I currently am using Speco 32NVR since it's IR controlled with Amcrest Cameras using ONVIF.. I once had all Speco cameras that my C4 dealer sold me, but the cameras were so bad at night I finally got so fed up with the cameras I ripped them all down and I started looking into different cameras on my own. I tried a number of them, but found Amcrest to have the best clarity at night especially in zero light. Its like night and day and a fraction of the cost compared to what I paid for Speco. I think ea speco camera was like $300+ for their flexible intensifier and the Amcrest varifocal was like $125. and the amcrest has so much better clarity at night. My dealer tried to offer some other cameras, but after I had already spend over $7500 for 25+ cameras then another $1500+ for the 32 NVR I was done with their suggestions. So I just ordered a bunch of different cam's and started evaluating until I found ones that had the best clarity in no light areas. Amcrest was the winner for my situation. but the amcrest NVR is not IR Controlled so I can't change views like I can with the SPECO from the C4 remote since the Speco NVR is IR controlled. Thats the only hang up with Amcrest NVR and my C4 setup. Anyone know of any other IR controlled NVR's that work with ONVIF cameras. Speco works, but I need to get a few more NVR's at my other locations and I don't feel like paying $1500+ on a 32 Speco NVR. Thanks. thought Id ask
