Wireless IP cameras record and send images to one or more computers over a wireless network. They allow users to view live feeds from remote locations, or save them onto a hard drive or removable media for later viewing. They usually have more features than CCTV cameras, such as pan, tilt, and zoom functions. In security and surveillance applications, they are often used with advanced software, such as motion detectors, which can trigger alarms or alert authorities when suspicious motion is detected.
Types of Wireless IP Cameras
Kinds of Wireless IP Cameras include the following:
CCD IP cameras
Charge coupled device (CCD) cameras have better light sensitivity and are used to film in low light conditions.
They tend to “bleed” or create or form vertical stripes around very bright objects.
They are usually more expensive and use up more power than CMOS cameras.
CMOS IP cameras
Complementary metal oxide semiconductor (CMOS) cameras convert charges directly on the sensor to prevent bleeding or leakage.
They have lower operating temperatures and require less battery power.
They can convert analog feeds to digital signals and can easily switch between sources.
Choosing Wireless IP Cameras (Buying tips)
Security: Choose a wireless IP camera that operates at a high frequency to avoid congestion and with other wireless devices. Make sure it has encryption capabilities to keep images from getting intercepted during broadcast. Look for additional security features like password protection and firewall support.
Frame rate: Choose a wireless IP camera with a frame rate of about 30 frames per second (fps) for fast, smooth motion. Slow frame rates can cause choppy images and may not capture fast movements accurately.
