HD camcorders | How to improve the effect of the high-definition camera | HD camera features how to improve the HD camera use effects? For the use of surveillance cameras is actually very simple, but more and more monitoring projects, professional use, or lack of, If you do not understand the relevant knowledge, surveillance cameras may not achieve the desired effect'll tell you about today about how to better use of surveillance cameras, in fact, a good grasp of three o'clock just fine. First point: back focal length adjustment, the back focal length is also known as the back focal length, when installed on the standard lens (standard C / CS mount lens), enabling the imaging of the subject scene just into the target surface of the CCD image sensor on General HD camcorder at the factory, back focus, do the appropriate adjustments in applications connected with fixed focus lens, generally do not need to adjust the back focal surveillance cameras. The second point: adjust the lens aperture and focus, turn off the electronic shutter, and backlight compensation switch on the camera, HD camera at the scene you want to monitor, adjust the lens aperture and focus ring, so that the image on the monitor. If use of surveillance cameras, the best matching auto iris lens and camera electronic shutter switch (ELC) is placed in the OFF occasions in relatively large changes in illumination. If the choice of a manual iris should be placed on surveillance camera electronic shutter switch (ELC) ON, and the brightest spot in the application (ambient light), the lens aperture as possible to open a large and still-image for the best (not the image too pale overload), lens adjustment is completed. Installed shield and to Shanghao bracket can. Due to the larger aperture, depth of field range is relatively small, the focal length should be as far as possible to take care of the clarity of the entire monitoring site. When the scene illumination is lowered, the electronic shutter is automatically adjusted to slow, with a larger aperture, can still make the image satisfaction. The above adjustment process, if not pay attention to open a large lens aperture as possible in bright light, but shut small, monitoring the electronic shutter of the camera will automatically adjust at low speed, can still be formed on the monitor better image; However, when the light dimmed, the aperture of the lens is relatively small, and the electronic shutter has also been at the slowest (1/50s) imaging at this time may be a dark one. The third point: Install the lens, HD cameras must be fitted then the lens can be used to matching the right lens should generally be based on the actual situation of the application of the scene, such as fixed focus lens or zoom lens, manual iris lens or auto iris lens, standard lens or wide-angle lens or telephoto lens. Also note that the interface of the lens and camera, is a C-type interface or CS-type interface, the C-type interface and the CS-type interface lens thread 32 teeth are 1 inch, 1 inch in diameter, the difference is the distance of the lens from the CCD target surface different C-mount distance from the datum to the focus of 17.562 mm, more than CS-distance CCD target a dedicated up lap length CS style from the focus distance of 12.5 mm. Understand and grasp the above three points, use effects for high-definition video camera will be significantly improved, and also the good quality of the monitoring project. 700-line HD cameras RS-827EF Features: ★ 1/3 "SONY Exview HAD II the CCD ★ ultra-low power consumption through rigorous electromagnetic interference testing ★ ★ digital noise reduction ★ icon menu-60mA current ★ 100dB wide dynamic range only OSD control camera functions ★ standard 5-key control OSD 700-line high-definition camera technology parameters: Sensor: 1/3 "SONY SUPER HAD II CCD level resolution: 700TVL pixels: PAL: 753 (H) * 582 (V), NTSC: 768 (H) * 494 (V) Image Format: PAL / NTSC synchronization mode: 700 Internal Line waterproof camera correction 0.3 - 1.0 set the signal-to-noise ratio:> 50dB (AGC OFF) Electronic shutter speed: PAL: 1/50-1 / 100,000 sec; NTSC: 1/60-1/100, 000 automatic gain: OFF ~ 33dB Minimum illumination: 0.01Lux/F1.2 video output: 1.0Vpp 75 ohm BNC output high-definition camera power supply: 12V DC (± 10%) lens drive: Board lens, Fixed lens optional / DC drive function control: OSD PCB size: 261mm * 81mm * 177mm Operating Temperature: -10 ° C to 50 ° C to 700-line high-definition camera work environment: 10% to 90% of the company: Shenzhen South Electronics Co., Ltd.
