CAMERA KNOWLEDGE
INGRESS PROTECTION (IP RATINGS)
The IP rating is used to specify the strength of the enclosure that surrounds electronic equipment and is determined by specific tests. Each IP rating consists of using two separate measures. The first is protection against solids; the second number is protection against liquids. So therefore an IP rating of 65 is totally protected against dust and is protected against low pressure jets of water from all directions with limited ingress permitted.

Example: 4 channel DVR, at 768kbps bit rate, an hour recording for 4 channels is 1.29GB, or a 500GB HDD can probably record for about 15 days
Note: All numbers are approximate and are for estimating only. Many factors influence actual storage capacities including size of data, quality, aspect ratio and compression used.
