PeteMilligan 0 Posted April 14, 2019 All. New here. I'm intending to install a Hikvision DS-2AE5225TI-A on the corner of a building. This is a second home by the seaside. I'll need to have the camera monitor a 270 degree field and record the results on a DVR. Powered by AC 24V & has PTZ via RS-485; 2 MP IR Turbo 5-Inch Speed Dome, 1920 × 1080 resolution, 3D intelligent positioning, Switchable TVI/AHD/CVI/CVBS video outputs. What would be the least costly and smallest form factor DVR for this application? It's going to be unmanned. Hope you can help. Pete Share this post Link to post Share on other sites
