IP Security 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.

IP camera video technology transmits up to 3MP video resolution over PoE (Power over Ethernet) or Wi-Fi, allowing for cost effective and long distance high-definition video transmission. IP surveillance cameras can assist you to stay in touch with what you adore anywhere, anytime. With the mobile setup process, you will have secure access to your IP camera video stream in no time.

Type of IP Cameras
There is a wide variety of IP surveillance cameras. Let’s journey together in the different types of IP cameras available:

Box Camera
A box camera is an IP camera that is compliant and compatible with third party integrators. The box camera is optimal when you want a specific, small area that you may intend to zoom in closer on since the aim of this camera is fixed in a single direction. The camera comes with no lens, so you will need to separately purchase a mount lens. This IP camera provides cutting-edge technology and leading performance.

Dome Camera (Indoor and Outdoor Camera)
Dome camera is a type of IP camera with a dome cover. The camera is fully featured with HD camera. This camera lens can manually be directly in the desired direction. The camera features both day and night capabilities, with an infra-red that kick in low lighting places. The camera also features the P-Iris lens that makes sure a wide field that allows the background, foreground, and everything in range to be in the targeted focus. The outdoor models feature high ratings in weatherproofing and vandal proofing.

Bullet Camera
The name bullet IP camera comes from relatively small size, as well the general shape of the camera. The bullet IP camera can be used for indoor security or for outdoor security. Outdoor bullet IP cameras are typically placed high to make them less accessible and harder to reach for tampering. Like the dome cameras, the bullet cameras can be adjusted to a specific desired location. They have better zoom capabilities than the dome cameras. Bullet IP cameras are typically rated high in waterproofing, but their design makes them more vulnerable to damage as they lack enclosure design.

PTZ Camera
PTZ stands for Point-Tilt-Zoom. A PTZ IP camera is a camera that is capable of zoom and remote directional control. In television, PTZ controls are used with video cameras in sporting events, television studios, and other places. PTZ cameras can be controlled to any direction you want when you want. It features 10x digital zoom, 20x optical zoom, and a pan feature that allows you to scan a specific area.

Amcrest security IP cameras are relatively new and underdeveloped technology, but in time its improvements to encoding, image processing, and networking technology will surpass over the cost and reliability of analog cameras.

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.


Amcrest security 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
