How To Buy A Wireless Spy Camera
A Hidden Wireless Spy Camera Can Be Used for Many Purposes Including Catching Abusing Care Givers, Cheating Spouses, Nosey Landlords, Thieving Roommates, Employee Theft. 1) There are Color or black and white spy cameras. Color wireless spy cameras are better at distinguishing different items in the field of view but may be a little bit more expensive. Black and white models usually produce slightly higher resolution images and are a little bit cheaper cheaper than their color types. 2) Sensibility to low light. Measured in LUX. The lower the number the better the camera sees in low light conditions. For a spy camera to see in low light, go with a unit with a lux of 0.05 . For pitch dark covert operations opt for a lux of 0.03 . 3) Image quality. Measured in lines of resolution. The higher the number, the better the image quality. 380 lines of resolution is usually good enough even for professional private investigators. 4) Is the Receiver included? The receiver is what you connect to your TV, VCD or DVD to view the images and sound from the wireless spy camera. If the receiver is not included as part of the camera cost, ask how much one would cost and see if it fits your budget if it is an extra change. 5) Transmission frequency used. This is the frequency the wireless spy camera uses to transmit the video signal to the receiver. There are currently 434mhz, 900mhz, 1.2ghz and 2.4ghz transmission frequencies. Most good spy cameras are 2.4ghz and is sufficient for all covert surveillance operations. Because of interference, you should stay away from 434mhz and 900mhz models. 1.2ghz and 2.4ghz are the better options. 6) Transmission range Measured in 'line of sight', it is a measure of the maximum distance the spy cam can stand away from the receiver and still receive the signal with no obstruction and interference between the two. The range is usually between 300 feet and 2000 feet depending on the model. Many wireless spy cameras specify a line-of-site range and the range if there were wall obstacles present. 7) Hidden Camera or Stand Alone There are Wireless Spy Cameras that can be mini and wireless that you can attach to a pole, hide in a box or flower pot and there are mini wireless cameras that are what they call Hidden Wireless Spy Camera. These cameras are placed into ordinary looking every day objects that we see in our environment every day, like smoke detectors, lamps, teddy bears, air fresheners, mirrors and many other objects. So depending on your application, you may want to get a hidden wireless spy camera and you are all set. You still use a receiver like the stand alone spy cameras but hidden cameras are more convenient and easier to place in your home or business. WARNING: This figure can be misleading. Interference and obstruction are things you will probably be dealing with to some degree, so never accept the transmission range advertised as the real world effective range. Ask the store for a more realistic figure. So now, you now have the necessary knowledge to buy a quality wireless spy camera on your own for any number of secret covert operations so please keep in mind these 7 basic factors when choosing one. It will make the difference between getting the evidence you want on that cheating husband, abusing nanny or thieving employee and a house decoration!
