A CAT 5 cable connects the security
camera to an internet protocol. The camera has two types – decentralized IP security camera and centralized IP security camera. A decentralized IP security camera has a built in recording function. A centralized IP security camera needs a NVR network video recorder program. The NVR program records images that are stored in a digital storage device. The digital storage device may be a SD
memory card or a USB flash drive. A disk drive may also be a digital storage device. Professional grade Security CameraThe professional grade security camera has a detachable lens. The camera allows people to use it for different applications. For example, a standard security camera can cover a distance of 35 40 feet. Distances that are beyond 40 feet can be covered by the professional grade security camera.

Alternatively, in some implementations, at least part of the method 1050 may be implemented at the bypass unit 1012. Independently of whether the doorbell camera 106 is
electrically coupled to the remote chime 1006 in place of a conventional doorbell, a supply monitoring voltage may be generated 1056 in the bypass unit 1012 based on the input AC voltage to indicate whether the input AC voltage is greater than a supply threshold. In accordance with the supply monitoring signal, a
message may be presented 1058 by the bypass unit 1012 to a user of the doorbell camera 106 to indicate whether the input AC voltage is low with respect to the supply threshold. Optionally, the message may include a visual message displayed on the bypass unit 1012 by an LED indicator 1012B according to one of a set of predetermined visual patterns. In some implementations, the message presented to the user may include a ring of the remote chime 1006. By these means, voltage compatibility of the doorbell camera 106 may be determined and known to the user of the doorbell camera 106 before the doorbell camera 106 is installed, thereby avoiding installation of the doorbell camera 106 when it is not even compatible with the supply voltage provided by the transformer 1010. More details on the method 1500 implemented by the bypass unit 1012 are explained above with reference to FIG. 10D. FIGS. 11A and 11B include a top view 1100 and a cross sectional view 1140 of a doorbell camera 106 in accordance with some implementations, respectively, and FIGS. 11C 11E are three exploded views of a doorbell camera 106 in accordance with some implementations.
