Hi Cynthia,

Sorry to bother you.

The original RLC-510A in old firmware version was working motions at day time but did not work at night motions, after updating firmware version that new firmware version failed to record motions both day and night time, it is buggy new version firmware broken the RLC-510A completely, it is firmware problem. Because the website show it works motions at night.

Many Thanks,

Hi Cynthia,

Thanks for your reply.
As you have more experience can I ask:
1. what's difference between B400 and RLC-510A?
2. RLC-510A better than B400?

Regards,
