I am looking for a vehicle sensor that will trigger an alarm on a Hikvision system. Currently, we get several false alarms a day and it makes it hard to search for the event of vehicles entering a gate. We have thought about using just a regular PIR sensor, but those seem to take a few seconds to be activated and would not work well for a fast moving vehicle. We are looking for something that is specifically designed to sense a moving vehicle.

No, the gate is in a fixed position most of the day and is manually closed at night. I am using an NVR. The camera has an alarm input in it.

Currently, we are using a Hikvision 7700 NVR with support for 32-channels. On a few of our outdoor cameras, we are getting so many false alarms and events that it is making that feature useless. We have heard about putting in some type of IR alarm that can detect motion better than the NVR can. Does anyone know a good place to buy these products? Also, is there anyway the alarm input/output can be run over LAN instead of being plugged directly into the back of the NVR?

The PIR would too far from the NVR to plug directly into the back of the NVR, although we do have an Ethernet switch it could be plugged into. Are there any devices that can convert that circuit info to Ethernet and then back again to go into the back of the box?
