary permits. The last thing you want to have happen is an inspector/ code enforcement officer to flag the site and cost you time and money.

How to install a Home Security Camera System

home cctv security camera

Installing home security has been seen as an important field of action that uses technology to provide protection around a person’s home, while being controlled from tech support. These surveillance systems allow you to monitor your home and provide a safe environment for you and your family by using web browser on a computer or even a smart phone. The following is a brief listing of new ways that you are able to keep your home well guarded from different types of intruders.

There are many essential parts in a surveillance system. Some of theses include surveillance cameras, a DVR (digital video recorder), power supply, cables, and a monitor. The cameras are used to film areas that are under surveillance; however, the DVR is used to record footage and display live scenes through the monitor. The power supply, which is used to power the entire system, is connected to the digital video recorder. It is also possible to run the DVR through a power box and then connect the power supply to the box. There are many things that should be put in consideration when installing a surveillance system. However, one of the most important things someone should consider is the type of cameras that should be used.
If you are considering installing a video surveillance around your home, you should learn about the different types of cameras that would best fit any reason or situation you may have for possessing a surveillance system. There are a couple of features to consider when it comes to choosing from the variety of cameras for a surveillance system. The three main cameras choices that are most commonly selected include: dome cameras, bullet cameras, and box cameras. Dome cameras have low visibility, meaning they blend in well with their surroundings, and are always attached to ceilings. Bullet cameras are prominent and are obvious in their appearance as surveillance cameras.

After selecting which the appropriate type of camera, the next step is to choose where the cameras will be installed. Out door cameras would be in necessity of weather protection, but it is also possible to purchase waterproof surveillance cameras or protective camera housing. In indoor installation, cameras must be placed where they cannot be seen by other but still allow coverage of the area that needs watch. Bullet cameras are usually placed in corners of walls while dome cameras are less likely to be seen. After determining the areas where the cameras will be placed, the following step in installation.

Installation can be a complex process. It is a difficult process from setting up the wiring to placing the surveillance cameras in their position and the connection of all the equipment from the installation. Where you place the camera is important. The distance of the camera to the area you are focusing on should be given careful consideration and make sure it is clearly visible. You must make sure the camera is properly mounted so it will not shake or distort the picture or image.

For those worried about security, out door camera are suitable because they are used to prevent criminals from attempted robbery and break-ins. If you would want to know what happens while you are away, these surveillances may ease your mind. Video surveillance allowed you to monitor or record in personal areas. For example, parents may want to watch over their children while they are sleeping and lower risks of danger or even to catch a crime in your own front yard.

But before you install a security system in your home, you should be aware of the legal restrictions on video surveillance. If you are not aware of these legal aspects, you may potentially face charges. Knowing the laws of having a security system will lead us to finally installing the surveillance system.

It is important that the installation of the surveillance cameras is done properly. Poor installation will not get provide proper results you’ve hoped for. Some surveillance has motion detectors that activate once the gadget picks up any movement within the area.

Home security systems may be very complex and installation involves mounting. The alarm system is called a close circuit system. When doors or windows open, they trigger sound circuits because when closed wires are in wiring loops, opening breaks that loop causing those unsatisfying noises. Installing this means installing the sounder first. This alarm is used to scare away any intruder or to call attention for help. You must be sure that the mount is correctly mounted. We must know how to wire the system after mounting the alarm and installing the switches, fire sensors, and window foils. A knife or wire stripper is used to cut off ¾ of an inch of the wire ends. Then loop each wire under a different terminal screw on the switch. Run the wire to every entry detection switches and sensors. Then add the copper wires to the screws and twist together two silver wires. They should go in the sensors without breaks or interruptions.
To connect the sounder, use solder less connectors to join black wire from the battery to the sounder to make it operate correctly. Then connect the wire ends from the switch to smaller wires on the sounder. Test sounder after by opening the door or window. If it is correctly installed, the alarms should go off. Besides alarms, there are many more gadgets for security for your front door. For example, push-button locks allow you to lock and unlock using the Internet or a smart phone.

When installing the indoor cameras, you must follow the manufacturers. Bullet cameras generally need screws to be able to be hung on the wall, it is that simple. One the other hand, dome cameras require a perfectly cut circle from the ceiling where the camera is going to be placed. These systems involve whole home wiring. Video surveillance and 24/7 monitoring that carry many features.

