The usage of camera jvc gr-dv800u charger is very simple, usually when properly installed lens, connected signal cable, switch on the power can work. But in actual use, if not properly installed the camera and adjust the camera and lens state, may reach intended use effect. The following is briefly introduced. The correct way of using the camera

1. Install lens:

The camera jvc gr-d750u charger lens must be allocated to just can use, generally should according to the actual situation of using the site to matching appropriate lens, such as fixed-focus camera, or zoom lens, manual aperture lenses or automatic aperture lenses, standard lens or wide-angle lens or telephoto lenses, etc. Another should also pay attention to the interface with the camera lens, is C interface or CS type interface, C interface and CS type interface lens for 1 inch thread all 32 teeth, diameter of 1 inch, the difference is the distance from the CCD camera target different, C style installation seat the distance from datum to focus for 17.562 millimeter, CS type distance than the target surface one more special CCD pick laps of length, CS type from the focus distance to 12.5 mm. Don't look down upon this one by laps, without it, lens and cameras can't normal focus, blurred image. So in installation lens front, have a look at first cameras and lenses are not the same kind of interface way, if not, you need according to the specific circumstances increase or decrease meet circle. Some cameras don't meet circle, and use as adjust rings, adjust after with a screwdriver, loosen the screw adjusting ring ring, at this time, turning adjust the target surface will be relatively CCD installed base backward (former) movement, also plays the role of pick circle.

Installed in front of the camera jvc gr-d396us charger, first remove cameras and lenses protective cover, then will the lens camera lens screwed gently and make it in place. The interface For automatic aperture lenses, you should put the line connected to the camera lens, the automatic aperture interface for electric two variable lens or camera, as long as three variable rotating lens in place, then temporarily without calibration its equilibrium state (only in the focal gather completed before the need to adjust its equilibrium) last correction.

2. Adjust lens aperture and focus:

Close camera shutter and backlight compensation on electronic such switch, will the camcorder on the scene, adjust to monitor the aperture of the lens and focusing ring, make the monitors image best. If it was in light of change is big, best applications camera matching automatic aperture lenses and the camera electronic shutter switch (ELC) in OFF. If choose the manual aperture should be the camera jvc gr-d350u charger electronic shutter switch (ELC) placed ON using the site, and in most bright (environment), the largest light as possible will lens aperture ON a big and still make the image is the best (can't make the image too white and overload), lens namely adjustment over. Pack good shields and superior stents can. Due to larger, preview range aperture relatively small, to focus should as far as possible when the whole monitoring site for clarity. When the site illumination reduce, electronic shutter will automatically adjust to slow, with larger aperture, still can make the image satisfaction.

In the above adjustment process, if do not pay attention to in the light bright will open the aperture of the lens as far as possible big, but shut are small, then the camera jvc gr-d347u charger shutter will automatically adjustable electronic in low-speed, so it can still on the monitors form good image; But when the dark, because when the aperture of the lens are small, and electronic shutter has at its most slow (1/50s), at this time of imaging is likely to be out of dim.

3. After adjusting the focal length of focal length after also says, refers to the back focal length when installation standard lens (standard C/CS interface lens), can make the imaging can be adjusted in just scenery of CCD image sensor into the target surface, general camera for factory after the focal length of all did appropriate adjustments, so, in matching fixed-focus camera, applications, generally don't need to adjust the camera after focus.

In some applications, focusing ring when the camera may occur when adjusted to limit position still cannot make the image is clear, now must first confirmed the interface is correct. Camera If confirmed, they need to adjust the camera after the focal length. According to experience, in the vast majority of camera matching electrical zoom lens applications, often need to adjust the camera jvc gr-d33us charger after the focal length.

After the procedure is as follows: focal length adjustment

A. will correct installation to the camera lens.

B. will lens aperture the largest open (as possible purpose is to narrow the scope to accurately find depth imaging focus).

C. through the Zoom is adjusting (complex modulation Zoom In) will push to dishes (Tele lenses, filmed) state of an object outside 10m close-up, again through adjustment Focus (something) will close-up image adjustable clear.

D. on the contrary with the Zoom is adjusting step (complex modulation Zoom Out) will pull back to the wide-angle lens, when Wide) state (containing all the close-up pictures into objects panoramic images, but at the moment can no longer be focusing adjustment (note: if the image blurring also unable to adjust focus), but the next step after adjusting the focal. jvc gr-d31us charger

E. the camera front-end for fixed focal adjustment ring after the hex screws unscrew and turn to the focal adjustment ring (after the focal adjustment ring after the no camera is directly rotate lens and drive with its built-in JiaoHuan), until after the clearest picture so far, then temporarily tighten hex screws.

F. to push lens to shoot and see just a distant view state whether a close-up of objects, such as not clear still clear to repeat the first a, b and c steps.

G. in dishes state, if close-up objects have clear, tighten hex screws, will adjust to the appropriate position aperture.

So far, cameras and lenses is commissioning finished. jvc gr-d30u charger
