Knowing when to use a C-Mount Security Camera in your Security System

November 18th, 2009 Steven Black No comments

C-mount surveillance cameras are the first security camera. They were developed in the’70’s and are defined to this day by their rectangular style. This shape was necessary because nearly all the circuit boards were bigger than today. As camera technology has improved over the years, camera sizes have gotten smaller allowing for designers to create additional shapes. Currently, the security camera manufacturers make a variety of camera types, the now most prominent being the bullet camera.

CS-mount cameras are still some of the most technologically advanced security cameras around, as their size allows them to always support the newest lens technology before other security cameras. As with all technological developments, when a new lens is developed the first goal is to get it created, and the next goal it to make it smaller. Because of this process, cs-mount camera are always the very first format of security camera to be able to use a new technology. Right now, that technology is 1/2 inch lenses. Almost all other security cameras can only use 1/3 or 1/4 inch lenses. The size of the chip set is important as it defines two things: how well the surveillance camera can see in low light and the maximum resolution of the camera.

C-mount security cameras are very effective when used in interior security setups, but face challenges when used outside. To be used on exterior walls , cs-mount surveillance cameras need special mounting brackets to fix them on outside walls and housings to protect c-mount security cameras from the weather conditions.

Every cs-mount surveillance cameras has a varying ability to see in the dark. To know how well the camera works in poorly lit conditions, you will need to consult it’s lux rating. A lower lux rating means that the camera will be able to operate better in lower light. Because cs-mount surveillance cameras can deliver color video in poor lighting conditions, c-mount cameras are especially valued in crime-fighting and government operations. A low lux rating usually means a more costly camera.

One should remember that cs-mount cameras do not come from the store with a lens, so one will need to be purchased separately. This makes them initially more more expensive and cheaper over time, as their lenses can be exchanged to fit another role rather than requiring a completely new camera.

The biggest negative of a c-mount camera is their difficulty in being used outdoors. If you want to use a cs-mount camera in an external environment, you will have to put the camera in a c-mount housing, which will give it protection from rain, wind, and the elements. Another piece of equipment you will need is a mounting bracket, this allows you to mount it in a variety of positions and on specialized surfaces. In very extreme conditions (very hot or very cold) a cs-mount surveillance cameras might require specialized housings with heaters or cooling fans built in.

CS-mount cameras also significantly deter crime, as their bulky shape makes them extremely noticable. As such, many banks, businesses, and government offices use them. They declare “You are being recorded.”

In summary, cs-mount cameras are the very highest quality security camera but have some challenges when being used outdoors, as they were not built for adverse weather conditions. CS-mount surveillance cameras can see better than most other cameras in low level light, can be adapted by changing out their lenses, and offer the very highest resolution of any security camera.

Full HD TV Buying Guide

September 18th, 2009 Hermione Cook No comments

With the recent explosion of HDTV, I’m sure you’ve heard of High Definition Television due to the bombardment of adverts on the TV and web. What you might not know is that not all HD TV is strictly Full HD TV. With a plethora of models available, for a true Full HD TV experience, be aware that not all TVs meet HD quality standards to allow you to get the maximum benefits of watching high definition broadcasts, Blu Ray DVDs. To be sure you know the facts about Full HD TV before buying a TV that will give you the highest viewing quality available from High Definition TV.

Variations in specification of Full HD TV sets are wide and in the beginning there can be a lot to take in. With the choice what size display, 1080p or 1080i, LCD or Plasma making a decision is not easy. The most popular size of set is probably a 42 inch TV. This size is adequate for the average living room and other big rooms. With the cost of purchasing a HD TV falling take your time to carefully decide the model most suitable for your requirements.

If youre considering a Full HD TV one of your first decisions is between Plasma and LCD sets. Full HD Plasma TV sets are known to have a better picture quality. LCD displays tend to have a longer life span than plasmas but due to improvements in plasma display quality and screen saving features, pixel burn is not really an issue and the expected viewing life of plasmas is not an issue for the average owner. Plasmas are however more expensive than their LCD equivalents.

By far the more prevalent HD technology is Full HD LCD TV. The issue of screen burn and shorter life span do not come into the equation with LCD televisions. These type of televisions have good quality pictures and refresh rates but the colours produced by plasma displays still outperform LCD TVs. Due to these qualities, Full HD LCD TV sets make it a great choice for gamers and the fast paced high detail action produced by modern games consoles. The generally cheaper prices of todays LCD TVs are also of benefit to shoppers with less to spend.

A HD TV converter is not all they are made out to be. The converter is capable transforming a high definition signal and outputting a signal that can be displayed on an old analogue television set. It can also work in reverse by taking an analogue signal and converting it as an output for a HD TV, the picture quality may be improved by the features of your Full HD TV set but at the end of the day it is still an analogue signal.

As previously discussed not all TVs that are sold as HD meet Full HD TV standards. You must be careful when making your choice of what set to purchase. Televisions sold as HD ready usually conform to the 720p specification. With 720p sets there is an improvement over standard analogue TVs but when compared to 1080p and 1080i there will be a noticeable improvement with the 1080 sets especially for larger screen sizes. 720p is not true full HD TV and is better suited to the smaller screens.

If youre in the market for a Full HD TV go for the TV sets which meet the 1080p or 1080i specifications. The 1080i specification has a 1280 by 1080 pixel resolution but the 1080p has a 1920 x 1080 pixel resolution but with the progressive scanning you will notice a smoother picture. Because of the superior quality 1080p, the price can be higher but if this takes it out of your reach then 1080i still provides a high standard of picture suitable for most viewers.

Despite looking like a complicated affair, the decisions involved in buying a Full HD TV are quite simple. If you want the best viewing experience, a television to enhance your home gaming needs, and a set to do your Blu Ray DVDs justice. Then a full HD TV is the way to go, if you do your homework and choose wisely then you won’t need a second mortgage either.