Installing home security system helps raise awareness about your home’s security and often leads to people being able to lower the risk of a home break-in. It also teaches families about security and how to take control of the home environment.

Five Things to Consider for When Selecting a CCTV Camera System Component, Package, and Company

Five Things to Consider for When Selecting a Camera System Component, Package, and Company

When shopping for a security camera system, its very easy to fall into any of the traps set by good marketing and advertising. You have to navigate through oodles of jargon and flat out lies in order to even start your decision. Here’s a few ways to tell whether or not you’re getting a good system from a reputable company (and no. Just because a company is “big” doesn’t make it either a good system, or the makers/marketers any more reputable).

1) Tech Support. Quite possibly the biggest factor. It doesn’t matter how amazing the picture is, or the quality, or anything else. If the manufacturing company doesn’t offer accessible support, you’re eventually going to be very unhappy. All things technical eventually, if not immediately have an issue. You want to make certain that you can actually reach someone in the event of an issue. Make sure there is more than one method as well. You want options like email, forums, phone lines, and online resources. Perhaps even go as far as give it a test run. Pretend you’ve had an issue before you’ve even bought something. What are you going to do? Can you find email contacts? Are there frequently asked questions sections in their resources? Can you get through to tech support? Does anyone answer the phone numbers provided? If you have a problem at any point, you want to be able to get it resolved. Support contact is imperative.

2) Warranty. Actually, not just if it has one either. Warranties are only as good as their usefulness. Some warranties don’t actually cover anything. Also, some are flat unclaimable due to the fact that there is no one to contact if or when the system has an issue. If a company has two different warranties for two different products, there is most likely a reason for that. There are obviously differences between tiers of products. You really want a two to three year warranty if you can find one. Some companies offer five, six, seven, and rarely more years of coverage. Again, this could be because they stand behind their product, or it could be because they have no intention on being around when it comes to pay the piper. Be leary of excessive warranties. One or two years is the standard. Low voltage electronics are not designed to last this long due to the fact that they are typically out of date technically in under three years. Essentially; you’re most likely going to want to replace them in two to three years anyway.

3) Value. Bang for the buck. No one likes the feeling they get when they buy a system and find out next week it went on sale, got discontinued or closed out, or is comparable (if not exactly the same) as another system for less money. Contact the company selling the system and find out these things. Also find out what is actually inside the machine. There aren’t a lot of chip and processor companies out there. The likelihood that you can find the exact same components on the market in another housing is very very good. Don’t base your entire decision on this, but use it as a “tiebreaker”. Companies do not usually support products their competition have sold, even if they are exactly the same. Just because you got a great deal doesn’t guarantee your long term happiness. What I find to work (often) is simply ask the company you like more to meet/match the price. They most likely are already familiar with the competitor. They may not match it all the way, or be happy about doing it. But they will most likely give you a price that will at least satisfy your pocket.

4) Future-proof. This actually goes more for the infrastructure involved with your system components. Often people are concerned about how long their components will last, and not at all about the cables and connectors that are involved. You really must consider this element as critical. As technology gets phased out, it becomes scarce. IDE hard drives are an excellent example of this. This was the standard for years, and within a single year they pretty much disappeared to the successor (PCI). Now its nearly impossible to find them. This too is somewhat true of the cables involved. You may think “big deal, cables are cheap”. However, your time isn’t. Even worse if you need to pay someone else to do the work. Being able to use your cables for future systems is probably going to save you a bundle later. Try to choose a cable type that can be used for something other than cameras (like Cat 5 or Cat 6). This will increase the likelihood of you getting future usage from them.

5) Knowledge. This is another common sense factor that often gets overlooked. The market is full of importers and warehouses. Yes, you can most likely get a deal from them. However don’t forget to consider the amount you know about security camera systems. A discount computer is fine, due to the fact that you’ve most likely owned several dozen and are also most likely well-trained on the operating systems they work in. But have you spent the same amount of time working on camera systems? Choosing a company that knows its products can save you massive amounts of headache in the long run. Checking their website may give you some insight as to whether or not they know what they are selling. However, too often material on websites gets stolen, reworked and reworded, and then re-posted again. You really need to contact the company. Use several methods. Call them. Email them. Fax them. Use the methods you prefer. Do a little discovery to see what other contact and information forms they may have. A running forum perhaps? An active and updated online database? A video database? A YouTube Channel? All of these things can and will help you acquire knowledge quickly and efficiently when you need it.

