Outdoor surveillance systems require specific performance standards. Some of them may be obvious to you, but some may not be so obvious. The basic components of indoor and outdoor surveillance systems are the same though. You may be familiar with these if you have researched the topic any prior to this. In case you haven't here is a quick overview of what typically comprises a surveillance system.
The most basic component is one or more cameras. These all video, and sometimes audio to be transmitted from the location where the camera is placed to some other location. At the point where the video and / or audio is sent there is typically a monitor and / or receiver recorder. There are some benefits of each. The monitor allows an individual stationed there to monitor activity in real-time. A receiver recorder allows the video and / or audio from the camera(s) to be recorded and reviewed at a later time. This allows monitoring even when no one is at the site. It is not uncommon to find both a monitor for real-time monitoring and a recorder. This creates documentation in addition to the witness's account that can be presented when necessary. There are any numbers of other components that can be added, but those are the primary ones.
With outdoor surveillance systems you will need to ensure that your cameras can withstand the conditions that you are placing them in. Outside there is often a chance of rain. In addition there is sometimes a chance of freezing temperatures or extreme heat. Not all electronics can operate in conditions of moisture and extreme temperatures. This is a key feature of outdoor cameras. Many are sealed to prevent moisture from getting inside. Similarly they may have hoods to protect from both light glare and distortion of the picture as a result of water running across the lens. Many outdoor cameras are also equipped with night vision. Assess the area you will be installing the camera in to determine what specifications your equipment will have to meet.
Transmission of the signal is another concern with an outdoor system. In some cases the possibility of damage to wires may exist. This may prompt a preference for wireless systems. If there is a large amount of interference or sensitive data in the signal you may not want to broadcast your signal through the air though. Weighing the practicalities of each is important.
The specifics of your installation will also determine what schedule of recording you want to initiate. You may want to consult a professional when planning your outdoor surveillance systems if you have any questions.
