AVTech CCTV Open Cover
You can find AVTech from their official website.
It is building using not expensive electric board and hardware, but it works. That’s why they can do such mass production. If you would like to upgrade the storage, you can just buy a larger size hard disk drive like 1TB to replace after the warranty expired.

Old time
It is very difficult to make a running CCTV many years ago, we need CCTV PCI card slot into PC motherboard and install their buggy software to run the CCTV. Now days they just run within these hardware, without fast processor, without CPU fan, or any fan, then can run up to 4 cameras and high capacity recorded storage.
Cost
I’ve been running this device for more than 4 years without any big problem other than camera hits by storm. It use low power supply, so I plug with my UPS can run up more than an hour. These whole set cost me around USD 750 few years ago. I can say that it is very worth.

Dear Sir,
I using AVTech 16channel DVR AV787M-HO, now i having the DATE problem, the DVR always changed DATE to year 2000, even thought correct back to current Date, after few day the DVR still back to year 2000, i suspect cause by battery,and checked found the battery was weld, please advise me how to solve this problem.
thank you,
Best Regards
There are no battery inside the DVR, I suggest you plugin your Avtech to UPS then can stay your DVR online 24 hours without problem.
I have the same DVR as pictured above and after a power failure it does not recognise the HDD. What is the operating system that this unit uses? I will replace the harddrive if necessary but need to know what format to use?
As for the time problem above, it is known for the unit to revert back to 2000 year after any power outage unless you are on a ups and it has enough running time till the power comes back.
There is a small 3V battery weld at the other side of motherboard.That replace a 3V battery can sole DATE losing problem without a UPS.
