Varifocal Lens Waterproof IR wireless CCTV Camera

Q:Monitor the camera, how much money one, the kind of video: 20 meters of infrared one machine, domestic Sharp Rui tablets, between 180-300, SONY Rui film, between 200-400, which means that night vision can reach 20, if you are not demanding on the night, but the day See it, it is cheaper, Sharp Rui film 150, SONY Rui film 180. Give you a price, do not require the price of night vision.

Q:What does the privacy of the surveillance camera cover?: 4, infrared day and night camera: the camera, protective cover, infrared light, power supply unit integrated into one of the camera equipment, with night vision distance, hidden strong, stable performance and other advantages;

Q:What is the monitor for the video recorder?: Four division is one of the most commonly used equipment, its performance and price ratio is also better, the image quality and continuity can meet most of the requirements.

Q:What is the number of lines that a surveillance camera needs to use?: 2, video cable (transmission video signal, syv75-3, syv75-5, syv-75-7 these three are the most commonly used)

Q:What is the minimum illuminance indicator of the surveillance camera?: Therefore, the use of different F value of the lens, the camera's minimum illumination value of the determination will have a decisive impact. Second, the light source color temperature. The color temperature is an indicator of the light wavelength content in the light source. A 3200K light source is mostly between 600 nm and 900 nm, and a 9300K light source is between 300 and 500 nm, so the different color temperatures will change completely Test Results. On a typical CCD sensor, a light source with a wavelength of 600 nanometers will produce 10 times more electrons than a wavelength of 900 nanometers. This is why the color temperature is particularly marked for the meaning of the minimum illumination measurement results.

Q:Monitor the difference between the camera 720p and 1200 lines: 720P is 1280 X 720 pixels short, usually also known as 100W like. Is a parameter of the clarity of the digital camera system.
