Writer:ANBOSONDate:2017-09-14

It’s known that popularity of video surveillance systems is on the rise and they appear in our life from traditional shopping malls to roads and currently it’s more and more popular to see them in houses. What matters is now how we can choose a most suitable and cost-effective video surveillance solutions.

 

1. CCTV camera types:

 

Different types of cameras mean different video surveillance area. PZT camera is usually applied in some wide-range places because PTZ camera can support 360 degrees horizontal rotation and 90 degrees vertical rotation with multiple optical zoom function. Panoramic camera is also popular in the market as it is a 360-degree seamless surveillance equipment and also equipped with pan/tilt and zoom function. For some areas like office and store, one panoramic camera is enough as it can replace 4pcs traditional cameras. If surveillance area is small, you can just choose ordinary camera

 

2:Camera lens

 

With shorter lenses, a wider portion of the subject will be in the image and vice versa. Based on different applications, there are wide-angle lens (>90 angle degrees), normal lens(30 angle degrees more or less),telephoto lens(within 20 angle degrees with focal length ranging from tens of millimetres to hundreds of millimetres ),varifocal lens (focus length is interchangeable and it can change into telephoto lens from wide-angle lens) as well as pinhole lens(usually hidden well).

 

3:Applications

 

Nowadays most of cameras are suitable for both outdoor and indoor installations. For outdoor application, waterproof performance is required. For some extremely cold places, camera stability is a significant factor to consider and cameras should be provided with built-in heater inside in order to use it normally at a very low temperature. Dust-free protection design is very important for CCTV cameras applied in some industrial applications like factory and CCTV cameras installed in restaurant kitchen should have a good oil and soot resistance performance.

 

4:Resolution

 

How much resolution cameras should be chosen depends on specific video surveillance size. For example, high resolution cameras are suitable in some wide-range areas to ensure clear image quality when image is enlarged. It’s true that high resolution cameras are not necessary for all applications. In places like offices and reception rooms, low resolution camera can be taken into consideration. 

 

5:Video surveillance area

 

Different types of cameras mean different video surveillance area. PZT camera is usually applied in some wide-range places because PTZ camera can support 360 degrees horizontal rotation and 90 degrees vertical rotation with multiple optical zoom function. Panoramic camera is also popular in the market as it is a 360-degree seamless surveillance equipment and also equipped with pan/tilt and zoom function. For some areas like office and store, one panoramic camera is enough as it can replace 4pcs traditional cameras. If surveillance area is small, you can just choose ordinary camera 

 

6:Video storage time

 

Surveillance video is usually stored for one month based on industry standard. IP surveillance video takes up more space on the HDD. (For example, 1.3MP camera space usage is 21G/day/CH and it is 40G/day/CH for a 2MP camera) In this regard, the length time of video storage can also be kept for one week or two weeks if total budget is limited.
