The Video Door Phone is a screening device which allows you to identify and communicate with visitors at your door. Once you can see and speak to the person that wants to come in to your home, you can open the door with confidence and without the fear of being attacked. You can also attach an electronic lock to the Video Door Phone and unlock the door by simply pressing a button. The Video Door Phone consists of an indoor monitor and outdoor camera unit. The indoor monitor has a microphone and speaker for two way audio-communication and a black & white or color monitor to view your visitor. It is installed inside your home. The outdoor camera unit also has a microphone and speaker, a black & white or color camera and a bell button. It is installed outside your main door or gate, generally where the door bell is installed. Visitors arriving at your front door or gate press a bell button on the outdoor camera unit which will sound a bell on the indoor monitor and the image from the outdoor camera appear on your indoor monitor. You can then see and talk to the visitor and decide whether you wish to let them in. The camera is fitted with an infrared light to allow you see your visitors when it is dark outside and the bell button is illuminated for easy visibility in the dark.

This detector is a small battery-operated device that scans certain frequencies looking for the signals emitted by hidden wireless security cameras. If it detects such a signal it alerts by flashing a LED light or sounding an alarm. Wireless security cameras are miniature battery-operated spy cameras that can be hidden virtually anywhere. They transmit a signal to a receiver that can surreptitiously record activity when movement triggers the camera. Commonly called "nanny cams" for their notoriety in catching abusive caretakers in the act, these cameras have also been used to unscrupulously record people in public changing rooms, hotel rooms, public restrooms, in rented apartments and houses and in a variety of settings assumed to be private. Discovering that one of these highly affordable, tiny devices is watching and recording surreptitiously is close to impossible without a wireless camera detector. A wireless camera detector, about the size of a lighter, is small enough to carry in your pocket or purse. It only needs to be switched on and slowly waved or pointed in various directions. You can walk through your home with it, bring it shopping and use it when you step into a changing stall or restroom, or switch it on anywhere else you expect a high degree of privacy. The detector will quickly confirm your trust or alert you that an intrusive wireless camera is watching. Wireless camera detectors normally scan from 50MHz to 3GHz at variable distances and channels. These devices scan radio frequency (RF) waves and cannot detect closed circuit television (CCTV). Some wireless camera detectors also locate audio bug devices. Generally these units scan a wider array of frequencies starting in the 2MHz — 10MHz range, up to 3GHz. More expensive models feature locating technology to guide you to the position of the hidden camera or bug. An alternate wireless camera detector, purportedly used by the military and now available to the public, locates both wired and wireless cams whether they are transmitting RF waves or not (i.e. whether they are turned on or off). This small device uses an array of very powerful LEDs surrounding a viewport. By looking through the viewport and depressing a button to activate the LEDs, you can slowly scan the room where cameras might be suspected. Any camera lens present, no matter how small, will create a sharp reflective pinpoint of light in the viewport. As miniaturized spy technologies have become affordable and proliferated, potentially compromising security and privacy, counter technology continues to move forward as well. Wireless camera detectors, bug detectors and cell phone detectors are all examples of this growing industry

In present days the companies and organizations have become more conscious about their security so the surveillance systems have gained a huge importance. Surveillance is the monitoring of behaviors and it includes simple, relatively no or low technology methods such as direct observation, observation with binoculars, cameras, CCTVs, postal interception, or similar methods. Many organizations today want to shore up the safety and security of their employees, visitors and students as well as their premises and assets so they are seeking for innovative, affordable alternatives that deliver rapid and appropriate responses to crimes or emergencies that may arise. CCTVs, Digital cameras and IP interfaces are being used for longer retention periods at higher resolution.
