Regardless of whether you need to make a list of number plates that must open the gate, see which faces the camera has recognized - or find recordings based on the voucher number in a supermarket, iVMS is your friend.
iVMS-4200 is a central part of Hikvision's software package. The software can be used to configure their cameras and intercom - but can also function as an entire monitoring center. The program is free - and there are no fees.
The program supports end-to-end encryption between the PC and the cameras.
