WHAT IS CC CAMERA???

CCTV CAMERA.

Closed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint (P2MP), or mesh wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring such as banks, casinos, airports, military installations, and convenience stores. Videotelephony is seldom called "CCTV" but the use of video in distance education, where it is an important tool, is often so called.[1][2]

In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, for example when the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing digital video recorders, (DVRs), provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion detection and email alerts). More recently, decentralized IP cameras, some equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation. Surveillance of the public using CCTV is particularly common in many areas around the world. In recent years, the use of body worn video cameras has been introduced as a new form of surveillance.

সিসি ক্যামেরা কি????

সিসিটিভি ক্যামেরা সিষ্টেম এর ব্যবহার আমাদের দেশে দশ-পনের বছর আগে শুরু হলেও পশ্চিমা দেশগুলোতে আরো বহু আগে থেকেই ব্যবহৃত হয়ে আসছে। যদিও সিসিটিভি ক্যামেরা সিষ্টেম তখন ছিল শুধু সাদা-কালো, এসব ক্যামেরায় অল্প আলোতেই পরিষ্কার ছবি দেখা যেত। পরবর্তিতে রঙ্গীন ক্যামেরা বাজারে আসলেও স্বচ্ছ ছবির জন্য প্রচুর আলোর প্রয়োজনীয়তার কারনে ব্যবহার সীমিত হয়ে পড়ে। বর্তমানে প্রযুক্তিগত উন্নয়নের ফলে অনেক কম আলোতেই রঙ্গীন ক্যামেরায় পরিষ্কার ছবি দেখতে পাওয়া যায়। ফলে এখন আর সাদা-কালো সিসিটিভি ক্যামেরা বা সিষ্টেম উৎপাদন হচ্ছেনা। বর্তমান চাহিদা অনুযায়ী দুই ধরনের রঙ্গীন সিসিটিভি মনিটরিং সিষ্টেম বাজারে পাওয়া যাচ্ছে। ষ্ট্যান্ড এ্যালোন এমবেডেড ডিভিআর (ডিজিটাল ভিডিও রেকর্ডার) সম্বলিত সিসিটিভি মনিটরিং সিষ্টেম এবং পিসি বেজড সিসিটিভি মনিটরিং সিষ্টেম। ব্যবহারের ভিন্নতার কারনে বর্তমানে রঙ্গীন সিসিটিভি ক্যামেরা বিভিন্ন প্রকারের হয়ে থাকে। যেমনঃ সাধারন ক্যামেরা, ডোম ক্যামেরা, হিডেন ক্যামেরা, স্পাই ক্যামেরা, স্পীড ডোম পিটিজেড ক্যামেরা, হিডেন ক্যামেরা, স্পাই ক্যামেরা, ডে-নাইট ক্যামেরা, জুম ক্যামেরা, ভেন্ডাল প্রুফ ক্যামেরা এবং আই পি ক্যামেরা উল্লেখযোগ্য।

A CCTV security system is essential for any type of business or public organization. Therefore it’s vital to select the right CCTV camera for the right location and application.

There are lots of CCTV cameras to choose from on the market today, with many different features and options, resulting in a confusing array of various types, styles, and configurations. But which is best for your intended business security application?

Here Are The 8 Different Types Of CCTV Cameras You Should Know About:

1. Dome CCTV Camera

Dome CCTV Cameras are most commonly used for indoor security and surveillance applications. Dome cameras get their name from the dome-shaped housing in which they sit. These housings are designed to make the CCTV cameras unobtrusive… not covert or hidden. Typical applications are retail, where the camera is designed to be unobtrusive, but visible.

The "dome" shape makes it difficult to tell the direction that these cameras are facing, and thus are ideal for deterring criminals. The “bad guys” will know the facility is being watched and customers will feel at ease knowing the facility is being protected.

2. Bullet CCTV Camera

Bullet CCTV Cameras have a long, cylindrical, and tapered shape, similar to that of a "rifle bullet", often used in applications that require long distance viewing. The camera is not typically designed to have pan/tilt/zoom control but instead to capture images from a fixed location, pointing at a particular area.

A bullet CCTV camera is a wall-mount or ceiling-mounted unit that is typically designed for indoor use, but can also be used for some outdoor applications.  Many bullet cameras can also be waterproof by being installed inside protective casings, which protect against dust, dirt, rain, hail and other harmful elements. 

3. C-Mount CCTV Camera

C-mount CCTV cameras have detachable lenses to fit different applications. Standard CCTV camera lenses can only cover distances of between 35 and 40ft, therefore with C-mount CCTV cameras, it is possible to use special lenses, which can cover distances greater than 40ft.

4. Day/Night CCTV Camera

The day/night CCTV cameras have the distinct advantage of operating in both normal and poorly-lit environments. These cameras do not have Infrared illuminators because they can capture clear video images in varying light conditions and in the dark.

The camera is ideal for outdoor surveillance applications, where Infrared CCTV cameras cannot function optimally. These CCTV cameras are primarily used in outdoor applications and they can have a wide dynamic range to function in glare, direct sunlight, reflections and strong back light 24/7.

5. Infrared/Night Vision CCTV Camera

These night-vision CCTV cameras have the ability to see images in pitch black conditions using Infrared LEDs and are ideal in outside conditions where lighting is poor to zero.

6. Network/IP CCTV Camera

These cameras, both hardwired and wireless, transmit images over the Internet, often compressing the bandwidth so as not to overwhelm the web. IP cameras are easier to install than analog cameras because they do not require a separate cable run or power boost to send images over a longer distance.

7. Wireless CCTV Camera

Not all wireless cameras are IP-based. Some wireless cameras can use alternative modes of wireless transmission. But no matter what the transmission method, the primary benefit to these units is still the same: extreme flexibility in installation.

8. High-Definition HD CCTV Camera

Ultra high-definition cameras are often relegated to niche markets, such as casinos and banks. These give the operators the ability to zoom in with extreme clarity (to look at a poker player who might have something up their sleeve).

Beyond this list, there are many other types of CCTV cameras, but most of those are more related to the application in which the unit will be used vs. the type of camera.
