Mini Camera Guru: High Def Doesn’t Mean High Returns
Contemporary Security Camera systems now use digital technologies and what makes these devices digital are the image sensors behind the camera lenses the element in your mini camera that radically change the light and image captured by your camera’s lens and converts them into digital signals. These signals are either stored in your camera’s internal memory or sent without delay as a digitized video file to a P. C. Or Digital Recorder.
The costs of digital mini cameras have gone down mainly due to the means these image sensors are far easier to produce now than they did a few years back. These sensors convert light into electrons and there are 2 major chip technologies used to turn out these sensors : CCD or Charge-Coupled Device and CMOS or Complimentary Metal-Oxide Semiconductor image sensors. CMOS chips are easier to produce and are thus cheaper than their CCD counterparts.
These technologies have developed quite significantly at present times that electronic cameras can now capture and produce high definition video images of the highest qualities and image resolutions. As a reseller or online retailer of mini camera devices, you could have a demonstrable appreciation of these technologies to maintain a balance between getting hi-def products and supplying what your customers actually desire. Hi-def cameras which sell at higher prices may not necessarily mean higher returns for your investments as many stores would ultimately find out .
Understanding Digital Mini Camera Technologies
The following described in a nutshell the most common and most well-liked Digital Camera technologies in existence at the moment that all online Security System outlets should know.
* CCD Sensor Chips
Most electronic cameras today use CCD sensor technologies. CCDs were a consequence of the search for low-cost and easier-to-produce camera solutions that would eventually replace both the need for mechanized screens and the utilization of film for cameras. In layman’s terms CCDs are the electronic versions of the eye.
There are 4 kinds of CCD sensors : Linear, Interline, Full-Frame and Frame-Transfer CCD cameras. Linear CCDs use only a single row of pixels and employs motors to physically move the pixel sensors. They are now not commonplace except in flatbed scanners. Interline CCDs are far more commonly utilised thanks to the higher cost and shutter restrictions of full frame transfer CCDs.
* CMOS Sensor Chips
CMOS appeared as an easier-to-manufacture alternative to CCDs as it employs the same manufacturing processes used to turn out semiconductor chips worldwide , thus making them less expensive than CCDs. On top of that, CMOS sensors use less power than CCDs but include other processor functions such as analog-to-digital conversions, white balance adjustments, load signal processing and other camera controls.
* Interline CCD Sensor Chips
Interline CCD chips have a compound configuration that incorporates an interlaced photosensitive and masked storage array, giving them better electronic shuttering functions which are the main lack of the frame-transfer CCDs. It also has an electron drain that prohibits electron overflow which is the main cause of overexposure for diagonally opposite pixels, causing the blooming or smearing effect on images and video feeds.
* Super HAD CCD Sensor Chips
Almost all Sony CCD cameras in the market now use their trademark Super HAD ( Hole-Accumulation Diode ) CCD sensor chip that provides better sensitiveness and smear rejection proportion than standard CCD types. It utilizes a new semiconductor technology developed by Sony Multinational whereby 2 micro lenses are placed on top of each photodiode which can enable the sensor to collect more photons from incoming light.
Sensor Chip Technologies and Image Resolution
Selecting which mini camera sensor chip technologies would give out the best resolution would depend on the exact application and environment these cameras will be used. Although structurally speaking, CCD cameras have better light sensitiveness and higher resolution making them wonderful for use with fine quality photographs. For low-light applications Interline CCDs would work fine especially if used together with IR light enhancements, even though it can still function well on other light levels.
CMOS cameras on the other hand have lower sensitiveness and lower resolution making them excellent for lower costing starter level cameras, despite the fact that more modern versions out in the market are promoted to have qualities that can approximate that of CCDs. Nonetheless CMOS cameras work best when the surrounding light is unfailing such as in office corridors. The chip is susceptible to IR light and won’t work best in bright sunlight. It is also less sensitive for little light making them bad for use outside at night.
The Sony Super HAD would provide the best quality in terms of better sensitiveness and smear rejection and is advantageous to be used in any locations and conditions, whether or not it is night or day, clear or foggy, and dark or light. Nonetheless these cameras would bring a bigger price bracket than standard CCDs.
High Resolution or Lower Price?
CCDs would get higher prices than their CMOS equivalents making them superior for higher end use, while CMOS are adequate for starter-level and mid-level usage. CMOS chips however consume less energy than CCDs therefore CMOS cameras will last longer with batteries a major element for cellphone as well as Wireless Mini camera security applications.
Sony Super HAD CCD cameras will cost higher compared against standard interline CCDs. For example, a mini camera that uses a Sony interline CCD chip will cost approximately $93, while a similar camera that utilises a Sony Super HAD CCD chip instead will get a price over $117. There are developments however in CMOS sensor technologies, which makes them approximately the same caliber of quality that CCDs have but at lower price levels.
But what would some people prefer for their security systems? A highres camera that would fetch lots of bucks, or a mini camera with inferior resolutions but will be available at very reasonable prices? Again, the answer would depend on what the client wishes or the environment where the cameras would be applied. Some will prefer high spec and light sensitive cameras when used in intense locations such as outside at night. On the other hand, other applications that don’t actually necessitate Hi-D video output would do well with lower priced cameras.
As a retailer of security devices, it is very important that you understand what your customer wishes and match your products to cater to these needs . It wouldn’t be moneymaking to stock on higher-priced high-definition mini cameras ( which should offer you higher margins ) — if your customers prefer lower price alternatives.
