Surely with the intrusion detection area or line crossing you can reduce false negatives?
I do currently have one outdoor Everspring SP816-1 motion sensor at the porch.
Works well but it is battery operated as you say.
Which zwave motion sensors do you use?
some very cheap no brand chinese or something. They work very well, even under 0 C. Here in South Italy it’s just 10 days in a year, so batteries last 12-18 months.
I’ll probably add more things in the garden this summer, so I’m planning to migrate to a non-battery option. but if you’re OK with batteries, those are OK.
The following POE NVRs all have 4x alarm output ports:
8ch
DS-7708NI-K4/8P [broken link removed]
DS-7708NI-I4/8P [broken link removed]
16ch
None POE models with 4x alarm output ports
8ch
DS-7708NI-K4 [broken link removed]
DS-7708NI-I4 [broken link removed]
16ch
K series are the cheaper ones but have version 3.4.x of the firmware. The I series are more expensive and have the later version 4.2.x firmware.
EDIT: Apparently at some point the K series did get the version 4 firmware but Hikvision have since pulled it.
I got a new Hikvision DS-2CD2045FWD-I IP cam delivered today, my first one. Using the Hikvision plugin for Vera and a bit of tweaking, I now have a working motion sensor device in Vera for the camera. See here.
