It’s no longer working after 1 week

Need a camera not doorbell

Used it as a gate doorbell. Worked great at first, but then stopped worked consistently. Returned

Attached the bell ringer outside the front door. Protected from rain by the extensive porch. Worked fine with very occasional usage for about 2 months, then the bell ringer failed. The cold weather? Case very difficult to open to try changing battery, so decided to try another model. Very Disappointing.
