What is the Best Security Camera Type?

Written By:
Thursday, October 9th, 2014

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.

Motion Detector Hidden Camera

Written By:
Tuesday, April 19th, 2011

A motion detector hidden camera can be just what the situation calls for when covert monitoring is required.  These hidden cameras can be used just about anywhere and provide a remarkably good digital video image.  There are a few different types of motion detector hidden cameras and in the following article will take a look at each.  Before we look at individual motion detector hidden cameras, let’s quickly review how a digital video security camera system works.

Modern digital video security camera systems are component systems.   That means that each major device used in the system doesn’t have to be the same brand, type, or made by the same manufacturer.  This alone has great implications for a motion detector hidden camera because it means you can always add this camera to your existing system without any major difficulty.

A typical digital video security and surveillance system consists of three major components (devices); one or more cameras, a Digital Video Recorder or DVR, and a monitor (which is needed for setup after which its use is optional).  Since this article focuses on motion detector hidden cameras, we’ll take a closer look at how the digital video camera works.

The primary function of a digital video camera is to transfer an image created by reflecting light into an electronic signal that can be recreated and displayed on a monitor and/or saved as a digital video file.  The same holds true for the motion detector hidden camera.

The camera accomplishes this by using lenses, sensors, and Integrated Circuit (IC) electronic chips.  Each camera has a “field of vision”; this is the area that the camera can “see” through its lens.  The image the camera sees through the lens is made up of reflected light.  The lens gathers the light image and focuses it onto a very small sensor chip ranging from 1/4 inch to 1/2 inch square.

There are two such sensor chips available for use; however both yield the same results, transferring light energy into electrical energy.  The Charged Coupled Device or CCD and the Complementary Metal Oxide Semiconductor or CMOS.  Both sensors produce a video image in the end, but in the process of getting there, their approach is different.

The CCD and CMOS are fairly comparable these days, but they both still have different slight advantages.  Typically, the CCD creates a higher resolution and higher quality image, but it does so at the cost of needing electrical power.  The CMOS doesn’t create as detailed an image as the CCD, but it is advantageous to use in standalone motion detector hidden cameras because it uses much less electrical power.

So, for applications that include the use of a motion detector hidden camera, the camera sensor will vary depending on whether the camera operates off of a full-time power supply or batteries.  Normally, one is apt to see more CMOS sensors used in standalone battery operated cameras and the CCD used when the camera is part of a digital video security system that has a full time power feed.  This is not a hard and fast rule though, because as technology continues to advance CCDs are created that use less power and CMOSs are created that deliver a higher quality digital video image.

How covert can a hidden camera be when it is hidden inside a motion detector, something that is used for an alarm system?  The answer is very covert.  If you have an existing alarm system chances are you have existing motion detectors mounted for that system or perhaps you have existing motion detectors to control the rooms lighting.  At any rate, these devices are very common in business and home applications.  No one would suspect that the motion detector would also be a digital video camera.  (Incidentally, most motion detector hidden cameras DO NOT have a functioning motion detector.  The available room inside the detector is usually consumed by the camera.)

Security Camera King has three different types of motion detector hidden cameras available for purchase; a wired 420 TVL motion detector hidden camera (Product# CV-LXPIR), a wireless black and white (Product# HC-MOTIOD-G) or color (HC-MOTIOD-GC), and a 380 TVL (Product# HC-MOTION-DVR) standalone camera with its own built-in DVR.

High Quality Hidden Camera

Written By:
Friday, February 18th, 2011

There are situations when designing your digital video security and surveillance system that you should consider using a high quality hidden camera. These cameras come in a variety of types, shapes, and sizes and connect to your system just like any other digital video security camera.

Today’s technology has allowed the digital video camera to be incredibly small and still produce a full-size high quality video image. Because of this, a high quality hidden camera can be disguised or concealed in just about any object. This is important when effective covert security and surveillance monitoring is required because the key to success is not being detected.

