I have bought this DS-2DE4425IW DE(T5) and dissapointedly find there's no smart tracking. It's very confusing the customers by having some variants of this camera (DE, AE, T5, S5, S6).
This camera has amazing capabilities but became useless without smart/auto tracking.
I really hoping that hikvision make new firmware which have the smart tracking feature into it. I'm aware that hikvision have this smart feature on others line up for more expensive price tag.
But as average costumer (who want to built hikvision security system for my home), i could bought other cheaper cctv with decent capabilities (including smart tracking), but honestly, i dissapointed by choosing this camera with amazing capabilities but become useless by not having smart tracking.
