Theres nothing wrong with Hikvision. Its resller you should be after for not giving full disclosure on how camera operate.
I had this scenario 2 times. Both faced different issue
1st client used old lock which pulled strong current , relay upon opening sticked and didnt want to release basicly fried
2nd client added huge unlock time and forgot to mention ....
I believe both camera and nvr has to support acuseek to work. I might be wrong. I believe the Camera sends realtime metadata so acuseek NVR can store those metadata and serach it later for fast display.
What are you camera models?
