Choosing the best wireless nanny camera can be a little intimidating to the uninitiated. But to be honest – there is really nothing at all to be concerned about. Technology has grown in leaps and bounds – and with it an ease of use that has lowered the learning curve tremendously.
Wireless Nanny Cam Power
One of the first things that we need to keep in mind with a wireless nanny cam is how they get their power without wires? You guessed it! The power is usually supplied by batteries in some type of battery pack. Keep in mind that there are some types of battery packs that are simply thrown away when the battery charge is depleted. My suggestion would be to stay away from these throws away types and look out for a rechargeable option. This would definitely not be an area for you to try cut costs! Choose one of the rechargeable models that is in the middle of the road or top of the line as far as price is concerned. Expect to spend around $25.00 or so for a decent charger set up. Expensive? Not at all – relative to the security and peace of mind that a decent setup is going to provide to you. Trust me on this one.
Nanny Cam Transmitter
One of the next basic pieces of equipment that you are going to need for your wireless system is some sort of transmitter. This transmitter is what is necessary to get the video signal from the spy camera to your receiver/recorder/dvr (Digital Video Recorder). The majority of these will be 2.4 GHz – don’t worry too much about all of the technical jargon. Simply keep in mind that the type of transmitter that comes with your device will be the deciding factor in how far your wireless spy camera can be from the receiver. Even the lower powered models should not have any problem sending a signal 250 feet. There are higher powered models that can send the signal up to 2500 feet or more! If the distance is too far for the type of transmitter that you have, then the video signal will be distorted, faint, or non-existent. I would not suggest a transmitter that transmits a signal on a frequency lower than 2.4 GHz. Keep in mind that you want to keep all other wireless devices that transmit at 2.4 GHz – such as some cordless phones – away from your security camera due to POSSIBLE interference.There are many good companies out there that will sell you a package unit containing the wireless nanny camera AND the 2.4 GHz transmitter. This is obviously a great option – depending on the price!
Nanny Camera Receiver
One of the most important parts of your system will be the receiver. Will you need to record? Or simply observe? Will you record on cassette tape or use a dvr? There are plus and minuses to all of these possibilities that we will be dealing with in another article. But for now, the most important thing to know is that if you decide to record on cassette tape – you will need to take into consideration the deterioration of the tape. It WILL deteriorate. The speed of deterioration will be a factor of storage, ie. temperature, and exposure to light. Another disadvantage to the cassette is the inability to skip to a precise moment of time.
There is no such problem of deterioration with digital storage devices. It is also much easier to use when gathering evidence and searching for a particular moment in the storage. It is usually considered to be the better form of storage. All of the benefits – without all of the disadvantages to go along with it!
In future articles we will be dealing with other aspects of a nanny cam system – such as particular types of wireless nanny cameras, the cost of these devices, and where are some of the better places to purchase them.
