We use the P5532-E but yes, they are D1. I am not sure what the reasoning for going with the lower resolution was. I've only been there 6 months. There was a senior network engineer that was there for 12 years, who made the decisions, but he left in April. I started in February, and was just doing maintenance and troubleshooting on the network. Being that the new senior network engineer started in May and has little to no knowledge of cameras, I am being looked at as the subject matter expert. Thank you for all the info and opening my eyes to some things. It definitely has been helpful.
Another question for you: We are currently using Cisco VSOM for managing and viewing our cameras. We are moving to Genetec probably with in the next 6 months to a year. Any other suggestions? I haven't really looked at any other systems. I Recording is not a huge priority. We do work with local and state police sometimes, but do not record video on a regular basis. Genetec was suggested by the AXIS sales rep that comes by. I am not sure how many other systems they looked at. Checking out the forums and talking to you, I am realizing I really don't know a whole lot about the camera side of the world.
