Choose to buy a security camera system - PC World VN
Identify needs
Put the needs of system security camera torchlight 2 classes that you want to invest installed by posing a series of questions. First of all, you need a tracking system or just one single camera torchlight 2 classes consists of 2, 4, 8 or 16 camera? Do you want to see clearly the face of people, goods, or the details of the video? You need a security camera system wireless or wired? You need a camera system mounted indoors or outdoors? Should choose analog or IP camera technology camera? Your budget is limited to how much? Based on demand, the environment and the camera is the most important economic possibilities which you can choose the most suitable camera.
After determining the needs of your security system how many cameras, it is equally important that you need to do is determine where to place the cameras and purchase accordingly. You need cameras for outdoor torchlight 2 classes use or just select the type usually associated in the house. The camera mounted outdoor samples are often designed with features to withstand more extreme weather conditions such as anti-dust, rain, temperature ...
The camera is capable of recording samples night thanks equipped with infrared torchlight 2 classes light. Besides, define system monitoring your camera works only during working hours of the day or at night. That way, you can plan to invest for cameras capable of shooting torchlight 2 classes at night with infrared lighting.
An important step to take is to examine the place of installation before the camera to determine the type of camera to buy wired or wireless. If the installation location allows wired and wireless network resources easily, conveniently, you can choose torchlight 2 classes a wired camera. Conversely, if the installation location is not convenient to go wireless network, choose the type of wireless.
Wireless cameras are often used in the home, easy to install and provides the flexibility to change the camera position without running new wires. With the larger environment or in the business may need a more complex solution, wireless camera is a more appropriate choice.
Analog security camera technology often post pictures analog (analog) to the DVR. Meanwhile, the IP camera will store images of digital signal (digital) via a local network or the Internet. IP camera technology torchlight 2 classes will help you make the transmission more efficient because each camera will broadcast under their own IP address.
IP camera is also rated higher resolution than analog cameras. Businesses often available local IP network, thereby investing IP camera system may be an option to save considerable cost to purchase additional hardware or cables.
In addition, the IP camera is also rated higher resolution than analog cameras. torchlight 2 classes Therefore, if the element image clarity and ability to capture the motion is critical for security camera systems can, the analog camera may not be the ideal choice. IP cameras are also less susceptible to interference torchlight 2 classes from other wireless devices.
Most security torchlight 2 classes cameras are now used chip CMOS image sensor or CCD (Charge Couple Device). Small and analog cameras often use cheap CMOS technology, providing poor quality images and video with very low sensitivity.
Meanwhile, the analog camera model quality and higher prices using the CCD sensor. CCD chip sizes are usually 1/4 inch, 1/3 inch or 1/2 inch. Technically, the larger sensor torchlight 2 classes size, the offer higher image quality and higher prices.
It all depends on your needs and the size of the screen to keep track of you. The camera has higher torchlight 2 classes resolution, the image will be sharper and more detailed. The secondary camera on the market
