After our first investigation at the Walking Horse Hotel we wanted to expanded our coverage from one to camera with a DVD recorder. The Swann 4-Channel DVR gave us that as we prepared to investigate Octagon Hall. We bought it through QVC as a bundle with four IR 580-cameras, four BNC cables and a 7inch TV. We got extra cables.
The DVR was already setup to run when we got it. We had to install some software so we could convert the recorded files over to AVI's. If you follow the directions setup is pretty simple. You have to spend sometime going over the directions in how to record and downloading the files to a flashdrive. It came with 4 60ft cords which gave us some versatility on where we wanted to place our cameras.
Pros: More coverage and being able to record for hours non-stop unless you switch it off.
Cons: In close spaces you can see the room clearly, however, it is very pixalated on playback. If the room is large the IR strength weakens so you don't get to see things. No matter how much you brighten the video or change the settings. It still is worthless.
Fix it: We bought IR Sima light, Phantom lights, UV light and all of these helps in bigger spaces, but not the clarity. I got a IR heat lamp light and that seams to work as well only you loose the IR from the camera because the room is brighter.
The bundle QVC offered is sold out at this time. They do offer others, so remember to check out the reviews from other customers before buying.
