The front side is flat along the top and bottom edge but has curves similar to the company's Galaxy S series flagships at the left and right hand edge. No indication is given with regard to scale but, based on the size of the camera sensors in relation to the overall size of the doorbell, it wouldn't likely be much larger than a few inches wide. Background: Samsung has had at least some experience in the category of camera enabled doorbells and similar technologies thanks in part to former subsidiary Hanwha Techwin and its SmartCam lineup. However, it has been quite some time since any new products were launched under the Samsung branding. Finalization of the sale of Samsung Techwin to Hanwha Group was completed in 2015, with the newly merged company rebranding as Hanwha Techwin. The Korean tech giant's efforts in the space since that split have been almost entirely non existent.

Choosing the Right Security CamerasIf you are thinking of buying security camera, you should pay attention on the size of the CCD chips. Cameras using CMOS technology usually have poor light sensitivity and produces poor quality images. The larger the chip the better images it may produce but you should expect that it is more expensive. The picture resolution of the security camera image can be measured by the number of TV lines. The larger the number of lines, the better resolution and picture quality you can expect. If you will use the security camera in places with poor light conditions, then you should choose the B/W chip cameras that produce better light sensitivity and greater resolution.
