Security cameras are made and used on a daily bases for a number of reasons. They can be used anywhere from gas stations to military personnel vehicles. Specifically, security cameras are used to view or record any person, place, or thing without being there in person. There are many different types and styles of cameras and they are all used in different settings. Learning about the different types of security cameras available can give you the upper hand when needed for a specific task or location. Deciding which is the best security camera for you will depend on your situation.

Types of Security Cameras

There are many types of security cameras in the security world today. They all fall into a few main categories including Analog, Network IP, and HD-CVI. Even though it might not sound like much, each side offers many different options and capabilities which can affect camera quality and your wallet. There are advantages and disadvantages to each type and overall get the job done.

Styles of Cameras

Cameras come in many different shapes and sizes and, depending on where you place them, can give you better understanding of what you will need.

Box Cameras

Box Security Camera

Box cameras are very customizable and offer many different lenses sizes. You can either have them mounted as is, or you can put them in a case called a box, hence the name. Box cameras are also capable of being mounted in extreme weather because some of their boxes have heaters and blowers built in. Most box cameras are dual voltage and have the capability to support alarms and strobes connected. Downsides are they are bulky and require more experience for setup and installation.

Bullet Cameras

800 TVL Bullet Security Camera

Bullets are also a great choice because they have a greater viewing angle then most other cameras. Bullets can also have larger range of different lenses built in so you can zoom in close on a shot or have a wider viewing angle. The downside is they are not vandal proof and very noticeable.

Dome Cameras

700 TVL Vandal Dome Security Camera

The most common camera used is the dome. Domes can be used in many different locations and can take a punch or two. Domes have wide viewing angles for greater versatility. They are also more discreet, when it comes to hiding your cameras, then when it comes to a bullet. They also can take a couple of hits because of their robust structure.

PTZ Cameras

700 TVL PTZ Security Camera

PTZ’s can give you more coverage than a conventional pre-positioned camera. P-T-Z (Pan-Tilt-Zoom) cameras are made for you to control the camera so you can see what’s happening even if it moves out of your typical viewing area. Some PTZ’s can also track objects or people so you don’t have to move it yourself. Downside is that they can be pricy and bulky.

Hidden Cameras

Hidden Mirror Camera

Hidden cameras are made for you to know where they are but no other person will. They can be just about anything: clocks, smoke alarms, phones, mirrors, and many others. Disadvantages are they typically can’t see or record very well at night.

License Plate Cameras

License Plate Camera

License plate cameras are built to capture a license plate at high speeds. These cameras are used for highways, entry gates, business, parking garages, and more. They offer advanced technologies that allow you to focus on the license plate in light or dark conditions.

Thermal Cameras

Thermal Imaging Camera

Thermal cameras are designed to allow you to see heat signatures in any light setting. This can help you distinguish differences between important and non-important things during motion detection. For example, branches blowing in the wind and a person walking. This may not give you the best image but it can trigger a separate camera to record the situation.

What is IR?

There are also other features that security cameras can have. Cameras can be indoor or outdoor depending on the camera. Some Cameras come with IR (Infrared Technology) that allows them to see at night. IR is a light that is invisible to us but is like a flood light for a camera. IR is usually built onto the cameras themselves, but can also be placed separately for cameras that have the capability to view the light. The style of camera can give you your best view and placement for anywhere they need to be.

What is IR

Analog Cameras

Analog cameras have been used for many years and have done its job very well. The way that it works is by the type of signal it sends to its receiving end. It sends an analog picture of what it views and it can either record by tape or by digitally converting it to record on a hard drive. The old way would be the tape, but now we have either a computer with a card that receives the signal and converts it to be stored on a hard drive or a standalone unit called a DVR that does the same thing, just without using your personal computer. DVRs are recommended because they can be hidden and require half the power (electrical and processor). Over the years, analog cameras have improved profusely by increasing frame rates and quality of resolution. The latest technology for analog cameras is called HD-CVI. This is an analog technology that allows you to record 720p-1080p resolution.

