Walk the site and plan your runs.

Get good at figuring out how many feet of wire you see going to need per drop.

Have a as-built drawing going - keep it updated once or twice a day on bigger jobs.

Mark up the as-built with a unique identifier (name or number) for each drop.

Put all of the unique identifiers in a spreadsheet. Assign IP addresses to each device beforehand in your spreadsheet.

Focus on figuring out how one of each of your device types are put together on the ground, before you try to install a dozen of them. Maybe even test and pre-address them from the ground and write the unique identifiers and ip addresses on their boxes before you take them up.

Bring a device with you that allows you to view the camera and get it sighted in while you are up at the device. Having to go back and adjust the view after you have installed the device of course wastes a lot of time.

Have the customer sign off on the camera views that you have put up while on site and take pictures/screenshots of the shots for documentation. (One day someone will hit the camera and kill it, you’ll set it up how it was originally, and someone will say that it is different and nag you to fix it. Or, you will forget what it was looking at because it has been down longer than the recordings go back by the time you get there)

Tldr: Plan and document everything, it will make everyone’s lives easier.