It seems as though there are almost as many high quality hidden camera models available as there are non-hidden models. As usage becomes more popular and demand increases, so does the variety of objects arrive on the market with these cameras embedded in them.

Most high quality hidden cameras use a 3.7 mm diameter lens and a 1/4″ or 1/3″ sensor. The sensor is what the lens focuses the light image on. It is also what is used to convert the light image into a potential electronic digital video image. There are two different sensors and every camera uses one; the Charged Coupled Device or CCD and the Complementary Metal Oxide Semiconductor or CMOS.

The rest of the internal working parts of a high quality hidden camera are just electronics. “Just electronics” doesn’t mean to lessen the sophistication and power of the technology, rather electronic technology as exponentially increased in the past several years. “Just electronics” means to imply that although there is a lot of circuitry, it can be accomplished by using very small Integrate Chip (IC) chips in a small amount of space.

Security Camera King offers a vast supply of high quality hidden cameras, hidden camera systems, and wireless high quality hidden cameras. The following is just a partial list of the items we offer:

Hidden Camera With SD Card

Written By:
Wednesday, February 9th, 2011

There are times when covert camera monitoring and recording are necessary and one of the best devices for this purpose is a hidden camera with SD card. Thanks to recent technological advances in the computer world as well as in general electronics, a camera can be made as small as to fit in the shell of an average writing pen.

When it comes to the appearance of a hidden camera with SD card, there are many types from which to choose. These cameras come in “bare-bones” mini versions, where the camera is basically undisguised but is small enough to be hidden, to disguised versions that look (and often times function) as clocks, mirrors, safes, stuffed animals, and many more.

But what exactly is a hidden camera with SD card and how is it able to work? We’ll answer those questions and more in the following article.

The secret behind the success of the hidden camera with SD card is its incredibly small size. Another technological feature is its relatively low demand for power consumption. Yet another is the ability to save digital video images to an SD card, a relatively small device that can pack a big punch in memory capacity these days. Let’s start from the beginning.

A digital video security camera system works by capturing color digital video images with the camera, transmitting those images to the Digital Video Recorder or DVR unit, and saving them on the DVR’s hard disk drive and or displaying them on a monitor. Technically, a monitor is only needed for the system to set it up; that is, fine tune and adjust initial settings. However, if the user wants to monitor the digital video live (or later) the monitor will be needed. The important point here is that a digital video system can consist of just a digital video camera and DVR.

Basically that’s exactly what a hidden camera with SD card is; a digital video camera with a DVR. The key component of the digital video camera is the sensor that is used to create the digital video image. One of two different types of sensors, a Charged Coupled Device or CCD or a Complementary Metal Oxide Semiconductor is used. Generally speaking, a CCD provides the highest quality image at the price of power consumption while a CMOS provided a good quality image at a much lower demand for electrical power.

As technology continues to increase, the power demands for the CCD become much less and the quality for the CMOS becomes even better. Since many hidden cameras with SD card are standalone units placed inside other objects to disguise their appearance, power consumption may be an issue. For that reason many hidden camera with SD cards use CMOS sensor chips.

Although the CCD and the CMOS work a little differently, they both produce the same outcome, a relatively high-quality digital video image. They do this by transferring light images into electrical impulses. These impulses can be measured and compiled into data that creates a digital video image.

One of the most impressive features of digital video cameras is that they can produce these high quality digital video images with a CCD or CMOS the size of a square that is only 1/4 inch! In addition, a wide angle lens is usually used to focus the image on the sensor and these lenses are often as small as 3.7 mm in diameter. Obviously, the small sensor chip and lens combination “paves the way” for camera to be used in other devices as a hidden or disguised camera.

After the camera has created the data for a digital video image micro-circuit technology take over from there. First, an on-board analog-to-digital converter chip transfers the analog data into digital data. Then another circuit compiles and condenses the data to create a digital video file. The digital video file is saved by the DVR, however this cameras DVR records to an SD (Secure Digital) card instead of a hard disk drive.

