Spypoint Flex-M2 review: the free-plan camera that hops carriers

Eighty dollars, two SIMs, a GPS locator and a plan that costs nothing for 100 photos a month. The Flex-M2 is the cheapest cellular camera we'd put on a marginal-signal set. What it isn't is fast or no-glow.

Who it's for

The person adding a third or fourth camera without adding a third or fourth monthly bill. A scrape, a mineral lick, a feeder that runs at dawn: places where 100 downsized photos a month tells you what you need and where a 0.4 s trigger doesn't cost you the shot. And anyone whose spot sits at one bar on the carrier their current camera uses.

Dual SIM: the reason to buy it

Spypoint's page: "Dual-SIM technology automatically connects you to all major carriers and the strongest signal in the area." Spypoint's own comparison table marks the older Flex-M as single-SIM, with "Multi-Network Dual SIM" only on the M2, Dark and S-Dark. On a set where the tower is on the wrong carrier, a single-SIM camera is a paperweight; a dual-SIM one connects. That's the $20 the M2 costs over the M, and it's the best $20 in the category. It also adds the "GPS locator on the in-app map." More on weak-signal sets in best for low signal.

0.4 s, 90 ft, low-glow: the limits

Figures as published by the maker or the named listing body; each value links to its source. A dash means the figure isn't in our cited sources.

Spypoint publishes 0.4 s, 90 ft detection, 90 ft flash, low-glow LED, 32MP, 1080p with sound. Every one of those is a step behind the Flex-Dark (0.3 s, 100 ft, both arrays, 40MP). At a feeder, none of it matters. At a crossing, a tenth of a second is about a foot of deer at walking pace, and low-glow means a faint red dot at night that a pressured buck may notice. Treat the M2 as the camera for the sets where speed and invisibility don't decide the picture.

AA, LIT-22, panel

Spypoint's series page: the M2 "runs continuously for up to 12 months with a LIT-22 rechargeable lithium battery or up to 6 months with AA batteries." The LIT-22 (7.4V, 5.4Ah, $49.99) slides in after you remove the AA tray. The 10W SPLB-22 panel (15,000 mAh bank, four cords, $129.99) covers all Spypoint cameras. Those "up to" figures are Spypoint's; what a set actually gets depends on how many photos it sends and how cold it is. Battery life explained shows how to estimate it.

The free plan, honestly

One hundred photos is about three a day. On a scrape in October that's plenty; on a feeder at dusk with does and fawns cycling through, you'll hit it in a week and the camera stops sending until the month rolls over. The fix is the $4/mo annual Basic tier (250) or the app's transmission settings: send once a day, downsized, and let the SD card hold the rest. Details in Spypoint plans explained.

Flex-M vs Flex-M2

Same 0.4 s, 90 ft, 32MP, low-glow, 1080p, same plan, same 2-year warranty. The M2 adds dual SIM and the GPS locator for $20 ($79.99 vs $59.99 on Spypoint's pages). The M is the right buy only if you know your carrier is strong at the tree and the $20 matters more than a locator. Everything else points to the M2.

A note on security boxes

CAMLOCKbox's Spypoint reference lists Box 10 for the Flex, Flex G-36, Flex-M and Flex-Dark and states it "does not fit Flex M2." If a steel box is part of your plan, check CAMLOCKbox's current reference for an M2-specific box before assuming one exists. See best security boxes.

What the spec sheet supports

  • Dual SIM picks the stronger carrier, the single biggest fix for spotty signal
  • Free 100-photo tier and the cheapest verified unlimited annual plan ($10/mo)
  • GPS locator in the app
  • $79.99 on Spypoint's page; a 2-year warranty on a budget camera

Where it falls short

  • 0.4 s trigger and 90 ft range trail the Flex-Dark's 0.3 s and 100 ft
  • Low-glow only
  • CAMLOCKbox notes its Flex box 10 does not fit the M2, so check fit before buying a security box

Skip this if…

you need no-glow; the Flex-Dark adds no-glow LEDs, 0.3 s and 100 ft for $40 more on the same free plan.

How we scored this

Cameras we claim to have field-tested: none we don't own

Plenty of sites say they hung every camera on this list in a tree for a season. We don't say that, and we say so on every page. What we do instead: read the maker's published trigger speed, flash type, battery configuration and detection range; verify each brand's plan tiers on its own plan page and compute the real monthly cost at one and four cameras; cite the independent shootouts (Trailcampro, Outdoor Life, Field & Stream, TechGearLab) as their measurements, never ours; and score every pick on a public rubric. Every figure links to where it came from.

Scores are editorial judgments from that documented research, not lab results. Commissions never set a score or decide a pick. The rubric and its weights are published.

Questions

Frequently asked

Is the Spypoint Flex-M2 worth it?

For a feeder, scrape or mineral site, especially on marginal signal or on a budget, yes: dual SIM, GPS locator, 2-year warranty and a free 100-photo plan for $79.99. For a trail crossing or a pressured set, spend $40 more on the Flex-Dark.

Does the Spypoint Flex-M2 have a free plan?

Yes: 100 photos per month per camera at $0, with no activation fee, per Spypoint's plan page.

What is the difference between the Flex-M and Flex-M2?

Dual SIM and a GPS locator on the M2; otherwise identical published specs, plan and warranty. $20 apart on Spypoint's pages.

How long do the batteries last in a Flex-M2?

Spypoint's claim: up to 6 months on AAs, up to 12 months on a LIT-22 lithium pack. Real results depend on photo volume, night activity and cold.

We don't claim to have field-tested these cameras and we don't pretend to. Specs come from the maker's own product pages (linked on every product), plan prices from the maker's plan page with an “as of” date, and independent measurements are attributed to whoever made them. Amazon prices change often, so we don't print them. Where a figure isn't published, we say so. Read the full method.
