Quads are more expensive than switchers. It does this by splitting your screen into 4 sections. Similar to switchers, you may manually select a particular camera and pull it up to a full screen view. However, only live images may be brought up to full screen view. Although some quad manufacturers have included digital technology that can bring a prerecorded camera into full screen view, we've found that the image is highly pixalized and does not meet our standards.
Multiplexers are the most expensive of the three.
Unlike quads, multiplexers allow your VCR to record all cameras simultaneously, and in full screen view. To learn more, please visit our Switchers, Quads, and Multiplexers page . They may have alarm hook-ups that will automatically trigger the recording process when an alarm has been tripped. This feature is commonly used with motion detectors. Either Standard or Time Lapse VCRs may be used with any of our cameras and systems.
