During daylight business hours
Well Captian Obvious........
Lol your name is too easy there. I do most of my walkthroughs during daylight however interior rooms tend not to have windows therefore they require a flashlight.
Burglar alarm without response by a keyholder can lead to an insurance loss. IE our properties are insured by a special type of rental property insurance. This insurance requires response to emmergencies within a time frame. We also guarentee 10 min response time to any and all issues.
This is to say that I need to respond and investigate not that I need to go Chuck Norris and start breaking arms and legs. That is up to discretion as stated earlier in the thread if I show up to a swinging door and a moving van at midnight I am simply going to observe from a distance and alert the police.
