  1. My elderly DVR suddenly rebooted by itself yesterday, upon (automatic) rebooting it does the usual system checks and passes them. The background video display is distorted (as if it's running at an incorrect sync rate), but the overlay graphics are fine. It then pops up "sys err 01-014" a few times before rebooting (and then doing the same again). Can anyone shed light on this error code?

    HDD format on old AVTECH DVR?

    Replying to my own question, NTFS is fine. Turns out the problem was actually a low +12v voltage rail to the HDD itself, hence the drive problems, not a problem with the drive after all.
  3. Up until recently the DVR's been fine, but it has recently been getting HDD errors with subsequent reboots. Have tried replacing the hard drive with an old but known good drive and experiencing "drive error" during initialising. Do these DVRs require the HD to be formatted in FAT32? I can't remember if the replacement is FAT32 or NTFS. Note that the DVR doesn't appear to have any formatting capabilities.

    Samsung PTZ & Pelco query

    Yes, it is. Obviously this shouldn't take much work to figure out using a multimeter, but the Samsung camera 6-pin connector looks to me like one of those hard to find connectors, tailor made for use with their own controller range.

    Samsung PTZ & Pelco query

    Thanks Sean, is full documentation supplied with it? Reading a few more posts here, I've seen mention that Pelco-D can control basic Samsung camera PTZ functions, can anyone confirm this? I could of course experiment, but the actual pin-outs are unknown to me for both the camera and the DVR which doesn't help matters

    Samsung PTZ & Pelco query

    Thanks Tom, the problem is the difference in protocol, unless I've misunderstood your meaning? Access to the connections themselves is no problem, although the pin-out on the main 6-pin connector isn't obvious (to me at least). Come to think of it I'm not even sure of the RS485 pin-out of the ACV787 either @ ljarrald - you was bidding for that same camera? I was surprised to win the auction, as I'm usually outbid in the past few seconds, so now I know who to blame in the future

    Samsung PTZ & Pelco query

    Thanks Sean, I assume the DIP switches are to select various protocols? Anyone bought from that firm before? I'm always wary of buying anything outside the UK and especially from China... As for using the camera with a pan/tilt head, that would be ideal, wish I could find one going cheap
  8. I've just bought a used Samsung SDZ330, a fixed camera offering just optical zoom/focus. I was assuming I'd be able to use this with my AVTech AVC787 DVR, but now I'm pretty sure it's only controllable using Samsung's protocol (the AVTech model only supports Pelco-D and their own protocol). I'll appreciate confirmation of this, or any suggestions on work arounds. For PTZ, the SDZ330 uses a 6-pin connector, 3 of which are used, but which pin is which isn't apparent in the manual, which would make any experimentation even more puzzling. As an alternative, the zoom/focus can be controlled using an external voltage, would this be a better route for interfacing to the AVC787 and what would be required?

    ID camera and wireless system?

    Correct me if I'm wrong, but I believe OFCOM have only made parts of that spectrum available to other parties, it's still in use by the military, law enforcement and amateur radio operators. Not sure about point-to-point links as used by broadcasters, although I recollect a general migration to higher frequencies being made a few years back.

    ID camera and wireless system?

    Yes, I'm familiar with microwave feeds, as a radio amateur I transmit/receive video on 1.3 and 2.4GHz (analogue only at the moment) and have experience with digital (and indeed digital encryption systems) as used on satellite. Flat plate beamwidths aren't actually that narrow compared to a dish, but obviously receiving it (and analysing it) would probably be a waste of time. I would add though that sometimes encryption isn't always enabled in feeds which you'd think would be secure...

    ID camera and wireless system?

    Thanks. It's annoying that there's no identifying lettering on it anywhere. Elsewhere locally there are fixed ANPR cameras with the same plate antennae. I'm assuming this is all linked to a police CCTV monitoring room, so would be via a secure system.
  12. Recently installed locally to me by the local council (located Canvey Island, UK). There are no markings anywhere to be seen. http://img97.imageshack.us/i/charfleetscctv.jpg/ I assume the flat plate antenna is operating on around 3.4 or 5.8GHz, presumably a digital and encrypted system. And yes, it should be rotated clockwise, I've already done that, but imageshack seems to ignore the flag for some reason.

    IR bandpass filters

    Cheapest method is to rummage through your old photos andfind an old, blank, exposed negative, it works very well.

    Android remote viewing for HTC Desire?

    I'm glad to report I've found an application at last: http://hit-mob.com/forums/viewtopic.php?f=7&t=18 It works on many camera/DVR models, the AVTech AV7xx range being supported for image only (so no control available, although you can make a preset for viewing camera individually if you wish). The application is available in a free or paid version.

    Android remote viewing for HTC Desire?

    Hi, thanks, I did try it, but it just kept trying to connect and not succeeding. It's a dynamic IP address, so I use an HTTP redirector, I assume your application allows URLs and is not just expecting an IP address? Note that pressing "back" to stop the attempts wouldn't work either, it just kept trying. I have emailed AVTech about such an application, am awaiting a reply.
