Often use battery-powered transmitters which are easier to install and have less expensive start-up costs, but may reduce the reliability of the system if the batteries are not maintained. Depending on distance and construction materials, one or more wireless repeaters may be required to get the signal to the alarm panel reliably. A wireless system can be moved to a new home easily, an advantage for those who rent or who move frequently. The more important wireless connection for security is the one between the control panel and the monitoring station. Wireless monitoring of the alarm system protects against a burglar cutting a cable or from failures of an internet provider. This full wireless setup is commonly referred to as 100% wireless.

The trigger signal from every sensor is transmitted to one or more control unit(s) either through wires or wireless means (radio, line carrier, infrared). Wired systems are convenient when sensors (such as PIRs, smoke detectors, etc.) require power to operate correctly, however, they may be more costly to install.

We offer a walkie-talkie (more formally known as a handheld transceiver, or ht) is a hand-held, portable, two-way radio transceiver. Its development during the second world war has been variously credited to donald l. Hings, radio engineer alfred j. Gross, and engineering teams at motorola. Similar designs were created for other armed forces, and after the war, walkie-talkies spread to public safety and eventually commercial and jobsite work. Major characteristics include a half-duplex channel (only one radio transmits at a time, though any number can listen) and a "push-to-talk" (ptt) switch that starts transmission.

We are offering conventional fire alarm. Conventional panels have been around ever since electronics became small enough to make them viable. Conventional panels are used less frequently in large buildings than in the past, but are not uncommon on smaller projects such as small schools, stores, restaurants, and apartments.

The resolution of cameras in this system is limited to vga (0.3 megapixel) and the number of cameras in the system is limited to 32 (usually we suggest 16 maximum). The cabling is complex, as separate cable has to run from each camera to the dvr. There is a requirement of separate power supply for each camera for the day & night operation.
