Quick Answer: Four trail camera accessories are not optional: a mount (HME Trail Camera Holder Strap-On, $27.99, or a cheaper screw-in for private land), batteries (Energizer Ultimate Lithium AA, which TrailCamPro’s cold-weather test measured at 97% capacity retention at 5°F versus 33% for alkaline), an SD card sized and speed-rated for your camera (32GB SanDisk Ultra for older cameras, SanDisk Extreme microSDXC U3/V30 for 4K), and theft protection — a CAMLOCKbox security case ($35.99-$49.99) plus a Master Lock Python cable ($24.95) — if the camera sits anywhere you don’t fully control. Solar panels, signal boosters, and tripods are situational upgrades that solve one specific problem each. GPS trackers, camo skins, and SD card viewers are the three most-marketed accessories you can usually skip; the sections below explain exactly when each one actually earns its price.
Trail camera buying guides tend to recommend every accessory in the catalog, because every accessory in the catalog has an affiliate link attached to it. This one ranks them instead — by how much they actually change what your camera does — and says plainly which ones most buyers don’t need. For the cameras themselves, start with our best trail camera rankings; this guide picks up once the camera is already in the box.
Trail camera accessories by the numbers
- Roughly $1.48 million in camera-trap equipment was lost to theft and vandalism between 2010 and 2015, per a 407-respondent international survey by Meek et al. (2019) in Remote Sensing in Ecology and Conservation — the reason theft protection sits in the “essential” tier below rather than the “situational” one.
- 97% versus 33%. TrailCamPro’s controlled cold-weather test measured Energizer Ultimate Lithium AA batteries retaining 97% of room-temperature capacity at 5°F, against 33% for a standard alkaline cell — the single biggest performance gap of any accessory on this list.
- SanDisk rates its 256GB High Endurance card for up to 20,000 hours of Full HD recording, per SanDisk’s own product specs — the difference between a card built for a camera that writes constantly and one that just happens to be fast.
- A 3.4W solar panel needs about 40 minutes of direct sun a day to keep a cellular camera running indefinitely, per Moultrie’s own spec sheet for its Mobile Solar Power Pack — which is why solar only pays off on a camera you can’t easily reach to swap batteries.
Trail camera accessories, ranked by priority
| Accessory | Tier | Top pick | Price | Buy it if... |
|---|---|---|---|---|
| Mount | Essential | HME Strap-On | $27.99 | Always — every camera needs one |
| Batteries | Essential | Energizer Ultimate Lithium AA | ~$15-20 / 8-pack | Always — the box set rarely lasts a season |
| SD card | Essential | SanDisk Extreme microSDXC | ~$18 / 128GB | Always — the included card is usually tiny or missing |
| Security box + cable | Essential if exposed | CAMLOCKbox + Master Lock Python | $35.99-$49.99 + $24.95 | Public land, rentals, or any site you don't control |
| Solar panel | Situational | Moultrie Mobile 3.4W | $59.99 | Cellular camera, or a site you can't visit monthly |
| Signal booster | Situational | SPYPOINT CA-01 antenna | $39.99 | Cellular camera with 1-2 bars, not zero bars |
| Tripod | Situational | Amazon Basics 60-inch | ~$22 | No tree, post, or fence at the site |
| GPS tracker | Usually skip | LandAirSea 54 | $29.95 + plan | Only remote/public land, and only if the camera lacks built-in GPS |
| Camo skin | Usually skip | Mossy Oak Game Camera Skin | $9.95 | Cosmetic only — the lockbox is the real security, this isn't |
| SD card viewer | Usually skip | — | $15-25 | Only if you run a non-cellular camera and hate using a laptop |
The 4 essentials
1. A mount
HME Trail Camera Holder Strap-On (HME-TCH-SO)
- Ratchet strap instead of a tree screw — HME's own product page notes screwing into trees is illegal on most federal, state and county forest land.
- 360° rotation and 120° tilt on the standard 1/4-20 stud every current camera and solar panel uses.

A mis-aimed camera is the single most common reason a season of cards comes back empty, and most cameras ship with a basic bungee that works only on a straight tree you visit often. If you hunt or run cameras on public land, the strap-on is not optional — see our full best trail camera mount guide for screw-in, ground-stake, T-post and magnetic alternatives depending on what you’re mounting to.
2. Batteries
Energizer Ultimate Lithium AA (L91)
- 97% capacity retention at 5°F in TrailCamPro's controlled test, versus 33% for a standard alkaline AA.
- 25-year shelf life per Energizer's datasheet — buy a season's supply at once without worrying about dead stock.
The box-included AAs die fast, and alkaline’s cold-weather collapse is the most-documented failure in this entire category. Our full best trail camera battery guide covers why some manufacturers still warn against rechargeables, and which manufacturer battery packs are actually worth the upgrade over loose AAs.
