Predation Control Equipment

Each estate will have special needs or features so a mix of technologies is often called for. All the equipment listed below is suitable for trap monitoring.

Long distance data transmission is sometimes required e.g. for a part time keeper who lives several miles from his ground. A mobile phone network can be used here with radio links covering areas with no mobile phone signal. Several traps can be connected to one transmitter by cable of any length and this reduces the cost per trap.

However, an “Alert” from that transmitter will require all of its traps to be inspected manually; so in practice a group of more than 6 connected traps over 100m radius is likely to be clumsy & difficult to manage.

Camerachecker – Colour Photos and Infra Red images by night

This has a very small digital camera activated by a sensor or by a text message instruction from the operator.

Pictures are sent immediately by email to a mobile phone or to a PC for storage; using mobile phone networks.

There are no clicks or whirs to give away its location.

Useful Applications:

  • Detecting unwelcome visitors and photographing them for identification and prosecution evidence, if necessary.
  • Predator surveillance. Distinguish between badgers, foxes & hares.
  • Where visual inspection is needed.

Range anywhere with mobile coverage.


One or more traps, fitted with sensors, are connected by a small cable to a radio transmitter which checks and reports 20 times a day to a radio receiver. A receiver station handles the data from up to 100 transmitters, records everything and indicates which units need a visit on that day.  Transmitters on trap sites can be 3 – 5 miles from the receiver, if there is clear line of sight.

Size of transmitters:  6 inches x 3 inches x 3 inches high (8.5 inches including antenna).

Powered by 4  AA batteries which last about 3 months

Receiver and its SMS unit powered by 12v battery which can be kept charged by solar panel or small wind generator.

Easily painted or wrapped for camouflage.

Signal is not affected by dense woods but it is stopped by rising ground. Ideally sited to beam across a valley or bowl shaped moorland to a receiver.

Mobile phone networks can carry the data away from the receiver to a mobile phone anywhere.  If no mobile phone network coverage, the data can be downloaded direct from the receiver onto a hand-held device.

Security applications and trapping in sensitive areas of public access.  Where a rapid response is required an Immediate Alert option can be selected to direct you to where a trap sensor has been activated.


This is the lowest cost ATC device but only usable where there is a reliable mobile phone signal.

Call the number of this adapted phone and if you hear it ringing, nothing has changed at the trap.  The trap sensor is wired to cut the phone’s power supply if there is any movement at the trap. Failure to ring, or any network recorded announcement indicates a catch or a fault and therefore a visit is required.

Malicious tampering and resetting the phone is prevented by a PIN number.

There are no call charges for the caller or the device because the call is never answered.

If a large number of Phonecheckers are used a PC operated automatic dialling system can be used.