SD cards are non-volatile memory containers that are used in many electronic devices such as cameras, cell phones and MP3 players. All the user has to do is remove the SD card, plug it into their computer, and download the digital video file created by the hidden camera with SD card.

On-board power for hidden cameras with SD cards may be supplied by a battery, or the camera may actually tap into the power of the device in which they are hidden.

Hidden Camera In TV

Written By:
Tuesday, February 8th, 2011

Ever need to watch those who are watching? That’s exactly what a hidden camera in TV can do. In fact the possibilities for different types of hidden cameras are nearly endless these days, thanks to 21st century electronic technology.

The current technology that abounds is so compact and efficient, that a hidden camera in TV is rather simple, especially considering the fact that we currently have hidden color cameras that are made to look like the head of a typical Phillips screw. (See Security Camera Kings product #HC-SCREW-WC or go to this page.)

Putting a hidden camera in TV is easy because there is usually lots of spare room inside the television set case to allow for the camera and accompanying electronics. Who would suspect that the television is actually watching them?

Perhaps the real question here is not how they put a hidden camera in TV, a screw, a stuffed animal, a clock, or just about any other object but what is it about the technology that makes such a thing possible? In the following article we’ll describe how a miniature hidden camera works and mention some the technological improvements that have occurred over the past few years to make this possible.

There are two types of digital video security and monitoring, overt and covert. Overt monitoring occurs when no attempts to conceal, disguise, or hide the activity to monitor or record images are made. Covert monitoring is just the opposite; the camera and other equipment is hidden, concealed, or disguised so as not to readily reveal its presence. In the world of security and surveillance, both overt and covert monitoring is needed. Thus, the demand has created the need for a device like a hidden camera in TV.

Covert monitoring devices may include just the camera or it may include an entire miniature digital video security camera system. A typical full-size digital video security system not only has cameras, but a Digital Video Recorder or DVR and an optional monitor as well. Hidden miniature digital video security camera systems also include the camera, but in addition, contain a miniature DVR as well. But before we get ahead of ourselves, let’s talk about the technology that allows this to happen.

First a full-size standalone digital video system uses digital video cameras that send their digital video signals to the DVR unit. The DVR unit also contains a highly specialized computer processor called a Digital Signal Processor or DSP. The processor is like the processor in a personal computer but is designed to operate specifically to deal with digital video data. The DSP gathers the digital video data sent to it by the digital video camera and creates a digital video file that can be viewed live on a monitor and/or stored in a digital file format on a hard disk drive on the DVR.

Miniature systems, like a hidden camera in TV system, also have a camera and a DVR. However, the DVR circuitry is contained on a small Integrated Circuit (IC) chip and is either stored in on-board (another type of IC chip) memory or on an SD card or similar device. As technology improves, memory chips become smaller and smaller while their capacity for storage becomes greater. This is just one of the features that provides for making miniature digital video security systems possible.

As for the cameras, there are several technologies applied here to make the devices incredibly small while still yielding fluid, relatively high-quality video. First, many hidden, miniature digital cameras use a highly refined wide angle lens. This lens provides the camera with a significantly wide field of view even though the lens itself is often only 3.7 mm in diameter.

Next the electronic sensor chips used to convert the focused light reflected from the image through the lens can be incredibly small. Typical sizes for these sensors called Charged Coupled Devices or CCDs or Complementary Metal Oxide Semiconductors or CMOSs is 1/4, 1/3, and 1/2 inch square – and that is for full sized cameras.

Finally, as already mentioned IC chip technology continues to get smaller and more sophisticated over time. This allows for an analog-to-digital converter circuit and transmitting circuits to exist in miniature IC chips. So when all of these technological improvements are packaged neatly and tightly together, many covert recording devices are possible, including a hidden camera in TV.
