I have an Eyeview external dome camera. When purchased it came with a transformer enclosed in a weatherproof box - Eyeview Electronics Model QA-307. Inside the box is a 240VAC - 24VAC toroidal transformer and what appears to be a balun. The box and balun are intact - it is only the transformer that is burned out. I have contacted the company I bought the camera from and they have said I will need to buy a completely new unit (which is quite expensive) - however this seems like a waste of money when the balun and box are still intact and I have adequate soldering skills to wire a new transformer. Unfortunately, when the transformer burned out the sticker with the voltage and current ratings was burned badly also - all I can make out is that it is manufactured by Lung Ho Enterprise Co Ltd. Does anyone know which transformer I need?

As griffonsystems said, if this is a PC-based DVR you should have an option in the computers' BIOS to automatically power up after power loss. A better, long-term solution would be to invest in a UPS so the PC will still have power even if the mains supply fails.

The trouble is, I have no way of knowing what the current requirements of the camera are. I didn't install it so don't know the model and it is mounted atop a 25ft girder that I cannot safely lean a regular ladder against. Also, the end of the girder has been set in concrete so there is no easy way of taking that down, either. I have bought a replacement toroid - 2x115v primaries, 2x12v secondaries. I wired the 2x115v primaries in series for the mains input, and the 2x12v secondaries in series for a 24v@1.67A output. When I read the output with a multimeter it is showing around 26v - would this be within tolerance for a typical PTZ?

Hello, First of all I would like to point out that I know nothing about CCTV or DVR systems (I'm just a lowly PC SysAdmin). I have been asked to find some software or a way of viewing a clip recorded on a CCTV system - I will try to give as much information as I can. Firstly I do not have physical access to the CCTV system itself (it is at another of our locations), but (I believe) it is a standalone DVR receiver. I know not the manufacturer nor where it was purchased nor do I know who installed it (I've worked here just three months). I have been given a CD-R with a *.dvr file on it. The name of the file is StorkBK.dvr, I don't know whether that gives an indication as to the manufacturer or not, but Google returned nothing useful. Is there any software which could possibly open this file or convert it to a standard media type or will I need to buy some DVR hardware for a PC? The little I've been able to gather about DVR's suggests that I will need some DVR hardware if it was encoded with DVR hardware (rather than software). Is this correct?

Update: I've just been informed that it is a PC-based DVR system, if that's any help.
