The PTZ-TOOL programming module makes programming PTZ cameras a cinch. Security Camera King offers this for sale for customers because there are many people that have more than 1 PTZ (Pan-Tilt-Zoom) camera in their system. In fact, this tool is only required if you use more than 1 PTZ camera in your system, but it can be used to control a standalone PTZ camera as well.
When designing your own digital video security camera system, whether it is for residential or commercial use, it is important to make the right choice for the stand alone DVR for security camera. A stand alone DVR or Digital Video Recorder is basically the "brain" of the system that coordinates the functions of the component parts and provides for storage of the digital video files.
