updating entire system from analog

[gunthonungo2 0]

using a very old setup of analog cameras and am about to update everything.  Should I reuse the coax and go for hdtvi and cvi cameras or just start over and go IP everywhere?  Also would a hybrid recorder such as the Hikvision DS7216-HUHI-K2 be a good idea or what do you all recommend in terms of recorders?  What cameras would you all recommend?  This is for a hotel so it is decently lit up outside at night don't want pictures getting washed out and want to go 2MP or better.

 

Thanks
