Each of these cameras has special features and unique strengths. CCTV cameras are used to identify criminals outside the home or to monitor the furniture inside the home and workplace. To choose your desired CCTV camera, you should consider the following 3 important factors:
💠 Suitable lens 💠
The right lens guarantees the right quality. Choosing the right lens will make the camera zoom and focus correctly on the objects and the sensor will absorb enough light. In this way, the details of people's faces can be recognized and the license plates of cars can be seen clearly.
💠 Suitable Sensor 💠
To choose the right sensor, two important parameters "size and type" should be considered. These sensors are of two types: CMOS and CCD. CCD is more expensive and the image produced by them is of higher quality than CMOS, so it is more suitable for face recognition and license plate recognition.
💠 appropriate output resolution 💠
The more pixels an image has, the better the details of the image can be seen when zooming. The maximum resolution of CCTV cameras currently in the market is 700TVL. But most of today's CCTV cameras are in the range of 300 to 550 TVL. Perhaps the most important parameter for choosing a CCTV camera is that its resolution matches your needs and use, so you should pay close attention to this.
