Security camera system checklist

Black/White or Color? Color Cameras are more popular, due to their clearer identifications. But, in low light conditions, B/W cameras are more ideal, because they generally require less illumination. Newer models of Day/Night cameras work as color camera during daytime and B/W at night. 2.What basic equipments are necessary to start video surveillance? Camera body, Lens, Mount, Cable, and Power Supply. Some cameras (like dome and bullet type cameras) come with built-in lenses. You will also need CCTV monitor (or regular TV), quad splitter or switcher to combine more than one camera, recorder (like DVR), outdoor housing case and other accessories. Wireless systems are great way to avoid cabling. Network based Web Cameras and DVRs are for remote surveillance. 3.What if I need more than one camera? A quad splitter, 4 channel or 8 channel switcher, or multiplexer can be used to combine multiple cameras into one monitor or recorder. DVRs usually come with a built-in multiplexer. 4.Hidden Cameras If you want a hidden camera, you have two options; you can either build one with a mini or an ultra-mini camera, or buy one. Some ultra-mini cameras are only as big as a quarter to hide more easily. Hidden cameras built-in clocks, radios, or smoke detectors are also available but are generally more costly. Please note that, in most US states, using hidden cameras with audio in a covert way is prohibited. 5.Placing cameras outdoors You may use an outdoor housing case, with or without heater and/or blower. The heater and/or blower built-in housing cases generally require a separate power source. Some cameras are made water resistant and do not need separate housing cases. Some of these also come with removable sunshields. 6.When are infrared cameras necessary? Economically commercialized infrared cameras, some also water-resistant to be installed outdoor, can see up to 40 to 80ft distance in total darkness. You may also use infrared illuminators, which can illuminate up to 100ft (Color cameras, unless their IR filter is removed, do not work with infrared illuminators.) Infrared cameras work as ordinary video camera during daytime. Color infrared cameras work as B/W ones at night. 7.What is an ideal angle for a lens to cover? Widely used and recommended angle of view of the lens for surveillance purpose is 72o to 78o. Narrower will give you clearer pictures. Wide angles like 92o can cover more area but it may show distorted pictures. 8.Vari-focal vs. Zoom Lens Focal length and focusing for vari-focal lens should be adjusted respectively while zoom lens focuses automatically when the focal length is adjusted. Manual zoom lens needs to be manually adjusted while motorized zoom lens can be controlled with a remote controller. 9.Manual Iris vs. Auto Iris

If the lighting condition changes significantly and frequently, like the sun, an auto iris lens is required. If the lighting remains same, a manual iris or a fixed iris lens is recommended. Most CCTV cameras accept DC auto iris lens while some special cameras use video auto iris lens.

Were photographers for a reason. We like or are interested in what we see in the world around us. Wed like to capture an image for ourselves or to show other people.

However, we have a problem. Well never be able to store the representation of the image in our minds with all the complexity of the processing of our eyes and brain.

Our eyes look at only a small area of the image and our brain fills in the rest of the surrounding detail. Our eyes have an iris, which adjusts to give us the exact exposure to the intensity of the light so that we can see the maximum detail in any part of the scene. The result of all of this is that we see everything around us as perfectly exposed (except when its too dark to see).

When taking photographs, all areas of the image have the same exposure. We can adjust the exposure but areas, which are darker or lighter than others will be just that, light, or dark in the image.

The aim of the photographer has always been to keep details in the darker and lighter areas. We use tricks like fill in flash, graduated filters, polarising filter etc. to keep important details but often we just accept that our photographs will just have a blow out sky or dark shadows. After a while, we start using shadows and high lights creatively as part of our photographs, creating an image that you would not be able to see directly using your eyes.

We could start taking photos during the night using screen lights and we can go out at dusk to try to balance the intensity of the light left in the sky to the artificial lights in our towns and cities.

As photographers we now have a wide range of additional tools in our tool box that allow us to adjust, enhance and even change the natural picture that we see through the lens. It enables our eyes to see what our brain creatively imagines.

The Tamron 18-250 Review – Is This A Good Update

I’ve just tested the Tamron 18-250mm f/3.5-6.3 lens on my Canon EOS 7D camera and now I am writing this Tamron 18-250 review to give you the result.
This lens is also available for Nikon (with built in motor), Pentax, and Sony cameras. Tamron also made an upgraded version of this lens, called the 18-270mm VC for Canon and Nikon DSLR.

This lens is an upgraded version of the Tamron 18-200mm lens. If you have read my Tamron 18-200 review previously, you know that I recommend that lens for a budget super zoom lens.

This new lens is a bit different compared to the previous one. The build quality and finish of the lens clearly reflects the update. This lens now feels more solid and sturdy when compared to the old version of this lens.

