Thank you boogiman for your replay but do you mean make the resolution in full frame and decrease the bit rate ? What's the value of bit rate you recommended?

dear all i have project contain 52 ip camera and my problem with hikvision nvr 9664 is while adding the cams to nvr the first 45 cam added normal but at cam number 46 the nvr reject it and appear message " no enough network bandwidth" after that i decreased the resolution from full frame"35fps" into 20fps but the problem not solved note: the nvr bandwidth is 160 MB which if we calculate the currant bandwidth will be 45 cam*20fps = 90 MB so we still have enough bandwidth after decrease the resolution into 20fps but the problem not solved yet any help....any advice.. the delivery date of the project very close best regards
