Q: Camera gun 4MM, 6MM refers to what?: Camera gun parameters in the 4MM, 6MM, etc. refers to the camera is configured lens focal length.

Q: 3 megapixel surveillance cameras store much day: 3600 seconds (per hour) * 24 hours (per day) * Rate (128kbps-8Mbps) / 8 (conversion of bytes and bits) / 1024 (converted to M) / 1024 (converted to G) ≈42G (bit rate is 4Mbps)

Q: Monitor the type and purpose of the equipment: 3. Color dome camera for indoor, ceiling place easy to install.

Q: How to connect a hard disk video recorder to a computer: (1) If it is in a local area network, as long as the hard disk video recorder inside the IP and computer IP in a network section on it. If you want to directly use the network cable can also, the method is the same, the first IP in a network segment, in a cross with the network cable can be connected through IE.

Q: Monitor the camera what is the zoom: The lens is equivalent to the human eye lens, if there is no lens, the human eye can not see any objects; if there is no lens, then the camera output image is a vast expanse of white, no clear image output, which with our home camera and camera principle Is consistent. When the human eye can not stretch the lens to the normal position, that is, people often say myopia, the front of the scene becomes blurred; camera and lens with a similar phenomenon, when the image becomes unclear , You can adjust the camera's back focus, change the CCD chip and the lens reference plane distance (equivalent to adjust the position of the human eye lens), you can blur the image becomes clear. Thus, the role of the lens in the closed-circuit monitoring system is very important. Engineering designers and construction workers should often deal with the lens: the designer according to object distance, imaging size calculation lens focal length, the construction staff often on-site commissioning, part of the lens is to adjust to the best condition.

Q: Will the surveillance camera brand which?: High-end cameras - the series of cameras are Japan, South Korea and Europe and the United States famous brands, such as SONY, Panasonic, SAMSUNG, SANYO, Philips, PELCO and Tyco-AD and so on. Among them SONY SSC-DC338P (480TVL, 0.8Lux), Panasonic WV-CP470 (480TVL, 0.8Lux) two color cameras and SONY black and white camera in all aspects of performance are more excellent

Q: Monitor the camera image virtual how the matter: 2, line aging. Resulting in poor line shielding, near the interference source on the line caused by image jitter is not clear. Replace the line can be resolved.

Q: An accurate calculation formula for monitoring the focal length and actual distance of the lens: The size of the imaging scene and the size of the imaging object are contradictory, for example, with the same camera to monitor the same parking lot, the choice of short focal length lens can be the entire parking lot to monitor and see the entrance Outside the vehicle out, but can not see the car's license number (the car in the monitor screen only occupies a small area)

Q: Monitor the camera feel infrared: There are two kinds of camera lens: one is a CCD is a sense of the infrared are infrared (day and night type) lens and color lens sense of infrared lens

Q: Monitor the camera lens focal length is what the situation according to the scope of the big focal point what the situation according to the clear: Dome cameras generally have 2.5mm, 3.6mm, 6.0mm.
