Just a note i had this installed outside and connected to a Dahua NVR and wanted a bigger zoom so bought a BOSCH and guess what the Dahua is better as the Bosch 2mp Ones, colours are not as good and the field of vision is much worse

So want to install it again but with the updated firmware

im also selling a few DAHUA 2MP PTZ IR 30 x DH-SD6AEA230FN-HNI cameras and wanted the new firmware was up to date
