Sensors for xprotect or similar for trip and motion?

[pounce 0]

I have an alley that has some Hikvision cameras on it. At night I get way too many events from flying bugs and actually rain at times. I'm looking for options like trip beams or some PIR sensors in the locations where people would have to pass into the space where cameras are pointed. I'm hoping that I can detect motion near where the motion is happening vs in camera detection from two stories up.

 

Does anyone have some suggestions? I looked for IP based PIR sensors etc, but didn't find a lot. There must be a better way that i'm not seeing.

 

I have xProtect running at the moment.

This will help you understand how to make this work

With Hikvision cameras and current firmware, you can set it to trigger on line traversal. Meaning an object would have to traverse a line in a given direction for it to trigger. This was introduced in 5.1.6 and dumbed down a bit in 5.2.0 but may help in what you are doing with spending a lot of time and money. You then set this up in Milestone XProtect to use the hardware event. PIR is not perfect either as birds, squirrels, dogs may trigger false alarms.

Thanks for the replies guys.

 

I know I don't have that option on my Hikvision cameras. I'll have to check the firmware version. I have US cameras from an official dealer so I guess I can get upgrades somewhere if I'm simply behind.

 

The issue I have at night is that the IR attracts so many bugs that the cameras are recording way too much. I'm not sure if the traversal approach would work for bugs or not. They fly in circles. I'm sure they would fly right over the line.

 

I'd really like to use some sensor near the ground to start the recordings. I see in the other link that sensors like door and window can be used, but how to translate open/closed circuit to IP events?

First you have to have a camera with alarm inputs, do yours? If they are Hikvision, you'll need a model with the letter S at the end, like ds-2cd2732f-iS. It will have a pigtail with lots of wires or on the newer ones have a green connection block. You connect two wires from the sensor to this, then connect the other two wires typically to a 12V power supply.

 

If it's a Hikvision, under Advanced Configuration, Events, Alarm Input, select NO (normally open) or NC (normally) closed, and select "notify surveillance center". Then in Milestone, add the hardware event as you normally do and trigger recording of that camera on that hardware events.

 

If the IR is causing problems with bugs, turn IR off and use either external illuminators not near the cameras or light up the area at night with traditional white light.

I only have one camera that has the i/o and its not an outside camera. Its one of the bricks. I thought the S was sound, but maybe with sound you get i/o also.

 

I know I can turn off IR. Its sort of a shell game. I like the on camera IR for the most part and it works pretty well. I don't want to buy more IR projectors if I don't have to. Yes, I''m considering it as an option. I just don't want to have to wire up more power and hang more stuff. The clutter of having cameras and IR lights and floods is not attractive. I cant go with floods for the area for a few reasons. It needs to stay more or less dark at night.

 

Doesn't anyone sell a relay that can simply send alarms or events based on tripping a circuit... without having a camera? How does one normally integrate an alarm system with a camera system so that the alarms start recording?

 

I'm sort of investing in finding a solution for this because I think I can use the solution in more than one place or for other needs.

 

A simple use case is that I want to use an event or alarm to start recording on more than one camera. The event or alarm goes to xprotect. Xprotect manages the event or alarm and records from the cameras.

With Avigilon we can use this unit from Moxa to add trigger I/O to the system if we need more than what the cameras can provide. Another option is to get a cheap encoder which has trigger I/O. Most of the 4 channel encoders have 4 inputs / 4 outputs

I would check Milestones supported list and see what network I/O devices they work with.

In theory, you could get a small computer, say an Arduino YUN, BeagleBoard or Raspberry Pi, have it sense motion using a PIR motion detector attached to the boards inputs. Then write a program or script that takes that input and sends an URL command to the software to trigger recording. It would probably be cheaper than an outdoor PIR motion detector as they tend to run about $100ish to start and I can get a Rapberry Pi for $30 and get PIR motion detector for $10 and find a way to seal it all watertight. Not only less expensive, but may afford you a way to connect a camera without alarm I/O to a sensor. Also you can attach all sorts of sensors to it, for example, you can have multiple PIR sensors, trip wire sensors, pad sensors, laser sensors on the same Raspberry and send commands to cameras or NVR software based on what's triggered.. I can't say for sure on Milestone, but people do this now with BlueIris.

 

Also, you can attach a PIR motion detector to your indoor camera, mount the motion detector outdoors, set it up as a hardware event in Milestone, then use that as a trigger to record a different cameras as the alarm I/O does not have to be in the same camera as the one recording.

thewireguys, thanks for the guidance. It pushed me in a good direction. I might play with and axis unit:

buellwinkle,

 

I was also thinking along those same lines. I have a drawer full of arduino. Was looking at BLE chips. They can run a year on a coin battery. If I knew how to send an http event/alarm to xprotect I'd go down this path. My google-fu wasn't finding much. Next step was to get the Milestone SDK and dig through it. Another thought is to leverage insteon devices.

 

Thank you both.

buellwinkle, Do you know if the Arduino works with a regular PRI, like an Optex LX-402?

Hi, what scene should I choose in milestone to get the crossline working from Hikvision?

What should Hikvision notify? Notify Surveillance Center or Alarm output?
