CCTV security system now day become so important and must have in our home or office to protect our properties, this CCTV camera security system blog will talk about CCTV technology, review, new CCTV product, opinion and tips about CCTV camera
Wireless CCTV camera have a two types, one is using normal analog cctv camera and combined with transmitter and receiver. Another types is Wireless camera, using same technology like wifi card on the laptop or pc.
The picture behind is wireless camera, using 2.4ghz frequency to transmit data ( audio and video to receiver like router). The concept it's same like wifi card, have a MAC address (*device identity), so once the device switch on, MAC address will be looking to the router, and request for the ip address. After that Router will give the ip address to the wireless cctv camera.
And for the setup wireless cctv camera, what u have to do is, install the software (normally wireless camera come with software. When the installation finish, the device should get the data ( video and audio). Normal wireless cctv camera can cover up to 200 meter range. But if u want wireless cctv camera cover range up to 200 meter, go to the branded wireless cctv camera.
What are the difference between ccd camera and dome camera? the difference is in the quality of the image sensor of both camera. A CMOS camera has a less-expensive image sensor, means low quality picture. The other benefits of CMOS are size, and low-power consumption. Most CMOS cameras can even be operated for several hours on a single 9-volt battery! The low-power consumption comes at a price however. CMOS cameras have a lower resolution and less color quality than the CCD cameras.
CCD Cameras are much more sensitive to power fluctuations, due to the fact that the CCD Sensors have 4 integrated processors compared to the one processor found on a CMOS sensor. CCD cameras usually have much better picture quality, resolution and color balance. The drawback of a CCD camera is higher-power consumption and sensitivity to minute voltage changes
CCD cameras do not like direct sunlight. That can damage the image sensor.
CCD sensors have been in mass production for a long period of time and therefor…
Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a specific, limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point wireless links. CCTV is often used for surveillance in areas which need security, such as banks and airports or military installations. In industrial plants, CCTV equipment may be used to observe parts of a process that are remote from a control room, or where the environment is not comfortable for humans. CCTV systems may operate continuously or only as required to monitor a particular event.
A CCTV system may be installed where an operator of a machine cannot directly observe people who may be injured by unexpected machine operation. For example, on a subway train, CCTV cameras may allow the operator to confirm that people are clear of doors before closing them and starting the train. Operators of an amusement park ride may use a CCTV system to ob…
