Board CamerasThis security camera has fixed lens mounted on circuit board. It is also known as spy cameras due to its pinhole lens that is concealed for surveillance purposes. This camera is recommended for residential use because its flexibility is unlimited as well as its focal length. If you want to invest in a security camera system, you should choose the one that features high quality digital video recorder. This recorder transfers the video feed from the analog camera into digital format. You can choose from two types of digital recorders as follows:PC Based SystemsA software and special board is installed on the computer so that the camera inputs will be stored on the hard drive. Using your personal computer will not do the job. Even security specialists cannot guarantee its efficiency because computer based DVR is vulnerable to software crashes, system instability, virus related problems and software crashes. Stand Alone Security Camera SystemsThe control functions and appearance of this security camera system is similar with the standard VCR recorders. System crashes can be prevented because the video processing is done by the hardware and the video in digital format is also stored in the hardware. Linux is the usual operating system that is impossible to corrupt or overwrite.

I a little more work on making it easy to hide the wires behind the unit once installed would be nice. The small screw on the bottom to secure the device to the plate can be a real pain. Lost it and had to improvise with a small sheet metal screw.

10D, in some implementations, the bypass unit 1012 may also function as a voltage meter to determine whether the transformer 1010 can provide a supply voltage sufficient to drive the doorbell camera 106 which normally consumes more power than a conventional doorbell. The bypass unit 1012 includes a voltage monitoring unit 1012A, an LED indicator 1012B, and bypass circuit 1012C. The supply monitoring signal is generated by the voltage monitoring unit 1012A of the bypass unit 1012, and the LED indicator 1012B is located in the bypass unit 1012. The LED indicator 1012B sends a visual message to the user to indicate whether the input AC voltage is low with respect to the supply threshold. Likewise, in some implementations, the remote chime 1006 may be configured to ring differently based on the supply monitoring signal, thereby indicating whether the input AC voltage is sufficient to drive the doorbell camera 106.
