For your remaining cameras, see about getting the firmware upgraded to the latest available version. Pelco Sarix Cameras use NAND memory, which is better (in theory) but is also newer to developers, and found to be more susceptible to corruption that can cause the camera firmware to fail (but not really a hardware problem). To prevent this, Pelco implemented more robust software-based CRC (error checking) in versions above v1.8.2.
