Just seen an interesting white paper on studies that have shown you can be identified by your interaction with WiFi signals.
http://arxiv.org/pdf/1608.03430v1.pdf
If you don't care for reading a white paper the overview is this maybe useful for smart homes of the future and has potential for domestic intruder detection.
Will need a fair bit of work before it could be used but the concept could see the end of the movement sensors and domestic security as we know it.
It is advisable to use a static IP that is outside of the pool over DHCP.
This sounds like a server side issue that happens on occasion.
Linked into your own DDNS service or Static IP with Update IP off is best solution IMO.
There is setup required on the panel and with the web interface.
If you follow the manual word for word and you understand the terms you shouldn't go wrong.
I would switch off the COMWiFi local network while in the interface configuring it.
If you do get the ARP issues you mention above and are not sure on clearing them, you can simply reboot everything wait for connection to come back up and then continue.
As petrolhead says and also the listing -> "This cable functions as a signal transmitter, but NOT a signal converter."
You need to convert to a composite signal to use the existing modulator.
They probably doesn't get used, some are for playback purposes only anyway.
Granny Goggins is most likely listening to The Archers?
But yes I have been in that situation explaining how to switch HDMI channels for the sake of the cost of a separate monitor.
If you are converting HDMI to a composite signal then the analogue modulator should work fine.
Is this the Luxrite LHD DVR or the SPro Six?
Also AHD CVI and TVI are analogue but they are not composite BTW.
FYI
A number of vulnerabilities have been discovered in the Qualcomm chipsets used in many Android handsets from many of the leading manufacturers. Exploitation of these vulnerabilities could allow an unauthorised user to take full control of an Android device but in order to do so an authorised user would first need to install a malicious app.

I'd rather have a 20 year old scantronic than some modern 1 way wireless tat. All about the risk?
Seems like a simple swap like for like, it's the same reason obsolete keypads sell well on ebay.
Very easy to swap something like for like, although I have known "engineers" to get this wrong.
It would appear the battery has gone faulty and used your issue.
It's possible that the unit is faulty, would be best to have it inspected to make sure the panel has kept it's programming and the panel isn't damaged.
A new battery maybe all it needs but without proper testing you will not know if it's likely to do it again.
