The New Camera Technology - IP Cameras



An IP camera, or Internet protocol camera, is a type of digital video camera employed for surveillance. Unlike analog CCTV (Closed Circuit Television) cameras, IP cameras can receive and send data via the internet or a computer network. Although a majority of the cameras that do this are webcams, the phrase “netcam” or “IP camera” is normally applied to those used for surveillance. 



There are two types of IP cameras. Centralized IP cameras and decentralized IP cameras. Centralized IP cameras require a central NVR (Network Video Recorder) to handle the video, recording and alarm management while the decentralized IP cameras do not require a central NVR, this is because the cameras have a recording function built-in and thus making it record directly to any storage media such as PC/server, network attached storage or SD cards.

Though IP camera is a new technology which has developed quickly in the recent years and even threatens the market of the analog security camera, many customers hold some kind of suspicion about it. In this article, the author illustrates the advantages and disadvantages of IP cameras so as to grasp a better understanding of IP cameras.

The advantages include:

High Image Quality

Image quality is clearly one of the most important features of any camera. Superior image quality enables the user to closely follow changes and details in images, making way for faster and better decisions to more effectively safeguard people and property. It also ensures greater accuracy for automated analysis and alarm tools.

Flexible and cost-effective

Using standard PC server hardware radically reduce equipment costs, particularly for large systems where servers and storage have a significant portion of the total solution cost. IP-based systems provide a means for network video products and other types of applications to share the same wired or wireless network for communicating data.

Remote accessibility
IP cameras can be monitored timely from any computer anywhere in the world, and from many mobile devices including iPhone, laptops, etc.

Encryption and authentication

IP cameras offer the transmission of data through authentication and encryption methods such as WPA, WEP, WPA2, AES, and TKIP.

IP cameras post some disadvantages which may include:

  •  High initial price for high-quality cameras.
  •   Lack of standards. Various IP cameras can encode video differently or use different programming interface, which may require camera recorder combination.
  •   Technical barrier. IP camera requires IP address, network settings, and DDNS, for this services one should hire a specialized technician who is familiar IP cameras.
  •   Network traffic requirement is high. A simple IP video in MJPEG mode requires about 3 Mbit / s.


IP cameras are used in an unlimited number of places; however, most of them fall under the security surveillance or remote monitoring of people, property, places and operations. Some typical place that has applied IP cameras includes retail sectors, schools, industries, banks, government offices, etc.

IP camera is relatively new and underdeveloped technology, but in time its improvements to encoding, image processing, and networking technology will surpass over the cost and reliability advantages of analog cameras

Wireless Security Cameras



Home and business security has moved a step ahead in terms of surveillance cameras. Wireless security cameras are CCTV (closed-circuit television) cameras that send audio and video signal to a wireless receiver mostly through a radio band. The cameras require at least one cable for power, thus the term “wireless” refers to the transmission of audio or video data. However, some cameras are battery powered making them totally wireless. In this article, the author will focus on the types and applications of wireless security cameras. 



Wireless security cameras are becoming very popular among modern security customers due to their low costs in installation (there is no high demand for running video extension cables) and flexible mounting options. There are two different types of wireless security cameras: Digital wireless cameras and analog wireless.

Analog Wireless

Analog wireless is the transmission of video and audio signals using radio frequencies. Normally, an analog wireless transmits data around the range of 91 meters in open spaces. Doors, furniture, and walls will reduce this range. Analog wireless is found in three frequencies but a majority of wireless security cameras operate on 2.4 GHz frequency. Household routers, video game controllers, microwaves, and cordless phones operate on this same frequency. This may bring interference with your wireless security camera.

There are several advantages that come with analog wireless.
Ø  It is cost effective since the cost of an individual camera is low.
Ø  A signal from a camera has multiple receivers. The signal from one camera can be received by any receiver. You can place several receivers in various locations so as to generate a wireless surveillance network.
Here are some of the disadvantages:
Ø  It has no strength indicator. There is no any visual alert indicating the signal strength.
Ø  One-way communication. The receiver will receive data from the camera but the receiver cannot send the signals back to the camera.
Ø  Interference from household devices such as video game controller, microwave, and cordless phones. 

Digital Wireless Cameras

Everything nowadays is going digital including the cameras. Digital wireless is the transmission of video and audio analog signals encoded as digital packs over high bandwidth radio frequencies. The digital wireless camera has several advantages:
Ø  A wide transmission range. It is commonly observed on open space between the receiver and the camera.
Ø  High-quality audio and video.
Ø  Functions and commands, such as playing music can be transmitted.
Ø  Multiple receivers can be connected to one recording device.

Uses and applications

Home Security Systems
Wireless security cameras are becoming the talk of the town in the consumer market since it is an effective way of having a comprehensive surveillance system installed for a less expensive price. The cameras are ideal for people renting apartments since there is no need to run extension cables through ceilings or walls. Additionally, lack of wiring avoids damage looks on a building.

Barn Cameras
Wireless signals can be transmitted from one building point to another in places where it is not possible to run wires due to obstacles. A common use of these is watching a barn with animals.

Law Enforcement
Wireless security cameras are used by law enforcement agencies. They use these cameras to deter crimes.  The cameras can be installed in many locations and data transmitted through government wireless network.

Wireless security cameras work best when in an open clear line of sight between the receiver and the camera.
