Magnetic field and the batteries

[ronnedith]

I was wondering if Netgear or whoever magnufactured/designed the Arlo camera, performed a study on any possible negative consequences of having the mount magnet so close to the batteries? Perhaps this is currently draining the batteries a tiny faster than usual?

Electricity and magnetism are closely related through Ampere's Law: the physical law that describes how electromagnets are created by running current through a wire to create an electric field. The reverse is also true: a magnetic field can also produce a current via induction, which has the potential to overdraw a battery of an electronic device. However, though any current is capable of generating an magnetic field, only a change in magnetic force -- otherwise known as "flux" -- can produce a current, as per Faraday's Law. A static magnetic field will only produce a drain for a split second.

If it does, the amount is prob so small it doesn't make a diff.

My OEM batteries run 3.5 months always on best video at about 5 mins per day.   Two cams used under spec (< 2-4 mins per week ) lasted 7 months on OEM.

( used only for motion detect inside )

Problems with short life of batteries fall into a few categories; 1) excessive use 2) bad set up or location 3) defective.

1 and 3 are obvious... 2 is a bit harder to explain but can be interference, base drop out, distance from base, excessive IR activating motion, etc.
