What is a DVR?
DVR stands for Digital Video Recorder. The digital video file format is very large in size which is compressed in different types including MJPEG, JPEG2000, and MPEG4. New generation DVR’s use H.264 compression and our H.264 compression has been modified to provide the best picture quality over other DVR manufacturers. The DVR can record up to the maximum amount of channels specific to the system. Our Hybrid DVR supports 4, 8, 16, 24, 32, 48 and 64 channel Analog/IP Camera configurations and can record up to 30 FPS on all channels at different resolutions.
What does FPS stands for?
FPS is an acronym for frames per second. In NTSC (National Television System Committee) systems, the maximum allotted FPS is 30, and in PAL (Phase Alternate Line) systems the maximum allotted FPS is 25. In real time mode the DVR can record and display a maximum of 30 FPS per channel.
What are the Standard DVR Resolution Rates?
- NTSC:
- 4CIF = 704x480 Pixels
- DCIF = 528x320 Pixels
- 2CIF = 704x240 Pixels
- QCIF = 176x120 Pixels
- PAL:
- 704x526 Pixels
- 528x384 Pixels
- 704x288 Pixels
- 176x144 Pixels
What does Resolution mean?
Resolution is the number of pixels (horizontal x vertical). In a NTSC system, the maximum resolution is 704x480. You can select the resolution to increase the recording capacity, so with lower resolution and lower FPS you get more recording time and hence less usage of disc space.
Can I set different camera channel on the DVR with different recording rate than another?
Yes. Our DVR allows you to select the camera FPS and resolution; each camera can be set to 704x480 @ 30 FPS max in NTSC mode & 704x526 @25 FPS in PAL mode for optimal performance.
What if I accidentally go over the maximum FPS on the DVR?
The DVR built-in software settings in the camera setting tab will allow you only up to 30 FPS per camera or lower so you cannot run over.
What types of cameras can I use with your DVR?
The DVR supports Analog/IP cameras. For analog cameras you must use BNC input connections, so any analog camera that has BNC support will work with the DVR. For IP cameras please see our IP cameras support document.
What does IP stand for?
IP is an acronym for Internet Protocol that allows digital computers to communicate over long distance.
How can I view the DVR from another location?
Our NVR (Network Video Recorder) Client software comes free with the purchase of our DVR. Our NVR Client software supports up to 64 channels at once with unlimited features and up to 128 different DVR Server connections. You have to check the firewall settings and enable port forwarding. We have a Web Client to access the DVR Server remotely with limited features.
What is Port Forwarding?
Port Forwarding is a term used for gaining access to a network resource from outside the internet. Since the NAT of a router hides your computer from the internet, the router has an option to specify port numbers to specific computers inside a network that you can give access to. This enables you to access the DVR functions and view the video from the internet.
What are the default port numbers for your DVR?
The default ports are: Remote Port = 5100, PDA Connect Port = 5101, Alarm Send Port = 5300 and Web Port = 80

What are IP based security cameras?
IP based security cameras transmit a video stream directly through an existing network.
What is special about an IP based security camera?
IP cameras do not need any extra components, just the IP camera and the DVR. Most IP cameras support PoE (Power over Ethernet) which comes from a network Hub/Router that can be purchased separately. With PoE you do not have to run a separate power line to the camera.
What are the advantages of IP based security cameras?
Our supported IP based cameras and our DVR use the same protocol; our remote client viewing software is able to view the video stream of the camera.
