This review is from: D-Link HD DCS-4701E Vigilance HD Day& Night Outdoor PoE Mini Bullet IP Camera
Pros: Better image quality than the (consumer grade) DCS-23xx series cameras.
Wider field of view than the DCS-23xx series cameras.
Improved night-vision range over the DCS-23xx series cameras.
Power Over Ethernet (PoE) can be highly leveraged in some situations. It is the factor that most influenced my purchase decision.
Cons: No audio.
No local storage (SD card)
No passive infra-red motion sensor
No support by the (consumer oriented) MyDLink app
More costly than D-Link cameras that offer those features
Other Thoughts: This camera is part of D-Link's "professional" range of cameras. Presumably that is why it is more expensive and not supported by the MyDLink app.
I would recommend this camera only if its relatively limited feature set aligns well with your needs. If D-Link offers a similar model with more features (particularly audio support), I would consider purchasing such a hypothetical model. I will not likely purchase another DCS-4701E.
Pros: High capacity, good performance, reasonable price.
Cons: Two out of two drives failed within their first ten days of operation. I lost a considerable amount of time and effort (but no data!) in diagnosing these failures. Both drives passed the WD Data Lifeguard diagnostic tests at the time of initial installation.
Other Thoughts: After four years of stable operation, a bad block turned up on one of the drives in my system system containing three 1TB WD1002FAEX drives. That drive failed the WD Data Lifeguard diagnostic tests. I returned the failing drive to WD for warranty replacement. Since I was looking for more capacity, I purchased a 2 TB WD2003FZEX drive from Newegg. After installation, that drive passed the WD Data Lifeguard diagnostic tests and worked well for almost 10 days. At that point, the system started experiencing intermittent hangs and pauses. Errors appeared in the Windows event log. The new drive then failed the WD Data Lifeguard diagnostic tests. I returned the new drive to Newegg for replacement. After installation, the replacement drive passed the WD DLG diagnostic tests and did not generate entries in the Windows event log. However, when copying data to the drive and running a file comparison program, I got compare errors. I repeated this test (30,000+ files, 56+GB) many times. While the S.M.A.R.T. data showed the drive had not experienced high temperatures, the problem may be temperature related. Early in the day (lower room temperature), I would get no or only only a few compare errors when copyng 30,000+ files. Later in the day (higher room temperature), I would get a few dozen compare errors when copying 30,000+ files. I did not get any errors when running the same test on other drives in the system.
At this point, I have lost confidence. I returned the replacement WD2003FZEX drive to Newegg for refund. I just can't afford the time and effort of yet another cycle of drive installation and diagnostics. I'm going broke paying for the return shipping charges.
From what I know of the industry, premature drive failures do happen, but the probability of getting two consecutive bad drives should be very ... VERY ... small. I really don't know if the problem lies with Western Digital, Newegg or my system. I really think that the issue is WD or Newegg and not my system, but I know that I need to remain open-minded to all possibilities.
On the bright side, I am happy that Newegg's return policies allow me to get out of this seemingly no-win situation with only the loss of those shipping charges.
Pros: Reasonable price (but more expensive than the Rosewill card that I tried first). Still working well after more than 90 days. Provides throughput expected from USB3 and does not produce errors when used with WD My Passport 2TB drive.
Cons: More expensive than the Rosewill 2-Port USB 3.0 PCI Express Card Model RC-505.
Other Thoughts: My initial experience with the less expensive Rosewill 2-Port USB 3.0 PCI Express Card Model RC-505 was not good. NewEgg support went the extra mile to resolve that issue. Thank you Newegg!READ FULL REVIEW
