Wireless IP Surveillance Cameras
What is an IP Camera and How Do They Work?
Wireless Home Monitor are an innovation of modern Surveillance systems. It is a digital video camera commonly used for surveillance purposes. It sends and receives data via a computer network and the Internet. Although most cameras that do this are web-cams, the term "IP camera" is usually applied only to those used for surveillance.
An IP Camera (short for Internet Protocol) is a stand alone camera that connects to an IP network such as a LAN (Local Area Network) or the Internet. Through the network, the camera can stream video that can be accessed remotely, either by other computers on the network or via web based devices such as iPhones and iPads via the Internet. These network cameras are typically wired (meaning they require a network connection) or wireless.
A wireless home camera is viewable anywhere in the world that you have Internet access. This can be be done on a laptop computer, iPad or Android tablet, or any smartphone with web access like an iPhone or Blackberry.
What Are Some Cool Features of IP Cameras? What Should You Look for When Buying an IP Camera?
Not all IP camera are the same so you should do a bit of research before making your purchase. Pay particular attention to any specification tables, as certain product specifications may dictate why a camera is priced inexpensively or not. Here are a few features to consider:
Lens
The larger the lens, the better image you will be able to see, particularly for outdoor cameras, where you want the best possible image at even great distances. Most indoor IP cameras have a 3.6mm lens, which is adequate for their intended use. Outdoor IP cameras have anywhere from a 6mm to a 12mm lens.
Resolution/Image Compression
Resolution and image compression are factors in the clarity and size of the images the IP camera can deliver. A standard IP camera provides 640x480 pixels with an MJPEG image compression. These are great for viewing who is at the door or how your pet is doing.
If you need better images and video, consider an IP camera that uses H.264 video compression, which is high definition video in narrow bandwidth networks. These cameras tend to be more expensive, however the images and video are very clear.
Pan/Tilt/Zoom
Pan, tilt and zoom (often called PTZ) reflects the movement options of the IP camera. Pan refers to the rotation of the camera in a horizontal plane. Tilt, on the other hand, refers to the rotation of the camera up and down. Zoom, much like a standard camera, describes the varying of the focal length of the lense to either make the image appear closer or further.
Outdoor cameras tend to have a fixed position, while indoor cameras can offer pan/tilt or pan/tilt/zoom.
IR LEDs
If you are interested in using your IP camera for night vision, then you should pay particular attention to the number and strength of the IR (infrared) LEDs on the cameras you are researching. The LEDs allow the camera to illuminate the viewing area in darkness. The more LEDs - the brighter the viewing area - the better the image. This also allows you to view greater distances in the dark.
Two-Way Communication
The ability to see and hear video is very important for some ip camera applications. If a camera has two-way audio, then it is not only capable of allowing you to hear what is happening at your camera, but will also allow you to speak through the camera's speaker. Some cameras will say "two-way audio capable" which means it has jacks for an external speaker and microphone.
Advantages of Wireless IP Surveillance Cameras:
Video Surveillance with wireless security monitor has made life and property a lot safer. Any household or businesses with proper Video surveillance is like a fortress that cannot be penetrated by intruders. These wireless IP camera are like the eyes of any security system; even our governments are using it to protect us from any unprecedented threats.

Advantages of Wireless IP Surveillance Cameras:
- It has a two-way audio system via a single network of cable that allows users to communicate with what they are seeing.
- The flexibility of these IP cameras gives it an upper hand over other surveillance cameras. It can be moved around anywhere on a wireless network.
- IP cameras allow video analytics to be placed in the camera itself that equips it with the ability in analytics solutions.
- Commands for camera movements such as pan, tilt, or zoom can be given to these IP cameras via a single network.
- Wireless IP cameras offer secure data transmission through encryption and authentication methods such as WPA, WPA2, TKIP, and AES.
- Wireless IP cameras used in Surveillance can be remotely accessed. Live video from selected cameras can be viewed from any computer, anywhere, and also from any smart-phones and other devices.
- Modern Wireless IP Cameras have the ability to operate without a power supply. They can work with the Power over Ethernet protocol.
- IP camera communication signals are not just electronic voltage; it is numerically decoded as bits and bytes with security features and TCP/IP protocol.
