A:AnswerYes. The lag was pretty bad 1-3 seconds. Someone had enough time to drive up, smash my car window, and grab a bag. Unfortunately I found a beta update that addressed most of the lag issues after my car was broken into.

This seemed to have lessened the lag to about 1 second or less.
A:AnswerYes you can change the post time from 30s, 1min, 2 min, and 5 min. I don't think you can alter the "pre" time unless you have it scheduled to start recording at a specific time.
A:AnswerYes, all new items come with a one-year manufacturer warranty. Please keep in mind proof of purchase (receipt) is required to file a warranty claim.
A:AnswerYes, you can install this system in a house that has existing wiring for this kind of camera, or install it in a location that does not have existing wiring.
A:AnswerIt should use the same BNC based cable for the cameras to the DVR, it will probably use the same power source connection, but I would have to know the exact model. to be absolutely sure. It should fit 960H, 720P, 1080P camera systems
A:AnswerI think you would want to contact Swann or view their homepage instruction to answer this question. There is still a mouse but I have never found them very hard to use to set up, once set up, you can use google assistant to do the basics.
A:AnswerOf course it does, the instructions include the links to install and set up your cameras and DVR at Swann website. They offer a support center on the site as well as live help and the most asked questions. Plus you can join the Swann Support Community.
A:AnswerYou can record any moment saved on the DVR in video or snapshots to any Flash Drive. They can either be recorded in AVI or MPEG4 (MP4) for better quality. As far as cropping, computer software will allow you to zoom in or crop snapshots
A:AnswerThat is limited by the App not the DVR, however it really depends on your internet speed both upload and downloading. Each person logged on trying to view will slow the live camera feed down.
