Has anyone ever tried this?
why? even with a shit ton of cameras your only using a fraction of the speed of most spinning disks.. just a couple MB/s for most.
I know SSDs and NVRs should never be mentioned in the same sentence, but it's not its speed that I'm after, believe me, it's the fact that it doesn't emit any sound lol. Wouldn't it be nice if there was even one made for NVRs then no one would be bitchin' about the sound of spinning disks in their room?
buy purples, they 5400rpm.. you wont hear em unless u use it as a pillow
Put one in there and let us know how you make out. LOL I think it is coming down the pike but on the consumer level we are not there yet. The fans in the NVR's are usually louder than any hard-drives. If my NVr was driving me nuts I would just move it.
I already have that. But the humming still annoys me --- to be precise, it's the 'hollow' or 'echo' effect that goes with it that bothers me a lot. I'm beginning to suspect that the NVR casing has a lot to do with this. Will try foaming the screw mounts first then putting sound deadening tape on the metal casing and see if this will cure it.
...or I could just unplug the fan from the board and settle with passive cooling...or better yet...get me one of those 6' shielded sata3/power cables and hide the drive inside a hollow drywall.
I'd figure that you'd hear more noise the clicking of the read/write heads than you would of the actual platters spinning. Isn't continuous recording going to wear out the circuitry of SSDs a bit faster than normal usage? I haven't kept up on SSDs too much, and I remember they have a limited read and write lifetime, that they were working on improving.
this is one reason why I suggest external PoE; so you can put the NVR some place away from your wiring point.. you can hide the NVR some place it wont be heard, or most importantly.. found.
I thought that was common practice anyways =) It's like, hey, if you wired everything to terminate in an area where you're gonna see and or hear the D/NVR, then you have to deal with the noise, eyesore, and it possibly getting pinched.
Yes, I'm aware of all of that.
I knew you'd say this, Nayr. I think this is the 2nd time I've heard this from you lol. Do you think it's feasible if I hang the NVR inside a drywall cavity (between wall studs faceplate up and rear facing down)? Will that be a suitable position for the hard drive? Of course, I'll make a door-like cutout on the drywall for this. What do you think?
I forgot to add...would probably have to install a fire block above the spot where I'll hang the NVR just to be safe and add vents perhaps. Don't know if this will be up to code.
you need to allow air to circulate, at least through natural convection.. meaning some place up high in the void for warm air to escape, and some place down low in the void for cool air to replace it.
if you just seal electronics off in a closed space, you'll get thermal runaway.. my LPR camera was hitting 150 degrees inside with IR off; then I drilled a few holes and remove the PoE splitter so it had less heat and more airspace.. now I never see more than 105F in the middle of the summer w/IR on.
150º!!?...that's about the average temperature in our attic come summertime.
a lesser camera would be toast; but infact my LPR camera is rated up to 150 degrees and took it with stride.. I was using an indoor/outdoor cheap digital thermometer with the probe shoved into the birdhouse before I put the lid on.
for passive cooling you want an intake several times larger than the exhaust.. so its not trying to create a vaccume with lower pressure in the wall.. I forget the actual math, but IIRC its ~3x
Tips: If you hide something in the wall, make sure its well ventilated. If it has a fan and a spinning motor (disk), make sure it is mechanically isolated from the house structure so as to not become a speaker. Oh, and make sure you can service it without rebuilding the wall and One more, leave a bated rat trap in there just for good measure with something like a walnut as bait.
Extra silence can be had by writing to a small SSD (512GB) continuously (say for 24hrs or more), then have the NVR move it to the HDD at some time (or use cron) for your normal retention time, which keeps the disk from spinning except briefly once a day or so, and keeps the budget in check.
I wonder how long a SSD will last if used for temporary video recording?
FWIW, I use a small SSD for the OS and BI, and a 4tb purple for recording storage.
Its in a back room, so I don't care about noise. If I did, there are lots of places that can help you make a silent (or very quiet PC). For home theater PC's, its a big deal, so those guys have done a lot of work in this area.
SSDs are evolving quickly in the market as they march over HDDs in certain (but growing number) of markets. It is inevitable. As far as i know this market (low retention value steaming video write) is not yet at the forefront and as such is suffering an obvious hole in the product offerings, that i feel it actually will satisfy quite well soon with a low cost MLC 3D medium endurance (non-enterprise) product line. For now the endurance specs are all over the map. In general, however, so long as the size of writing / size of the drive is greater than a couple of days and the drive has a normal warranty, you should get more than 500 days (SWAG). What is desirable is to acquire one with a write endurance above 0.5 drive writes per day and a warranty of 3-5 years.
A name brand SSD will generally warn you well before the thing dies, giving you time to swap it out, so as long as you didn't place the OS on the media drive (separate smaller SSD), you should be fine.
Rule one: do not place the OS on the streaming media drive
Rule two: don't wine to me if it doesn't work out :0)
Rule three: spinning disks are cheep, so use only the amount of SSD that you need and go big with HDDs
Your gonna hear the fan probably more than the HD. Just get the purple like nayr said.
I have a small NVR appliance with an SSD installed. It's been working fine for a few weeks. My reason for the SSD is environmental. The NVR is in a weather-tight box located in a field. It's subject to considerable temperature variation. I thought the SSD would be better able to cope with the temperature changes.
