The backbone of our home CCTV system consists of a few hardwired analog cameras connected to a digital video recorder which keeps approximately 2 months worth of footage on file.
The recorder itself is isolated from our network, and it’s multiplexed feed is fed out to the usual array of internet thingamabobs by an encoder, and to all the TVs in our house by a modulator that converts the composite signal from the DVR to a specific TV channels frequency.
This allows me to access the video feeds remotely, but in a worst case scenario means an unauthorized user could access the live feeds, but would be unable to access the recordings or recorder itself.
I’m no network security guru, so both the alarm system and the CCTV system have this sort of “one way” (or “look but don’t touch”) relationship with our internet enabled home automation systems to prevent people smarter than me from ruining my day.
I have, however, been remiss with maintaining the DVR basically leaving it alone for the last four years happily recording 24/7/365 – so when I went to review video this morning to check the effectiveness of the new LED flood lights (I replaced the old 150 watt bulbs in the security lighting with 75 watt equivelents that draw 14 watts a piece yesterday) the system crashed…HARD.
This ended in my replacing the 1TB drive that was factory original with a 2TB I had on hand, and paying just a bit more attention to the system maintenance and scheduled restart settings the DVR has.
Guess I’ll have to wait another day to check out that lighting.
