    Zombie comes for a visit

    A Zombie walked up my long driveway. The video shows maybe 1/4 to 1/3 of the length of it. I never saw this guy before. I don't think he's looking to steal stuff. He'd have a hard time carrying anything. And he probably couldn't run away, lol. I sometimes let my dog run loose, since our...

    Two cams with 12mm lens, but VERY different FOV. Why?

    I had a 4MP cam with a 12mm fixed lens watching my driveway. I was pleased with the FOV, but wanted better nighttime images. I decided to change it out for a 2MP Starlight varifocal,, 2.7mm to 12mm. I figured I’d probably set it to 12mm, for an identical FOV. I mounted the Starlight in the...

    Can I Manage the space set aside for recording of Main & Substream?

    So some consider recording the substream to the HD as a waste of HD space. - Live remote viewing on Android (using gDMSS) is acceptable using Sub Stream. Using Main Stream is problematic w/ cellular. (Main Stream is recorded w/ good bitrate and fps) --- Granted, Live viewing of Substream...

    Starlight: Varifocal vs Fixed

    The varifocal Starlight can be adjusted from 2.7mm to 12mm The non-varifocal Starlight is available in 2.8mm, 3.6mm or 6mm, depending on model (if my checking is correct) The Varifocal's motorized lens increases the price, naturally. The adjustability is "worth it", some would argue. But what...

    How can I reassign camera numbers in NVR?

    All, I currently have a 5 camera system. One cam was WiFi. I learned (the hard way) why the experts here say "Go Hard-Wired!" So I disabled the WiFi and now use a wired connection to that cam. The WiFi cam has 2 ip addresses (WiFi + wired). So the NVR thought I connected a new wired...

    Am I making it hard for my NVR?

    All, The NVR has a lot to do. ie: receive multiple streams, create files, write to disc, etc. I'm not sure how various settings I select affect the workload of the NVR processors. Maybe my settings make it hard on the NVR processors. And an overloaded NVR may mean degraded performance...

    Tips to reduce "nuisance" alarms (and false email alerts)

    All, Consider "intrusion detection" tools: - Using the camera's "Motion Detect" feature for an outdoor setting is folly. Too many "nuisance" false alarms. - Using a laser line trip wire is superior. Less false alarms, but still susceptible to falling branches & leaves. - A Bosch or Optex...
