We have a large premises to cover and recently replaced our aging CCTV system with an IP based system. We went with a hikvision ds-7732ni-e4 NVR box and the cameras are a mix of PTZ and indoor / outdoor units. For reference, the outdoor models are hikvision DS-2CD2612F-I. On the outside poles we also have Luminite GX250 PIR detectors. The installer replaced the existing coax cabling with outdoor CAT-5 and everything seemed to be working properly. We then got in touch with the company that does the monitoring for our premises and this is when things went haywire. The monitoring company requested a camera / PIR numbering chart. I was able to draw up the camera layout and asked the installer for the PIR layout. I was told the PIR's are cabled directly to the camera alarm inputs instead of the alarm inputs on the back of the NVR. According to our monitoring company this is not the "right" way to do it and the PIR should be wired directly to the back of the NVR. I asked the installer if they could do this and they said it would require another cable run to all the outside poles and there would be significant cost involved. I'm not sure what to do at this point and would love to hear your suggestions. Thanks.
