Moultrie Edge Solar vs Spypoint Flex-S-Dark: the panel is the same idea, the bill is not

The short version

Spec sheet, side by side

On paper the two are closer than the price suggests. Both publish 100 ft detection, 100 ft flash range, 40MP stills and 1080p video, and both auto-select a carrier. The Edge Solar is 0.40 seconds to trigger and the Flex-S-Dark is 0.30, which is a real difference on a crossing and irrelevant at a feeder. Everything that actually separates them is in the three sections below.

Low-glow vs no-glow

Moultrie's spec table for the Edge Solar reads "Low-Glow." Spypoint's for the Flex-S-Dark reads "Low-glow and no-glow LEDs," two arrays in one body, and it placed sixth overall for flash range in Trailcampro's 2026 shootout.

Low-glow means a faint red dot visible at the camera at night. Deer notice it less than people assume and people notice it more than you want, which is why the distinction is mostly about who else walks your ground. On leased timber with other hunters on it, on a gate, or anywhere a camera disappearing would hurt, the invisible array is worth the money by itself. On a back-forty food plot nobody else can reach, it is a feature you will never use. The full trade-off, including the image-quality cost of invisible IR, is in no-glow vs low-glow.

One note on the Flex-S-Dark's dual arrays: having both means you are choosing per set rather than per purchase. Run low-glow where you want the better night image and switch to no-glow on the sets that need to vanish.

What each panel actually carries

What we can say is that 2,600 mAh is small. For scale, the Spypoint SPLB-22 external panel carries 15,000 mAh and the Tactacam folding panel 4,900 mAh. A 2,600 mAh buffer behind a 2.5W panel means the Edge Solar is living hand to mouth: in good sun it never runs down, and in a shaded week in November it will. The Flex-S-Dark's unpublished pack is probably larger given the camera's size and price, but "probably" is not a number.

Both cameras have a way out. The Edge Solar takes USB-C, so a POWER MAG pack or the 3.4W Solar Power Pack II can back up the built-in panel. Spypoint's cameras take the SPLB-22, which is the better answer in shade because you can hang 10 watts on a sunny tree 6 feet away and leave the camera facing the trail. That is the whole argument for an aimable panel over a bonded one, and it is why neither of these cameras is the right pick for deep timber.

Five years of plan cost

Run that out on one camera. The Edge Solar at $99.99 plus five years of Standard at $8.99 is $639.39. The Flex-S-Dark at $149.99 on the free tier is $149.99, and at $4/mo annual Basic it is $389.99. Even on Spypoint's unlimited annual tier at $10/mo, five years comes to $749.99 against Moultrie's $879.39 on Unlimited. There is no volume of use at which the Moultrie is cheaper to own.

The free tier deserves a caveat, because 100 photos a month is genuinely restrictive: that is roughly three a day, which a single active trail will blow through in a weekend. It is a real plan for a camera watching a gate or a shed, and it is not a real plan for a camera on a well-used crossing. But it exists, and that changes the arithmetic for anyone running several cameras where only one or two are busy. The cross-brand version of this math is in cellular plans compared, and if you are costing out a four-camera set start with plans for multiple cameras.

Built-in memory vs microSD

The Edge Solar has built-in memory and takes no SD card; the Flex-S-Dark takes a microSD. This is a smaller decision than it looks, but it cuts both ways. No card means nothing to corrupt, nothing to forget in the truck and nothing to pull in the dark, which is the whole appeal of the Edge line. It also means there is no local copy you can walk up to and read if the camera stops transmitting, and no archive beyond what the app holds.

With the Spypoint you keep the card as a backstop: the full-resolution originals sit on it even when the app only ever showed you compressed thumbnails, which matters if you ever want a printable frame of the buck. Card choice and formatting is covered in the SD card guide.

Prices and stock on 2026-10-09

Moultrie listed the Edge Solar at $99.99, down from $129.99, and in stock. Spypoint listed the Flex-S-Dark at $149.99 and out of stock, with a notify-me option. Trailcampro had the Flex-S-Dark in stock at $169.95. Amazon had it in stock too, but at a third-party price well above Spypoint's own, which is the sort of listing you should walk away from.

So the honest state of play on the day of writing: the Moultrie is the one you can buy at list today, and the Spypoint is the better camera you may have to pay $20 over list for or wait on. If you are not in a hurry, the Spypoint restocks. If you are hanging a camera this weekend, the Edge Solar is in stock at $99.99 and nothing in this comparison says it is a bad camera, only an expensive one to keep.

Who should buy which

• Buy the Flex-S-Dark if you want invisible IR, a faster trigger, a card you can read, and a plan bill you control. It is the better camera and, past six months, the cheaper one.
• Buy the Edge Solar if $99.99 is the number that has to work, you are already inside the Moultrie app with other Edge cameras, and the set is a feeder or a plot in open sun where 0.4 seconds and a red dot cost you nothing.
• Buy the Edge 4 Solar if you are set on Moultrie but the Edge Solar's spec sheet bothers you. It is the Moultrie solar body worth the money, and it was in stock at around $150 on Amazon when we checked. If you can live without the panel, the Moultrie Edge 3 Pro is the better camera for the same money.
• Buy neither if the set is in deep timber. A bonded panel needs sun on the camera. Hang a no-glow camera with an aimable 10W panel on the sunny tree instead, or run a 12V box.
