What is an IP camera?

What is an IP camera, and what are the main differences between an IP camera and a CCTV camera?

IP camera, or Internet Protocol camera is also called Network Camera, and they are widely used for residential and commercial purposes, offering the user high quality.

IP camera needs a static IP address for the router and other network devices to identify and connect with it. In case of a dynamic IP address that keeps changing randomly every time the camera is connected to the network, a fixed URL via Dynamic Domain Name Service (DDNS) must be set up.

While CCTV cameras transmit one-way analog data with the help of coaxial cable to the DVR, and then it is converted to digital data, IP cameras are able to send and receive, that is to stream digital video, PoE - a system that passes electrical power along with data on an Ethernet cable., and in this case there is no need in analog to digital conversion. IP cameras stream the video directly to the NVR, a Network Video Recorder. The main advantage of IP camera over CCTV is that the camera captures and delivers a higher quality video. Additionally, IP cameras capture a much wider field of view than comparable analog cameras. As a result, the cost of IP cameras is much higher than that of analog ones.

IP cameras either have wired or wireless connections, and are used both indoors and outdoors, during the day and at night.

There are two kinds of IP cameras:

Centralized IP cameras

These cameras require a central NVR to store the recording, handle video and alarm management.

Decentralized IP cameras

Decentralized IP cameras don’t need a central NVR, and the video is processed at the source, as the cameras have recording function built-in and can thus record directly to any standard storage media, such as SD cards, hard disc, or a server.

What is WDR - Wide Dynamic Range?

WDR is the abbreviation used for Wide Dynamic Range. WDR is the technology used on professional security cameras, where there is need to balance brighter and darker surveillance areas. WDR is actually the difference in lighting. It is clearly seen, when recording entrance, where bright outdoor light is merged with dim indoor light, or when the area has large glass windows. Cameras using Wide Dynamic Range technology are able to record clearer details in low light scene, while making sure that the highlights don't get blown-out, and as a result having natural looking shot.

WDR technology is commonly used in surveillance cameras and in some medical applications. In an area with extremely bright and dark parts or in back light situations when the light comes from the back of a person, standing in front of a big window, a camera without WDR would produce an image where objects in the dark areas are hardly visible. Wide dynamic range solves this issue by applying techniques such as using different exposures for different objects in a scene for making objects in both bright and dark areas more visible and clearer. 

At www.koacctv.com high quality professional security cameras with true WDR are offered to re-sellers and installers, some of the cameras You can find below.

Security Cameras as Crime Deterrent

We have already discussed the importance of using CCTV cameras in public places, and first of all the role of CCTV cameras as crime deterrent. In this article we will find out, what do we mean by saying crime deterrent?

The most important thing is, that the cameras are an effective tool in reducing crime if deployed the right way. Correct installation, monitoring and maintenance of the cameras plays a key role in crime prevention. The use of CCTV Cameras can be a solution to issues like vandalism, drug use, drunkenness, racial harassment, sexual harassment, anti-social behavior.

It is very important to let the society know about the use of security cameras at certain area. The offender must be aware of the cameras' presence. There should be put special signs for cameras, and as different studies and statistics show, crime rate has decreased in areas, where warning signs were put. Actually, it is not so important to arrest the criminal, but it is of more importance to prevent the misbehavior. Sometimes it is even possible that fake cameras could achieve the same preventative aim as active systems. Anyhow, there might be cases, where hidden cameras should be used, because of some really important security matters, or when the police is carrying out an investigation.

Video evidence not only helps police investigate crimes, it can be used as evidence in court.

Internal cameras are meant to keep the employees honest and identify those who are not. Internal cameras can also prevent shoplifting and armed robbery and they can identify those who commit crimes despite the cameras.

An integrated security system that includes surveillance cameras is a must have nowadays, especially in areas which have high criminal rate.

So, Video Surveillance aims to:

1. deter Crime

2. increase the confidence in public safety

3. increase the property protection status

4. help police with its investigations

5. prevent social misbehavior

Different Types of CCTV cameras, Main Features.

Very often we are asked “What camera should we choose?” “What is the difference between Dome & Bullet Cameras?” etc. In this article we will describe every type of camera briefly.

CCTV cameras come in various types, styles, and configurations, and it is very important to choose the right CCTV camera for the right location and application.

Dome Cameras

In general, Dome Cameras are used for indoor security and surveillance applications. The cameras are named so, because of their dome like shape. The "dome" shape makes it difficult to tell the direction that these cameras are facing, and thus are ideal for deterring criminals. Dome cameras can be fitted or embedded to ceilings to conceal the majority of camera’s casing.

Bullet Cameras
Bullet cameras are easy to recognize by their thin and cylindrical design. There are also classifications of Ultra Bullet distinguished by their smaller size and cheaper price. These type of

cameras are ideal for surveillance of a large area, like large retail stores, houses or other business.

Unlike dome cameras, bullet cameras are easy to tell, where the camera is pointing and what it is recording.

Day/Night Security Cameras


Day&Night security cameras usually operate in two modes: colour for daytime, when light levels are high and black and white for viewing in low-light environment. A true Day/Night camera will have an “IR-cut filter” inside the camera. Once the IR cut filter is removed from the surveillance camera, it enables the image sensor to become sensitive to near-IR wavelengths, thus making it possible for the camera’s light sensitivity to reach down to extremely low light levels or even complete darkness.



Vandal-Proof Security Cameras

Vandal proof security cameras are equipped with a metal housing that prevents the camera from damage from vandalism, physical abuse or possible maltreatment. All homes or businesses should strongly consider vandal proof security cameras for their video surveillance system installation. Vandal proof security cameras are often utilized in high-security areas like warehouses, banks, airports, hotels, parking lots, and retail stores.

You can also typically find vandal-proof cases that are designed to protect more sensitive cameras, giving you the protection that you need without having to go out and purchase a brand new camera



IP/Network Security Camera

An Internet protocol camera, or IP camera, is a type of digital video camera commonly employed for surveillance, and which, unlike analog CCTV cameras, can send and receive data via a computer network and the Internet.

IP cameras, both hardwired and wireless, 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.

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.

PTZ Security Cameras



PTZ Security Cameras allow you to control the pan, tilt and zoom operations of the camera lens remotely. PTZ Cameras have the ability to move up, down, right, left, and even zoom.

HDTVI cameras

Image result for HDTVI cameras HDTVI (High Definition Transport Video Interface) is latest HD analog video solution. HDTVI can provide HD video up to 1080P resolution at real time. Different from HD-CVI and HD-SDI solutions, HDTVI can support long distance video transmission.

HDSDI cameras

HD-SDI CCTV cameras, also known as HD security cameras, are capable of capturing video surveillance footage at 1080p resolution (1920 x 1080 pixels). These high definition surveillance cameras must be used with an HD-SDI surveillance DVR.

Hidden Cameras

A hidden camera or spy camera or security camera is a still or video camera used to record people without their knowledge. The camera is "hidden" because it is either not visible to the subject being filmed, or is disguised as another object.
