6 of 7 customers found the following review helpful: Purchase rechargeable battery , 2008-04-01 The camera's are very clear regardless of the time of day. The infrared is great except when activated little red dots appear around the lens of the camera which are visible. I have the receiver upstairs in my town house and there is no problem with the reception on a downstairs camera which i have put on the balcony. WOuld definetly recommend.
