If you’re going to keep any of the footage from your security camera system, you need home security cameras with DVR. Obviously you don’t really have the time to sit around watching your video surveillance monitor every second of the day. DVR allows you to go back and review or check in on the live streaming for your camera system. This is how a DVR basically works for home security cameras:
DVRs record the surveillance footage onto a hard drive so that you can later review the information stored there. What the camera records will, of course, affect what the DVR is able to store. You can’t ask a camera DVR to record something that it doesn’t have the features to do. Some of the things you can do is adjust the recording sensitivity for every camera in your system, tell the cameras what they should record (e.g. blockages and loss of signal), choose between continuous or motion-detection recording, install backup, and more. You’ll also want to set up your remote viewing of the recording device so that you are notified your preferred way, whether that’s email or text or something else, when there’s something you need to see.
If you need to review any footage, you need a DVR that is capable of providing this. Here are the kinds of security camera DVRs: Stand-alone, PC Based, PCI Video Capture Card, and HD-DSI DVR. For most of these, you can have either 4, 8, or 16 channel camera systems with one camera on each channel.
A stand-alone DVR will provide you with all the basic recording, live and remote viewing, motion sensing, and playback features you need. The basics are often more than enough; you can find recording rates up to 480 fps, plus a terabyte of storage space on the hard drive.
Using a PC tower, this DVR will record with a video capture card and place the data on the hard drive. This is the exception to the “4, 8, or 16 channels” rule – you can have as many as 32 channels AND audio feeds here. Your HD frame rate will be no higher than 960 fps, but you can have as much as a full terabyte of data storage.
PCI Video Capture Card
The PCI model has a video capture card that you can put in your own computer to make your computer the DVR. This is additional exception that also allows up to 32 or even 48 channels and audio feeds. Maximum fps will be around 240.
With this model, you’ll have a top of the line security camera system. HD 1080 pixel resolution with 2 terabytes of storage and a 90 foot range of night vision, you can find some of the best security cameras here if you’re willing to spend a bit more.
Home security cameras with DVR come in multiple formats. Make sure that the one you choose will best fit your needs. You can always talk to a home security professional to find out more details on the kinds of DVRs available for home security camera systems.
