DVR

Prology iReg-7570SHD

Compact DVR with Ambarella A7LA70 and Omnivision OV4689. Have small LCD with plastic cover and tiny accumulator. Also have external GPS in the middle of the power cable. GPS and DVR holder compatible to Koonlung C-series DVR. Some special “soft touch” plastic that looks like leather on device’s front. Loud speaker. SDXC support. Work with exfat 128 GB cards. It is hard to release DVR from holder even using 2 hands. Device is not compatible with iPad and Lightning to SD Card Camera Reader because of long filenames (maybe fixed by firmware customization, see end of the post).

Video quality is OK as for the 200$ price.

No Comments on iPhone 6S first impression

iPhone 6S looks absolutely like iPhone 6. Difference is in letter S an the phone back.

S letter on iPhone 6S

And color of camera lens. It seems like kind of optical filter added to 6S.

Apple Touch Id 2

Photo have better resolution (12MP). Video have better resolution (4K). SLO-MO have the same 240 fps at 720p.

New feature Live photo is quite interesting. In addition to photo iPhone store couple of seconds of video. Video is up to 15 fps, with 1440×1080 resolution. Can be imported on PC as a .mov file with same name as photo. Video MPEG4 AVC/1440×1080@Variable(upto15fps) Audio PCM/44/16/mono.

3D Touch is also nice. It is actually an another dimension of the user interface. Interface of 6S now react on how hard you push. It may be simple context menu or preview/open depend on force of a touch.

No Comments on WD Red NAS Hard Drive 4TB

After 2.5 years of usage, my old backup drive (Seagate Barracuda Green 2TB) failed. Drive usage was minimal, but it was on 24/7. New disk decided to be NAS specialized 4.0 TB. Since I believe, it will be backup for this and next generation of home storage. I hope it will serve more than 2.5 year. So this time disk is WD Red NAS Hard Drive 4.0 TB WD40EFRX.

Before start using it as eSATA backup did some speed tests using USB 3.0 connection to Windows 7 PC.

Weather station that always show 20% RH

3 Comments on Weather station that always show 203 RH

Relative Humidity Sensor. Detail in weather stations that live only about couple of years. It looks like:

Size may vary. It may have different number of black lines but it always work same way and got broken same way. Special coating on sensor getting old and disappear. When it happened there is always RH=20% on weather station display. Why not RH=0%? Because this type of sensors cannot measure RH lower than 20%. Therefore, when it got broken there is ~20% RH on display.

RH Sensor must be replaced to fix the issue.