Network IP Cameras

Network IP Cameras are starting to become more affordable and practical for business and homes. Network IP cameras are cameras that function all on their own and don’t require any standalone unit to view and in some cases record. The way they work is through your new or existing network and is given a IP address (Internet Protocol) which allows it to be accessed through your network for viewing or recording purposes. Network IP cameras can be controlled also through a web based program for initial set-up and to adjust and control the camera like a PTZ. IP cameras are also usually in High Definition. They can record as high as 10MP (Megapixels) in resolution but average cameras record at 1080p. Megapixel is one million pixels in a specific image, so 2MP is similar to 1080p. The downside to using Network IP cameras is they run through your network to be viewed and/or recorded. This is a problem if you have a lot of cameras or if your cameras are recording in 1080p or above. Networks can only handle a set amount of send and receive data before bogging down. This drag increases when you are recording and viewing simultaneously inside your network and out. There are ways to overcome this problem by either getting a managed switch or making separate networks for specific amounts of cameras.

Auto-Tracking Dome Camera

Written By:
Wednesday, April 27th, 2011

Have you tried an auto-tracking dome camera?  Be careful if you do because once you get hooked on them, it is pretty difficult to keep you from getting more.  These cameras represent some of the highest quality electronics available today.

What is an “Auto-tracking Dome Camera?”  It’s a special type of PTZ (Pan-Tilt-Zoom) camera that can lock onto moving objects and follow them where ever they go (within line of sight to the camera).

To use such a camera you first need to install it, and then set it up, and finally let it work so you don’t have too!  Auto-tracking Dome Cameras have circuitry built right in that allows them to recognize a moving object, get a lock on the target , and follow it until it leaves the area of the Field of View for the camera.

This is particularly useful if you require constant live monitoring of your security system.  For example, if you were using this camera in a parking lot, not only could you set it to watch cars come and go, but it could even track the people getting out of the cars.

Security Camera King offers two different auto tracking dome cameras, both made by Veilux.  Product# VP-ATDNC27X has an optical zoom of 27X and an additional digital zoom of 10X.  This means the total zoom effect attainable with these cameras would be up to 270X.  In addition here are some of the features of this camera:

  • 520 TVL high resolution output;
  • Minimum illumination is 1.0 Lux for day mode and .5 for night mode;
  • Automatic stabilization of images by reduced flicker;
  • Motion tracking, Intelligent Surveillance with an alarm function;
  • Preset, auto cruise and specified pattern scan function;
  • 360 degree continuous pan;
  • 0 to 9 degree tilt from horizontal plane as well as auto flip 180 degrees;
  • Iris, focus, and white balance;
  • Backlight compensation;
  • Wide Dynamic Range (WDR); and,
  • Outdoor version is IP66 rated for use out doors;

The second camera is very similar to the latter, with some slight advantageous changes.  Product# SVP-ATDN36X has an optical zoom of 36X and an additional digital zoom of 10X.  This means the total zoom effect attainable for this model would be 360X.  This camera is vary similar to the previously mentioned model so the features list will only include those features or items that are different:

  • 540 TVL high resolution output;
  • Minimum illumination is 0.1 Lux for day mode and 0.01 Lux for night; and,
  • Heater and blower included in outdoor model.

It’s only fair to note that PTZ cameras that can be controlled remotely, when coupled with special software on the DVR, can also track or follow objects.  However, in this case instead of the technology lying with the camera, it is actually the DVR that contains the software and does the work.  It uses software to analyze the video sent to it, and then initiates the commands to the camera to PTZ so as to stay with the object tracking it.

So as you can see today’s digital video camera systems can handle some pretty complex tasks without the need for any human interruption.  What’s more is that on PTZ camera mounted in the proper place may often be able to take the place of 3 or even 4 stationary cameras.  Even though the PTZ camera may be in the moderate price range this fact alone helps to reduce costs, if not directly than at least indirectly.

Another added value feature of Security Camera King’s DVRs is that all but the Elite Mini Economy can control PTZ cameras with just a mouse.  Point to where you want to go, and the PTZ camera aims there.  However, if you prefer more conventional means of control, Security Camera King does sell a separate PTZ control that has a joystick and a keyboard designed specifically for use with PTZ cameras.
