| Storage Capacity |
|
At the maximum frame rate (30 fps) this DVR will use approximately 5 to 7 gigabytes of hard drive space per camera, per day. Therefore, on a 500 gig hard drive with all 4 cameras hooked up you can store about 18 to 24 days of recorded video. The use of record time scheduling and motion detection can extend the recording capacity up to twice this amount. You may also tune down the record frame rate to increase your recording capacity (however this may affect video picture quality). Once the hard drive is full the unit will start recording over the oldest video.
You may upgrade the HDD storage on this machine up to 1000 gigabytes (1 terabyte).
Please keep in mind that actual storage capacity varies greatly based on many factors including the resolution and imaging chip size of each camera, the amount of motion in the field of view, and of course the selected DVR features and settings such as the frame rate, scheduling, and motion detection. Recording audio will also use up storage space (approx 1-2 gigs per audio input per day).
Be careful when comparing our storage capacity to other DVRs. Often times other manufacturers will claim that their DVR will allow you to store months of video. Be aware that they may be assuming that the frame rate is turned all the way down to one frame per second which is not a practical setting to use.
