It stands for Digital Visual Interface. Most commonly found in Video cards and LCD monitors for computers. There are cables to connect HDMI out to DVI in for viewing DVD players with HDMI out on monitors with on DVI inputs.

Most Digital Cameras have a basic “Macro” mode for close up shooting. To get the best quality a D-SLR (Digital- Single Lens Reflex) with a 10mm Macro lens would be preferable. Regardless of the camera make sure the pages are well lighted to get the sharpest photo. If you use the Flash on the camera the photo will be greatly over exposed because of all the white of the paper reflecting the flash back into the camera lens.

From what I have been able to find, HD DVR systems do not have any inputs other than the receiver. Unless there is a Video or HDMI “In” there can be no recording to the DVR. This can change at any time as features that customers request are constantly added and integrated into next generation products.

If the specifications page on the site or the packaging list a Lithium-ion Battery than there is a Charger of some form included. Look for the “What's Included” area of the site. If the cameras uses AA or AAA batteries you have the option of using either standard batteries or rechargeable batteries that you have to supply. If it is a compact camera make sure to get extra batteries what ever type they are. Compact cameras drain batteries quickly. D-SLR will give longer battery life but it is still wise to have extra batteries.
