Video length timer

Wireless doorbell, which I have had for 2/3 years and am very happy with. BUT, it only records 30secs. As this is not a long enough time in many cases I have been trying to find the settings for this, but with no luck.
Being a " senile old ? " , could any of you good people point me in the right direction for this setting please.

Hello Bob you should be able to go to your power manager settings and either choose optimal surveillance for 60 second recordings or customize recording and choose between 8 second to 120 second clips. Hope this helps.

Spot on answer, thank you. Much appreciated.

Enjoy life.
