How to Calculate Expected Data Usage for Long-Term Construction Timelapse

Fail to calculate your data usage before a project and you can be in for a shock.

Fast forward to your first data bill, and your charges are a digit or two longer than you expected.

It’s a situation no photographer wants to find themselves in, and it can really cut into your bottom line.

So, save yourself the grief by calculating your predicated data usage.

The equation itself is simple:

photo file size   x   photos uploaded in a month   +   10% buffer
=   monthly data requirement

To make it even easier, we’ve done the hard work for you with the calculator below.

Just put in your numbers to calculate your estimated monthly data usage.

And, for more detailed help on planning your data usage, read on below.

Photo File Sizes

The size of JPEG files varies depending on the camera, the image settings, and the complexity of the scene.

The best time to check file size is during pre-installation testing.

To determine your JPEG file size, simply take some photos with your desired settings and check the size of the files.

If you can’t photograph the actual job site, take photos of a range of scenes and use the largest file size as your guide.

A word on shooting RAW: We don’t recommend uploading RAW photos, as they tend to be large files that will make your data costs sky-rocket.

You also can’t view RAW photos on the online web gallery, so there’s not a lot of benefit to uploading them.

If you want to shoot RAW, it’s best to save the RAW files to the on-board SSD for periodic manual collection.

Photo Uploads and Client Expectations

The frequency of shooting and photo uploads is something to discuss with your client.

Is your client satisfied with less frequent uploads, every thirty minutes or hour?

Or are they expecting more frequent vision of their site, every ten or even five minutes?

Your client’s requirement is going to affect your data costs, so make sure you reflect that in your fees.

Consider charging a higher monthly fee for shorter upload intervals.

This will push data costs back on to them and not on your bottom line.

If available, you can also connect your timelapse system to LAN, and not have to worry about your data costs at all. 

Shoot Only On Work Days

Make sure to discuss with your client which days of the week the construction site will be active.

Five days is common, but some projects may be active for six or even seven days a week.

In the photoSentinel Setup Portal you can select which days to shoot.

Uncheck the non-work days so you’re not uploading photos when nothing is happening on site.

Build In Some Buffer

Once you’ve calculated your data usage, don’t choose a plan that only just meets the minimum requirement.

For example, if you calculate that your data use per month is going to be about 4.8GB, you may begin eyeballing a 5GB plan.

Avoid that temptation; unforeseen variables can spike your data usage.

A client might come to you wanting to ramp up the photo frequency.

Or a period of busy activity demands shorter intervals to capture all the action.

Network dropout can also result in multiple upload attempts before a photo uploads successfully.

We recommend you give yourself a 10-20% buffer on your data plan so that you don’t have to stress about going over.

(The calculator above adds a 10% buffer.)

Selective Uploading

With the photoSentinel Mach II you can choose to upload only some photos, by setting the upload frequency to be less that the shooting frequency.

The large SSD storage of the Mach II Premium package also gives you flexibility in managing your files and data costs.

You can upload at less frequent intervals, saving some or many photos straight to local storage for collection at a later date.

You can also remotely change the upload frequency at any time, based on how your data usage is tracking.

Confidence in Your Data Budget

It’s worth setting aside the time to calculate your data usage.

Double check you haven’t failed to ‘carry the one’ somewhere.

It’s a simple process, but time and again we’ve seen photographers caught off guard by a hefty cellular data bill.

Take a few minutes to calculate your data requirements and your budget, and keep your bottom line safe from blowouts.
