Advice on CCTV Security Surveillance DVR
A friend of mine has a Surveillance system in his place of business.
It is a mechanical garage.
The DVR gave up and the people that installed it can not be reached.
It had 4 cameras connected to it and they seem to be working OK.
'The DVR is connected to his router.
He asked me if I can replace it.
I would like to get one that is better quality than the ones they sell at Costco or similar places.
Would anybody know of a source to get this type of DVR or advice on a brand or a model number.
It has to have the capacity to be viewed remotely form a android device
Thanks in advance.
