Hard Drive Type

[Steevo25 0]

Hi All,

 

I am a complete newbie when it comes to CCTV, but I have installed one in my home and it all seems to be working very well. It definitely meets the criteria that I had wanted.

 

There is, however, one thing that I want to do and that is increase the hard drive space of my DVR. I have been told by the manufacturer that the DVR ( AVTECH AVC760 ) can take a 750GB drive. They didn't tell me what specification the drive must be though and it takes a while to get any reply by email ( they are in Taiwain and I am in the UK ).

 

Does any one know what the likely spec of the hard drive would be ( I know its IDE, but what RPM etc etc ).

 

Many Thanks.

 

Steve.

Hi Steve,

I assume you're talking about this Seagate HDD (I don't think there is another 750GB EIDE that is commonly available):

 

Specifications 750 GB

Model Number ST3750640A-RK

Interface Ultra ATA/100

PHYSICAL

Cache 16 MBytes

Capacity 750 GB

PERFORMANCE

Spindle Speed 7200 rpm

 

Unfortunately Seagate don't list current draw @ 5/12V on their website as those figures would be my only concern with using this HDD in the AVC760.

 

I highly doubt Avtech will have tested AVC760 with a 750GB hdd in particular, and if they did then it would appear in the table at the back of the manual, however, in "theory" it should work.

 

Reason: AVC760 supports LBA48 and is based on the same basic hardware and the same basic firmware that AVC787 / AVC787D use and I know for a fact that the Seagate 750GB's work on AVC787D because we loaded one up for a customer along with a fully loaded (3x750) hdd array (total 3TB).

 

As I said my only concern would be the power supply but with Avtechs most recent PSU's (i.e. all of their MPG4 DVRs) all that happens when you overload a rail is the unit shuts down.

 

Also do you realise that if you do put the Seagate 750GB into AVC760 that you will probably be the first person in the world that has done so... AVC760 is the entry level / economy DVR and unless UK prices are much different to AU prices you should be paying more for the HDD than the DVR

Mant thanks for your reply. Overall, I have been extremely impressed with the AVC760, and yes the HD is costing more than the DVR ( roughly double ).

 

It is only used for home surveilance, and I was very apprehensive when I first bought it because it was near the bottom in terms of price.

 

A friend of mine has a DVR that was well over double the price exclusive of disks and comparing his and mine, I really cannot see any difference. This has all the same features as his one ( except that on his one an external disk array can be added and it has a DVD writer ). In terms of picture quality and features there is absolutely no difference.

 

I am trying to get 15 days stored on the disk as if I go on holiday, it is never for more than 2 weeks. As it stands, I get about 11 days in best quality and 25IPS Frame. It currently has a 500GB in it. If I put a 750GB then that gives me about 15 days using the best quality I can get with the unit. Thats perfect for what I require.

 

I did email AVTech asking them if there was any way a 2nd HD could be added or if a 750GB would work. The said that it would not be possible to add a 2nd drive but confirmed that a 750GB drive would work in the unit.
