How to choose monitoring

1. Learn about the various types of security cameras available:

Security camera. Spherical camera professional camera translation zoom camera hidden camera

2. Advantages of security cameras. This is a popular video camera suitable for business and family.

Infrared cameras produce high-resolution color video during the day. They are the preferred camera types in low or no light conditions. They can "light up this area" by automatically switching from color to black and white. Turn on the infrared illuminator, so that you can see the human eye clearly in low light and no light. Whether used indoors or outdoors, they can provide great advantages in low light or no light. They are unaffected by the weather and can withstand high and low temperatures without any additional camera housing. Indoor cameras can provide clear video images in light and darkness.

3. Advantages of spherical camera. Different styles of ball types include infrared ball type, indoor ball type, outdoor ball type, destructive ball type and pan-tilt zoom ball control type. The classic "smoked" spherical camera provides additional monitoring, because it is difficult for friends, customers, employees and thieves to see where the camera is actually pointing. Smoke screen will not affect the image quality.

A clear color high-resolution image can be obtained by using a spherical camera. Most pan-tilt zoom cameras also use dome-shaped housings. Professional "cassette" cameras use camera housings indoors and outdoors.

4. Advantages of professional cameras. These cameras are famous for their high video quality. Professional box cameras are common in banks, supermarkets, convenience stores and so on.

You can change the lens on a professional camera according to the required viewing angle and zoom. Some Pro Box cameras are called day/night cameras because they can switch from color to black and white or low lux at night (in light conditions). The lower the lux is, the clearer the camera can see in complete darkness. Infrared camera is considered as night vision camera, and its level is 0 lux. If you don't need or want infrared rays, and you are more concerned about high-quality daytime video, you may prefer a cassette camera.

5. The benefits of pan-tilt zoom camera. These cameras can be controlled by DVR, remote viewing software and/or joystick. They can move up and down, left and right. They also have a zoom function.

For example, you can capture the license plate from a distance or enlarge your face. You can also set up planned patrols for them, and you can monitor certain areas when you go out. Airports, casinos and large department stores are all places where PTZ (Panoramic Tilt Zoom Camera) is used. Panoramic zoom cameras are expensive, starting at more than 3000 yuan. The question is "Do you need a pan-tilt zoom camera", or can you use a fixed camera to get the required solution? The panoramic zoom controllable camera needs an extra cable to operate. In addition to the power/video RG-59 conjoined coaxial cable, a CAT5 cable is needed to control it in real time through the Internet. Just use the CAT5 cable next to RG-59 to control PTZ's zoom camera.

6. The benefits of hiding the camera. These can provide the highest level of monitoring. If you don't want anyone to know there is a camera, please use a hidden camera. False smoke detectors, motion detectors, clocks, sprinklers and exit signs are all examples of the types of hidden cameras used.

The main disadvantage is that the hidden camera has no infrared function, which limits its performance in low light conditions. In addition, many hidden cameras are not all-weather, so they are not as useful as infrared cameras and hemispherical cameras when used outdoors. Pharmacies, hotel corridors, assisted living facilities and homes are all examples of applications that use hidden cameras.

7. Decide whether you need a wired or wireless camera. Wired cameras provide more cameras, and more importantly, they provide better video quality than wireless cameras. Wireless cameras can be misleading because they need power at the camera location. In addition, they need a clear line of sight, which usually causes problems.

Reliability and video quality are the main reasons why you should use cable cameras. The wired camera is dialed back at DVR position, and only one cable is needed from DVR to each camera (RG-59 conjoined coaxial power supply/video integration). With this special cable, you can run the camera up to 800 feet (243.8 meters). If it is more than 800 feet (243.8 meters), you will need to use CAT5 cable with video balun and/or amplifier. The use of wired cameras has a longer life and higher quality. Wired cameras are clear. With this in mind, occasionally you may have two positions that absolutely need it. In this case, you can plug the transmitter into the back of the DVR.

8. Different types of security cameras–-AHD, HD SDI, HD CVI, HD TVI and IP.

Like high-resolution cameras, you can expect them to have the excellent quality of many other cameras on the market. Cameras above 480P (called high resolution compared with ordinary 380p and 420P cameras) have good value. Now there is an ultra-high resolution camera with a resolution exceeding 1080P. Choose a camera according to your application. Infrared all-weather spherical cameras are the most popular outdoors, while hemispherical cameras are very popular in indoor applications. All cameras are different and provide outdoor, indoor or infrared functions. To know which camera is the most popular, you can ask the buyers and installers who have used it.