In terms of optical quality, it seems that they are still sticking to their old 18-200mm formula. I found very minor difference between the two lenses in terms of optical quality.

The zoom ring is updated in this lens. It feels more solid and has a zoom lock mechanism to prevent zoom creep. This makes it easier to transport the lens. Many travel photographers will find this function helpful to have during their vacation.

Just like the old version, I found the autofocus fast but a bit on the noisy side. During the review, I find it hard to photograph discreetly. This might be a bit of a downside if you are into street photography.

Also, the small aperture at the telephoto end makes the autofocus hunt in low light. There is a simple solution for this: switch to manual focus. It will take time to get used to, but it will be worth the effort.

In terms of cost, it is more expensive than the 18-200mm. If you are looking for a budget super zoom lens, the Tamron 18-200mm lens is still the best option.

In terms of optical quality, this lens has low chromatic aberration and vignetting. However, I found the barrel distortion to be rather high. Note that all of those can easily be corrected during post processing using any software.

In conclusion, this lens is fine for general photography and travel photography. This can also be a fun to use lens for any professional photographers to use.
However, keep in mind that this is not a professional lens, so do not expect professional performance from it.

The Greatest Attributes Of LG Phones

The modern world with its many computerized electronic gadgets has suddenly become a very busy place and one of the new innovations that are quite useful is the cell phone. LG is therefore one of the companies in the frontline in producing some of the most reliable and functional mobile phones.

Even though this line of industry has become very competitive, LG mobile phones have been able to hold their own, and continue to produce the best when you talk about quality and cost.st.

The company started as “Lucky-Goldstar Company,” but has moved to the slogan “Life is good” as an acronym. Its origin is Korea even though people seem to think it started in Japan. It now produces goods that are marketed all over the world.

Its well known website is Ignomobile.com and apart from the cell phones, it also manufactures a great number of products that have become very marketable all over the world.

A large number of the cell phone varieties produced by LG have many great features. They are of CDMA type of phones but some are GSM models. They basically range from slip, sliders to touch screen categories.

They come in all sorts of shapes, sizes and weights to meet different tastes and requirements. Additionally they boast of features like camera, video camera, infrared, GPRS, and Bluetooth capacity.

The varieties that can be found in the market today are: TP-5200, TP-5250, VX4400, LX-5350, VX10, VX2000, VX1, VX3100L, LG3100L, LGC3320, LG KE850, LG KG200 and so forth. They also go by the names: Dynamite, Chocolate, Bullet, and PRADA.

The best part of the LG cell phones is the camera. The modern LG cell phone cameras are more wonderful than you would think because they are based on mega pixel. These range from VAP those that are of 3.5mega pixels. Some of these cameras have flash lights and lens covers that protect the lens from becoming dirty.

Tamron 11-18 Review – Tamron’s First Ever Wide Angle Lens

In this article, I will be sharing my Tamron 11-18 review. I was excited to test the first ever wide angle Tamron lens made for a cropped sensor DSLR.
I used a borrowed Canon mount to test this lens. This Tamron 11-18mm f/4.5-5.6 lens is Tamron’s first try in making an ultra wide angle lens, so you really can’t expect everything to be perfect.

First of all, the 11-18mm zoom ring might be too limiting for some people. However, remember that creating an ultra wide angle lens is not an easy feat, especially for a cropped sensor DSLR camera.

One of the reasons that I can think of on why Tamron limits the amount of zoom range is that they are trying to maintain the optical sharpness on this lens.

In addition, they might also be trying to keep the chromatic aberration, distortion and vignetting control high as well.

In terms of optical performance, there is plenty of vignetting, chromatic aberration, and distortion. They are all visible at any focal length at any aperture. Moreover, it is priced on the higher side.

Certainly not all photographers would be able to afford this lens at this price. Maybe in the future, Tamron can release the upgrade of this lens and market it as a budget super wide angle lens instead.

The build quality is pretty good, the mechanical parts such as the zoom ring and focusing ring are smooth. This certainly helps for landscape shooters who take their equipment to extreme degrees.

That being said, I would not recommend any photographers to bring this lens to below zero temperature as I do not believe this lens will survive such condition.
I am a photographer who believes that optical performance is of the utmost importance in a lens. Given that this is Tamron’s first try in making an ultra wide angle lens, I certainly believe they can learn several lessons with this first release.

I hope that on their next lens release, Tamron will improve on their optical characteristic while maintaining the good and solid build quality from this lens. In addition, they might also add the zoom range.

Many lens manufacturers have produced lens in the same league with longer zoom range.

Given the amount of competition for an ultra wide angle lens out there and Tamron’s resilience on delivering a solid product, I believe Tamron can outperform their competitors in the near future.
