Security DVR Recording Resolutions
Friday, March 19th, 2010How To Set Up Your DVR For Recording
Tuesday, November 17th, 2009Keep in mind that all DVR’s have different configurations and terminology. I will explain how to properly set up the Elite, Elite-Mini-HD, and Ultimate DVR’s for recording while conserving maximum storage. Most DVR’s will not have as many options for recording configuration, but this should cover just about every setting you will find.
In the Elite, Ultimate and Elite-Mini-HD series DVR, every camera has its own configuration. Unlike most DVR’s, you can set each camera differently, or they can be all the same. Most other DVR’s have only one setting that applies to all the cameras at once. Let’s discuss each setting individually.
The Difference Between CIF And 4CIF Resolution
Thursday, August 13th, 2009
When configuring your DVR for optimal recording, there are many options you will be considering. Among them is the resolution you want to record in. While most DVR’s can record in CIF resolution (360×240) at the maximum frame rate provided by the DVR, some can also record at higher resolutions by reducing the frame rate. For example, you may be able to record on any channel at CIF resolution at 30 frames per second, but then you would probably only be able to record at 7.5 fps per second if you changed the resolution to 4CIF (704×480). You will have to decide for each camera (assuming your DVR has independent resolution settings for each channel) which resolution you want to record in. Remember, what you see is not always what you get! Most DVR’s will display live video in 4CIF or D1 (720×480) resolution, but they are often recording in a much lower resolution.
The Relationship Between The Camera TVL And The Resolution Of The DVR
Saturday, August 8th, 2009Here is a very common question. How many TVL should the camera have to best use the resolution of my DVR? This is one of the most misunderstood relationships in CCTV. The resolution that the DVR records in refers to the SIZE of the image being recorded. So CIF resolution (360×240) and 4CIF resolution (704×480) refer to how large the image actually is. 4CIF is an image that is 4 times larger than CIF.
