Video & Camera Equipment

Where can I find a good camera security system?

I have been looking… I know i can get a system at SAM’S for 500 dollars but it only has 4 cameras… i haven’t found one that is reasonable that may have 8+ cameras without paying thousands… I am visually impaired and we’ve been having some “snoopers” lately and want to beef up the security around the house (visual security with taping capabilities)… if you know of something good AND inexpensive, please tell me…

Good an inexpesive is a relative term. If you think 500 bucks for a DVR with 4 camera’s is too expensive then forget about 8. – Personally, I would never buy the system you are looking at. My customers tend to expect quality and reliability as do I.

Typically speaking, retail camera’s, like the type you are looking at, are fairly substandard when compared in quality to those on a professional level.

Your best bet is to go at it with some knowledge of the technology, I wrote an article on the subject awhile back but most of the info still applies. I have pasted some of it here. You can find more information on security related topics on my website at http://www.keepsafesystems.ca

—————————————————————————-

The starting point of any C.C.T.V. system is the camera. Simply stated, a camera is a light sensitive device that converts particles of light into electrical impulses, however, there is a vast difference in the quality of cameras available to the consumer. Factors that differentiate the various cameras include whether they are color, black and white, light sensitivity, image resolution and image transfer technology. The consumer must also consider the inherent advantages and disadvantages in each of these different camera technologies and decide which features best fit their individual needs and goals.

In the past, color cameras have been both very expensive and lack-luster in their image performance, when compared to black and white cameras. New technology is now bringing the innovative technologies closer together in both the price and performance scale. The current differences between the two technologies are almost entirely limited to light sensitivity and light reactivity.

Light sensitivity is measured in LUX. The lower the LUX rating, the higher the sensitivity to light. It is important to keep in mind that even the best-rated cameras are limited by the technology of the day, as well as the visibility conditions present at the time of the surveillance. Although great advancements in low light surveillance continue to be ongoing, the image quality in a low light situation will rarely be up to the standards of daylight surveillance.

Color cameras, although much more appealing on the outside when compared to their black and white counterparts, generally offer less low light sensitivity than a black and white camera. The other advantage of black and white cameras over color cameras is its ability to “see” infrared light, which is invisible to the human eye. You can test this by aiming a standard television remote at a black and white camera while watching the monitor, the flashes you see are bursts of infrared light. The advantage of this becomes apparent in the ability to light up a dark area with infrared light, thus making images visible in almost pure darkness. With the color camera the area will appear unlit, however, to a black and white camera, the area will appear almost like daylight.

The black and white camera‚s reactivity to the invisible light spectrum can also pose a disadvantage in certain applications. Infrared light, although not visible to the human eye, is found in abundance in many everyday situations. For example, when aiming a black and white camera at hot pavement, it will “confuse” the camera resulting in an unbalanced image. Professional grade black and white cameras often incorporate infrared cut-filters. These cut-filters inhibit the infrared light spectrum in turn decreasing the cameras low light sensitivity.

The C.C.T.V. Industry measures image resolution in horizontal lines. The higher the line rating, the clearer the image will appear. With this fact in mind, consider that all electronic components within a C.C.T.V. System, from the camera, to the VCR, to the monitor. These items are all rated in the same way. The actual resolution of the entire system will only be as high as the lowest rated item. For example, if you have a camera rated at 450 lines and a monitor rated at 300 lines, then the result will be 300 visible lines of resolution because the monitor is the lowest rated item in this example. Another point to keep in mind is that the line rating is “Total lines” not lines per inch. Therefore a 12″ monitor with a 300 line rating has a far better clarity than a 17″ monitor with the same line rating.

The most recent and predominant advances in the C.C.T.V. Industry are the changes in image transfer technology. This technology deals with how the camera takes light particles and converts them into electronic images. Without going into too much detail, image transfer technologies include the following:

Phosphorus Tube Cameras – This camera has low quality, old technology and is susceptible to “image burn”. Image burn is when intense light sources will burn themselves into the camera‚s light receptor resulting in the image appearing “memorized”. Although this is not a problem with modern day cameras, image burn can still occur on monitors. Tube cameras are also known for poor low light sensitivity.

C.C.D – Also known as “Chip cameras”. This camera is the most standard of cameras in the professional realm. C.C.D. cameras do not suffer from the problem of image burn and can incorporate various methods of signal processing, which offers a high level of flexibility to the installer.

CMOS Transfer Cameras – These cameras are very small and continue to get smaller as the technology advances. Although very attractive in their size, CMOS cameras generally do not offer the signal processing, image quality or low light sensitivity of the higher priced C.C.D. camera models. However, the technologies are slowly growing closer together to the point where CMOS cameras may eventually take over the Surveillance Industry.

The Surveillance Industry has continued to move towards the implementation of color cameras that switch to black and white, or even infrared in low light conditions. Although there are some models currently available on the market, the technology is not at a point where it is affordable enough to be manufactured on a large scale.

Network Security for Embedded Systems $151.35 It is widely recognised that security is a concern in the design of a wide range of embedded systems. However, security for embedded systems remains an unsolved problem, which could create greater challenges in the future than security for mainstream computers today. The promise of universal connectivity for embedded systems creates increased possibilities for malicious users to gain unauthorised access to sensitive information. All modern security protocols use privatekey and publickey algorithms. This book investigates three important cryptography algorithms (RC4, AES, and RSA) and their relevance to networked embedded systems. Limitations in processing power, battery life, communication bandwidth, memory and costs constrain the applicability of existing cryptography standards for small embedded devices. The aim of this book is to find feasible security solutions for networked embedded system applications. The above mentioned cryptography algorithms have been ported to three hardware platforms (Rabbit RCM 3000, Xilinx Virtex 4 FPGA with MicroBlaze softcore, and a Linux desktop machine) in order to simulate several real world scenarios.

A Method for Analyzing Security of SoaBased Systems $116.3 Currently, the securing of SOAbased applications is still a challenge. Although some related techniques have been proposed and presented in academia and industry, it is still difficult to check SOA quality in security aspect from an architecture view. In this thesis project, a method for security analysis in SOA is introduced and investigated. The method intends to be used for analyzing security of SOAbased systems on architecture level. To demonstrate the method, a prototype supporting the method is introduced and implemented. And the method and prototype are also evaluated respectively based on Technology Acceptance Model. The evaluation result shows that the prototype supporting the method is a promising inspection tool to detect software vulnerability.
