About Camvex DVR's
Our DVR's are built to last longer then other DVR's. We use 'Enterprise AV Surveillance' hard disk drives for video storage. Surveillance drives are more expensive then normal hardrives, they offer more guaranteed operating hours and employ advanced spin down algorithms and use multiple read/write heads to minimize the load the of continuous recording. For our Ultima series we also employ multiple cooling features to improve air flow around hard disk drives to reduce heat, which is a big killer of drives. Using SSD drives with embedded Operating Systems also adds to the reliability of a DVR unit, solid state devices have no moving parts. Most of our DVR's now have the ability to stream live video footage to your iPhone™ or Windows Mobile™ 6 phones.

Maxima Eco DVR range
One of the most costly components of any CCTV solution is the installation of a cable infrastructure.
These costs can be incurred repeatedly if additional cameras or controls are required due to
your changing requirements.
The Maxima Eco can provide the solution to this problem. By installing either four 4 or 8
channel units near a Local Area Network (LAN) connection, you can have LAN access to any
number of remote units and cameras.
Eco units and cameras can be viewed and reviewed from any location that has a connection to

There are a number of settings in a DVR that determine the quality of your recorded footage. Below is a list of DVR settings that have an effect on video quality.
- Recording resolution i.e. CIF, 2CIF DCIF etc...
- Frame rate setting
- Bit rate value and type (VBR or CBR)
- Image quality setting
- Quality of the H.264 encoding algorithm
It should be noted that there is often a compromise between resolution, frame-rate and bit-rate to minimize the cost of storage, because the higher the image quality settings, the more hard disk drive capacity is required.
