AHD technology or Analog High Definition Technology

The market of video surveillance systems offers  vast choice of security systems and solutions. All of them are based on different technologies, such as HD-TVI, HD-SDI, HD-CVI, AHD technology. The consumer has wide opportunities to choose the most relevant one.

In this article, we will speak about AHD (Analog High Definition) technology. This technology is a relatively new one in the market. Anyhow, it has managed to gain great popularity in short time, because of its appealing features for end-users.

Explained simply, AHD technology uses coaxial cable for transmitting HD/Full HD video, audio, and the control signal from the security camera to the Digital Video Recorder-DVR without any latency or loss at the distance of 500 meters. One interesting feature typical to AHD, that the quality of coax cable doesn’t play any significant role for transmission. That’s why any coax cable is suitable.  AHD supports 720p and 1080p HD video resolutions. AHD security cameras deliver either 1080P HD or 720P HD clear sharp images.

One of the advantages of AHD technology is that AHD video recorders can work in three formats. Therefore with three types of video cameras: standard analog D1/960H, AHD and IP. Due to this smart feature, you can connect already installed IP or/and standard analog video cameras to AHD video recorder.

Like HD-TVI, AHD technology is also an open technology, which allows a customer to choose AHD equipment of different manufacturers because they are compatible with each other due to the same technology used.

Here we want remind our readers once more that CVI, AHD and TVI technologies aren’t compatible with each other. In this case, if you already used AHD cameras you should use AHD DVRs. TVI cameras will not work with CVI DVRs and vice versa.  AHD security systems gained popularity, as they have rather an affordable price while offering high-quality images. Easy operation is also one of the benefits: they are easy to use, plug & play, therefore no encoders, converters or switches are required. Installers with limited experience of IP network systems can easily cope with the installation process. AHD cameras and DVRs are installed using the same coax cable as traditional analog CCTV cameras. Some end-users prefer to use UTP cables such as CAT5, CAT5e, or CAT6 and get a transmission distance up to 1000 feet.

Samsung Wisenet Security System and Solutions

Samsung offers consumers and security professionals a new, affordable, high quality, easy to use security systems. AHD technology connects the high resolution of HD technology with the easy installation process of analog systems.

Samsung Wisenet line security cameras incorporated AHD technology, thus enabling to deliver superb quality HD images over coaxial cabling.

WiseNet HD+ cameras and DVRs appeal to end-users who are eager to capture and record Full HD 1080p images, but they don’t want yet to migrate from analog to an IP network based video surveillance solution.

7 Important Features Of Security Cameras

Considering buying a security camera? Want to know what is most important, what features the cameras should have? In this article we’ll discuss some of them, which make the camera better, more professional, more effective and worth buying.
Security cameras are an essential part of your home and business, and this is the case, when quality means safety.

#1 Video Quality

In the security camera business, the video quality produced and recorded by your system is very important. Now, security cameras offer at least 720p resolution, and many even offer as high as 1080p for recording and streaming. Some of the top surveillance systems on the market feature 1280x960-pixel camera resolution and more.

The main purpose of a surveillance security system is to capture or deter criminals when there is suspicious activity around the house, business, or personal items. When a crime does occur, a high-resolution camera can provide a clear and detailed picture of the criminal.

#2 Vandal-proof 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.







#3 Weatherproof Cameras

Weatherproof cameras feature at least an IP66 weather rating, which is a standard rating of protection offered by a camera’s enclosure. Each outdoor camera housing is constructed to keep out small particles such as dust, and is unaffected by a range of weather conditions including heavy rain and snow.

#4 Viewing Angle

Viewing angle is an important feature to consider when both purchasing and installing security cameras. The viewing angle will determine where you position the cameras and exactly how much they can see at a time.

For instance, a 180° megapixel camera could be used to monitor a parking lot adjacent to the building that it’s mounted on. Actually, this one camera could take the place of up to four analog security cameras.

A 360-degree fisheye and panoramic security camera provides 360° surround view without blind spots, and it is ideal for surveillance applications that require wide area coverage in a single view.





#5 Remote Monitoring / Web Access


This is not only a feature and a service that is just generally added to your overall video surveillance system, it’s also a way to manage and oversee your business from a distance. You’d better buy a camera that can be accessed via the Web. You’ll be able to see the yard, the front door or your workplace from the screen of your smartphone or laptop computer.

#6 Recording / Storage

A security camera that doesn't save or record what it captures isn't very effective, especially if you're hoping to prosecute an intruder. That's why most security cameras offer either local or cloud storage and sometimes, both.

#7 Low-Light Security Cameras / IR


Infrared security cameras capture video in low light and no light areas. IR cameras, or infrared cameras are also known as Night vision security cameras. Infrared cameras have IR LEDs positioned around the outer edges of the camera lens which gives the camera its Night Vision capability.

Dummy Cameras: Security or Illusion?

Have You heard of dummy cameras? Of course, as it is rather common to use them in surveillance purposes, when one cannot afford buying a real security system or security cameras. Dummy security cameras imitate the appearance of real cameras and there are cases when they really help to deter crime. Installing fake security camera is surely a better idea than having no security cameras at all, or trusting the property security to a dog.

 Nowadays, fake security cameras are available in different sizes, colors, shapes. In most cases they use the original housing. There are dummy cameras which have some features like a fake pan/tilt/zoom, or red lights which make the camera look more realistic and achieve better results. Of course dummy cameras have the advantages of being much cheaper, they don’t need any maintenance and in certain situations they are useful. But before buying a dummy security camera, you should review all pros and cons seriously, and make the right decision. You should understand, that when it comes to security and protection of what is dear to us, fake cameras are a great risk. 

In most cases burglars and criminals are capable of telling the difference between a fake and dummy camera at one glance. As the 80-90% property crimes are being planned beforehand, the cameras, burglar alarms and other deterrents are also checked beforehand. Always remember, that a real security camera is a safer bet than a fake one. Besides, when something bad happens to Your property or business, you will not have a surveillance footage, if you had have chosen fake security cameras. The use of fake security signs and stickers is also a bad idea, as it takes only a few minutes to google the company name and find out, whether your house is secured by that particular company or it is a fake.

It's not a good practice from a security point of view or, when used for business, from a business point of view. Besides, dummy cameras may mislead other people in that certain area of “Surveillance” into fake sense of security, thus resulting in potential liability issues for the location owner in case of accidents. 

Installing fake security cameras is a bad idea, especially when the property is located in high crime areas, if you have valuables, which should be well protected, and of course, if the well-being and security of your family members, employees or customers matters most. Modern CCTV market offers affordable security cameras and security systems, and one should realize, that this is not the case to save or go on budget. Anyway, Hikvision offers security cameras and security solutions which fit to any budget. Hikvision offers best quality for affordable price, and this is where it stands out in the market.

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.

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.