Clearly the quality, capability, and performance of the equipment you choose is important. But also is being able to learn how to use it, getting it repaired or replaced, and upgraded. In today’s market, there are so many good (and bad) alternatives that you really need to consider the place you purchase from as much (if not more) than the equipment itself. After all, you may save 50% on your purchase. But what good does it do you if you can’t use it at all?

How to Capture License Plates with Security Cameras

Capturing License Plates With CCTV Surveillance Cameras

Using a surveillance camera to capture video footage of the license plates of vehicles that are entering and leaving an area has proven to be an effective way to have a record of the traffic at the location. Law enforcement agencies across this country are making use of this technique more and more commonly. It has already helped them to gather information that has helped them follow vehicles thought to be driven by individuals that were suspected of crimes, even when the officer is nowhere near the vehicle. The data that these cameras provide can be invaluable if a crime takes place, allowing someone to review footage and know who was in the area with certainty. The data collected about these license plates can be more helpful to law enforcement officials when trying to identify a suspect then the highest quality images of a suspect’s face. The installation of security cameras for this function may seem deceptively simple but if it isn’t done correctly you will not get the video that you need. This article will provide with the information that will you to accurately record video footage of license plates every time.

The first consideration that you should look at for licenses plate capture is the location. Finding the right place to record useful video of these small fast moving targets is a key element in the process. The place where you set up for this should be a place where traffic is already controlled in such a way to be beneficial for this process. Someplace where traffic is already forced to stop, such as a stop sign or the gate of a community, is an ideal spot. The entry way of a gated community is probably the best location because it will also be a place where there are fewer lanes of traffic and you will need a dedicated license plate capture camera for every lane of traffic that you’re monitoring, so fewer lanes will require fewer cameras to get the video footage that you want.

The next thing that you should consider for this process is making sure that you have the proper equipment to record the best possible video of the license plates. There are many different security cameras on the market today that offer high quality video, but few are actually designed to record high quality video of a license plate. The cameras that perform this function correctly have to be able to deal with the glare of light bouncing off the reflective surface of the plate, angles that are often challenging, widely varying illumination levels, being able to record video of a moving target that isn’t blurry and they usually have to cope with moderate to long distances. All of these factors, in addition to other location specific issues that haven’t been mentioned, that the camera must deal with are the reasons that you really need to have a surveillance camera that is specifically designed to capture video of license plate despite the difficulties.

Another part of this process that you must account for, in order to do it correctly, is properly monitoring the area where you will be identifying the license plates as well as providing an exterior view of the vehicle. A camera that can capture video of the car or truck and its activity will provide you with some very useful information particularly when you can identify the vehicle’s license plate at the same time. Making sure that you at least have a reasonable high resolution camera for this overview purpose is a very good idea, but it doesn’t need to provide the same type of high quality of video that the license plate camera should. A moderately high quality camera for the overview role will allow you to have a high level of detail in the video shot to help you get an accurate understanding of what type of vehicle the license plate is attached to and how many passengers are in it. This over view camera can also provide other details about the vehicle such as the relative speed that it’s traveling and whether it’s being driven recklessly or not. It’s also a good idea to get a camera for this purpose that has a varifocal lens so that you can adjust it to the camera view that’s needed from the position that’s available for mounting the camera. This type of lens will let you compensate for a reasonable amount of distance from the targeted area and make sure that it’s focused on the exact point that you want.

So now we have established that an overview camera needs to be mounted in such a way that it can view the traffic choke point where you are going to be capturing video of license plates. The next step is to make sure that you have the surveillance camera that will actually be doing the license plate capturing in the right place. The traffic point that you choose for this installation should allow you to know where the target vehicle will stop. The license plate capture will need to be positioned in such a way that it’s field of vision will be focused and the lens will need to be zoomed in to the point that the license plate will take up about sixty percent of the camera’s view. Make sure that you take into account the varying heights of the different types of vehicles that will be traveling through the area. You will need to have one dedicated license plate capturing camera set up this way for each lane of traffic that you wish to monitor.

Once you have these cameras set up in the manner that’s described in this article, you should be ready for monitoring the traffic in the area in great detail. It’s a good idea to test how the camera views will catch the license plates where the vehicles will be stopped and the make the fine tuning adjustments in order to guarantee that you will be getting the video that you desire.
