    this dvr uses the Hi3536 SOC (Cortex A17 quad-core@maximum 1.4 GHz) with 1GB of samsung ddr3 1866Mhz (4x K4B4G1646E-BYMA). Vitesse vsc8641xjf Gbit eithernet chip for the internet/lan port. Realtech rtl8325D switch chip (RTL8326 24-PORT 10/100M + 2-PORT 10/100/1000M ETHERNET SWITCH CONTROLLER WITH EMBEDDED MEMORY) for the cameras connected via the two gigabit ports to the hi3536 chip.

    ok i popped in two 8TB WD red drives i got from bestbuy, shucked the usb shell and installed. I got the Thailand drives as they got 256MB sram. booted the dvr and they reported as 7.27TBytes, well first one slightly smaller as the os probably puts a swap(?) partition on it. I only connected one camera, but so far this dvr is much quieter then the lnr280 dvr.

    Now to install and see how they perform...

    So how can one tell if they have the bitcoin miner? I changed my default passwords the day I got the machine. I do occasionally get "illegal login" emails, but that indicates a password fail and looking at logs I never see any log-ins or activity other than my own.

     

    I get thousands of login attempts a week, alarm on the dvr goes off. I log packets to my dvr on my router and then block the ip address. Some times the dvr says the ip is in the private range, the logged packets say otherwise. i believe these attempts are attempting some kind of exploit to get in.

    I wish it would be possible to block admin log in remotely, only at console. But i've changed my admin password to a hardened long password..

    @spotmom: Yes, the pattern is totally correct, every 22 days and I will start receiving TONS of notification saying the camera disconnected. Now, I don't touch it and see how long can it last until it TOTALLY FROZEN (RJ45 unplug or cold reboot needed - according to my initial experience, it should be around 6-7 months)... will let you know.

    Ive had the camera offline issue before, progressively got worse until the power supply failed. replaced the power supply and have only had one camera go offline since in over a year, the 52v rail failed.

    It appears to be a individual camera crashing issue due to power quality issues to the cameras. A cold start on the dvr is required or unplug the RJ45 cable is require to reboot the camera.

    With a IR thermometer, yes the side fan is working.

     

    I'm thinking of blocking the left hand vents so the power supply fan will pull more air across the motherboard from the right side. my fan is small and stands about quarter of an inch from the right side of the case. i'm thinking of creating a wind tunnel to channel air over the cpu from the tiny fan.

     

    The switch chip also is about 130 degree C!

     

    I have 8 cameras connected to the dvr. at night the dvr pulls about 120 watts from the wall, but during the day it is about 57 watts (watts is from memory).

    I logged into hikvision and downloaded hikvision tools and ran the sadp tool which will find the camera on my network. i used a 12v wall wort from an old hard drive to power up the camera. I had to change the IP adress of the camera to something on the class C network ( http://en.wikipedia.org/wiki/Private_network ) and then i could log into the camera. don't declare a port with the ip address (ie. port 8000), just the default 80 web port and change the password.

    How do I get Swann HD IP 1080p Camera to Work on Lorex LNR280 system. Can i do a manual reconfiguration on the Lorex DVR or would it be beter to log into the camera and change the sub-net or even better flash with Lorex firmware. I need help, I don't know how to or where to find the Lorex firmware or flashing software.

     

    I bought the Lorex kit a while back from Costco with 4 cameras and bought two extra cameras and now i want to add two more so i bought the Swann camera two pack for 299 figuring I could get them to work. Got tired waiting for the Lorex cameras to re appear...

     

    please help
