CCTV security cameras from the Dahua camera suppliers, sometimes called closed-circuit video, are the use of closed-circuit video cameras to send a video image to a particular location, usually on a restricted set of monitors. A digital camera that transmits the image is referred to as an imaging sensor, and is used to capture the images. There are different types of closed-circuit cameras, including IP (Internet Protocol), analog (analog-to-digital conversion) and digital (analog-to-digital transmission). The images are then sent to a video monitor that shows them on the monitor.
IP (Internet Protocol) CCTV security systems allow for the monitoring of a location through the Internet, which is much more secure than regular analog cameras. The axis IP CCTV camera uses the Internet to communicate with a remote site, rather than having to physically access the monitor. The main advantage of using IP cams is that the signals can travel faster and farther, which means there is less chance of transmission failure. An IP CCTV security system allows the monitoring of a wide area through the Internet. There is no need to physically access the monitor, which makes this method of monitoring much more cost-effective. However, an IP camera is vulnerable to hacking, which can be done by someone who has physical access to the IP camera.
Another type of CCTV security cameras is the CCTV system that uses closed-circuit television. CCTV closed-circuit televisions are basically a pair of cameras, or several cameras, that capture video images in real time and transfer them to a monitor over the Internet. They can be used to view everything that is going on around the property, and have advanced features such as motion detection, pan/tilt/zoom, and night vision. These cameras can offer both indoor and outdoor coverage.
A final type of CCTV security camera is called an IP (Internet protocol) video surveillance security camera. An IP video surveillance security camera works just like any other regular CCTV system, except it makes use of an IP network instead of a conventional connection. This allows the same video footage to be viewed from any location, so long as there is an Internet connection available. Most IP cameras also include advanced imaging technologies, including digital image processing and high-definition video transmission.
CCTV security systems that record footage directly to an external hard drive or to an online storage device are often referred to as DVR (digital video recorder) systems. A typical DVR system will contain one or more individual DVR cameras, a recording studio, a control interface with the Internet, a series of software programs for viewing the captured footage, and a storage device. When the footage is viewed, it is typically written over to an SD card or memory stick and saved to the computer. Some DVR systems allow the user to view the captured footage in real time, via a web cam. Other types of digital video surveillance systems allow the user to watch the footage on a personal computer, smartphone, or tablet.
Although CCTV cameras have many benefits and can help increase security, they are not all-good. Many people use surveillance cameras for fun or they may not be as effective as they claim. If you are looking for a cost-effective and easy to install CCTV security system, a wireless CCTV security camera may be your best option.
