Review on 4MP HD PTZ Outdoor POE IP Camera OEM DS-2DE2A404IW-DE3, Pan/Tilt/2.8Mm~12Mm 4X Optical Zoom, Built-In Mic,Night Vision 20M,SD Card Slot(Up To 256G), Audio Input Output,IP66 And IK10 by Cesar Rios

I bought this to replace a Hik 2.4mm turret and I am more than happy with the results. With this being said, this is definitely a value-model and will not have a lot of the bells and whistles for tracking objects/motion. If you're simply wanting to have a visible area multiplier, as I did, this well-exceeds any other device in size and features. Optical zoom/focus is my favorite feature. Night vision is decent, especially if you have other IR sources. Speed is adequate. Software is no different than other Hikvision products. I am using BlueIris and am pleased with the level of compatibility and relative ease of getting it connected. Physical installation was a little difficult as the protective shroud is made so that if you use anything other than the supplied screws (my application called for self-tapping sheet metal screws) it will hit on the screw heads and not secure properly.