3. An SD card
SanDisk Extreme microSDXC
- Fast enough for 4K clips per the SD Association's U3/V30 speed-class spec, and compatible with nearly every current cellular and standard camera.
- For older cameras capped at 32GB/FAT32, a plain SanDisk Ultra 32GB is the guaranteed-compatible budget pick instead.
The included card, when a camera ships with one at all, is usually too small or too slow for 4K. Our best trail camera SD card guide breaks down capacity limits, speed classes, and the high-endurance cards worth it for always-on or heavy-video cameras. If you’re buying several budget cameras at once to cover a property — a common move with brands like WOSports that sell cheap multi-packs — budget one card per camera rather than assuming a single card covers the whole setup.
4. Theft protection — if you’re exposed
CAMLOCKbox Security Case + Master Lock 8418D Python Cable
- 16-gauge powder-coated steel case cut to your exact camera model, plus a 6ft braided-steel cable lock that threads through the box.
- Needs a heavy-duty swivel bracket (not a standard mount) to carry the added weight — Reconyx states this directly on its own mount page.
This is the one accessory on the “essential” list that genuinely depends on where your camera sits. On fenced private land you check weekly, skip it. On public land, a rental, or any spot strangers can reach, the $1.48 million Meek et al. documented in losses makes the $60 combined cost an easy call. Full breakdown, including which boxes fit which camera models, in our best trail camera security box guide.
3 situational upgrades
Solar panel — buy it if your camera is cellular, or sits somewhere a monthly battery-swap trip is a real chore. The best trail camera solar panel guide’s top pick, the Moultrie Mobile 3.4W pack, needs only about 40 minutes of direct sun a day per Moultrie’s spec sheet. Skip it on a camera over your back door that you pass daily anyway — that $59.99 buys a second budget camera instead.
Signal booster — a passive antenna like the SPYPOINT CA-01 ($39.99) adds a bar or two where a cellular camera already gets weak signal. It does not create signal where there is none; our best trail camera signal booster guide explains why active cellular boosters (the “weBoost” style) don’t work here at all — they need continuous 110V or 12V power a tree mount doesn’t have.
Tripod — only relevant when there’s genuinely nothing to strap or screw into: a food plot, a driveway, a deck. The best trail camera tripod guide’s Amazon Basics pick (~$22) covers that gap. If there’s a tree, post, or fence anywhere nearby, a $20-28 mount is cheaper and far less visible than a tripod standing in the open.
3 accessories you can usually skip
GPS tracker. A standalone unit like the LandAirSea 54 ($29.95 device, $9.95-$49.95/month) only earns its keep on remote or public land with a real theft history — and it’s worth checking your camera model first. The best trail camera GPS tracker guide flags that the Tactacam Reveal Pro 4.0 and VOSKER VKX already ship with GPS theft-tracking built in, which makes a separate tracker a duplicate purchase on those models specifically.
Camo skin. The Mossy Oak Matte Camo Game Camera Skin ($9.95) is a fine $10 upgrade and our best trail camera camo guide ranks it first — but it’s cosmetic. It changes how visible the camera is to a person walking by, not whether it survives contact with one. The security box and cable above are the actual theft deterrent; treat camo as the optional finishing touch, not a substitute for it.
SD card viewer. A handheld card reader is genuinely useful if you run a non-cellular camera and don’t want to carry a laptop into the woods. But cellular cameras already push photos to your phone, and plenty of hunters are fine plugging a card into a laptop at home. It’s a convenience accessory, not a gap in your setup — worth the $15-25 only if you’ve actually felt the annoyance it solves.
Which accessories should you actually buy first?
- Every camera, no exceptions: a mount, a set of Energizer Ultimate Lithium AAs, and an SD card sized to your camera.
- Any site you don’t fully control: add the CAMLOCKbox + Python cable pair before anything else on this list.
- Cellular camera, hard to reach: add the solar panel next; add the signal booster only if you’re already getting partial bars.
- No tree, post, or fence at the site: a tripod, not a mount.
- Skip for most buyers: a standalone GPS tracker (check for built-in GPS first), a camo skin (cosmetic, not security), and a card viewer (convenience, not necessity).
The bottom line
Four accessories are worth buying with every trail camera: a mount (HME Strap-On, $27.99), Energizer Ultimate Lithium batteries, a properly sized SD card (SanDisk Extreme microSDXC for most, plain SanDisk Ultra 32GB for older cameras), and — only where theft is a real risk — a CAMLOCKbox security case ($35.99-$49.99) with a Master Lock Python cable ($24.95). Meek et al.’s documented $1.48 million in camera-trap theft losses is the reason that fourth one isn’t optional on public or unmonitored land. Solar panels, signal boosters, and tripods solve one specific problem each and are worth skipping if you don’t have that problem. GPS trackers, camo skins, and SD card viewers are the three most heavily marketed add-ons in this category and the three most buyers can leave in the cart.
