a cctv camera / security camera, with correct motion control recording software (dvr hardware/software), like setup hooked to security system. more likely trigger things better long term. majority of the cctv camera dvr setups, you are able to "select" what part of the camera feeds actually trigger a recording / turn on lights (disable portion of screen were there might be a tree or some flowers), and you are able to adjust timing of everything for how long things are on.
CCTV cameras, more so outside units, tend to come with some sort of "fan" to cool them down, and then perhaps some sort of "sun shade" per say to keep the hot sun off them along with rain off them. and in that the CCTV camera more likely to work longer.
with motion sensors. battery ones, i never had any luck with. and better wired directly to a power source either through lights themselves or to security system / home automation setup.
not a large fan of motion sensors. due to they fail way to easily here in central IL, generally nasty cold winter ice/rain/snow/sleet will take the sensor out, or a nasty hot summer and pure heat will fry the motion sensor circuit boards. and then the more cheaper combo motion sensor and flood light units, flood lights heat up, causing circuit to heat up, and pre-mature death.
some of the more expensive combo motion sensor, light setups, you can wire in series, and they give extra spots to include wiring, to run them all in series / parallel setups. for either sensors and/or lights. but you are at the mercy of cheap circuit boards. i would say head to local large hardware store, menards, lowes, homedepot, and look at what they have to offer, and if need be open a box and check instructions / manuals / wiring options.
============
home automation hardware/software be next thing to look at if not, "security system"
