I purchased HFW5231E-Z12E and PFA121 from Andy/Empiretec about a year ago, does anyone know if there is an extension mount for HFW5231E-Z12E, I have the camera setup to monitor back of the house and i want to extend or move the camera away few inches from the wall for better coverage. According to Dahua accessory guide PFB121W fits PFA121 but not sure HFW5231E will fit PFB121W, does anyone here has a suggestion or recommendation?
