I have just obtained 2 new cameras which are 12vDC/24vAC auto switchable, when turned on using a 12vDC supply, it can take some 5 minutes for it to warm up and get a stable picture. I dont suppose this is normal, or is it?? there isnt a drop in voltage after turning on. I dont want to go and buy an AC supply to find things are the same. any ideas please

many thanks sean, I will bear that in mind if I need to use it permenantly

Does anyone know where I can get the Direct drive (DD) socket from (fitted on side of camera), or even an auto iris cable extention lead (if they exist). I can get the plug part easily. I have searched Radio shack, but maybe they are called something different in the states.

Found them on Ebay( canada) many thanks to those who tried

the socket that is part of the camera

I picked up this camera second hand on ebay and it actually works. Alas no manual, I've googled, yahoo'd to no avail. I did find the Vantage web site but this model must be so old it isnt listed. has anyone any info about dip switch settings and the other controls please before I start playing

Does anyone know if Vantage is a renamed brand?. (ie Sensormatic are baxall)

I had a thought after my last post (as the cam also accepts 12-30VAC). (quick rummage through my xmas decorations lighting box, aha! a 24vac class 2 transformer.) connect it up, turn on and all working within 10 secs. So either the auto AC/DC switcher isnt working properly, or as the camera is rated 11 - 40 VDC needs more than 12v

the camera is rated 5W so <0.5 amp. I am using a 12VDC 4A supply. I have tried other supplys as well.

1 1/2 mins black/white flickering 2 mins of black screen 1min inverse picture 2mins picture slowly appears until normal some screen shots

Can anyone suggest software to view multiple avtech 760's at the same time. NUVICO cannot find the 760 many thanks

when somebody types into their browser the address you created at dyndns, Dyndns will then redirect them to your IP address. Providing Java script is enabled, the log on screen will appear.

I use the same model and firmware vrsion. using a 750GB HD is get about 11 days recording using best and frame settings

I have used some of these lens before, and seem ok. only had one damaged in the post which takes up to 10 days from HK.

thanks. it is quite possible it was due to disconnecting cameras whilst still recording. All seems fine since I stopped recording, powered off for a few minutes , powered on and started recording again. I didnt do any hardware resets.

I have been using 2 avtech DVRs for some time now and things have worked well. when viewing in quad view each cam is numbered 1 - 4, when I do a netwrk backup I enter the cam number and view that cam. Now all of a sudden when I backup up cam 1, I get footage from cam 4, the same goes for the other cams, 1 is 4, 2 is 3, 3 is 2, 4 is 1, Any suggestions please

try following the help I gave here http://www.cctvforum.com/viewtopic.php?p=85316#85316 might not all help, but some may.

I use the avtech 760 and view it over my home network so backups of recorded data is straight forward, from there I can burn to DVD or USB. The only problem is all recorded data is in a proprietory format, which means you have to use a specific program to view it, (there is a built in converter to AVI but the quality is absolute CR**. In the past when I have given recorded data to the police, I have used my laptop with a TV input card to record from the "DVR video out" to make a recording in WMV or MPEG format so it can be watched more easily. camera quality makes all the difference CCD is better over CMOS, 1/3 over 1/4, Pixelation. day pics are fine, but night time in very low light the pictures do become grainy, but unsure whether more expensive DVRs are any better. here is day here is night under a orange streat light By junglejim42 at 2008-07-07

Well for a start, if they are all the same make/model they will all have the same default IP address, (avtech 760 uses 192.168.1.10) so after reading your manual, you will need to hook up one DVR at a time to the network, log on to it using the default IP address and then change the IP address. once the IP address is changed then do the next one and so on. use IP addresses high up so not to conflict with other network devices. Note: If you cannot log onto the first DVR, check that your network is using the same IP range i.e. 192.168.1.***. routers do vary.

Has anyone used/got experience with these 1. At the bottom of the picture above " SW80" there is a motor driven worm wheel, what is it for, how is it controlled if required. 2. Also the Line lock buttons next to the dip switches what are they for. 3. The lens holder is a quick release type, this unit came with the green module (13mm x 1.0 thread), I need to find the Black module (I think) (12mm x 0.5) does anyone know if they are available without having to buy the lens as well. I cant find anything in the 17 page booklet that came with it!

many thanks.

Here in the UK all vehicles have reflective yellow rear number plates. Using an Avtech 760 and Pecan 520TVL hi res 1/3 ccd B/W cameras (great during the day) all I get at night is white out for the number plate due to the reflectiveness. Any suggestions how to over come this would be welcomed many thanks

more than likely a firewall problem.

Just a thought Is the IR internal, I ask because photo sensors are affected by IR light, so even though you cannot see any visible light, light is there as soon as you cover the dome and the IR turns on. I presume that you have the cover off the dome, if so, disconnect the IR (without voiding you warranty)and cover with blacket again, if cam switches to b&w then you know you are getting IR leakage

Eeeek, my knowledge of DVR card servers is limited, but in the software there must be a means of setting up online passwords, there should be a "admin" and a "guest" account as default. guest accounts normally have a simple password like guest or 0000. I should imagine there could also be problems trying to view the server from the same PC (hense the black screens). If you have another PC/Laptop on the same network open a browser window and type in the IP address of your server without the HTTP://www i.e. 192.168.1.??? and see if you get any pictures
