adrien33 0 Posted April 24, 2011 Hi, i'm working on a project using 4 cameras placed on a vehicle to record continuously a video footage to create a legal material when there is an accident. This video footage will be sent to a SSD Hard Drive. I was wondering about the amount of memory i will need to be able to store this type of footage. thanks a lot !

SDM Group 0 Posted April 25, 2011 All depends what type of compression you are using, how many fps and the quality settings. What type of cameras, IP? or DVR are you using? Share this post Link to post Share on other sites
thewireguys 3 Posted April 25, 2011 What model SSD are you planing on using? Share this post Link to post Share on other sites
adrien33 0 Posted April 25, 2011 About the SSD, I have no clue because i just have to write down how the system works, I don't have to create it in real. The cameras are sort of spy cameras so I think it is DVR. The quality does not require to bet in high definition. The resolution is between 352*288 and 512*582. i don't need a precise amount of the data required for the SSD but just an approximative number.

NotoriousBRK 0 Posted April 25, 2011 Depending on compression method and settings, you will use between 500MB and 20GB per camera per day of recording. Share this post Link to post Share on other sites
adrien33 0 Posted April 25, 2011 Okay thank you for your answer. Can you give me the settings for 500 MB and 20 GB please ? Share this post Link to post Share on other sites
NotoriousBRK 0 Posted April 25, 2011 Okay thank you for your answer. Can you give me the settings for 500 MB and 20 GB please ? Keep in mind these are approximate, as the final answer will depend on exactly what equipment you use: 500MB/Day = 320x240 recording at 2fps, encoded at ~40Kbps, h.264 Video at this size/rate will show obvious compression artifacts and loss of detail, but would be generally sufficient to prove timeline and chain of events (eg: vehicle 1 collided with vehicle 2, passenger in vehicle 1 exited under their own effort). 1.2GB/Day = 640x480 recording at 5fps, encoded at ~100Kbps, h.264 Roughly the same results as above, but with more frames and larger image size. 8GB/Day = 640x480 recording at 15 fps, encoded at ~750Kbps, h.264 Video is relatively fluid and shows little apparent loss of detail from encoding. 16GB/Day = 640x480 recording at 15 fps, encoded at ~1.5Mbps, MPEG4 Video is relatively fluid and shows little apparent loss of detail from encoding. 20GB/Day 640x480 recording at 5fps, using MJPEG Video is less fluid, moderate detail. 40GB/Day 640x480 recording at 15fps using MJPEG Video is relatively fluid and shows little apparent loss of detail.
