windows Arp

I am not that familiar with ARP, but at work we were having a network problem and were trying to find the MAC address of a device. It is not a windows computer, it a device that runs a camera.
I tried

arp -a 192.168.0.10

192.168.0.10 is the address of the device and I got this

No ARP entries found

If I run arp -a on my pc, I have a lot of entries.
So is there some trick to running arp -a on a remote device to see the mac address of the remote device?

Try Wireshark and ping that IP. In the reply package headers you should see the MAC.
Or, if your router has that ability, you should see in the status page the MAC for that IP.

Is 192.168.0.10 the IP address of the camera/device?
You could download/run ZenMap (NMap GUI) and run a ping scan on 192.168.0.* that would return all IP's and MAC addresses

first PING 192.168.0.10
then before the arp-cache times out
ARP -a
If the PC and the device is in the same IP-range then the MAC found will be that of the device (otherwise it will be the MAC of next-hop-router , default gateway)

A router could have the MAC in arp-cache if you are dealing with more networks.
