Scantronic I-On 40 - Using Outputs To Activate Ip Cameras

[Hoppo]

Hi,

 

I have a Scantronic I-On 40 and want to know if I can make use of the Outputs from it to turn on my two IP security cameras.

 

The IP securtity cameras are connected to a POE (power over ethernet switch), so I just need to turn power on to the POE switch when the alarm is set.

 

The alarm has four outputs:

 

O/P 1 - 2:

Voltage free, single pole relay contacts rated 24VDC @ 1A.

O/P 3 - 4:

Open collector transistor, +12VDC when inactive, 0V when active. 500mA max. 

 

 

Is the best way to wire up a relay to one of the outputs and use the relay to turn on power to the switch? Can you point me to a suitable relay?

 

Many thanks

Assume we know what POE means. You could use the low volt output in the panel to drive a bigger relay but why don't you want the cameras on 24/7?

Do your camera's have alarm inputs?

OP, if you really want to do it that way, the clue is in the name for Op's 1 and 2....

 

Relay contacts with NC C and NO available. Obviously don't do it on the mains.

 

How come you don't want the cameras on all the time?

Thanks for all the replies.

I don't want the cameras on all the time as I am emailed when they detect motion. If they are on when I am home then my inbox will rapidly fill up. I'd rather just be emailed when I am not home which is why I'd like them to be activated when I turn on the alarm.

The cameras don't have an alarm input but I'll connect them to a dedicated network video recorder which has POE outputs to power the cameras.

So I just need the Ion-40 output to turn on the mains socket (or supply power) to the network video recorder.

I have looked on the Maplin website for power relays and am a bit confused by all the choice there - can anyone point me to a suitable one?

Thanks.

This would do the trick. Just need a plastic box to wire into.

Ion 40 already has a decent dry relay contact on board though.

 

OP if you really want to do this, just cut ONE of the two DC wires feeding your hub (I'm assuming it runs off a plug top transformer?)

and wire into COMMON and NO of either OP 1 or OP 2 on the ion.

 

Then set OP 1 or 2 type to System Set as appropriate. If you're using the 40s web-browser that's nice and easy.

Many thanks.

I'll go for the external relay as I think the amperage required would overload the Ion's relay - it will need to power the NVR (containing a hard disk) and up to 4 ip cameras connected using POE.

I do use the Ion's web browser. Thanks for the tip on doing the set-up that way, Datadiffusion.

Sorry didn't realise it was the NVR too yes, of course you'll need the external.

 

I just imagined the tiny 4 port PoE with a plug in transformer. My mistake.

 

Hope the NVR HD is OK with suddenly having the power pulled rather than shut down?

[Hoppo]

Or maybe the OP from the Ion could handle the power requirement. The NVR, hard disk and 4 IP cameras would draw just under 50 watts (and I'd probably only connect 2 or 3 cameras anyhow). Do you think that's possible?
