Remote trap monitoring systems compared
There are three ways to monitor a trap remotely: a sensor tag on a trap you already own, a cellular trail camera pointed at the trap, or a trap with monitoring built in. Tags are the cheapest way to learn a door closed. Only a built-in system shows you what is inside and lets you open the door from your phone.

Sensor tag, trail camera or built-in monitoring
| OcuTrap R2 (built in) | Sensor tags (Trapmate, PerdixPro, TrapSmart) | Cellular trail camera | |
|---|---|---|---|
| What it is | A cage trap with camera, cellular radio and door motor built in | A sensor you attach to each trap you own | A game camera aimed at the trap |
| Tells you the door closed | Yes | Yes | No, it only sees motion |
| Shows what is inside | Yes, a photo with every trigger | No (PerdixPro can pair a separate camera) | Yes, but on any motion |
| Release a non-target remotely | Yes, open or close the door from the app | No | No |
| Works with traps you own | No, it is the trap | Yes | Yes |
| Connection | LTE-M cellular, GPS location | Cellular per tag, or radio to a hub (varies by brand) | Cellular |
| Hardware | $499 per trap ($399 each in 5-packs) | About $99 to $109 per Trapmate sensor; hubs extra | About $60 to $200 per camera |
| Plan | $29/month per active trap or $225/year per active trap | About $7 to $20 a month per tag | Free to about $23 a month per camera |
| Team access | Team roles and shared traps, no per-seat fee | Varies (PerdixPro includes unlimited users) | Usually one account |
| Best for | Non-target risk, long drives, TNR and team fleets | Many traps where a closure alert is enough | Watching one trap you can see clearly |
What the OcuTrap plan pays for
A sensor tag plan pays for one thing: a message that a door closed. The OcuTrap plan ($29/month per active trap or $225/year per active trap) covers the cellular connection plus everything you can do with it:
- A photo with every trigger, so you know whether it is the target, a neighbor's cat or an empty misfire before you drive.
- Remote door control to release a non-target from your phone, without a trip or a reset visit.
- Alerts by push, SMS or email for each person on your team, set per user.
- GPS and capture history for every trap, with time-stamped photos for your records.
- Team roles and shared traps across the app and console, priced per active trap, not per seat.
The honest trade-off: OcuTrap costs more per trap than a tag, and it replaces a trap instead of reusing one. It earns that back when non-targets or long drives are part of your week.
When each option is the right buy
Choose sensor tags when
You run many traps you already own, you only need to know when a door closes, and non-targets are rare. Tags are the lowest cost per trap. Rodent and kill-trap programs are their natural home.
Choose a trail camera when
You have one or two traps in clear view and already own a cellular camera. Expect photos on any motion, and plan to visit to confirm the trap fired.
Choose built-in monitoring when
A wrong catch matters: pets, community cats or protected species. Or the trap is far enough away that a wasted trip costs real time. TNR programs use the photo to confirm the right cat before they drive, and wildlife operators use remote release to clear non-targets between visits.
The sensor brands, briefly
Trapmate sells the Kiwi and Kiwi+ cellular sensors (one per trap, door magnet and vibration sensing) and a hub system with sensor 5-packs, aimed mainly at rodent control professionals. Kiwi+ plans run from $19.99 a month month-to-month to $9.99 a month on a one-year term.
PerdixPro makes cellular trap tags with a strong trap management app and unlimited users. Plans run $7 to $10 a month per tag depending on term. Photos need a separately paired trail camera.
TrapSmart sells a sensor that clips onto the door of an existing trap and sends text and email alerts on a monthly plan.
CatchAlive makes NB-IoT trap alarms in Denmark; its online store ships to European countries.

Common questions
Is a camera trap with a monthly plan worth it compared to cheap trap sensor tags?
It depends on what a wasted trip costs you. A sensor tag at about $7 to $20 a month tells you a door closed. The OcuTrap plan ($29/month per active trap or $225/year per active trap) adds a photo of what is inside and remote door control, so you can release a cat, pet or other non-target from your phone instead of driving out. If you rarely catch non-targets and your traps are close by, a tag is the cheaper answer. If one avoided drive a month covers the difference, the built-in camera pays for itself.
Are Trapmate or TrapSmart sensors enough, or is a cage trap with a built-in camera better?
Sensors are enough when all you need is to know that a door closed, especially across many traps you already own. They cannot show you what is inside or open the door. A trap with a built-in camera and remote door control is better when non-targets are common, when the drive to the trap is long, or when you need a photo record of each capture.
Can a trail camera replace a trap sensor?
Not reliably. A cellular trail camera sends photos when something moves, so you get pictures of wind, birds and animals eating the bait, and it cannot tell you the door is closed. It works for watching one trap you can see clearly, but you still need to visit to know the trap fired and to release anything inside.
Do I need Wi-Fi at the trap?
Not for OcuTrap or the cellular sensor tags. OcuTrap uses LTE-M cellular, the same kind of network your phone uses. Hub based sensor systems need the hub within radio range of each trap, and some sensor brands are sold only outside the U.S., so check coverage and availability before you buy.
Can I add OcuTrap to the traps I already own?
No. The OcuTrap R2 is a complete cage trap with the camera, cellular radio and door motor built in, so it replaces a trap rather than clipping onto one. If you want to keep your existing traps and only need closure alerts, a sensor tag is the better fit.
