@Scorpion Sorry, can you explain what the difference is between the I.R camera you recommend versus the one you don't rate.

http://www.avtech.com.tw/english/cctv.aspx?Type=3&Type2=3 This DVR seems to be new to market - Avtech 792 Has anyone used one yet? How does H.264 compression compare to Mpeg4 during playback? Is their much difference? This DVR seems good value to me at approx £350, what do people think?

I have swapped this camera with an identical one Ihave located else where. The interference has 'followed' the original camera to the new location.

I have tried numerous combinations to isolate the interference. Tried another cable - Interference still present Tried Camera straight into monitor - Interference still present Moved camera to different location - Interference still present I have come to the conclusion that the camera itself is causing the distortion. When the camera is disconnected, then reconnected it takes 30s or so for the intereference to appear. Once it first appears it then progressively gets worse for a minute, almost as if 'some charge' is building in the camera. Have I just got a faulty camera?

Here is a example screenshot showing the diagonal distortion. The image is at frame resolution 720x576 at 6fps, yet the image isn't that clear to me. Is that down to the compression on the DVR?

760A Real Time 4 CH Digital Video Recorder http://henrys.co.uk/cctv/videorecorder.htm Alternatively what about the 4 channel version of this DVR http://www.wecl.com.hk/digiguard/specifications.htm Specifically I'm concerned about the quality of playback from a recording with regards to the compression. As whilst they both offer resonable resolution, if the compression is poor so will the recorded image. Do these offer a decent picture in playback compared to similar priced DVRs?

In a retail scenario, where do people store their DVR's? Are their any locking cases available for under £80?

Doesn't appear to be badged up as a particular brand! I'm guessing its based on or is a unbadged Avtech

Investigated further 6204U only seems to over recording at upto 720x288. So not ideal How about - 760A Real Time 4 CH Digital Video Recorder?

Will add a link to product

I'm looking for a PVR for use in a small retail store. Has anyone had any experience of this product? 6204U 4 CH Digital Video Recorder Thanks, Stuart.

The cable goes from the Camera to Dvr in one strech, it travels about 6m - though the cable is 20m long so their is a coil of excess. I will try connecting the camera direct to a monitor, that is close to the camera and see if that results in a improvement. That should give me an idea wether the interference is from the camera or cable. I will report back, Thanks.

I'm using pre-made BNC cables. I've got 1 5amp power supply with a splitter for the cameras, and a seperate power supply for the Dvr. Both power supplys feed from the same wall socket through a 4 way adapter.

Hi. I'm in the process of installing CCTV into a store. It will be a 4 camera wired system with a Dvr. I've currently got 3 cameras installed, 2 on the shop floor and 1 in a store room. On 1 of the shop floor cameras I am getting interference on the image. The interference is in the form of wavey scrolling bars the roll diagonally across the image. The cable for this camera goes across the store above the atificial ceiling. Any ideas what is causing this inteference? Thanks, Stuart.
