GLOSSARY

CDMA- Code Division Multiple Access is a competing cell phone service technology to GSM, which is the world’s most widely used cell phone standard. Sprint, Verizon, and Virgin Mobile use CDMA.

GPRS- General Packet Radio Service was early technology to enable data communication on GSM networks. It has since been replaced by better data technologies such as EDGE and 3G. It is based on GSM and compliments SMS.

GSM- Global System for Mobile communications. Cell phones use a cellular provider’s GSM network by searching for cellular phone towers in the nearby area. GSM has more complete global coverage due to roaming and international roaming contracts. AT&T and T-Mobile use GSM.

MMS- Multimedia Messaging Service. Takes SMS text messaging a step further by allowing for longer lengths beyond the traditional 160-character SMS limit.

PIR- Passive Infrared. A PIR sensor does NOT detect or measure “heat”. It detects the infrared radiation emitted from an object to detect motion. It triggers the camera to take a photo or video when an object passes in front of the sensor.

SIM- Subscriber Identity Module. A small card used in GSM devices to identify your account to the cellular carrier. Users may change SIM cards between cameras and the phone number and data plans transfer with it.

SMS- Short Message Service. SMS is also often referred to as texting, sending text messages or text messaging. The service allows for short messages to be sent from one cellular device to another cellular device or from the Internet to a cellular device.

SMTP- Simple Mail Transfer Protocol is an internet standard for electronic mail (e-mail) transmission across Internet Protocol (IP) networks. SMTP was first defined by RFC 821 (1982, eventually declared STD 10) and last updated by RFC 5321 (2008) which includes the Extended SMTP (ESMTP) additions and is the protocol in widespread use today.
