Advice needed on DVR/Camera setup for small office

[Ned <nedhart@xxxxxxxxxxx>]

My brother's assistant of 18 years just resigned from his small
medical practice and it will take a while to replace her. In the
meantime he wants to be able to monitor the patient waiting area from
any of his 4 exam rooms, all of which have networked computers. I was
thinking of an IP/network video camera but then I remembered that he
also has a camera outside of his office which is used to see who is
ringing the doorbell, this camera is old and is connected to an old BW
CRT. I told him it might be a good idea to install some new cameras
around the office, not more than 4, and to record to a DVR. I have
been googling and I read that GE makes a good product. I am
considering the SDVR-4PII-80 StoreSafe Pro II (link below). As for the
cameras, I was looking at the bullet cameras because the office is
very small and a larger camera might intimidate patients. I would also
appreciate recommendations for an online vendor. I think a $2,500
budget for parts would be in his range.
thanks!
